2 HP - 5 HP Scroll Enclosure Air Compressors
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 qualied 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 Specications
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 sucient 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 eective at capturing
liquid water in the intake air and must be maintained (drained) at
frequent intervals to make sure they remain eective.
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. Conrm 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.
