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
Lift compressor unit by base only. Do
not use other places such as the mo-
tor, compressor or discharge man-
ifold 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 in a clean, well–lighted, well–ventilated
area with ample space all around for maintenance. Se-
lect 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 compressor to obtain
a proper air supply.
The compressor unit requires electric motor cooling air
as well as air to the compressor inlet. Proper ventilation
MUST be provided (FIGURE 2–2); hot air must be ex-
hausted from compressor operating area. A typical in-
let–outlet air flow arrangement is show in FIGURE 2–1.
If the air–cooled oil cooler module is to be installed at
a location remote from the compressor unit, be sure
that adequate ventilation is provided, FIGURE 2–2.
Hot air must be exhausted from the oil cooler area.
Do not block the air flow to and from the unit. Allow
3–1/2 feet to the nearest obstruction on the control box
side of the unit and 3 feet on all other sides.

VENTILATION – The unit, whether air– or water–
cooled, requires sufficient air flow, FIGURE 2–2, for
electric motor cooling. Air is drawn into the back and
front of motor and is discharged out the sides. Do not
block air flow to and from the unit.
FOUNDATION – The Electra–Saver compressor re-
quires no special foundation but should be mounted on
a smooth, solid surface of sufficient strength to support
the weight of the unit. Whenever possible, install the
