Minimum Air Flow* For Compressor
And Cooling (Cubic Feet/Minute)
All Models
* 80 F Inlet Air
FIGURE 2–2
FOUNDATION – The Electra–Screw
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
Mounting bolts are not normally required. However,
installation conditions such as piping rigidity, angle of
tilt, or danger of shifting from outside vibration or mov-
ing vehicles may require the use of mounting bolts and
shims to provide uniform support for the base. Belt
alignment and tension should be checked after installa-
tion. (For information on belt alignment and tension,
see page 31.)
OIL RESERVOIR DRAIN – The oil drain is piped from
the bottom of the reservoir to the side of the frame. This
drain is approximately 2 inches above the floor level. If
this is not sufficient to conveniently drain the oil some
other methods of providing drain are:
1.
Air Cooled
3000 cfm
compressor re-
o
sidewise.
2.
3.
ENCLOSURE – The compressor, electric motor, oil
cooler and aftercooler are mounted inside the enclo-
sure.
Service panels are provided for maintenance access.
Be sure to allow enough space around the unit for the
doors to be removed.
Any of the enclosure panels may be removed by open-
ing the latch and lifting it up slightly.

Elevate the compressor unit on a suitable struc-
ture to obtain the desired drain height.
If the compressor unit base is raised
above floor level, the space between
the floor and the base bottom must be
closed with solid material all around
to prevent recirculation of hot air from
the oil cooler end and over tempera-
ture operation.
Construct an oil sump or trough below the floor
level and pump or bail the drained oil.
Pump oil from the reservoir filler opening or drain
to a container.
