INSTALLATION
GENERAL - On receipt of unit, check for any damage
that may have been incurred during transit. RepoRtany
damage or missing parts as soon as possible.
~CAUTION
Do not electric weld on the compressor
or base; bearings can be damaged by
passage of current.
LIFTING UNIT - Proper lifting and/or transporting
methods must be used to prevent damage.
~CAUTION
Lift compressor unit by base only. Do
not use other places such as enclosure,
motor, compressor oil discharge
manifold and piping as lifting points.
~DANGER
I
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 warn-
ing may result in damage to equipment
or personal injury.
Lifting slots are provided in the base for towmotor use.
Unit may also be moved into location by rolling on bars.
LOCATION - The compressor should be installed where
it is protected from rain, snow and freezing tempera-
tures, in a clean, well-lighted, well-ventilated area with
ample space all around for maintenance. Select a loca-
tion 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 compressor to obtain proper air supp-
ly.
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 requires
sufficient flow, Figure 2-2, for the compressor oil/after-
cooling system and electric motor cooling. Air is drawn
into the unit at the motor side of the enclosure and is
exhausted at the oil cooler side. Do not block the airflow
to and from the unit. Allow three (3) feet to the nearest
obstruction on the starter end and control box end of the
unit. Allow two (2) feet 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. - -
~WARNING
For aluminum oil coolers, do not use
any cleaning solution that is not com-
patible with aluminum. Use of improper
solution may result in damage to
cooler.
FOUNDATION - The Electra-Screw@ comPressor re-
quires no special foundation, but should be mounted on
a smooth, solid surface. Whenever possible install the
unit near level. Temporary installation may be made at a
maximum 10° angle lengthwise or 10° sidewise.
Mounting bolts are not normally required. However, in-
stallation conditions such as piping rigidity, angle of tilt,
