Description General
Breathable Air Warning
Powerex Scroll Enclosure Air Compressors are designed to supply continuous oil-free air by using the most advanced scroll technology. These turn-key packages are extremely quiet and offer electronic control that will reduce electrical power consumption.
This compressor/pump is not equipped and should not be used “as is” to supply breathing quality air. For any application of air for human consumption, you must fit the air compressor/ pump with suitable in-line safety and alarm equipment. This additional equipment is necessary to properly filter and purify the air to meet minimal specifications for Grade D breathing as described in Compressed Gas Association Commodity Specification G 7.1 - 1966, OSHA 29 CFR 1910. 134, and/or Canadian Standards Associations (CSA).
The Powerex Oilless Rotary Scroll Air Compressor has advanced scroll compressor technology through the development of a completely oilless unit. The Powerex Scroll Compressor offers a dynamically balanced air end which insures vibration-free operation. The rotary design permits a continuous 100% duty cycle. No oil separation, oil filtration, or inlet valves are required on the Powerex Scroll unit. The compressor is virtually maintenance free.

23 Do not operate the compressor if unusual noise or vibration occurs. 24. Keep all panels in place at all times.
Bearings
25. Standard motors are not appropriate for dirty, wet or explosive areas. 26. All service should be performed by trained and qualified people only.
The bearings on the scroll compressor are regreaseable to allow extended compressor life. Service should be performed every 10,000 hours (5,000 hours for high pressure models) of operation.
27. The Drive Belt tension should be checked often during initial operation of the compressor.
Air Cooled Aftercooler
28. Never substitute oil bath or oil wetted filters for the inlet filters provided with the compressor.
The air cooled aftercooler on the scroll compressor is a series of deep alloy cooling fins and a high output cooling fan. These cooling features allow the scroll compressor to provide a maximum discharge air temperature of 63°F above the ambient temperature.
Component Description Compression Cycle
Dry Type Inlet Filter
The Powerex Oilless Rotary Scroll Air Compressor is based on the theory of scroll compression. A scroll is a free standing, intricate spiral bounded on one side by a solid, flat plane or base. A scroll set, the basic compression element of a scroll compressor, is made up of two identical spirals which form right and left hand parts. One of these scroll components is indexed or phased 180° with respect to the other so the scrolls can mesh. Crescent-shaped gas pockets are formed and bounded by the spirals and the base plate of both scrolls. As the moving scroll is orbited around the fixed scroll, the pockets formed by the meshed scrolls follow the spiral toward the center and diminish in size. The moving scroll is prevented from rotating during this process so the 180° phase relationship of the scrolls is maintained. The compressor’s inlet is at the outer boundary of the scrolls. The entering gas is trapped in two completely opposite gas pockets and compressed as the pockets move toward the center. The compressed gas is discharged through the outlet at the center of the fixed scroll so no valves are needed.
The inlet filter on the scroll compressor assures 99% of particulate free air is admitted to the unit. Change every 2,500 hours or more often in dirty locations. These filters can be accessed from the front door. Cooling Air Cleanable Filter Screen The cooling air cleanable filter screen on the scroll compressor is located on the rear of the unit and should be cleaned periodically. Digital Hourmeter The hourmeter on the scroll compressor indicates the actual number of total run hours of all air ends that have been in operation. The hourmeter is also used to determine maintenance and service timing. The hourmeter is activated when one or more air ends is/are running.

Wiring
Component Description (Continued)
All electrical hook-ups must be performed by a qualified electrician. Installations must be in accordance with local and national electrical codes.
High Temperature SHUTDOWN feature
1. Use solderless terminals to connect the electric power source.
The high temperature shutdown feature on the scroll compressor protects the unit when an unusually high temperature in the air end is detected. The compressor will shutdown when this high temperature is detected.
2. Remove front panel. 3. Remove the rectangle electrical box cover located beneath air inlet filter on the right front of the unit.
Installation
4. Connect the power inlet cable to the inlet power junction block located on the inlet side of all starter connections.
Installation Site
Consult your NEC and local codes for wire size
1. The scroll compressor must be located in a clean, well lit and well ventilated area. A contaminated area can clog the intake filter and/or intake metal mesh.
Piping These units do not include air receivers. An air receiver can be purchased separately. Please consult our distributors. Use Chart 2 as a guideline for sizing the air receiver.
2. The area should be free of excessive dust, toxic or flammable gases, moisture and direct sunlight.
1. Make sure the piping is lined up without being strained or twisted when assembling the piping for the scroll compressor.
3. Never install the compressor where the ambient temperature is higher than 104°F or where humidity is high. High humidity will cause electrical short circuit and rusting of components.
2. Appropriate expansion loops or bends should be installed at the compressor to avoid stresses caused by changes in hot and cold conditions.
4. Clearance must allow for safe, effective inspection and maintenance. 28 in. of clearance for sides, 48 in. clearance from the top is recommended.

1. If the scroll compressor is located in a totally enclosed room, an exhaust fan with access to outside air must be installed.
3. Piping supports should be anchored separately from the compressor to reduce noise and vibration.
2. Never restrict the cooling fan exhaust air.
4. Never use any piping smaller than the compressor connection.
3. Vent the exhaust air outside to prevent the compressor from operating at high temperatures and shutting down.
5. Use flexible hose to connect the outlet of the compressor to the piping so that the vibration of the compressor does not transfer to the piping.
4. Never locate the compressor where hot exhaust air from other heat generating units may be pulled into the unit. Suggested ventilation system 1) The following ventilation capacity is designed to keep the temperature rise inside the room to be max. 10°F. Since the calculation is based on zero static pressure, the actual ventilation capacity should be larger than the figure in Chart 1.
Safety Valves
2) Install the exhaust duct in order to minimize the pressure lost of the ducting. Keep the distance between the inlet duct and the compressor exhaust to be at least 12 inches for ease of maintenance. Intake section of the duct should be larger than the dimension of compressor exhaust shown below:
1. The pressure setting of the safety valve must not be greater than the maximum working pressure of the air receiver.
Model Ventilation Capacity (cfm)
These units have a safety valve, but install a safety valve in the air receiver manifold for your safety. The flow capacity of the safety valve is equal to or greater than the capacity of the compressor.
2. Safety valves should be placed ahead of any possible blockage point in the system, i.e. shutoff valve.

Control Sequence As this compressor uses plural air ends, it employs multistage control. It can start and stop each air end according to pressure and air consumption, automatically select the number of air ends in accordance with air consumption and achieve optimum and uniform operation at all times as well as energy-saving and labor-saving operation.
shorter, thus resulting in equalization of operating time of each air end and operation with a min. quantity of air ends in accordance with air consumption and energy-saving operation by eliminating waste of electricity.
1. Multi-stage control
When operating time of an air end exceeds the set time, it changes operation from that air end to the one which has stopped, prevents long-term operation of one air end, lengthens the lifetime of air ends and equalizes the operating time of air ends.
2. Prevention of long-term operation
Among air ends which are operating under group control, it stops the air end which has been operating for a longer time and restarts the air end whose operating time has been

NOTES: 1. Inspect and perform maintenance periodically according to maintenance schedule. 2. The maintenance schedule relates to the normal operation conditions (maximum ambient temperature of less than 104° F and yearly average ambient temperature of 85°F). If the circumstances and load condition are adverse, shorten the cycle time and perform maintenance accordingly. 3. *Marked “Readjust” means the tension of the V-belt should be adjusted during the initial stage and inspected every 2,500 hours afterwards. Chart 17 - Maintenance

6. Remove the old dust seals from fixed scroll, see Figure 12.
2. Remove the nuts and bolts and then the fixed scroll from the air end.
Install the new tip seals and dust seals in the stationary and orbiting scroll housings in the following manner:
3. Grease all three pin crank bearings as indicated on the grease delivery Chart 19 above.
NOTE: Tips seals for Fixed Scroll and Orbit Scroll have opposing seal cut angels (See NOTE and explanatory diagram below).
Use only Powerex genuine grease. (Part # IP600000AV). Pump grease gun before feeding to eliminate air from grease passage of the needle adapter.
The grease fitting, located in the center of the pin crank bearing, feeds only the orbit scroll side bearing. Use a needle adapter to supply grease to the housing side bearing. Pump grease gun before feeding to eliminate air from grease passage of the needle adapter. Hold grease gun for 5 - 10 seconds after feeding to prevent grease blowback from the grease fitting.
Replace Tip Seal 1. Remove intake hose 2. Remove the discharge hose. Figure 12
NOTE: In order to distinguish between the tip seal for Fixed Scroll and the tip seal for Orbit Scroll place the tip seal as shown below then view from the arrow direction and refer to the figures on the right. Fixed Scroll

4. Insert new backup tube in the FS Scroll in the 6 o’ clock position (See Figure 15). 5. Insert new dust seal on the backup tube. 6. After replacing tip seal set, reassemble Fixed Scroll set to the Orbit Scroll. Tighten nuts and bolts temporarily and confirm if pump pulley rotates smoothly by hand and tighten them firmly. Tightening torques are:
Insert tip seal so that the lip of tip seal is on the bottom of seal groove and inner side of involute and the direction of lip faces the center of involute (curving spiral). See Figure 13. This is to be done for both FS and OS sets. Use caution not to tear or distort lip.
Bolt Torque
1. Insert new HP tip seal from the center section for OS or Orbit Scroll so that there will be no clearance at the tip (start) section (See Figure 11 and 13). 2. Insert so that new LP tip seal will contact closely with HP tip seal inside Scroll Groove.
