SECTION 2
INSTALLATION
GENERAL— On receipt of the unit check for any damage
that may have been incurred during transit Report any
damage or missing parts as soon as possible
CAUTION
DO NOT electric weld on the compressor or base bear-
ings 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 dis-
charge manifold and piping as lifting points.
~DANGER
The eyebolts or lugs provided on the motor are for lifting
the motor only and should not be used to lift any addi
tional weight All eyebolts must be securely tightened
When lifting the motor the lifting angle must not ex-
ceed 15 degrees Failure to observe this warning may
result in damage or personal injury.
Physical size and weight of unit may allow use of tow
motors Unit may also be moved into location by rolling
on bars

FIGURE 1-2. – TYPICAL COMPRESSOR ROOM
LOCATION — The compressor should be installed in a
clean, well-lighted, well-ventilated area with ample space
all around for maintenance. 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
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 exhausted from
the compressor operating area A typical inlet-outlet air
flow arrangement is shown in Figure 1-2.
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

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 II
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 unit near
level Temporary installation may be made at a maximum
of 10° angle lengthwise or 30" sidewise.
Mounting bolts are not normally required However, in
stallation conditions such as piping rigidity, angle of tilt
or danger of shifting from outside vibrations or moving
vehicles may require the use of mounting bolts to the
foundation
OIL RESERVOIR dRAIN (Figure 3-1) — The oil res
ervoir drain valve is located near the center of the oil
reservoir just below the separator tower. The drain valve
is approximately 4-1/2 inches from the floor level If this
height is not sufficient to conveniently drain the oil some
other methods of providing oil drain are
1. Elevate the compressor unit on the foundation to
obtain the desired drain height
2. Construct an oil sump or trough below the floor level
and pump or bail the drained oil
3. Pump oil from the reservoir filler opening or res
ervoir drain to a container.
ACOUSTIC ENCLOSURE — The
Electra-Saver 1P
unit is
furnished with an acoustic enclosure over the compressor
