Description
GENERAL
The Powerex Oilless Rotary Scroll Air Compressor has advanced
scroll compressor technology through the development of a
completely oilless compressor. The Powerex Scroll Compressor oers a
dynamically balanced air end which insures vibration-free operation.
The rotary design permits a continuous 100% duty cycle.
Other standard features on the Powerex Scroll Compressor include:
a Magnetic Starter, Motor Overload Protection, a High Temperature
Shutdown Switch, an Air Cooled Aftercooler and a Single Phase or
Three Phase 4 Pole ODP motor.
Safety Guidelines
A SEPARATE SAFETY BOOKLET IS PROVIDED ALONG WITH THIS
MANUAL. READ AND UNDERSTAND The SAFETY BOOKLET.
This manual contains information that is very important to know
and understand. This information is provided for SAFETY and to
PREVENT EQUIPMENT PROBLEMS. To help recognize this information,
observe the following symbols. MAKE SURE EVRYONE OPERATING OR
SERVICING THE COMPRESSOR READS AND UNDERSTANDS ALL The
INFORMATION PROVIDED.
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 potentially
minor or moderate injury.
Installation
INSTALLATION SITE
1. The scroll compressor must be located in a clean, well lit
and well ventilated area.
2. The area should be free of excessive dust, toxic or ammable
gases, moisture, water, and direct sunlight.
3. Never install the compressor where the ambient temperature is
higher than 104oF or where humidity is high.
4. Clearance must allow for safe, eective inspection and
maintenance. 20 inches of clearance for sides is recommended.
Installation (Continued)
5. If necessary, use metal shims or leveling pads to level the
compressor. Never use wood to shim the compressor.

6. Never install the compressor outside.
7. For 3 and 5 HP single phase models it is recommended that
additional tank volume be added. 3 HP single phase models
need a minimum of 30 gallons air capacity to limit the number of
starts-per-hour to 14 maximum. 5 HP single phase models need a
minimum of 60 gallons air capacity to limit the number of starts-
per-hour to 10 maximum.
VENTILATION
1. If the scroll compressor is located in a totally enclosed room, an
exhaust fan with access to outside air must be installed.
2. Never restrict the cooling fan exhaust air.
3. Vent the exhaust air outside to prevent the compressor from
operating at high temperatures and shutting down.
4. Never locate the compressor where hot exhaust air from other
heat generating units may be pulled into the unit.
WIRING
All electrical connections must be performed by a qualied electrician.
Installations must be in accordance with local and national electrical
codes.
1. Make sure power source is the same voltage as the unit’s required
voltage
2. Use solderless terminals to connect the electric power source.
3. Remove the two left panels.
4. Pull the electric cable through the electric source inlet and
connect to the primary side of the contact blocks.
5. Since loosening of wires is possible in shipment, tighten all wire
terminals prior to starting the unit.
PIPING
General Guidelines
1. Make sure the piping is lined up without being strained or
twisted when assembling the piping for the scroll compressor.
2. Appropriate expansion loops or bends should be installed at the
compressor to avoid stresses caused by changes in hot and cold
conditions.
3. Piping supports should be anchored separately from the
compressor to reduce noise and vibration.
4. Never use any piping smaller than the compressor connection.
5. Use exible hose to connect the outlet of the compressor to the
piping so that the vibration of the compressor does not transfer
to the piping.
Compressor Specications
Remote Intake Piping
Powerex Compressor Systems with pipe thread connectors on the
intake lters are intended for installation with remote air intake. Piping
for the remote intake system must be installed at the nal operating
site.
Under some conditions, the intake piping may facilitate the
condensation of humidity in the intake air stream into liquid water.
The intake lters supplied by
Powerex will not stop ingestion of liquid
water by the pumps. Liquid water going into the pumps will damage the
pumps and void the warranty.
Always install drip legs with sucient capacity to capture liquid water
in the intake piping before the air lters. Drip legs must be sized with
low enough air velocity to make sure they are eective at capturing
liquid water in the intake air and must be maintained (drained) at
frequent intervals to make sure they remain eective.
SAFETY VALVES
Tank mounted compressors are shipped from the factory with safety
valves installed in the air receiver manifold. The ow capacity of the
safety valve is equal to or greater than the capacity of the compressor.
1. The pressure setting of the safety valve must be equal or less than
the maximum working pressure of the air receiver.
2. Safety valves should be placed ahead of any possible blockage
point in the system, i.e. shuto valve.
3. Avoid connecting the safety valve with any tubing or piping.
4. Manually operate the safety valve every six months to avoid
sticking or freezing.
Operation
BEFORE START UP
1. Make sure all safety warnings, labels and instructions have been
read and understood before continuing.
2. Remove any shipping materials, brackets, etc.
3. Conrm that the electric power source and ground have been
rmly connected.
4. Check the belts for tightness.
5. Be sure all pressure connections are tight.
6. Check to be certain all safety relief valves, etc., are correctly
installed.

7. Securely mount all panels and guards.
8. Check that all fuses, circuit breakers, etc., are the proper size.
9. Make sure the inlet lter is properly installed.
10. Conrm that the drain valve is closed.
STARTUP AND OPERATION
1. Visually check the rotation of the compressor pump. The rotation
should be counterclockwise if viewing the compressor from the
belt side. If the rotation is incorrect, have a qualied electrician
correct the supply wiring.
2. Follow all the procedures under “Before start-up”before
attempting operation of the compressor.
3. Make sure compressor switch is in the OFF position.
4. Switch the electric source breaker on.
5. Open the 3/8 inch discharge valve completely.
6. Turn compressor switch to ON position and check that the
compressor operates without excessive vibration, unusual noises
or leaks.
7. Close the discharge valve completely.
8. If the pressure does not rise on a three phase unit, turn the unit
o. Have a qualied electrician switch the breaker OFF and
exchange the L1 and L2 connections (two out of three phases of
electric source) on the control panel.
9. Check the discharge pressure. Also make sure the air pressure
rises to the designated pressure setting by checking the
discharge pressure gauge.
10. Check the operation of the pressure switch by opening the outlet
valve and conrming the compressor starts at approximately 95
psig for low pressure units and 115 psig or high pressure units.
DAILY OPERATION
1. Stop the compressor by turning switch to the OFF position.
NOTE: If the compressor rotates in reverse for more than ve seconds,
the check valve needs to be cleaned or replaced.
2. Switch the breaker OFF if the compressor is not to be used for a
long period of time.
STOPPING THE COMPRESSOR DURING
NORMAL OPERATION
1. Close the discharge valve.
2. Allow the air pressure to build and the compressor to stop.
3. Turn the compressor o by turning switch to the OFF position.
BELT ADJUSTMENT PROCEDURE
1. Remove the top panel by removing the two slotted 1/4-20 screws
on the rear of the enclosure.
2. Loosen the four (4) motor slide bolts.
3. Tighten belt by adjusting the belt adjustment bolt. Belt tension
for new belts should be 57 to 65 lbs for the loosest belt in the
set, then 45-50 lbs after run-in. If the belt tension falls below 25
lbs or chirping is heard as start up, re-tension belts. (If using the
deection method for belt tension, 3.8-4.3 lbs force at mid span
should give 7/32 inch belt deection for a new belt, 3.0-3.38 for a
used belt for 7/32 inch belt deection.
4. Tighten the four (4) motor slide bolts. Tighten the two electrical
panel side slide bolts rst then tighten the two pulley side slide
bolts.

Notes:
1. Inspect and perform maintenance periodically according to maintenance schedule.
2. The maintenance schedule relates to the normal operating conditions. If the circumstances and load condition
are adverse, shorten the interval 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; 57-65 lbs initially, then 45-50 lbs after run-in.
