INSTALLATION
GENERAL
— On receipt of the unit, check for any darnage
that may have been incurred
during transit. Report any
damage or missing parts as soon as possible.
A
WARNING
DO
NOT electric weld on the compressor or base; bearings
can be damaged by passage of current through compressor.
A
DANGER
The eyebolts or lugs provided on the motor are for lifting
the motor only and should not be used to lift any
additional weight. A 11eyebolts 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 or personal
injury.
COMPRESSOR UNIT

FIGURE
1-6. — COMPRESSOR
ENCLOSURE
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. If the unit is to be operated in
an enclosed space, provide an adequate inlet and outlet for
cooling
air. Proper
ventilation
MUST
be provided
for
adequate
cooling,
hot air must be exhausted
from
the
enclosure.
Do not block air flow through the cooler. Allow
two (2) feet from the cooler
face to nearest obstruction.
Figure 1-6 is a typical inlet-outlet
air flow arrangement.
FOUNDATION
— The ELECTRA-SCREW
compressor
requires no special foundation,
but should be mounted
on
a smooth, solid surface. Whenever possible, install unit near
level.
Mounting
bolts
are
not
normally
required,
but
are
suggested where convenient.
Installation conditions
such as
piping
rigidity, angle of tilt, or danger of shifting from
outside vibration or moving vehicles may require the use of
mounting
bolts to the floor.
CONDENSATE
EJECTOR
DRAIN
— As an optional
feature, the unit can be equipped
with a condensate ejector
piped to the bottom of the air receiver. The ejector operates
each time the compressor
unloads. The condensate should
be piped
away from the unit to a suitable drain.
AFTERCOOLER
— An aftercooler will provide control of
moisture entering the shop air lines. It will also reduce the
normal low discharge temperature of about 170° F. at 100
PSIG discharge
to near compressor
inlet temperature.
When an aftercooler is used, a moisture separator should be
mounted
between
the
aftercooler
and
'the
auxiliary
air
receiver
or shop
system with a condensate
drain provided
at
the bottom.
For complete
installation and maintenance
instructions on
any
accessory
equipment
refer
to the manufacturer's
bulletin included
in the unit data package.
INLET LINE — Where an inlet line is used between the air
filter and the compressor,
it must be thoroughly cleaned on
the inside
to prevent
dirt or scale from
entering
the
compressor.
If welded construction is used, the line must be
shot blasted and cleaned to remove welding scale. In either
case, the inlet line must be coated internally by galvanizing
or painting with a moisture-
and oil-proof
sealing lacquer.
The inlet line should be at least the full size of the inlet
opening
on the compressor.
Accessibility
for
inlet
air
filter
servicing
must
be
considered
when relocating
the filter from the unit to a
remote
location.
