The Powerex Oilless Rotary Scroll Air Compressor has advanced
scroll compressor technology through the development of a
completely oilless compressor. The Powerex Scroll Compressor
offers a dynamically balanced air end which insures vibration­free operation. The rotary design permits a continuous 100%
duty cycle.

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
fl ammable gases, moisture, water, and direct sunlight.

3. Never install the compressor where the ambient
temperature is higher than 104
high.

4. Clearance must allow for safe, effective 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 qualifi 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 fl 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.

Remote Intake Piping

Powerex Compressor Systems with pipe thread connectors on
the intake fi lters are intended for installation with remote air
intake. Piping for the remote intake system must be installed
at the fi 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 fi 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 suffi cient capacity to capture
liquid water in the intake piping before the air fi lters. Drip
legs must be sized with low enough air velocity to make sure
they are effective at capturing liquid water in the intake air
and must be maintained (drained) at frequent intervals to
make sure they remain effective.

SAFETY VALVES

Tank mounted compressors are shipped from the factory with
safety valves installed in the air receiver manifold. The fl 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. shutoff 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.

2 HP - 5 HP Scroll Enclosure Air Compressors

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. Confi rm that the electric power source and ground have
been fi 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 fi lter is properly installed.

10. Confi 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 qualifi 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 off. Have a qualifi 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 confi 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 fi 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 off 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 defl ection method for
belt tension, 3.8-4.3 lbs force at mid span should give 7/32
inch belt defl ection for a new belt, 3.0-3.38 for a used belt
for 7/32 inch belt defl ection.

4. Tighten the four (4) motor slide bolts. Tighten the two
electrical panel side slide bolts fi 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.
