All units may be broken down into separate modules that can pass through a 36” wide standard door or service elevator. All refrigerant circuits are factory charged and sealed. Water connections between sections have brass couplings providing for single water connections. VL CABINET The VL design allows for installation in those locations where there is a height restriction. The blower section is dropped into the main coils section reducing the overall height and increasing unit depth. Unit sizes MC480 through MC720 may be split into two sections for transportation and access into the plant room. 970-384 Rev. 12-13 MC SERIES 2 Available options: • Factory installed economizer package • Field installed hot water heating coils • Hot gas reheat • Hot gas bypass • Proof of fluid flow - factory installed differential pressure switch • Entering/leaving fluid temperature sensors • Factory installed freeze protection sensor GENERAL To insure proper operation the units should be rigged, installed and commissioned according to the instructions contained in this manual. All dampers, remote valves, fire/ smoke alarm devices must be field installed according to local/state/national codes as required. Physical space inside the units is limited and these devices can not be mounted within the unit. The units are designed to operate under conditions normally encountered in an air conditioning or heating application. For special applications such as 100% outside air, high or low temperature entering fluid conditions and CFM requirements outside of the units’ normal operating range the factory should be consulted. Likewise if special control sequences are required the factory should be consulted. Off the shelf part substitutions will not be allowed without the express written consent by the factory. This product should not be used for temporary heating or cooling during the construction phase, doing so may void equipment warranties. NOTE: Installation and maintenance on the units are to be performed only by personnel who are qualified, trained and have experience with this type of equipment. CAUTION: Installation and servicing of this equipment can be hazardous due to high system pressures and electrical components. Only trained and qualified personnel should install, repair, or service the equipment. Untrained personnel may perform basic routine maintenance such as cleaning coils or replacing filters. WARNING: Before performing service or maintenance operations on equipment turn off all power supplies to unit. Electrical shock could cause personal injury or death. When working on this equipment, always observe precautions described in literature, tags and labels attached to the equipment. CAUTION: R-410A systems operate at higher pressures than R-22. Do not use R-22 service equipment or components on R-410A equipment. Number of Sections Sections (Refer to marketing brochure for further details) SAFETY CONSIDERATIONS The FHP MC-series heat pumps are designed to provide the best combination of performance and efficiency available. Safety devices are built into each unit to provide the maximum system protection possible when equipment is properly installed and maintained. All units are Underwriters Laboratories (UL) and (CUL) listed for safety. All units are performance tested in accordance with ARI standard 320 for water source heat pumps FHP Manufacturing recommends that you always order the water coil insulation option on all units that will operate below 50 °F. FHP will not be responsible for any damage due to condensation. MC480 MC600 MC720 VH VL VH VL VH VL VH VL Air conditioning 1 1 2 2 2 2 2 2 Economizer/Filter 1 1 2 2 2 2 2 2 Fan 1 – 2 – 2 – 2 – USE SPREADER BARS TO PREVENT DAMAGE TO UNIT. The units are designed to operate with entering fluid temperatures between 45 and 110 degrees F. (note: for low entering fluid temperatures an insulation package should be ordered to eliminate heat exchanger and fluid piping sweating.) Antifreeze solutions should be used on all condenser water loop applications where low fluid temperature conditions may occur. FHP Manufacturing will not be responsible for freeze damage that may result from misapplication. This applies to all heat exchangers that may be involved and/or other component damage and consequent damage that may occur due to freezing. The antifreeze solution needs be inhibited to prevent corrosion of the water circuit. MC360 4 X 4 ABOVE AND BELOW RETURN DUCT CONNECTIONS Figure #1 970-384 Rev. 12-13 MC SERIES 3 CAUTION: The coil and unit may contain sharp edges that are a potential injury hazard. Protective equipment should be worn and care should be exercised to avoid contact with them. requirements, contact an acoustical consultant for guidance and recommendations. Follow all safety and local codes and regulations. Wear safety glasses and work gloves. Use a quenching cloth when performing brazing operations and place a fire extinguisher close to the work area. The equipment room should, where possible, be located on the ground floor or area away from any and all sensitive work areas. Whenever possible, work with the architect to locate the equipment rooms around the perimeters of restrooms, hallways, fire escapes, stair wells, etc to reduce noise transmission. This allows not only for isolation from radiated sound but also enables the contractor to route duct systems around sensitive locations. MOVING AND STORAGE Units may be shipped in multiple sections depending on the model. Move all units in the normal upright position. Do not stack units. When the equipment is received all items should be carefully checked against the bill of lading to be sure all crates and cartons have been delivered. Examine all units for shipping damage, uncrating the units if required. Units in question should also be internally inspected. If units are damaged, the carrier should make the proper notation on the delivery receipt acknowledging the damage. The receiver is responsible for filing freight damage claims with the carrier. FHP will not be responsible for equipment damaged during transit. Refer to Figure #1 for lifting details. Units must be properly rigged with spreader bars as appropriate to avoid damage to the unit. LOCATION Locate the unit in an indoor area that allows easy removal of the filters, access panels, and accessories. Make certain enough space is available for service personnel to perform maintenance or repairs. Provide sufficient room to make all water, duct, and electrical connections to the unit. If the unit is located in a small mechanical equipment room make sure adequate space is available for air to return freely to the unit. These units are not approved for outdoor installations and therefore must be installed inside the structure. Do not locate in areas that are subject to freezing. Care should be taken to insure that the floor is structurally strong enough to support the weight of the equipment with minimum deflection. A good, level floor is required to insure proper fit-up and alignment of all bolt together and union coupled modules. Isolation springs should be utilized to minimize sound and vibration transmission. Unit fresh air intakes should be located away from building flue stacks or exhaust ventilators. Consult code requirements for fresh air volume requirements. Where code considerations, such as NEC, require extended clearances, they take precedence over suggested clearances contained in this manual. ACOUSTICAL CONSIDERATIONS Proper acoustical considerations are a critical part of every systems design and operation. Multiple scroll compressors, equipment liners, balanced fans, and heavy duty construction makes the MC-series heat pumps inherently quiet. Each system design and installation should be reviewed for its own unique requirements. For job specific EQUIPMENT ROOM The equipment room should be acoustically sealed. Doors should be gasketed to provide an air tight seal to inhibit return air whistle below or around the doorframe. Equipment room construction should be concrete block or double stud construction. This decision will be determined by the specific application. All partition walls should be acoustically insulated. DUCTWORK A supply air outlet collar and return air duct flange are provided on all units to facilitate duct connections. Refer to dimensional drawings for connection sizes. NOTE: Variations in number and orientations of the blowers may alter the location of the connection locations. Refer to the factory for actual unit configuration. A flexible canvas duct connector is recommended on both supply and return air sides of the units to be connected to the system ductwork. All metal ductwork should be adequately insulated to avoid heat loss or gain and to prevent condensation from forming on the ductwork walls. Uninsulated ductwork is not recommended, as the units’ performance will be adversely affected. If the unit is to be installed in a new installation the system should be designed in accordance with ASHRAE procedures for duct sizing. If the unit is to be connected to existing ductwork, a check should be made to insure the existing duct system has the capacity to handle the airflow required at the system static pressure. If the ductwork is inadequate larger ductwork should be installed. The duct system and diffusers should be sized to handle the design airflow volumes quietly. To maximize sound attenuation of the unit’s blower(s), the supply and return air plenums should be insulated for a length of at least 15 feet from the unit. There should be no direct line of sight from return air grilles into the units’ return. If return air is to be ducted to an equipment room an elbow should be installed within the equipment room. Running a return air drop to near the floor of the room will aid in sound attenuation. Care should be taken to avoid transmitting vibrations generated by the movement of air in the ducting to the walls of the building. This is particularly important where ducting penetrates walls. The maximum recommended return air velocity is 1,000 feet per minute. The lower the return air velocity the lower the resulting sound power levels will be. The use of round supply duct plenums 970-384 Rev. 12-13 MC SERIES 4 should be considered, as it will significantly reduce low frequency sound at the equipment room. If rectangular supply plenums are used, the aspect ratio of the duct should be kept as small as possible. The large flat surface areas associated with large aspect ratio duct systems will transmit sound to the space and the potential for duct generated noise, such as oil canning, is increased. The maximum recommended supply air duct velocity is 2,000 feet per minute. Fan discharge orientation may be either front or back (VH series) and either top or front (VL series). See unit drawings pages 15-18. Units having two fans should have a properly designed pants duct connection. An adequate straight length of ducting from the unit should be allowed before elbows are installed. If ducting an elbow directly to the fan outlet, a minimum straight length of two fan diameters from the fan outlet is recommended. The elbow should turn in the direction of fan rotation if possible. Abrupt turns will generate air turbulence and excessive sound. Turning vanes should be utilized in all short radius bends. Ensure that ducting does not obstruct access to the unit for routine servicing. SENSORS Various sensors are available depending on the control package options. Please refer to your specific unit for details. On VAV systems, the static pressure sensor is field mounted and requires the installation of sensor tubing. The sensor tubing sensing point should be located near the end of the main supply trunk duct in a position free from turbulence effects and at least 10 duct diameters downstream and 4 duct diameters upstream from any major transitions or branch take-offs. Incorrect location of the sensing point could result in improper operation of the entire VAV system. The tube end should be perpendicular to the airflow to ensure that only static pressure is sensed. Ensure that tubing conforms to local codes. Pressure sensors should be wired to MCS or other controller. The static pressure control should be adjusted so that, at full airflow, all of the remote VAV terminal boxes receive the minimum static pressure required plus any downstream resistance. Control the system to the lowest static pressure set point that will satisfy airflow requirements. Lower static pressure set points reduce total required brake horsepower and reduce generated sound levels. Zone temperature/humidity sensor placement is critical to insure proper and economical unit operation. It is recommended that space sensors be located on an inside (partition) wall and a minimum of 3 to 5 feet from the nearest outside wall. The sensor should not be located near a supply diffuser or return air grille nor in direct sunlight, drafty areas, or next to an unoccupied or unconditioned space. Where zone temperature sensing requirements present a problem, return air control strategies may be utilized. CONDENSER WATER PIPING Always follow National and Local codes in the installation of water piping to ensure a safe and proper installation. Connections to the unit should incorporate vibration eliminators to reduce noise and vibration to the building and shutoff valves to facilitate servicing. Prior to connecting the units to the condenser water system, the system should be flushed to remove foreign material that could foul the condensers. No unit should be connected to the supply or return piping until the water system has been completely cleaned and flushed to remove any dirt, piping chips or other foreign material. Supply and return hoses should be connected together during this process to ensure the entire system is properly flushed. After the cleaning and flushing has taken place the unit may be connected to the water loop and should have all valves wide open. A strainer is recommended at the inlet to each unit to remove foreign material from fouling the condensers. Supply and return water piping must be at least as large as the connections on the unit. Units may be furnished with either a copper or optional cupro-nickel heat exchanger. Copper is adequate for closed loop heat exchanger systems or systems where good quality water is available. In conditions where scale formation or water treatment is questionable cupro-nickel heat exchangers should be used. Intermediate plate frame heat exchangers are recommended where the water is corrosive or could lead to excessive fouling. CAUTION: Galvanized pipe or fittings are not recommended for use with these units due to the possibility of galvanic corrosion caused by dissimilar metals. When selecting piping materials, utilize only approved piping materials that meet applicable codes and that will handle the temperatures and pressures that may be experienced in the application. Piping systems will sweat if low temperature fluid is used in the system. In these jobs supply and return piping should be insulated to protect from damage resulting from condensation. Minimum recommended EWT to the unit is 45°F. Typically cycling fans or modulating discharge dampers may be used to modulate the water temperature from the heat rejecter. A three-way bypass valve around the tower could also help regulate the condenser water temperature. A glycol solution should be used if ambient temperatures are expected to fall below freezing or if the loop water temperature is below 50°F while operating in the reverse cycle heating mode. Refer to the chart of freezing points of glycol for a suitable concentration. A minimum concentration of 20% is recommended. Water pressure drop will increase and unit performance Freeze point °F % Glycol Ethylene Glycol Propylene Glycol 18 19 20 30 7 9 40 -7 -5 50 -28 -27 970-384 Rev. 12-13 MC SERIES will decrease with increasing glycol concentrations. Units mounted with waterside economizer have cooling water passing through the economizer and condenser in series while operating in the economizer mode. During normal operation water bypasses the economizer coil. All manual flow valves used in the system should be of the ball valve design. Globe or gate valves must not be utilized due to high pressure drops and poor throttling characteristics. Do not exceed recommended condenser fluid flow rates. Serious damage or erosion of the heat exchangers tubes could occur. Piping systems should not exceed 10 feet per second fluid velocities to insure quietness and tube wall integrity. Please refer to the condenser water pressure drop table (Page 10). Flow rates outside of the published range should not be used. 5 CAUTION: Operation of the unit on improper line voltage or with excessive phase imbalance can result in damage to the unit and constitutes abuse that may not be covered under warranty. All secondary voltage wiring should be 18-awg minimum. Where longer runs are required larger wire may be required. All MCS sensor wiring should be 18 awg shielded cable with an integral ground. CAUTION: If a two stage controller is utilized for a four compressor unit (MC480 through MC720) we recommend field installing isolation relays to switch the downstream compressors as the electrical load required may exceed the contract rating of the controller. Please refer to Figure #2. Improper fluid flow due to valving, piping or improper pump operation constitutes abuse that may result in warranty invalidation FHP will not be responsible for damages or failures resulting from improper piping design or piping material selection. CONDENSATE WATER CONNECTIONS The condensate water connection is 1.25” FPT and located on the water connection side of the unit. Drain lines should be pitched away from the unit with a minimum slope of 1/8” per foot and conform to all local and national codes. Drain pans should be cleaned periodically to avoid the build up of dirt and bacterial growth. Figure #2 ELECTRICAL WIRING METHODS WARNING: All field wiring must comply with local, state and national fire, safety and electrical codes. Power to the units must be within the operating voltage range indicted on the units’ nameplate and in the performance data tables. Units will normally operate within ± 10 % of rated voltage at the units power terminals. Three phase lines must be balanced within 2 % of each other. Compressor circuits are individually branch fused and motor circuits are protected via a solid sate motor overload/starter. Properly sized fuses or HACR circuit breakers must be field installed for main power protection. See unit data plate and specifications for maximum over current protective device sizes. The units are provided with single point, main power supply terminal blocks. The main terminal block is wired to the second modules terminal block to accomplish single point modular design concept. A means of disconnection the unit in terms of the NEC or other applicable codes should be field supplied and installed. A ground lug is located in the main modules control box for field grounding. Connect power supplies according to the wiring diagrams in this manual and also in the units control box cover. SAFETY DEVICES AND THE UPM CONTROLLER Each MC unit is factory provided with a Unit Protection Module (UPM) that controls compressor operation and monitors the safety controls that protect the unit. Unit sizes 480-720 will have a board in each section. Safety controls include the following: • High pressure switches located in the refrigerant discharge lines. One per refrigeration circuit. • Low pressure switches for loss of charge protection located in the unit refrigerant suction lines. One per refrigeration circuit. • The default setting for the freeze limit trip is 30°F; however this can be changed to 15°F by cutting the R17 for Compressor 1 and R77 for Compressor 2 resistor located on top of the DIP switch SW1. The UPM controller will constantly monitor the refrigerant temperature with the sensor mounted close to the condensing water coil between the thermal expansion valve and water coil as shown in figure 3. 970-384 Rev. 12-13 MC SERIES 6 Power: Physical: 24VAC ± 10%, 50-60Hz, 1.4 VA of standby power consumption (Single Class II 70VA or 100VA option available) Printed Circuit Board and plastic stand offs. -40° to 176°F (-40 °C to 80°C); 10 to 90% relative humidity, non-condensing. All controls are conformal coated for environmental protection. Freeze Protection Sensor Digital Outputs: Figure #3 Three digital outputs relay contacts rated at 10A resistive @ 125 VAC; Two dedicated for the compressor contactor 24VAC when “ON” and one dedicated for alarm purposes dry contact Normally Open (NO) Four (9) inputs. Dedicated inputs for: NOTE: If the sensors are not installed jumpers must be terminated during the commissioning process. • 2 High Pressure Switches (HPC) The unit will not run unless the jumpers for the respective sensors (frz1 and frz2 )are set. • 2 Low Pressure Switches (LPC) • Optional Condensate overflow protection sensor located in the drain pan(s) of the unit and wired to the UPM board. Inputs: • 2 Freeze Sensors (FREEZE) 10 K @ 77F Thermistor • 1 Condensate Overflow Sensor (CON) 230 K +/- 15% The UPM includes the following features: • Status Indication Protection: 2 Compressor Call (Y) Signals Visual (LED) status of power and alarms status indication. Surge and transient protection circuitry. 970-384 Rev. 12-13 MC SERIES 7 UNIT PROTECTION MODULE (UPM) The Unit Protection Module (UPM) as shown in figure 4, is a printed circuit board (PCB) that interfaces with the thermostat or the digital direct controller. The main purpose of this device is to protect the compressors by monitoring the different states of switches and sensors of each refrigerant circuit, this device provides time delays and protects the unit against freezing of the water and refrigerant heat exchangers as well as condensate overflow when the appropriate sensors are installed. NOTE : If the board is set to test mode through the “TEST” DIP switch the delay will be 5 seconds. Y CALL The UPM will energize the compressor’s output (CC) in an event of a “Y” call from a thermostat or controller (after the random start up and/or the anti short cycle delays have elapsed). Y input terminal must be energized with a 24 VAC signal. HIGH AND LOW PRESSURE PROTECTION The UPM monitors the state of the High and Low pressure Switch inputs of each refrigerant circuit, HP1, LP1 and HP2 and LP2 on the board respectively, these switches must be closed in order for the controller to energize the compressor output (CC1 and CC2). The CC output will only be energized when the switches are closed and the anti short cycle (and / or random start up when applicable) has expired. HIGH PRESSURE PROTECTION If the HP1 or HP2 switches are open upon a Y1 or Y2 call the UPM will not energize the respective CC1 or CC2 outputs and therefore the correspondent compressor will remain off, the fault LED will flash one (1) time for the HP1 and 3 times for HP2 and the alarm contact will remain off. Figure #4 Alarm output is Normally Open (NO) dry contact. If 24 VAC output is needed R must be wired to the ALR-COM terminal; 24VAC will be available on the ALR-OUT terminal when the unit is in alarm condition. If pulse is selected the alarm output will be pulsed. POWER RANDOM START UP This feature prevents multiple units sharing same electrical circuit or network from starting at the same time. It assures that Heat Pumps sharing the same electrical circuit do not demand high inrush currents simultaneously when starting back up after a power failure. If the controller has been completely powered down for more than 28 milliseconds, a random delay is initiated typically the unit will start between the time range of 270 and 300 seconds, this only if the controller is set to normal operation (test switch set to NO). In order for the random sequence to initiate the unit power must be removed completely. IMPORTANT : If the board is set to “TEST” mode through the “TEST” DIP switch SW1 delay will be 10 seconds. ANTI SHORT CYCLE DELAY This feature protects the compressor short cycling if the Y call is set and removed. The anti short cycle delay is 300sec delay on break during normal operation. If a compressor is running in normal mode on a Y call (Could be Y1 or Y2 or both) and the high pressure switch opens, the UPM will shut down the compressor output and will keep it off until the switch closes and the anti short cycle has expired. The controller will keep track of the number of times the switch opens, if within one (1) hour period the switch opens the number of times set via the DIP switch the controller will shut the compressor down and perform a hard lockout condition under this condition the alarm contact will be energized. The UPM allows the user to configure the counts that the HP will be allowed to open within one hour before the UPM performs a hard lockout on the compressor. The user can select either two or four times by changing switch four (4) on the DIP switch SW1 (shown on table 3) on the UPM board. LOW PRESSURE PROTECTION If the LP1 or LP2 switches are open upon a Y1 or Y2 call (Could be Y1 or Y2 or both) the UPM will not energize the CC1 or CC2 outputs and therefore the correspondent compressor will remain off, the fault LED will flash two (2) times for the LP1 and 4 times for the LP2 and the alarm contact will remain off. If the compressor is running in normal mode on a Y call (Could be Y1 or Y2 or both) and the low pressure switch opens, the UPM will keep the compressor running for two (2) minutes if the condition remains after this period of time the compressor will shut down and the UPM will start a soft lockout. The UPM will flash two (2) times for the LP1, four (4) times for the LP2 and the alarm contact will remain off. If the switches close, the UPM will start the compressor after the anti short cycle has expired UPM will energize the compressor output. 970-384 Rev. 12-13 MC SERIES 8 IMPORTANT : To exit the hard lockout the controller must be reset from the Y or R terminal by removing the power from the selected terminal. The user can choose which will be the reset point via the DIP switch SW1. SELECTABLE ALARM MODE The UPM controller can be configured to have either a constant signal or a pulse. If constant (CONT) is selected the UPM will provide a closed contact until the alarm is cleared. GROUND The UPM controller takes its ground reference from the unit chassis which is connected to the controller via the C-GND spade terminal. If pulsed (PULSE) is selected the UPM will sequence the alarm contact with the fault LED flashes. DIP SWITCH SETTINGS The default setting for the freeze limit trip is 30°F; however this can be changed to 15°F by cutting the R17 for Compressor 1 and R77 for Compressor 2 resistor located on top of the DIP switch SW1. The DIP switch is used to configure most of the available features of the UPM as follows: • Alarm mode, Constant or Pulse • Reset mode, Y signal or R signal • Lockout mode, two (2) or four (4) Strikes • Test mode, Normal or Test operation The UPM controller will constantly monitor the refrigerant temperature with the sensor mounted close to the condensing water coil between the thermal expansion valve and water coil as shown in figure 4. The settings shown below (figure 5) are factory default for most heat pump applications, however the Unit wiring diagram is the ultimate guide for factory DIP switch default settings. If temperature drops below or remains at the freeze limit trip for 30 seconds, the controller will shut the compressor down and enter into a soft lockout condition. Both the status LED and the Alarm contact will be active. The LED will flash (five (5) times) the code associated with this alarm condition. 4 Lockout 3 Reset 2 BROWNOUT PROTECTION Alarm The controller will not monitor the power supply during the first 500 milliseconds of compressor start up to avoid noise and false alarms. 1 ON FREEZE PROTECTION Test Once the UPM detects a brownout condition its fault LED will flash seven (7) times as error code indication. The UPM controller will constantly monitor the power supply, if the nominal voltage drops below 25% of its value. (18 VAC approximately), the unit will enter brownout protection mode. The compressor CC outputs will be de-energized and the unit will enter the soft lockout mode. CONDENSATION OVERFLOW Figure #5 The following table is available on the UPM board as well and it depicts the switch position and its associated functionality. UPM Dip Switch Configuration 4 LOCKOUT 4 2 3 RESET R Y 2 ALARM CONT PULSE 1 TEST YES NO The UPM controller continuously monitors the drain pan for high condensate water level, and to do so it utilizes a sensor and identifies an alarm condition when the sensor’s impedance drops below 230KΩ +/- 15 %. (ONLY when condensate sensor option is present) Once the UPM senses this resistance value it enters into a hard lockout and reports the correspondent code via its status LED (6 flashes). To exit the hard lockout water has to return to its normal level and UPM has to be reset by removing the power from the Y terminal (R if set on the DIP switch) the compressors will be turned on after anti short cycle expires. SEQUENCE OF OPERATION The UPM sequence of operation illustrated in the flow chart applies for both refrigerant circuits. The second compressor is energized 10 seconds after the first if both Y1 and Y2 signals are applied at the simultaneously. 970-384 Rev. 12-13 MC SERIES 9 UPM Sequence of Operation (SOO) Flow Chart Y1=1 NO YES Power/Switchs/Sensor Status Check V > 18VAC NO Lockout Can Be Set To 4 Via Dip Switch YES HPC = 1 Blink Code On Status LED Soft Lockout Record Alarm Start Counter (If Applicable) NO YES LPC = 1 NO Start Timer TIME > 120 SEC NO FRZ > TEMP LIM NO Start Timer TIME > 30 SEC YES CC Output = Off NO YES Blink Code On Status LED Report Alarm Fault Hard Lockout ALR Output = On/Pulse NO YES INITIAL NO POWER UP YES NO YES YES YES CON > 0 COUNT = 2 Start Anti Short Cycle Start Random Start Up NO T > ASC OR RS SEC YES CC Output = On 970-384 Rev. 12-13 MC SERIES 10 NOTE: The blower motor will remain active during a lockout condition. OPTIONS HOT WATER HEATING COIL A factory supplied, field installed one or two row hot water heating coil is available for cooling only units. The coil is supplied with hot water from a boiler through separate piping than the condenser water loop. All controls for heating operation are field supplied. HOT GAS REHEAT Operation of the hot gas reheat cycle is initiated by a humidistat sensing space humidity. On a rise in humidity the unit will operate in the cooling mode with the hot gas reheat solenoid valve energized. Once the humidity drops below the set point the unit will cycle off. Cooling set point will take priority over the humidity set point and the unit will operate in the cooling mode until the space temperature is satisfied. WARNING: • Only qualified service personnel should perform start up and service on the machine. • Ensure that the unit is property grounded, failure to do so may result in electric shock. • Always disconnect electric power before servicing the unit. Throw away construction filters should be field installed to protect the main filters during the construction period. that the supply is within the unit acceptable limits. Check that power wiring is adequate as per unit nameplate. 9) Check that all electrical and mechanical work conforms to local and national codes and requirements. 10) Ensure that all valves are open. START-UP Ensure that the cooling set point is below the space ambient temperature so that the unit will operate when started. Start all auxiliary equipment such as pumps, cooling towers etc. Manually start the fan only and check fan rotation. If the rotation is incorrect (clockwise when viewed from drive end) reverse two incoming power cables. Always check compressor rotation separately. Failure to do so will void warranty. If the fan is rotating in the correct direction the compressors should also be rotating correctly. If the unit is not cooling (or heating) and the compressors are noisy compressor rotation should also be checked. Set unit to automatic operation. Unit should start and after the time delay the compressors (or economizer coil valve) should start. Check and record all operating temperatures and pressures of the unit once it has reached steady state operating conditions. This record, together with the setpoints will provide a useful reference point for the unit performance at a later date. FAN SPEED CHANGES Units are provided with fixed sheaves. Should the air CFM be above or below requirements a pulley change will be required. PRE-STARTUP 1) Prior to starting the unit, ensure that it is properly installed with ducting and water piping connected. 2) Water loop must be flushed to remove all foreign matter before connection to the unit. Air filters must be installed and clean. 3) With the unit disconnected check to see that all electrical connections are tight as they may have loosened during transport and installation. 4) Check tightness of all water pipe unions to ensure no leakage. 5) Check tightness of all set screws in bearings and drives. Make sure the fans rotate freely and check belt tension and alignment of the pulleys. 6) Ensure that all the sensors have been properly located and connected to the unit. 7) Review the unit control sequence to become familiar with the unit operation, control sequence and safety functions. 8) Verify that the unit voltage matches the supply and WARNING: • Only qualified service personnel should perform start up and service on the machine • Ensure that the unit is property grounded, failure to do so may result in electric shock • Always disconnect electric power before servicing the unit Regular service inspections on a unit are the best way to ensure an efficient operating system and avoid premature failures. Maintenance should, at a minimum, cover the following: • Clean or replace filters depending on the type. Frequency of service will depend on the severity of operating conditions • Check drive components and belt tension for signs of abnormal wear. Lubricate bearings • Clean evaporator coils 970-384 Rev. 12-13 MC SERIES • Clean condensate pan as required • Condensers may be chemically cleaned if necessary. An indication of increased fouling of the condenser is an increase in the temperature difference between leaving condenser water and condensing temperature or an increase in condensing pressure/temperature with the same leaving condenser water temperature. 11 • Check and record all operating pressures and temperatures. Review the data against previous reading to see if there are any trends from previous readings that may indicate a need for service • If a glycol solution is used the condition and concentration of the solution should be checked The unit controller will provide a record of fault occurrences.
