INSTALLATION
GENERAL – On receipt of the unit, check for any dam-
age that may have been incurred during transit. Report
any damage or missing parts as soon as possible.
Do not electric weld on the compres-
sor or base; bearings can be damaged
by passage of current.
LIFTING UNIT – Proper lifting and/or transporting
methods must be used to prevent damage. Lifting slots
are provided in the base for towmotor use. The unit may
also be moved into location by rolling on bars.
Lift compressor unit by base only. Do
not use other places such as motor,
compressor or discharge manifold
piping as lifting points.
The eyebolts or lugs provided on the
motor are for lifting the motor only
and should not be used to lift any
additional weight. All eyebolts must
be securely tightened. When lifting
the motor the lifting angle must not
exceed 15 degrees. Failure to observe
this warning may result in damage to
equipment or personal injury.
Compressor, air/oil reservoir, separa-
tion chamber and all piping and tub-
ing may be at high temperature during
and after operation.
LOCATION (FIGURE 2–1) – The compressor should
be installed where it is protected from rain, snow and
freezing temperatures, in a clean, well–lighted, well–
ventilated area with ample space all around for mainte-
nance. Select a location that provides a cool, clean, dry
source of air. In some cases it may be necessary to
install the air filter at some distance from the compres-
sor to obtain proper air supply.
Air–Cooled Unit – A combination oil/aftercooler is
supplied as standard equipment on all air–cooled units.
The air–cooled unit with the standard enclosure re-
quires sufficient flow for the compressor oil/aftercooling
system and electric motor cooling (FIGURE 2–2). Air
is drawn into the unit at the motor side of the enclosure
and is exhausted at the cooler side. Do not block the air
flow to and from the unit. Allow three and one half
(3–1/2) feet (1.1M) to the nearest obstruction on the
starter end and control box end of the unit. Allow two
(2) feet (.6M) to the nearest obstruction above and on
other sides of unit. For continuous efficiency, oil cooler
cores must be periodically cleaned with either vacuum
or compressed air. If wet cleaning is required, shield
motor and spray on a mild soap solution and flush with
clean water.
For aluminum oil coolers, do not use
any cleaning solution that is not com-
patible with aluminum. Use of improp-
er solution may result in damage to
the cooler.
