PIPING SCHEMATIC OF COOLER
WITH FLANGED CONNECTIONS.
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 the motor and is discharged out the sides. Do
not block air flow to and from the unit.
FOUNDATION – The Electra–Saver
r
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 10
_
angle lengthwise or 30
_
sidewise.
Mounting bolts are not normally required. However,
installation conditions such as piping rigidity, angle of
tilt, or danger of shifting from outside vibrations or mov-
ing vehicles may require the use of mounting bolts to
the foundation.
OIL RESERVOIR DRAIN – (FIGURE 1–5, page 3)
The oil reservoir drain valve is located near the center
of the oil reservoir just below the separator tower. The
drain valve is approximately 5 inches from the floor lev-
el. 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 a suitable struc-
ture 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 drain
to a container.
ACOUSTIC ENCLOSURE – The Electra–Saver unit is
furnished with an acoustic enclosure over the compres-
sor only, as standard equipment. The enclosure re-
duces the normal operating sound of the unit to 90 DBA
or below in free field conditions.
AIR–COOLED OIL COOLER MODULE – The air–
cooled oil cooler is a separate module and may be
mounted remote to the compressor unit.
Ventilation – The oil cooler requires adequate cooling
air flow. Proper ventilation MUST be provided, with hot
air exhausted away from the cooler; take care that hot
air is not recirculated form the exhaust to the inlet side
of the cooler. Cooling air flow direction is from the motor
side through the grille side of the oil cooler. Do not ob-
struct the air flow to or from the cooler. Allow two (2) feet
clearance on all sides of the cooler module. See
FIGURE 2–2, page 8, for cooling air flow require-
ments.
Low Oil Pressure Protection – The standard factory–
installed low oil pressure shutdown switch in the control
box will prevent start–up or shut the unit down if oil
pressure is not established or maintained due to mal-
function in the oil cooler system.
Oil Cooler – Location and General Piping – The oil
cooler module can be mounted in any of several remote
locations; close coupled but not joined to the compres-
sor unit; horizontal remote, located on the same level
as the compressor unit, but some distance away; or
overhead remote, located above level of the compres-
sor unit, as on a roof.
