ES-6 USER MANUAL

4.1 LOCATION OF COMPRESSOR

The ES-6 Series compressor package may be
placed on any level surface able to support its
weight. The unit should be bolted to a fixed
mounting surface to avoid the possibility of
externally applied forces or vibration which would
disturb the piping or wiring.

4.2 VENTILATION AND COOLING

Select a location to permit sufficient unobstructed
air flow in and out of the compressor to keep the
operating temperature
distance that the machine should be from
surrounding walls is what is needed for service and
three (3) feet (0.91m) or more from the fan air
discharge end of the compressor.

4.3 SERVICE AIR PIPING

Service air piping should be installed as shown in
Figure 4-1. A shut-off valve should be installed to
isolate the compressor from the service line. Also
notice that the service line should be equipped with
water legs and condensate drains throughout the
system.
WARNING
"The Plastic Pipe Institute recom-
mends against the use of thermo-
plastic pipe to transport compressed
air or other compressed gases in
exposed above ground locations,
e.g. in exposed plant piping." (I)
Sullube should not be used with PVC
piping systems. It may affect the
bond at cemented joints. Certain
other plastic materials may also be
affected.

dation B, Adopted January 19, 1972.
4.4 FLUID LEVEL CHECK AND
CHANGE PROCEDURE
The Sullair air compressor is equipped with the
proper amount of fluid. However, it is necessary to
check the fluid level at installation. The level is
checked by looking at the fluid level sight glass
located on the end bell. See Figure 2-1.
If the sump is properly filled, the fluid level should
cover 1/4 to 1/2 of the sight glass during operation.
stable. The minimum

DO NOT OVERFILL.
WARNING
Before attempting compressor main-
tenance, disconnect
from power source and lock out
power source. Isolate compressor
from line pressure by closing recom-
mended discharge shutoff valve and
releasing all internal pressure from
compressor.
WARNING
Assure that line pressure gauge on
compressor indicates "ZERO" pres-
sure before any work is done. Failure
to comply may cause injury.
When the compressor fluid is ready to be changed,
the compressor needs to be shutdown with the
power to the compressor disconnected (see
Warning above). Drain

Fluid capacity for the compressor can be found in
Section 3, Specifications
compressor sump is properly filled when the level
on the fluid level sight glass is 3/4 of the sight tube.
During operation, the fluid level should cover 1/4 to
1/2 of the sight glass. DO NOT OVERFILL.
4.5 MOTOR ROTATION DIRECTION
CHECK
After the electrical wiring has been done, it is
necessary to check the direction of motor rotation.
This can be done by jogging the START selector
switch on the front of control center. When looking
at the motor from the cooler end of the compressor
unit, the cooler fan should be turning clockwise. If
the motor is not turning clockwise, disconnect
power to the starter and exchange any two of the
three power input leads, then check rotation.
A direction of rotation decal is located on the motor
shroud, next to the cooler to insure correct motor/
compressor rotation.
4.6 ELECTRICAL PREPARATION
Interior electrical wiring is performed at the factory.
Required customer wiring is minimal, but should be
done by a qualified electrician in compliance with
