2 HP - 5 HP Scroll Enclosure Air Compressors
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
Compressor Specifi cations
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.
