2.1 LOCATION OF COMPRESSOR
The ES-8 Series compressor package may be
placed on any level surface able to support its
weight. The unit is mounted on vibration mounts and
can be bolted to a fixed mounting surface to avoid
the possibility of externally applied forces or vibra-
tion which would disturb the piping or wiring.
2.2 VENTILATION AND COOLING
Select a location to permit sufficient unobstructed
air flow in and out of the compressor to keep the op-
erating temperature stable. The minimum distance
that the machine should be from surrounding walls
and ceiling is what is needed for service and three
(3) feet (0.91m) or more from the compressor fluid
cooler.
2.3 SERVICE AIR PIPING
Service air piping should be installed as shown in
Figure 2-1. 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.

"The Plastic Pipe Institute recommends against the
use of thermoplastic 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 sys-
tems. It may affect the bond at cemented joints. Cer-
tain other plastic materials may also be affected.

Adopted January 19, 1972.
2.4 COUPLING ALIGNMENT CHECK
With the compressor unit directly flange-mounted to
Figure 2-1 Service Air Piping
WARNING
its drive, the coupling supplied with the compressor
is always properly aligned for operation. However,
we recommend that you re-check the coupling gap
before start-up or when handling the unit. a 1.5 to
3mm axial clearance should be maintained for the
coupling gap.
2.5 FLUID LEVEL CHECK
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 tube lo-
cated on the end bell.
If the sump is properly filled, the fluid level should
cover 1/4 to 1/2 of the level range during operation.
With the compressor shut down, the level should be
3/4 of the sight tube. DO NOT overfill.
2.6 MOTOR ROTATION DIRECTION CHECK
After the electrical wiring has been done, it is neces-
sary to check the direction of the motor rotation.
Pull out the EMERGENCY STOP button and press
once, quickly and in succession, the (START) I and
(STOP) O pads. This action will bump start the mo-
tor for a very short time. When looking at the motor
from the control panel side, view the coupling by
looking through the air inlet duct on the lower side of
the adapter fan housing. The coupling should be
turning clockwise. If the reversed rotation is noted,
disconnect the power to the starter and exchange
any two of the three power input leads, then re-
check rotation. A "Direction of Rotation" decal is lo-
cated on the motor and cooler shroud to show prop-
er motor/compressor rotation.
2.7 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
