Parts Identification 6 MFH1956E BROCK® SUPERB® Low Profile Grain Dryers SQ Installation SAFETY SAFETY Recognize SAFETY information This is the Safety-Alert Symbol. When you see this symbol on the equipment or in this Manual, be alert to the potential for personal injury. Signal words DANGER, WARNING, or CAUTION, are used with the Safety-Alert Symbol. Be sure to follow ALL National and Local Safety Standards governing each installation site. Understand signal words DANGER indicates an imminently hazardous situation which, if not avoided, WILL result in death or serious injury. WARNING indicates a potentially hazardous situation which, if not avoided, COULD result in death or serious injury. CAUTION indicates a hazardous situation which, if not avoided, MAY result in minor or moderate injury. Lockout/Tagout (LOTO) refers to the systematic procedures as outlined by OSHA (29 CFR 1910.147) for dealing with hazardous electrical energy. LOTO is the procedure by which qualified and licensed electrical personnel must abide to approach electrical testing and maintenance on these Dryers. The “Manufacturer’s Recommended Minimum Lockout/Tagout Energy Control Procedures” on Pages 77-78 incorporates LOTO steps, and is referred to several times in this Manual. IMPORTANT! When “Lockout/Tagout” is referred to in this Manual, it is always with the understanding that procedures are to be done only by qualified, licensed electrical personnel who are following the National Electrical Code plus all applicable state and local codes. ATTENTION! Dryer Contractor, Installer, Owners, Operators: Read and follow THIS MANUAL—especially this SAFETY Section! Reading and understanding this Manual is REQUIRED before Dryer usage. Keep this Manual in a safe, dry place where the Dryer Operator can easily obtain it for future reference. Contact your Brock Dealer to replace a Manual should it become lost or damaged. Restrict Grain Dryer Areas and Designate a SAFETY Zone Designate a SAFETY zone for unauthorized personnel or visitors. Provide adequate fencing and security of restricted areas. Unauthorized entrance to restricted areas around the Dryer exposes persons to hazards. This area should only be entered by authorized personnel with proper personal protective equipment (PPE). Be sure this designated area is clear before turning power on to the Dryer. Since Dryers are often installed on non-commercial farms, it is essential to keep unqualified/untrained personnel, especially children, out of the working area at all times. Accident reports stress that children must be given special precautionary attention because of their natural curiosity for exploring where the grain is going. BROCK can provide an optional “Hazardous Area” Decal which can be posted in areas where only trained Operators of the Dryer have authorized access. It is the responsibility of the Installer and/or Owner/Operator to post and comply with these guidelines and/or other governing standards that may apply. MFH1956E 7 SAFETY BROCK® SUPERB® Low Profile Grain Dryers SQ Installation SAFETY Dryer installations Damage to a Dryer can occur due to improper installations. Dryer foundation pads and/or Legs must be level and installed correctly before a Dryer is installed. IMPORTANT! DANGER! CAUTION! Improper installation of electrical or fuel sources will void the Warranty and may cause death or serious injury. Installing any non-BROCK® (another manufacturer’s) components to this Dryer WILL VOID THE WARRANTY on the BROCK® Dryer. Do not modify or attach any other equipment to the Dryer. DO NOT use tanks for liquid propane (LP) that have been used for anhydrous ammonia! This includes previously purged tanks that have been used for anhydrous. Gas train components may be damaged, causing a Dryer malfunction which could lead to serious safety hazards and/or fire. Installing any tank (for an LP fuel supply to the Dryer) which has previously been used for anhydrous ammonia poses a safety threat. Brock Grain Systems will not be held liable for any purging and cleaning methods used for such tanks. If such a tank is used, this will void the Dryer Warranty. Bypass of factory SAFETY controls and switches is strictly prohibited, and will void the Dryer Warranty. IMPORTANT! With the exception of a CONVERSION to the BROCK® QUANTUM® Controller specifically designed for use with the BROCK® SUPERB® Dryer, installing a non-BROCK® (another manufacturer’s) Controller or any other type Controller on a BROCK® SUPERB® Dryer WILL VOID THE WARRANTY on the BROCK® SUPERB® Dryer. IMPORTANT! It is the responsibility of the Contractor, Installer, Owner and Operator to supplement the Dryer furnished by Brock Grain Systems with any necessary ELECTRICAL or STRUCTURAL items to make the Dryer installation comply with the National Electric Code, National Electric Safety Code, OSHA, and all other applicable federal, state and local laws and ordinances. Contact only qualified and licensed electrical and gas contractors to install your Dryer and connect its power and fuel sources. Follow recommended precautions and safe operating practices of national and local codes at each installation site. Dryer installations shall meet the National Fire Protection Association Standard 61B for the prevention of fires and explosions in grain elevators and facilities handling bulk raw agricultural commodities. All components must meet the National Fire Protection Association Standard NFPA No. 70 (National Electrical Code), American National Standard Inst. ANSI-C1, as well as state and local requirements and/or amendments. Failure to follow these standards could result in death or serious injury. WARNING! Electrical SAFETY DANGER! Electricity can KILL! Use extreme CAUTION around electrical components. Disconnect electrical power BEFORE inspecting or servicing the Dryer. Your Installer should have your electric company check the transformer and lead wires before any installation or service work is performed on the Dryer. Be sure the wires are an adequate gauge to carry the load of your Dryer Motors, including starting and full-load operating conditions.

Brock Grain Systems neither assumes responsibility for the electrical wiring used with this Dryer; interlocking equipment EXTERNAL to the Dryer; nor will be liable for damage to the Dryer, or persons, or other property, because of improper electrical installation or use. Improper installation or use will void the Warranty. The “Service Disconnect” is sometimes located away from the Dryer in a designated electrical room on the facility. Turns power ON/OFF from the outside power service provider. Depending on local codes, it is the responsibility of the Service Provider and/or Owner to clearly mark the Service Disconnect. 8 MFH1956E BROCK® SUPERB® Low Profile Grain Dryers SQ Installation SAFETY SAFETY CAUTION! DANGER! All SAFETY devices, including wiring of electrical devices, shall be arranged to operate in a “FAIL-SAFE” manner. That is, if a power failure or failure of the device occurs, a HAZARDOUS CONDITION will not result. To prevent a hazardous condition, the machine and all associated equipment MUST be PREVENTED FROM RESTARTING on its own after a power failure when power returns or a jam is cleared. A MANUAL re-start is required. A Lockout/Tagout device/lockable disconnect switch MUST be installed on Dryer Control enclosures containing hazardous voltage wiring to prevent the Dryer from restarting during a safety check, maintenance, etc. DANGER! To guard against electrical shock, all Dryers shall have a GROUND connection. Make sure electrical equipment and the Dryer are properly installed and GROUNDED by a QUALIFIED ELECTRICIAN according to the National Electrical Code and all applicable state and local codes. DANGER! DO NOT take shortcuts or bypasses in installation by using electrical tape instead of proper means. DO NOT remove any SAFETY devices installed on the Dryer. Do not install or use any method to start or restart the Dryer which bypasses factory-installed SAFETY features. Train Dryer Operators properly WARNING! MFH1956E The Manufacturer requires that all persons who will be operating or working around this equipment be trained in proper operational and SAFETY procedures. Only Operators completely familiar with both the SUPERB® Dryer and this Manual and its SAFETY/operational practices should be permitted to operate the Dryer. This Manual is supplementary to any law or code covering fire or health regulations. It is essential that Owners and Operators use, instruct, and insist on responsible and safe operation according to published grain handling standards applicable in your local area. It is the responsibility of the Contractors, Installers, Operators, Owners and Supervisors to: • Read and follow this Manual, SAFETY instructions, and SAFETY Decals and procedures herein; • Make the above known to all who work with the equipment or who may be in the working area; • Read and follow the SAFETY procedures and Decals in your Manuals to supplemental equipment and accessories; • Know and observe proper grain industry operating precautions, practices and requirements to comply with all federal, state and local laws and ordinances and applicable SAFETY codes. This Grain Dryer is operated by AUTOMATIC CONTROLS that drive highspeed fans and rotating parts, high voltages, burners, moving augers, and other hazards. The Dryer may start without warning. Work around Dryers with extreme CAUTION! DO NOT OPERATE the Dryer with any Guards missing or removed. Failure to follow these instructions could result in death or serious injury. Failure to follow proper operational procedures may cause damage to equipment or property and/or death or personal injury. 9 SAFETY BROCK® SUPERB® Low Profile Grain Dryers SQ Installation SAFETY Even the SAFEST Dryer Poses Multiple Hazards BROCK® Dryers are designed with your SAFETY in mind. However, accidents can happen with improper installation or use of any system using a flammable fuel, high-speed moving fan wheels and high voltage. Grain Dryers by their function pose several types of significant, operational hazards that cannot be completely eliminated or safeguarded. BROCK strives to take every reasonable precaution to design equipment that is safe without compromising or restricting necessary movement of Dryer components. Installers, Owners and Operators are expected to take necessary precautions to reduce the risks associated with Dryers. Injuries or death can be caused by electrocution, gas explosions, auger flighting, fan blades, entanglement in a belt drive or power unit, or other hazards. Using this Dryer for any other purpose or in a way not within the operating recommendations specified in this Manual will void the Warranty and could cause injury or death. This Dryer is designed and built with SAFETY features. Under no circumstances shall the safety characteristics of this Dryer be altered. Practice SAFE Dryer Operation and Maintenance Make your farming business safer for all—by educating, training and emphasizing the need to avoid taking risks. Make certain a QUALIFIED OPERATOR is in attendance at all times while the Dryer is operating. If you should need to enter the Dryer (for an adjustment, inspection, etc.), enter only if you: 1. Shut off, Lockout and Tagout all power. See Pages 72 and 77-78. 2.Wear proper BREATHING equipment during cleanout. 3. Enforce a NO SMOKING policy on the premises. 4. Station trained people to help from OUTSIDE the Dryer. 5. Replace all Doors and Guards before resuming Dryer operation. Safe restarts—after emergency stops—require inspection. If a machine is stopped for unclogging, it may clog again upon the return from a RESTART. Before restarting a Dryer that has been manually or automatically shut down because of an emergency or stoppage, an inspection of the Dryer shall be made and the cause of the stoppage determined. Power to the starting device shall be shut off and LOCKED OUT before any attempt is made to remove the cause of the stoppage. Always Keep Guards on Moving Parts To avoid being struck, do not open Guards or Doors while the Dryer is running. Do not step on the Unload device. Do not attempt to poke or prod material in any moving Dryer parts with a bar, stick, or other instrument such as a common “hay hook” device. These can be hazardous. Moving parts such as fans pose a special danger of entanglement and traumatic amputation if approached or used improperly. Some parts and bearings must remain exposed to facilitate operation. DANGER! KEEP HANDS, LIMBS, ALL PARTS OF YOUR BODY AWAY from Dryer parts and openings when the Dryer is running. Severe personal injury will result if equipment is operated without Guards properly installed/latched. Do not operate the Dryer unless all SAFETY devices and Guards are in place. If the Dryer is to be opened for inspection, cleaning or observation, all Dryer power must first be shut off, LOCKED OUT and TAGGED OUT so the Dryer CANNOT be restarted by anyone remote from the area. Failure to follow this instruction will result in death or serious injury. Visually inspect the Dryer prior to operation. Correct any hazardous situation. Repair any faulty equipment. Ensure that electric motors are operating at the proper speed. 10 MFH1956E BROCK® SUPERB® Low Profile Grain Dryers SQ Installation SAFETY SAFETY Use CAUTION When Servicing EXPOSED Parts (Moving or Electrical) DANGER! Electricity can KILL! Moving parts, fires, and explosions can KILL! Use extreme CAUTION around electrical, mechanical and plumbing components of this Dryer. Always shut off, disconnect, LOCKOUT and TAGOUT all power before adjusting, inspecting servicing, cleaning, repairing, unclogging, performing any maintenance on the Dryer, or opening it in any way. If testing instructions specifically state otherwise or if power must be on to check voltage, use extreme CAUTION. Failure to follow these instructions will result in death or serious injury. IMPORTANT! Review and always follow the “Electrical Connection/Disconnection Procedures for Dryer Testing” (Page 72), and the 'Manufacturer’s Recommended Minimum Lockout/ Tagout Energy Control Procedures” (Pages 77-78) in this Manual. • • • • • • WARNING! Never enter a Dryer while in operation. Be sure all safety Doors are functioning properly to shut down power if they are open. Never enter a Dryer that has automatic unloading equipment without locking out and tagging out the control circuit. Always hire a licensed electrical contractor to repair electrical wiring, switches, fuses or electrical machinery and equipment. Shut down, Lockout and Tagout all power when replacing Fan wheels. Regularly inspect wiring, cords, plugs, tools and equipment for obvious external damage. Watch for shorts and sparks in fittings, or loose wiring. Check fuel line connections for leaks; minor leaks can go undetected a long time. Always Wear PPE (Personal Protective Equipment): Avoid noise / eye dangers, and other personal hazards. Failure to do these could result in death or serious injury. Require hearing protection around Grain Dryers (approximately 80% of all farmers have some hearing loss). Have an emergency hand-communication system in place in areas where Dryer, tractor or equipment noise is excessive. Because of the DANGER of flying debris to eyes, protective eyewear/safety glasses must be worn during assembly, installation, maintenance or servicing of this Dryer. It is important that all operators use good common sense and always be aware of and understand these additional SAFETY rules, which should be enforced: • Never wear loose-fitting clothing or flowing scarves around moving parts. Keep long hair secured. Wear suitable footwear for grain handling areas. Keep shoestrings secured. • Restrict or prohibit jewelry (some types of rings, earrings, and body jewelry) that poses an entanglement hazard. • Do not stand in the suction area of the Dryer Fan while it is operating. • Work alert after adequate rest. Never operate equipment if you are tired or distracted. (National occupational accident reports indicate that operators are typically getting tired and anxious to get work completed just before lunch, and between 3 pm and 5 pm when their energy reserves are depleted). Any worker who is tired and/or under pressure increases his/her chances of having an accident. Give extra breaks and/or varied jobs to all workers. • Never operate the Dryer if intoxicated or under the influence of alcohol or drugs. • Never work alone after all other personnel have left the site. You may find yourself injured and unable to reach help or a way out. MFH1956E 11 FIRE SAFETY BROCK® SUPERB® Low Profile Grain Dryers SQ Installation FIRE SAFETY In the event of a Dryer FIRE, act immediately! EMERGENCY PROCEDURES: ACT IMMEDIATELY if there are gas FUMES or unusual noises or vibrations. ACT IMMEDIATELY at the FIRST APPEARANCE of smoke or smolder. * In the event of a FIRE, CALL 9-1-1 IMMEDIATELY. Follow applicable procedures for such an emergency. Below: Take Step 1 or Step 2 FIRST, whichever Control you are closest to. Within a minimum 15 seconds between, shut off power at the other control: ONE. Press the RED EMERGENCY STOP Button on the red Control Panel to shut down the Dryer immediately. This stops the Fans to eliminate air supply to the fire. Remember: Doing this does NOT yet shut off the incoming power from the Electrical Power Cabinet to the Control Panel. TWO. Pull DOWN the Dryer DISCONNECT Handle on the inner door of the Dryer Disconnect Box. This shuts off electrical current to the Dryer Control Panel and trips the main breaker. Remember: Doing this does NOT yet shut off the Electrical Power Cabinet’s INCOMING power from the outside electrical Service Provider. THREE. Shut off power from the Provider’s incoming lines at the Service Disconnect so there is NO POWER AT ALL coming to the Dryer. It is important for all Operators to know the location of, and obey safety warnings regarding the power Service Provider’s Service Disconnect, sometimes in a building away from the Dryer. The Service Disconnect is provided by the Owner. Figure 6. Initial EMERGENCY Shutoffs FOUR. Shut off the fuel supply valve closest to the fire and at the Tank (if LP is used). Turn the Gas Hand Shutoff Valve at a 90degree angle to the Lower Plumbing Train to CLOSE. SQD Model shown; see Figure 8 for SQA. 12 MFH1956E BROCK® SUPERB® Low Profile Grain Dryers SQ Installation FIRE SAFETY FIRE SAFETY IMPORTANT! Locate the fire and determine: Can it be quickly contained / extinguished? Failure to quickly recognize the need for professional fire fighters could result in the loss of life, and will result in increased property loss. DANGER! There is toxic gas and smoke in the event of a fire. DO NOT ENTER the fire area or any enclosed space within the Dryer. Failure to follow this warning could lead to death or serious injury. To avoid becoming trapped above the fire, DO NOT CLIMB up to any area of the Dryer to attempt to put out the fire yourself! Starve the fire of oxygen by injecting it into the hot spot. Or blanket the grain from the top down. However, do not RELY on fire extinguishers to put out grain fires on this Dryer. A fire extinguisher may only be useful for small, containable fires near the pad. Figure 7. Dryer Fire If it becomes necessary to dump burning grain on the ground, open the Quick-Draw Slide Doors in the lower basket area for gravity dumping of the Dryer columns. However, do not dump grain until the fire department and water are available to extinguish burning embers that may come out. Stop all nearby equipment. Protect and move nearby equipment and other combustibles. Monitor the temperature in adjacent bins and structures. Check grain storage for any signs of hot embers that may have conveyed before Dryer shutdown occurred. MFH1956E IMPORTANT! Use water wisely: Hose down / cool propane tanks and grass surrounding the area. DO NOT spray water in the Dryer or adjacent grain bins. This could cause a “water gas” explosion with a CO-hydrogen gas mix, and/or swell the grain, (damage bin sidewalls). IMPORTANT! Always consult your local fire / emergency department for their recommendations given any emergency, and HAVE AN EMERGENCY PLAN IN PRACTICE for your facility. 13 FIRE SAFETY BROCK® SUPERB® Low Profile Grain Dryers SQ Installation FIRE SAFETY In the event of a Dryer FIRE, act immediately!

Dryer Disconnects Customer-Provided Service Disconnect (Example) Figure 12. Dryer Disconnect Box SAFETY Decals 18 MFH1956E BROCK® SUPERB® Low Profile Grain Dryers SQ Installation SAFETY Decals SAFETY Decals AC Drive Box IMPORTANT! DANGER! Locate and read your literature provided by the Vendor/Manufacturer of the AC Drive. An AC Drive must be grounded and can be extremely dangerous if all safety precautions are not observed. It is very important with an AC Drive to WAIT for capacitors to discharge stored electrical energy BEFORE any service is begun on the Drive. If a capacitor explodes, there will be a shotgun-like blast. The danger of a capacitor explosion is similar to that of an arc flash. WAIT at least fifteen (15) minutes for the energy to dissipate from the capacitors. VERIFY THAT NO VOLTAGE IS PRESENT before proceeding. Failure to observe this instruction will result in death or serious injury. WARNING Decal 1315-00247 is on the AC Drive Box Door. It reads, “WARNING! Keep door closed except for service.” See Figure 11. A bilingual DANGER Decal is visible inside the AC Drive glass door (some models). It reads, “DANGER! Hazardous voltage. Ground equipment. Before servicing, disconnect all power. Wait 15 minutes, then verify that no voltage is present. Close cover after servicing. Failure to follow these instructions will result in death or serious injury. Figure 13. AC Drive Box SAFETY Decals Control Box WARNING Decal (1315-00240) is located on the Control Box cover.

Qualified professionals and/or millwrights should be contacted prior to the installation to provide adequate electric power, gas and other components. Brock Grain Systems is not responsible for these installations. System Analysis Location of the Dryer from storage and driveways: a minimum of 4' [1.2 m] should be maintained between the Dryer and driveways or other structures. A minimum of 5' [1.52 m] should be maintained between the Dryer and nearest combustible structures. DANGER! Canadian Dryers The equipment shall be installed in accordance with the current installation codes for gasburning appliances and equipment, CAN1 B149.1 and B149.2, and/or applicable Provincial regulations, which should be carefully followed in all cases. Authorities having jurisdiction should be consulted before installations are made. All electrical wiring shall be done in accordance with the current CSA C22.1 Canadian Electrical Code, Part 1, and/or applicable provincial regulations as required. IMPORTANT! MFH1956E KEEP THE DRYER AWAY from power lines and live electric wires. Failure to follow this instruction will result in death or serious personal injury. The grain load can enter at the rear (standard) or front (Fan end). The Unload Auger may be standard (rear) or front (Fan end). If two Dryers are installed side-by-side, a minimum of 3' [.9 m] clearance is required between (U.S.) Canada: 5' [1.52 m] between is required. Figure 27. SQ Dryer Do not “box in” the Dryer amid tall structures. Allow passageways for air movement, such as beside a driveway. Plan for future expansion. Canada: Locate the Dryer a minimum of 50' [15.24 m] from any inhabited building. Handling: minimize handling distances and number of handling operations. Locate the Dryer close to an elevator leg for gravity unload, and close to an overhead hopper tank for gravity fill where practical. Drainage and Supply: Locate the Dryer pad, dump pit, and storage bins in a welldrained area, or provide an adequate tile drainage system. Keep hoses and pipes away from areas where equipment may drive over them. Power and gas suppliers: contact licensed contractors early to determine the best method and size of service for present and future requirements, and the need for reduced voltage starter. Future expansion: keep open the potential for changing Dryer sizes or adding additional drying units as your grain volume increases, both space and power-wise. Place the Dryer to take full advantage of future changes in handling equipment. Continuous flow Dryers may be a good option over in-bin drying when the yield exceeds 100,000 bu [3 524 m3] per year and where the climate is high-moisture or a short growing season (turnaround time must be short). 27 Planning the Installation BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Concrete Pad Foundation for the Dryer IMPORTANT! WARNING! The Dryer should be mounted on a level 5'' [12.7 cm] thick-reinforced concrete slab. Do not mount the Dryer on concrete blocks, which can be unstable. Failure to follow this instruction could result in death, serious injury, and or damage to the Dryer and other equipment. The concrete pad design is based on 3000 pounds psf [143.7 kPa] soil bearing capacity. For soils with lower capacity, consult the Brock Grain Systems Engineering department at the Frankfort, Indiana, location. See the Concrete Pad drawing below. Use these Figures to position the Dryer before it is installed. The Dryer must be properly anchored so it will not blow over in excessive winds. IMPORTANT! It is the responsibility of the Contractor, Installer, Owner and Operator to supplement the Dryer furnished by Brock Grain Systems with any necessary ELECTRICAL or STRUCTURAL items to make the Dryer installation comply with the National Electric Code, National Electric Safety Code, OSHA, and all other applicable federal, state and local laws and ordinances.

MFH1956E 29 Mechanical Installations BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Mechanical Installations Anchoring the Dryer IMPORTANT! To minimize damage from high winds, the Dryer must be firmly anchored to the foundation at or near each corner. Mount the Dryer on a 6'' [15.24 cm] thick reinforced concrete slab. Position and level the Dryer Basket Assembly to match load and unload conveyors, using two (2) 8 x 8 x 16'' [20.32 x 20.32 x 40.64 cm] concrete blocks at 16'' [406] elevation, spaced at approximately 48'' [1.22 m] center-to-center along the side frames. Place a reinforcing rod in each core and fill the cores with concrete. To provide crosswind stability, place blocks at the end of the base frame and place alternate sets of blocks at a 90-degree angle from the Dryer centerline. Anchor the Dryer Basket to steel anchors in the concrete pad by use of turnbuckles at or near each corner, or other suitable means. Leg Kit Assembly Brock offers optional Dryer Legs. Start at the rear end of the Dryer and locate a Leg set every 49'' [1 245 mm]. There must be a Leg also located in the four corners of the Fan Base where it attaches to the Basket. A Leg Kit Assembly (4128-2----; number changes with model and Leg height desired) is available for SQ8 through SQ40 Dryers. Installation shown here is the same for all sizes. Before installing the Leg Kit, remove the Bolt and Nut at both rear corners as shown in Figure 29. Leg attachment: Position each Leg Weldment (Item 1) with the flat side facing out, and the mounting tabs facing inward. The FRONT pair of Legs are set in the position shown (Item 9, Figure 30) under the Fan (all installations). The REAR pair of Legs is always in the position shown (Item 10) at 2.5'' [6.4 cm] from the back end of the Frame. Remaining Legs are set 49'' [124.5 cm] on centers from the rear.

Crossbrace Connection from Rear 32 MFH1956E BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Mechanical Installations Garner Bin Assembly For this operation, a 1/2'' impact with a 1 1/4'' impact socket works best. The Garner Bin is the wet grain holding bin at the top of the grain columns. It provides a surge, or working volume of wet grain so the Plenum air seal is not broken on Dryers with leveling augers that operate intermittently. The Garner Bin holds approximately 4.5 bushels per foot of Dryer length, providing 10 to 30 minutes’ drying volume (5 to 15 percent moisture removal). The Garner Bin can be folded down for shipping. REAR REAR CL CL LEFT RIGHT TOP VIEWS FRONT Figure 33. Standard Load/Unload: Garner Bin falls on LEFT IMPORTANT! FRONT Figure 34. Reverse Load: Garner Bin falls on RIGHT If more than one Lifting Rod (may also be called an Erection Screw) is used on the Dryer, two (2) impact wrenches are better. To avoid bending the Garner Bin, lift it as evenly as possible. Take your time and be safe. Lubricate the Garner Bin Lifting Rod (Detail B, Figure 35) prior to use. The Garner Bin can be lifted into assembly position with the provided Lifting Rod assembly. An impact or heavy-duty drill are best suited for driving the assembly. 1. Unbolt the Garner Bin from the top edge* (see Detail B) of all the shipping braces. This will require two (2) 1/2'' wrenches or sockets. There are times when the shipping brace will not release from the Garner Bin. Do not discard the hardware as it should be reinstalled when the lifting operation is completed. Apply a slight amount of upward pressure using the Lifting Rod. Locate the lifting mount which is attached to the Garner Bin. It should be on the same rib as the lift bolt. Remove the shipping brace, for access, (do not discard) and reinstall it when the lifting operation is complete. The bolt used to attach the Lifting Rod to the lift bracket is a 3/8'' Bolt with a self-locking Nut. 2. Rotate the Garner Bin Lifting Rod into position. Secure the lifting brackets together with the 3/8'' Lock Nut and 3/8'' Bolt. Finger-tighten snugly. 3. Lift the Garner Bin into position by turning the Lifting Rod clockwise. For Dryers with more than one Lifting Rod, make sure that the Garner Bin rises fairly level. For best results, alternate between Lifting Rod assemblies, raising 5'' or 6'' [12.7 or 15.2 cm] at a time at each location. Lift until the skin flanges are in alignment with the holes in the gussets on the Upper Basket on the opposite side of the Lifting Rod. As you install the Lifting Rod to the bracket, be sure the pivot bolt is not too tight. The Lifting Rod must be allowed to pivot freely.

Garner Bin Components Detail A: Lifting Rod IMPORTANT! IMPORTANT! 34 4. To install the galvanized End Panels (approx. 21'' x 27''): Remove the lower 5/16'' x 3/4'' Bolts on each end of the Garner Bin near the upper triangular bulkhead. These End Panels are to be installed on the outside of the upper triangular bulkhead and the upper galvanized bulkhead using 5/16 x 3/4'' Self-tapping Screws along the top, sides, and inner four (4) holes along the bottom edge. Leave all these fasteners loose until the 5/16'' x 3/4'' Bolts and Nuts can be installed in the outer four holes above the Garner Bin Pivot Bolts (at the galvanized upper bulkhead). Tighten completely. If the Dryer is set for REVERSE load, the Garner Bin will fall on the RIGHT side of the Dryer. 5. Install the 5/16 x 3/4'' Whiz Lock Bolts connecting the gussets to the Garner Bin (both sides) and into the open hole in the skin flanges. 6. The Top Grain Level Switch Assembly is located at the end OPPOSITE the fill end of the Garner Bin. Check the Paddle for free rotation.

On the opening over the load Auger, install the Fill Hopper Assembly with 1/4 x 1/2'' Sheet Metal Screws to the opposite end of the Garner Bin. It can be located at either end of the Dryer. The Fill Hopper Control Slide Plate is an inclined slide plate that is adjusted to provide a grain feed opening adequate for the volume being conveyed, while keeping the grain column weight from loading down the end of the auger. It maintains a seal in gravity systems and keeps the auger from throwing grain out of the Hopper on both conveyor and gravity-filled systems. Install the Slide Gate and Lid.

To counter this on the SQ Dryer models and earlier SD dryers supplied with the drag unload option, a special panel has been developed. This panel, when placed in the discharge box, can split the grain flow being presented to the air system, evening out the fill process. IMPORTANT! The Unload Trough Floor Extension Panel (5644-00078) is included in items shipped loose in all SQ models. It is used ONLY on Dryers that are attached to an AIR SYSTEM. If your Dryer Discharge is readily accessible: 1.Remove one of the Discharge Side Panels completely. See Figure 52. 2.Loosen the eight (8) screws holding the opposite Side Panel. 3.Slide the Extension Panel through the side of the Discharge that is open, making sure the tab on the opposite end of the Extension goes between the third and fourth Screws down the side of the Side Panel still attached. The large corner notches must point away from the Dryer basket. 1 Item Part No. Description Drag 1 5644-00068 Discharge-SA Unload 2 Discharge Side Panel Extension3 5644-00078 Panel, Trough (Bottom) 1/4''-20 Self-Tapping 4 Screws (existing) 3 2 4 Figure 52.

Unload Sensor and Trip Lever MFH1956E 49 Plumbing Train Connections BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Plumbing Train Connections Proper Fuel Line Connection is Critical DANGER! DEALERS and INSTALLERS DANGER! IMPORTANT! It is of utmost importance that care be taken by the Dealer and Installer to match the type of FUEL noted on the Fuel Warning Plate. Starting the Dryer one time on the wrong fuel can produce a firestream tens of feet in length, that can destroy many Dryer components and possibly the entire Dryer. Failure to follow specific instructions on Fuel WARNING Plates and tags could result in fire, explosion, equipment damage, death or personal injury. Installation and filling of liquefied propane (LP) gas storage and transfer systems must conform with National Fire Protection Association Standard: Storage and Handling of Liquefied Petroleum Gases, NFPA No. 58, (current edition in effect at the time of the installation). Installation and/or service must be done only by licensed gas contractors conforming to national and local applicable codes. Failure to follow these requirements will result in death, serious injury, or equipment damage. Connect the Plumbing lines only to fuel lines specified. A Fuel WARNING Plate (5537-00049 or 5537-00050) is located on or near the connection hose or pipe. See below. See also Figures 5 and 6. Review specific approved Fuels on Pages 55-59 and Pages 75-76. Figure 56. Fuel Warning Plate (LP Only) 5537-00050 Figure 57. Fuel Warning Plate (Nat Gas) 5537-00049 LP Dryers must have one SHUTOFF VALVE at each tank, and should have another valve within 5' - 25' [1 524 - 7 620] of the Dryer. All valves must be easily accessible. Natural-gas Dryers must have a MANUAL SHUTOFF VALVE installed in the supply line at least 25’ [7 620] from the Dryer and easily accessible. All Dryers must have a proper EXCESS FLOW valve —in the LP fuel line at the tank—sized according to fuel line size. Combo Dryers Combo Dryers are shipped with LP Orifices installed. Burner Orifices need to changed when switching fuel types. Natural Orifices are shipped loose with Combo Dryers. Before Initial Startup Check the complete plumbing system for leaks or tightness of fittings, especially at unions. Use a liquid soap solution with the plumbing train under normal operating pressure. Purge new plumbing lines before final assembly to blow oil, dirt, and thread chips out of the lines that could interfere with proper operation and damage plumbing components. 50 MFH1956E BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Plumbing Train Connections Plumbing Train Components Emergency Hand Shutoff Valves IMPORTANT! All Hand Valves on liquid lines should be opened very slowly to allow the downstream line pressure to build up and equalize with the tank pressure. This eliminates “flashing” of the liquid to a vapor, which is accompanied by a large temperature drop in the partial-vapor, partial-liquid mixture. Emergency Hand Shutoff Valve / “Inlet Hand Valve”: located where the fuel line enters the Dryer on the lower bulkhead. See Figure 58. See also Figures 5 and 6. This quick-action, manual Shutoff Valve located near the Inlet connection on both LP and natural gas plumbing trains. This Valve is located upstream of the Strainer to facilitate Strainer cleaning without shutting off the tank and draining the line. The Inlet Valve(s) should be turned off any time the Dryer is not operating. The Hand Valve needs to be OFF and gas bled out of the Plumbing Train before removing the Strainer. Additional Hand Valves are located on the Upper Plumbing Train on top of the Dryer. See Figures 61 and 62. Pilot Hand Valve: The quick-action, manual Shutoff Valve in the pilot plumbing train, used for service on the pilot plumbing assembly. Burner Hand Valve: The quick-action, manual Shutoff Valve in the main Burner plumbing train, downstream of the Primary Regulator and other valves. It is used for test-firing and service work on the Burner assembly. Hydrostatic Relief Valves: Pressure safety-relief valves are pre-set to 300 psi [2 068.4 kPa]. These protect piping from “ram,” “liquid hammer,” or surge effects that occur when valves suddenly close, instantly stopping an incompressible liquid flow. Liquid propane “flashes” (from a complete liquid to a partial vapor state) after leaving the tank and passing through a restriction (such as Strainer and Inlet Hand Valve), so it is somewhat compressible.

Gas Shutoff Hand Valve and Fuel Connection Plate MFH1956E 51 Plumbing Train Connections BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Upper Plumbing Train Gauges are located on the Upper Plumbing on top of the Dryer. See Figures 61-62. Inlet Pressure Gauge: This Gauge near the fuel inlet connection point (on either LP or natural gas) gives the supply line pressure at the inlet for service and operating reference. It is used to evaluate the fuel supply adequacy or possible line restrictions. Burner Pressure Gauge: The pressure on the Burner manifold pipe, downstream of all controls, which measures Burner gas pressure (LP or NAT). There is no “correct” setting for this. The pressure will vary until the proper air drying temperature is established. Figure 59. Plenum Static Air Pressure Line Modulating Motor and Butterfly Valve The Modulating Motor is a self-contained device with a transformer for stepping down 120V Control Voltage to 24V to power the motor. It is controlled by a set of contact closure signals from the I/O Panel (discussed in the Controller Installation Manual). The Modulating Motor develops 150 in-lb. of torque and rotates 160 degrees to open and close a butterfly Modulating Valve through a linkage system that prevents the Modulating Valve from rotating beyond the maximum of 90 degrees full open rotation. The Valve linkage has been factoryadjusted so that the valve is closed when the Motor is in its full counterclockwise position, which will be the case any time the burner is turned OFF. The Modulating Valve is a butterfly-type control valve, which is moved by linkage from the Modulating Motor. Should the Modulating Motor or Valve be replaced, the linkage should be set in accordance with Figure 60 at right. As a temporary measure, the Burner can be manually adjusted in the event of a defective Modulating Motor by removing the linkage arm and running the Modulating Valve by hand and manually setting fuel flow to the Burner.

LP tanks with a combined volume of 2001 - 30,000 gallons [7 575 - 11 362 L] capacity must be installed with the nearest point at least 50' [15.24 m] or more from the nearest point of the Dryer. This is mandatory per NFPA Bulletin No. 58, Storage and Handling Liquefied Petroleum Gases. IMPORTANT! LP piping must be Schedule 80 black iron pipe or stronger, connected to the supply line on LP-gas Dryers. Each LP gas supply tank must have an excess flow valve that has a rated flow less than the flow capacity of the piping from the tank to the Dryer. The piping and excess flow valve design must be installed inside each LP tank and must meet the requirements of NFPA No. 58, Paragraph 3135 (a) (3) current edition in effect at the time of installation. Suggested excess flow valve capacity ratings are 3 - 6 gallons [11.4 - 22.7 L] per minute. A manual gas shutoff valve must be installed as close to the LP tank as possible, must be at least 25' [7.62 m] away from the Dryer, and readily accessible. Each tank must have a separate shutoff valve. For manifolds connecting parallel tank installations, a main shutoff valve should be installed in the pipe just downstream of the manifold. MFH1956E IMPORTANT! DO NOT OPERATE the Dryer while the LP tank is being filled—wait for ten minutes after the truck filler hose has been removed. Refer to the Owner/Operator Manual MFH1932 for recommended tank capacity for desired hours of use. DANGER! DO NOT use tanks for liquid propane (LP) that have been used for ANHYDROUS ammonia! This includes previously purged tanks that have been used for anhydrous. Dryer gas train components may be damaged, causing a Dryer malfunction which could lead to serious safety hazards and/or fire. Installing any tank (for an LP fuel supply to the Dryer) which has previously been used for anhydrous ammonia poses a safety threat. Brock Grain Systems will not be held liable for any purging and cleaning methods used for such tanks. If such a tank is used, this will void the Dryer Warranty. 55 Plumbing Train Connections BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Upper Plumbing Train for LP (Top of Dryer) Hydrostatic Relief Valves (Item 3): Pressure safety-relief valves are pre-set to 300 psi [2 068.4 kPa]. These protect piping from “ram,” “liquid hammer,” or surge effects that occur when valves suddenly close, instantly stopping an incompressible liquid flow. Liquid propane “flashes” (from a complete liquid to a partialvapor state) after leaving the tank and passing through a restriction (such as the Strainer and Inlet Hand Valve), so it is somewhat compressible. Modulating Motor (Item 10) is located on the plumbing train and is an electric motor powered from a 120V - 24v transformer. The Motor receives an OPEN or CLOSE command from the Temperature Control. With this signal the Modulating Motor drives the Modulating Valve (more opened or closed) to maintain desired drying air temperature. The Butterfly Valve (Item 11) rotates approximately 90 degrees from full-closed to full-open, to vary the inches of water-column pressure to the Burner. The Modulating Motor and Valve are connected with adjustable linkage. 7 3 4 8 26 6 7 2 8 5 3 LP INLET VA TO Main Solenoid Valve (Item 4): opened and closed by an electrical-powered solenoid and capable of handling liquid propane.

IMPORTANT! Installation of natural gas transfer systems must conform with National Fire Protection Association Standard: Natural Fuel Gas Code, NFPA No. 54, (or current edition in effect at the time of the installation). Installation and/or service must be done only by licensed gas contractors conforming to national and local applicable codes. Failure to follow these requirements will result in death, serious injury, or equipment damage. Natural Gas piping must be Schedule 40 black iron pipe or stronger, connected to the fitting on natural gas Dryers. For proper operation, at least 8 psi [55.2 kPa] must be supplied. Use maximum line size when natural gas pressure is 8-10 psi [55.2 - 68.9 kPa]. Table values apply on natural gas downstream of the gas company meter and Regulator only. Contact the gas company for greater equivalent lengths than shown in the Chart. If available natural gas pressure is higher than 20 psi [137.9 kPa], a primary Regulator must be provided to reduce the Dryer inlet pressure to 10-20 psi [68.9 - 137.9 kPa].

IMPORTANT! DANGER! Electricity can KILL! Use extreme CAUTION around electrical components of this Dryer. Installations MUST be done by a certified/ licensed electrician, in accordance with all national, state and local electrical SAFETY codes listed at right. Failure to follow these instructions will result in death or serious injury. DANGER! Locate Your ELECTRICAL SCHEMATIC DIAGRAMS: They represent the control wiring circuit, also known as a ladder-type diagram. The Schematic clearly shows how the various controls are interlocked and allows a qualified electrician to quickly troubleshoot electrical problems or malfunctions. These are found at the end of this Manual, the Owner/Operator Manual MFH1932, and Controller Installation Manuals MFH1977 and MFH1978. Dryer installations and all components SHALL MEET the National Fire Protection Association Standard 61B (for the prevention of fires and explosions in grain elevators and facilities handling bulk raw agricultural commodities) and Standard 70, as well as the National Electric Safety Code, American National Standard Inst. ANSI-C1, and all other applicable state and local requirements. Brock Grain Systems neither assumes responsibility for the electrical wiring used with this Dryer, nor will be liable for damage to the Dryer because of improper electrical installation or use. Improper installation or use will void the Warranty. Your SUPERB® Dryer is completely factory pre-wired. Locate the Wiring Diagrams in your project packet. After proper installation, keep them in a handy place for future reference in case of the need for service. On both single-phase and three-phase models, power wires connect to the lugs at the top of the Dryer Disconnect Circuit Breaker. Dryers are normally wired for 230-volt single-phase or 230 / 460-volt three-phase power. However, 208V, 380V, 415V, or 575V three-phase models are also available. SAFETY requirements Contact your power provider before installation. They can determine if any adjustments in their lines will be necessary to accommodate the increase in load the Dryer will make on the current wiring. Adequate electrical service must be supplied. The main power transformer must be sized to handle maximum Dryerconnected horsepower (see Electrical Specifications Table, Page 74), plus all other auxiliary conveyor and grain center Motors that operate simultaneously. Low voltage may cause Motor and Control damage, voiding the Manufacturer’s Warranty. Do not jeopardize your SAFETY or your BROCK® Dryer Warranty with improper electrical installation. Your Installer should have your electric company check the transformer and lead wires. Be sure the wires are of an adequate gauge to carry the load of your Dryer Motors, including starting and full load operating conditions. Failure to follow these instructions will result in death or serious injury. IMPORTANT! It is the RESPONSIBILITY of the Contractor, Installer, Owner and Operator to supplement the Dryer furnished by Brock Grain Systems with any necessary ELECTRICAL or STRUCTURAL items to make the Dryer installation comply with the above codes. IMPORTANT! Review and always follow the “Electrical Connection/Disconnection Procedures for Dryer Testing” (Page 72), and the “Manufacturer’s Recommended Minimum Lockout/Tagout Energy Control Procedures” (Pages 77-78) in this Manual. Lockout SAFETY Switches IMPORTANT! A LOCKOUT device/lockable disconnect switch must be installed on Dryer Control enclosures containing hazardous voltage wiring. IMPORTANT! To prevent a hazardous condition, all SAFETY devices, including wiring of electrical devices shall be arranged to operate in a “FAIL-SAFE” manner. That is, if a power failure or failure of the device occurs, a HAZARDOUS CONDITION will not result. To prevent a hazardous condition, the machine and all associated equipment MUST be PREVENTED FROM RESTARTING on its own after a power failure when power returns or a jam is cleared. A MANUAL re-start is required. Do not install or use any method to start or restart the Dryer which bypasses factoryinstalled SAFETY features. IMPORTANT! 60 To guard against electrical shock, all Dryers shall have a GROUND connection. MFH1956E BROCK® SUPERB® Low Profile Grain Dryers SQ Installation IMPORTANT! Electrical Installations Review and always follow the “Electrical Connection/Disconnection Procedures for Dryer Testing” (Page 72), and the “Manufacturer’s Recommended Minimum Lockout/Tagout Energy Control Procedures” (Pages 77-78) in this Manual. The AC Drive Box IMPORTANT! DANGER! Electricity can KILL! Use extreme CAUTION around electrical components of this Dryer. Installations MUST be done by a certified/ licensed electrician, in accordance with all national, state and local electrical SAFETY codes listed at right. Failure to follow these instructions will result in death or serious injury. The AC Drive Box must be grounded. Locate and read your literature provided by the Vendor/Manufacturer of the AC Drive. An AC Drive must be grounded and can be extremely dangerous if all safety precautions are not observed. It is very important with an AC Drive to WAIT for capacitors to discharge stored electrical energy BEFORE any service is begun on the Drive. If a capacitor explodes, there will be a shotgun-like blast. The danger of a capacitor explosion is similar to that of an arc flash. WAIT at least fifteen (15) minutes for the energy to dissipate from the capacitors. VERIFY THAT NO VOLTAGE IS PRESENT before proceeding. Failure to observe this instruction will result in death or serious injury. A solid copper ground wire is shipped coiled from the bottom of the Control Panel Box. A copper Equipment Ground Rod 5/8'' dia. x 10' [3 048] is shipped loose. Weatherproof all outdoor outlets and fittings that are exposed to wind, rain and snow. Avoid using electrical equipment outdoors in wet conditions. Use a ground fault circuit interrupter (GFCI) wherever water and electricity may come into contact with each other. When a GFCI senses current leakage in an electrical circuit, it assumes a ground fault has occurred and interrupts the power, helping to prevent serious injury from electrical shock. Dryer/Equipment Disconnect Box The Dryer Disconnect is on the front of Dryers with centrifugal Fans. • The Dryer Disconnect and the Dryer unit should be grounded. See the Electrical Specifications Chart on Page 74 for Dryer amperage to properly size components. See additional SAFETY Decal information on Page 18. • After connecting power and turning on the Dryer Disconnect, the “POWER ON” light should be on, if that option is present. Figure 67. Circuit Breaker in Dryer Disconnect MFH1956E 61 Electrical Installations BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Control Box CAUTION! IMPORTANT! Service and program the computer component properly. Failure to properly service this computer component according to its specific Manual could damage the equipment and void the Warranty. The Dryer must be completely installed with auxiliary equipment ready to run BEFORE either Controller system can be tested or will work properly. With the exception of a CONVERSION to the BROCK® QUANTUM® Controller specifically designed for use with the BROCK® SUPERB® Dryer, installing a non-BROCK® (another manufacturer’s) Controller or any other type Controller on a BROCK® SUPERB® Dryer WILL VOID THE WARRANTY on the BROCK® SUPERB® Dryer.

WARNING! IMPORTANT! This Grain Dryer can operate auxiliary load and unload conveying equipment automatically. Any auxiliary equipment wired into the Dryer’s control circuit can be started automatically by the Dryer at any time. Stand clear of all auxiliary equipment drives, moving parts and discharges any time the Dryer is in operation. Disconnect all power to the Dryer and auxiliary equipment before servicing. Failure to observe these safety precautions can result in death or serious injury. Read “Auxiliary Starter Control Connection.” Review and follow the “Electrical Connection/Disconnection Procedures for Dryer Testing” below, OSHA Lockout/Tagout regulation 1910.33(b)(2) through 1910.333(c)(2), and the “Manufacturer’s Recommended Minimum Lockout/Tagout Energy Control Procedures” (Pages 77-78) in this Manual. 1. Read “Auxiliary Starter Control Connection” in the following section before wiring auxiliary Load and Unload Conveyors (Augers). You will need wiring drawing Part No. 3724-00052 (as shown in Figure 73) for the AC Drive. It is located in the back of this Manual and the Controller Manual: Figure 73. 11'' x 17'' [279 x 432] Schematic 3724-00052 (AC Drive Wiring) 2. If the Dryer is equipped with a factory-installed auxiliary Starter Unit, check for proper Motor voltage and horsepower ratings. Connect the Auxiliary Motor wires directly to the connect overload relay block below the contactor. In all cases, a separate auxiliary Starter Disconnect will be factory-mounted beside the Main Dryer Disconnect, and will tap into the service feeder wires powering the main Disconnect. If magnetic starters for Auxiliary Conveyors are supplied by the customer, the power wiring to the starters must be supplied from outside the Dryer to an auxiliary disconnect circuit breaker. 3. Terminal sets 66-67 and 68-69 can provide only switching action, not power, for auxiliary load and Unload Motor starter coils, respectively. (U.S. only) 115-volt control power (Auxiliary Starter Control Connection, Method I, see Pages 6566) may be supplied from an external source or from the terminal strip to the terminal contacts; the voltage depends on the individual starter coil rating. If an external power source is used, install a tag or decal on the Control Panel stating that “This Panel has more than one source of power.” 5. Auxiliary conveyors must be installed so that they are not supported by the Dryer. 6. Install the Load Hopper so that the Slide Adjustment Bolt is on the side of the hopper away from the Dryer. 7. Auxiliary conveyor capacity for loading and unloading should be sized to meet maximum Dryer handling requirements if feasible. For pneumatic conveyors, the recommended rated capacity is closer to the Dryer rated capacity to keep system costs reduced. 64 MFH1956E BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Electrical Installations 8.When gravity bins are used, adjust the grain hopper Slide to regulate flow and eliminate Motor overload. Grain flow should be set so that the Load Motor amperage goes no higher than full-load amperage. The highest Motor load occurs at the end of the cycle. Auxiliary Starter Control Connection DANGER! Since this Dryer can operate auxiliary Load and Unload conveying equipment automatically, it is IMPERATIVE that the Owner/Operator warn all operators, service personnel, employees and family members about the hazards involved when working near automatic equipment. Failure to do so could cause death or severe injury. Factory-Installed Auxiliary Starter Units: Dryers ordered with the optional auxiliary starter unit have been wired at the factory. Verify that Motor sizes to be used match the sizes labeled on the starters within the auxiliary starter enclosure. You will need wiring drawing Part No. 3724-00016A for Auxiliary Motor Starter wiring information. See Figure 74. IMPORTANT! Different circuit breakers, contractors, and/or overload relays may be needed if sizes do not match. Connect the auxiliary Motor power wires directly to the correct overload relay block below the Starter. Start the Motors and check for correct rotation. Single-phase Motors must be rewired at the Motor junction box to change rotation. Three-phase Motors can be reversed by exchanging any two (2) of the three (3) Motor power wires. Field-Installed Auxiliary Conveyor Starters Consult a SUPERB® serviceman or a qualified electrician in selecting the correct Motor Starter for auxiliary conveyors. For automatic sequencing with the Dryer, auxiliary conveyor starters supplied by the customer should be wired according to Schematic 3724-00016A in the back of this Manual and the SQ Dryer Owner/Operator Manual MFH1932. Figure 74. 115V Auxiliary Starter Coils, Single- and Three-Phase Schematic 3724-00016A 1. Typical example of 115V auxiliary starter control circuit with overload relay interlock for one auxiliary load motor (M3) and two auxiliary Unload Motors (M1 and M2). Load Auger Motor starter auxiliary contact wire terminals 66 and 67, and unload auger motor starter auxiliary contact wire terminals 68 and 69, provide switching action, not power, for the auxiliary motor starter coils. 115V coil power may be supplied from an external source or from the Dryer terminal strip to terminal contacts. IMPORTANT! MFH1956E A tag or decal should be placed on the Control Panel stating that “This Panel has more than one source of power.” 65 Electrical Installations BROCK® SUPERB® Low Profile Grain Dryers SQ Installation BASO Flame Sensor Switch and Thermocouple The BASO thermocouple sensor is mounted in an adjustable sleeve at the end of the Burner pilot baffle plate with its tip extending into the pilot flame. The other end of the thermocouple is connected to the BASO Switch inside the Burner Ignition Transformer Box. In operation, the thermocouple is heated and sends a millivolt (mv) signal to the BASO Switch which activates an internal relay. To see the thermocouple signal strength, a millivolt meter is supplied with one lead grounded to the BASO SW and the other lead connected to a terminal inside the BASO Switch just opposite the thermocouple attachment point (the thermocouple must be connected to the BASO Switch). An unheated thermocouple will have an output signal of 0mv. As the thermocouple is heated, the BASO Switch relay should activate at approximately 9mv and drop out at 2-3mv. (The meter needle should “jump” when the internal relay switches.) The desired output range is 18-21mv. A lower signal causes marginal operation; a higher signal reduces the life of the thermocouple. The thermocouple can be observed through the Plenum Access Door at the rear of the Dryer. In the desired range of 18-21mv, the tip of the thermocouple should have a dull red glow. If no color is visible, the mv signal is usually low (below 18mv). If a bright red color is observed, the mv signal is usually high (23-27mv). If the thermocouple signal needs to be adjusted, use the millivolt meter. If the meter signal is low (such as 1-13mv) or no color change is observed, follow these steps to increase the signal: (1) Check the BASO thermocouple for a loose connection at the BASO Switch junction, (2) Move the thermocouple tip in the burner pilot baffle sleeve farther into the flame and tighten the lock collar set screw, or (3) adjust the pilot regulator to heat the thermocouple more (if increasing the gas pressure doesn’t increase signal, try decreasing the pressure). For a high signal or a “bright or cherry red” tip: (1) Reduce the amount of thermocouple exposure or (2) Adjust the pilot flame length with the pilot regulator to change the color to a “dull red” and/or the signal to 18-21 millivolts. If the millivolt reading (and color) are close to the “ideal” range of 18-21 millivolts, turn on the main burner and observe the thermocouple conditions. The full burner flame compresses the pilot flame and sometimes changes the thermocouple signal to a desirable level. If no signal or a low signal is observed under all adjustment conditions, the thermocouple is probably weak and should be replaced. 66 MFH1956E BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Electrical Installations Flame Relay Flame Sensor Switch is also called the BASO, located in the Burner Ignition Transformer Box next to the Burner Access Door on the top of the Dryer. A BASO flame switch with a BASO thermocouple serves as the pilot flame sensor. The BASO Switch normally closes within 10-20 seconds after the pilot flame is established, energizing the Flame Relay. If the pilot flame goes out or weakens (to the point the thermocouple signal is inadequate), the BASO will open, instantly de-energizing the Flame Relay. Control wiring for the SPECTRUM®/QUANTUM® Flame Relay is found on 11'' x 17'' [279 x 432] Schematic diagram 3724-00081, located in the back of the QUANTUM® Controller Manual Supplement, MFH1978; the SPECTRUM® Controller Manual Supplement, MFH1977; and the SQ Owner/Operator Manual MFH1932.

To reverse a three-phase motor, switch any two of the three power leads. If all Motors have the wrong rotation, exchange the two (2) outer leads (L1 and L3) in the Dryer Disconnect Switch. Figure 77. Proper Fan Rotation (arrow direction) Check Motor Rotation IMPORTANT! Pay attention to ROTATION Decals (1315-00038) on the Dryer housing. Do not reverse Motor directions until all Motors are checked. Check rotation of Motors before loading the Dryer and starting the drying operation. • Turn the Main Disconnect ON. • Check the Load Auger for clockwise rotation (looking at the Auger sheave) and for correct rotation of auxiliary loading conveyors (load Auger sheave should turn counterclockwise if the Dryer loads on the Fan end). If two or three Motors have wrong rotations, switch two power leads in the Dryer Disconnect. If only the Fan Motor is reversed, switch two of the leads at the Fan Motor Starter in the Control Panel.

MFH1956E 69 SAFETY System Checkout BROCK® SUPERB® Low Profile Grain Dryers SQ Installation \ SAFETY System Checkout Your SUPERB® Dryer has many SAFETY controls interlocked to stop the Dryer if a hazardous condition develops. The following controls stop all Dryer functions immediately and necessitate a manual restart of the Dryer. Your Dryer installation (including Plumbing Train Connections on Pages 50 - 59) should not be considered complete until a SAFETY Systems checkout is run to see that all SAFETY systems are in working order. This should be done before initial startup. It should also be done at the beginning of each season and any components replaced if necessary. Red Power Light (optional) Turn the Dryer Disconnect Circuit Breaker ON. Observe the red light on the front of the Control Cabinet. Fuel Line Shutoff Valves (optional) 1. Individually test for complete closure of each shutoff Valve between the Dryer and LP gas tank or natural gas meter. 2. Start the Fan and Burner. 3. Close each Valve separately and observe if the fuel supply is definitely cut off to the Dryer by each Valve. Vent Pipe Outlets 1. Inspect all Hydrostatic Relief Valves (LP gas Dryers). 2. Make sure outlets are unobstructed, covered with the rubber rain cap, and pointed in a direction away from the Dryer (or any other Dryer, Fan Motor, work platform, office, etc.).

Unload Sensor and Trip Lever MFH1956E 71 Pre-Startup Electrical Testing and Inspection BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Pre-Startup Electrical Testing and Inspection Pre-Startup Electrical Testing Is Required! DANGER! Electricity can kill! Startup inspections MUST be done with the MAIN POWER LOCKED OUT and TAGGED OUT. Failure to follow these instructions will result in serious injury or death. IMPORTANT! With MAIN POWER LOCKED OUT and TAGGED OUT, and with NO VOLTAGE detected, inspect electrical controls and wire connections for tightness. Make sure your fuel supply is adequate. Be sure the initial SAFETY Systems Checkout has been done. Review and follow the “Electrical Connection/Disconnection Procedures for Dryer Testing” below, OSHA Lockout/Tagout regulation 1910.33(b)(2) through 1910.333(c)(2), and the “Manufacturer’s Recommended Minimum Lockout/Tagout Energy Control Procedures” (Pages 77-78) in this Manual. Electrical Connection/Disconnection Procedures for Dryer testing WARNING! IMPORTANT! Pre-Startup electrical testing is REQUIRED. The procedures outlined on this page provide minimum instructions to be followed by the Qualified Electrical personnel performing Startup on this Dryer. Any additional applicable laws, regulations, and codes that may apply to such procedures MUST be followed. Inclusion of these procedures in this Manual does NOT in any way imply that these procedures can be used BY unqualified personnel or in substitution FOR Qualified Electrical Personnel. 72 These procedures MUST be followed by Installers of BROCK® Dryers and related equipment. Failure to follow these procedures could result in death or serious injury, and an unsafe situation. Connecting Procedures: 1. BEFORE ANY TESTING, make certain all Service Disconnects are in the OFF position and LOCKOUTS/TAGOUTS are in place!!!! 2. Verify that the Disconnect to the Dryer being tested is in the OFF position. 3. Verify proper voltage to be used: 240V single-phase, 208V, 240V, 380V, 480V or 575V three-phase. 4. Verify that your voltage tester is operating properly: Test it on a known live voltage source to verify that the tester is working properly before testing the power source to the Dryer. 5. Check for voltage at the Dryer Disconnect. NO VOLTAGE should be present! 6. Before powering up, a 10' [3 048] area around the open panel to be “energized” will need to be blocked off with a non-conductive perimeter guard. Only properly protected and trained personnel can enter this area when the open panel is energized. 7. You may now TURN ON the Service Disconnect (wherever it is located for your facility, usually in a building away from the Dryer), and then turn on the Dryer Disconnect (the lever/handle on the inside door of the Dryer Disconnect) to perform all required tests. Disconnecting Procedures: 1. Turn OFF the Dryer Motor or Motors, and then turn off the Dryer Disconnect. Refer to the photos on Pages 18 and 61. 2. Turn OFF, LOCKOUT and TAGOUT the Service Disconnect (wherever it is located for your facility). 3. a. If the purpose of the disconnection is to POWER DOWN while not in use: After the power is locked/tagged OUT, check that all is clear. Then push the START switch to confirm that the unit will not start, as instructed in the Manufacturer’s Lockout/Tagout procedures (Pages 77-78). b. If the purpose of the disconnection is to WORK on the electrical controls, a qualified electrician with proper PPE should perform these tests, after following LOCKOUT/TAGOUT (LOTO) Procedures (Pages 77-78). The qualified electrician must: Verify that the voltage meter being used is working properly (i.e., with a fully charged battery source that will give an accurate reading). Test the voltage meter on a known voltage source, and then confirm after Locking/Tagging out the power source, so there is no voltage present. 4. All Disconnects MUST ALWAYS REMAIN IN THE "OFF" POSITION, LOCKED OUT and TAGGED OUT when not in use! MFH1956E BROCK® SUPERB® Low Profile Grain Dryers SQ Installation Pre-Startup Electrical Testing and Inspection Checkout and Adjustments 1. Make sure all removable Doors, Guards and Covers are in place. 2. Be sure the Unload area is clean and Covers are secured. CAUTION! Do not step on and/or bend the perforated inner grain panel sheets when the Dryer is empty. 3. Fill Hopper Control Gate: Initially set to 3'' - 5'' [7.6 - 12.7 cm] clearance at the intake side. Final Gate clearance should be set while filling, so grain covers the lower edges of the Plate to provide a seal to keep dust and fines from blowing out. 4. Wet and Dry Auxiliary Conveyors: Check that they are correctly oriented and operational. 5. Modulating Valve: Check that linkage is tight and in alignment. 6. The manual Shutoff Valve located near the Inlet connection on both LP and Natural Gas plumbing trains. The Inlet Gas Valve(s) should be turned OFF any time the Dryer is not operating. U.S. only: If the Dryer is equipped with the dual LP-NAT plumbing option, make sure proper orifices are installed per gas type. After verifying both Inlet Gas Valves are closed, open the manual Inlet Gas Valve for the desired fuel. 7. Service Light: To keep electrical control circuit components warm, turn on at least one hour prior to daily startup (or leave on overnight) if the outside temperature is below 32 degrees F. Do not use this light in the daytime if the temperature is above freezing (32 degrees F). CAUTION! Failure to follow the following directions may result in an unsafe situation. 8. If the Dryer is wired for three-phase power, check the control circuit voltage before starting the Dryer, to verify that it is within a 110V to 125V range. Follow instructions on the bilingual Circuit Breaker Card shown below (5542-00001, ships loose): • Install the card with the circuit breakers facing toward the I/O Panel. make sure that the fuse is installed and that it is rated at 6 amps. • Make sure that the connector on the circuit breaker is lined up with the male end on the I/O Panel. • Firmly press the card straight into the connector until it is secure and in place. Failure to press the card straight may cause the male connector to break on the board. Figure 83. Circuit Breaker Card 9. Check rotation of Motors. See Page 68. 10. With the fuel in the Plumbing Train under pressure, check all fittings for leaks with a liquid soap solution, especially at unions.

Any more stringent, current, or up-to-date requirements pursuant to OSHA or other regulations must be followed to the extent applicable. Manufacturer's Recommended Minimum Lockout/Tagout Energy Control Procedures Purpose The procedures listed herein are intended to provide minimum instructions to operators and/or end users of products supplied by the Manufacturer. To the extent that applicable laws, regulations, and/or codes, (such as, without limitation, OSHA regulations and requirements), provide more stringent requirements, all erectors, installers, operators and/or end users of the products referenced in this manufacturer’s product manual, such applicable laws, regulations and/or codes MUST be followed. Whenever maintenance or servicing is completed to machines or equipment, all such maintenance and servicing shall be completed in accordance with the requirements of OSHA's 1910.147, et seq., including any amendments thereto. Such requirements are designed to ensure that the machine or equipment is stopped, isolated from all potentially hazardous energy sources and locked out before employees or operators perform any maintenance or servicing where the unexpected energization or start-up of the machine or equipment or release of stored energy could cause injury. Authorized and Affected Individuals Authorized operators and individuals who must be trained on these procedures include, without limitation, individuals who must lock out or tag out machines or equipment in order to perform servicing or maintenance on that machine or equipment. Affected individuals who must follow these procedures and be trained on the minimum requirements stated herein include individuals whose job responsibilities or operational responsibilities require him/ her to operate or use a machine or equipment on which servicing or maintenance may be performed, or whose job responsibilities or operational responsibilities require him/her to work in an area in which such servicing or maintenance is being performed. An individual should not be authorized to perform such job responsibilities and/or operational responsibilities until he/she is properly trained on these procedures and is properly trained to complete such servicing or maintenance tasks. Service and/or Maintenance Work place activities such as construction, installing, setting up, adjusting, inspecting, modifying and maintaining and/or servicing machines or equipment must be subject to the minimum procedures stated herein and any additional procedures required by applicable law, regulation or code. Additional activities, such as lubrication, cleaning or unjamming of machines or equipment, and making adjustments or tool changes, where the individual performing the activity may be exposed to the unexpected energization or start up of the equipment or release of hazardous energy must also be subject to the minimum procedures stated herein and any additional procedures required by applicable law, regulation or code. These minimum procedures must be followed by maintenance and setup personnel. Maintenance personnel must follow such minimum procedures in the event that any type of required repair, cleaning, maintenance, inspections, adjusting, or servicing (e.g., electrical, mechanical, or other such servicing that requires entrance into or close contact with the machinery). Setup personnel must follow these minimum procedures in the event that any type of setup is required (e.g., replacing dies, adjusting guards, adjusting die components / tooling, removal of jammed parts, or other such activities that require entrance into or close contact with the machinery). Machinery and Equipment Unlike small appliances or hand tools, industrial machinery requires more than turning off a switch and unplugging. The power for such equipment comes from multiple, interactive energy sources. If all energy sources are not isolated before service (setup and/or maintenance) is performed, an accidental release of energy could occur which could result in serious injury or even death. These forms of energy include: electrical, pneumatic, chemical, thermal, hydraulic, mechanical, or gravity. When machines or equipment need to be serviced, this energy must be isolated so authorized personnel can safely perform the work. Each individual fitting the above descriptions must be issued locks, with identifying tags, which must be used only by that person. Locks must not be transferable from person to person, and each individual must be held responsible for his/her own locks and keys. Each lock must be numbered and a master list showing the number, and the individual using it, must be under the supervision of the facilities or project site manager. Lockout/Tagout Procedures Lockout/Tagout is the preferred method of isolating machines, or equipment, from energy sources. Tagout is to be performed, instead of lockout, only when there is no way to lockout a machine. The authorized maintenance supervisor must be notified if there is no way to lockout a machine. The authorized maintenance supervisor must then evaluate equipment for future lockout capabilities. Affected individuals must be notified when their machine is to be locked out according to the following method. All types of machinery and equipment mentioned above must be subject to these minimum shutdown, isolation, blocking and securing procedures for Lockout/Tagout. Step One: Preparation for shutdown Before an authorized or affected individual turns off a machine or equipment, the authorized individual shall have a working knowledge of the specific equipment, the type and magnitude of the energy, the hazards of the energy to be controlled, and the method or means to control the energy. Step Two: Machine or equipment shutdown The machine or equipment shall be turned off or shut down using the procedures established for that specific machine or piece of equipment. An orderly shutdown must be utilized to avoid any additional, or increased, hazard(s) to individuals as a result of equipment stoppage. Step Three: Machine or equipment isolation All energy isolating devices that are needed to control the energy to the machine or equipment shall be physically located and operated, in such a manner, as to isolate the machine or equipment from the energy source(s). Step Four: Lockout/Tagout device application All types of machinery and equipment listed above fall under these lockout placement, removal, transfer, and responsibility minimum procedures. Lockout/Tagout devices shall be affixed to each energy isolating device by authorized individuals. Lockout devices, where used, shall be affixed in a manner that will hold the energy isolating devices in a "safe" or "off" position. Tagout devices, where used, shall be affixed in such a manner as will clearly indicate that the operation or movement of energy isolating devices from the "safe" or "off" position is prohibited. Where a tag cannot be affixed directly to the energy isolating device, the tag shall be located as close as safely possible to the device, in a position that will be immediately obvious to anyone attempting to operate the device. Step Five: Stored energy Following the application of Lockout/Tagout devices to energy isolating devices, all potentially hazardous stored or residual energy must be relieved, disconnected, restrained, and otherwise rendered safe. If there is a possibility of reaccumulation of stored energy to a hazardous level, verification of isolation shall be continued until the servicing or maintenance is completed, or until the possibility of such accumulation no longer exists. Step Six: Verification of isolation Prior to starting work on machines or equipment that have been locked out or tagged out, the authorized individual shall verify that isolation and deenergization of the machine or equipment have been accomplished, even though isolation is performed prior to shutdown and is checked at that point. Verify the isolation of the equipment by operating the push button or other normal operating or startup control(s) to make certain the equipment will (continued) MFH1956E 77 SQ Series Specifications BROCK® SUPERB® Low Profile Grain Dryers SQ Installation operate. Return the operating control(s) to neutral or ìoffî position after verifying that the equipment is isolated. The machine or equipment is now locked out and servicing or maintenance may safely begin. Step Seven: Release from Lockout/Tagout (continued) Before Lockout/Tagout devices are removed and energy is restored to the machine or equipment, procedures shall be followed and actions taken by the authorized individual(s) to ensure the following: The machine or equipment: The work area shall be inspected to ensure that nonessential items have been removed and to ensure that machine or equipment components are operationally intact. Individuals Present: The work area shall be checked to ensure that all individuals have been safely positioned or removed. After Lockout/Tagout devices have been removed and before a machine or equipment is started, affected individuals shall be notified that the Lockout/Tagout device(s) have been removed. Step Eight: Lockout/tagout devices removal Each Lockout/Tagout device shall be removed from each energy isolating device by the individual who applied the device. Exception: When the authorized individual who applied the Lockout/Tagout device is not available to remove it, that device may be removed under the direction of the authorized supervisor, provided that specific procedures and training for such removal have been developed, documented and incorporated into the owner’s control program. The owner shall demonstrate that the specific procedure provides equivalent safety to the removal of the device by the authorized individual who applied it. The specific procedure shall include at least the following elements: a. Verification by the owner (supervisor / manager) that the authorized individual who applied the device is not at the facility / project site. b. Making all the reasonable efforts to contact the authorized individual to inform him/her that his/her Lockout/Tagout device has been removed. c. Ensuring that the authorized individual has the knowledge before he/she resumes work at that facility / project site. Shift or Personnel Changes When a shift or personnel change occurs, a designated individual shall ensure the continuity of Lockout/Tagout protection. The designated individual shall provide for the orderly transfer of Lockout/Tagout devices between off-going and on-coming individuals to minimize risk from stored energy. In general, if a piece of equipment is locked out at shift change, the person on the next shift must apply their lock before the individual who is leaving can remove their lock. In the event that no authorized individual or supervisor is available to transfer the Lockout/Tagout device, a designated department lock can be used to lockout the equipment during this time frame. As soon as the next shift authorized individual is available, he/she must ensure the equipment is properly de-energized and then place their own Lockout/Tagout device on the equipment. At this point in time the department lock should be removed and returned to its designated storage location. The department lock is never to be used as an individual lockout protection device while servicing or repairing equipment. Group Lockout/Tagout If more than one individual is servicing or setting up the machinery, each individual will use their own lock on the lockout. This prevents undue exposure to a potential hazard. The last individual working on the machinery will remove his/her lock and the tag indicating the work has been completed. The locks should remain on the switch until all work has been completed unless it is necessary for the machinery to be operable between servicing and/or maintenance and does not expose the worker or operator to any unnecessary danger. Operator Training The owner must provide effective initial training and retraining as necessary and must certify that such training has been given to all workers and operators covered by these minimum procedures. The certification must contain each worker and/or operator’s name and dates of training. For the purposes of these minimum procedures, there are three types of individuals — authorized, affected, and other. The amount and kind of training that each individual should receive is based upon (1) the relationship of that individual’s responsibilities in relation to the machine or equipment being locked and tagged out, and (2) the degree of knowledge relevant to hazardous energy that he or she must possess. For example, the owner’s training program for authorized individuals (those who are charged with the responsibility for implementing the energy control procedures and performing the service and maintenance) must cover, at minimum, the following areas: (1) details about the type and magnitude of the hazardous energy sources present in the workplace; and (2) the methods and means necessary to isolate and control those energy sources (i.e., the elements of the energy control procedures). By contrast, affected individuals (usually the machine operators or users) and all other individuals who have access to such machines and/or equipment must be able to: (1) recognize when the control procedure is being implemented; and (2) understand the purpose of the procedure and the importance of not attempting to start up or use the machinery and/or equipment that has been locked or tagged out. Because an ìaffectedî individual is not one who is performing the service or maintenance, that individual’s responsibilities under these minimum procedures are more simple (i.e., whenever there is a Lockout/Tagout device in place on an energy-isolating device, the affected individual must leave it alone and never attempt to operate the machinery and/or equipment). Every training program must ensure that all authorized and affected individuals understand the purpose, function and restrictions of these minimum energy control procedures and that authorized individuals possess the knowledge and skills necessary for the safe application, use, and removal of energy controls. Training programs used for compliance with these minimum procedures and/or other more stringent applicable procedures, which are performanceoriented, should deal with the equipment, type(s) of energy, and hazard(s) specific to the environment being covered. Retraining must be provided, as required, whenever there is a change in work and/or operational assignments, a change in machines, equipment or processes that present a new hazard, or a change in minimum energy control procedures. Additional retraining must be conducted whenever a periodic inspection reveals, or whenever the relevant authorized supervisor has reason to believe, that there are deviations from or inadequacies in the authorized individual’s knowledge or use of the minimum required energy control procedure. Periodic Inspection A periodic inspection is done, looking at the minimum energy control procedures performed to ensure that such minimum procedures and requirements are being followed. The inspection should be performed monthly by the authorized supervisor with the intent of evaluating the authorized individuals at least once per year. This information should be recorded on a Lockout/Tagout Inspection Sheet / Log. All original copies should be maintained by the owner of the equipment and/or machinery. Outside personnel (contractors, etc.) The owner and any third party contractor engaged to perform installation, maintenance or operation of the equipment and/or machinery must advise each other of their respective minimum Lockout/Tagout procedures. Each party must ensure that his or her personnel must understand and comply with all restrictions and / or prohibitions of the other party’s minimum energy control procedures. Administrative Duties The authorized supervisors are responsible for the daily follow-through of the required minimum procedures for each applicable piece of equipment and/or machinery. Violation of the required minimum procedures set by the owner must be addressed appropriately by the owner and/or authorized supervisor. The owner of the applicable equipment and/or machinery must review and update the required minimum procedures as necessary.
