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. 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.
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, page
9). Air is drawn into the unit above the motor and dis-
charged through the cooler. Do not block the air flow to
and from the unit. Allow three and one half (3–1/2) feet
to the nearest obstruction on the starter end and control
box end of the unit. Allow two (2) feet to the nearest ob-
struction above and on other sides of unit. For continu-
ous 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.
Do not operate machine while the en-
closure panels are not in place. High
temperature shutdowns will occur.
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.
