4.1 GENERAL
Each ES --- 8 Integral Compressor/Dryer is test --- run
at the factory before shipment. Immediately upon
receipt of the equipment, remove the canopy end
panel a nd check t he unit carefully for a ny physical
damage that may have occurred in transit.
If there isanyphysicaldamage ora refrigerantleak,
pleasefilea claimwith theshipper immediatelyand
notifyyourSullairrepresentativeorthefactoryofthe
nature of the damage. The carrier is legally respon-
sibleforanydamages. YourSullairrepresentativeor
Sullair Corporation will assist in any way possible to
rectify problems.
After youare a ssured that the unithas sustained no
shipping damage, the compressor/dryer is ready
for installation.
4.2 MOUNTING OF INTEGRAL COMPRESSOR/
DRYER
The unit should be installed in an area that is clean
and dry, allowing sufficient space on all sides for
routine maintenance and service. The unit should
be shielded from the weather elements, and in an
area with an ambient temperature above 65_F
(18_C) and notmorethan 100_F(38_C). Occasion-
al operation at ambient temperature up to120_F
(49_C) will not damage the compressor/dryer, but
willaffect the capacityand dewpoint. Temperatures
below35_F(2_C)cancausefreeze---upsoft hecon-
densate drains. If prolonged periods below 35_F
(2_C) are expected, a heat source for these areas
will have to be provided.
CAUTION
!
ES---8 integral compressor/dr yers are notequipped
with a refrigerant compressor crankcase heater.
Installation of these compressor/dryers in areas
with ambient temperatures below 65_F(18_C) can
result in compressor damage.
Sufficient ventilation must be provided to maintain
acceptableambient temperature for efficientopera-
tion. A total ventilation of 1800 CFM (50.97 M
3
/min)
is required for the compressor with integral dryer.
NOTE
A foundation or mounting capable of supporting
the weight of the machine, and rigid en ough to
maintain the frame level, is required.
4.3 COMPRESSOR/DRYER PIPING
WARNING
!
Dryer system contains HCFC---22, a substance that
harms the public health and environment by de -
stroying the ozone in the upper atmosphere.
WARNING
!
“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 32 should not be used with PVC piping sys-
tems. It may affect the bond atcemented joints.Cer-
tain other plastic materials may also be affected.
(I) Plastic Pipe Institute, Recommendation B,
Adopted January 19, 1972.
Compressed a ir piping should be at least of equal
size to that furnished on the outlet of the compres-
sor/dryer. Larger pipes reduced to the inlet/outlet
pipe size may be used.
Make sure, w hen piping is connected, that undue
stress is not applied on the compressor/dryer fit-
tings.
Drainlinesshouldbe sloped adequatelyto drain by
gravity any water accumulated after separation.
Drains must be connected directly to a proper dis-
posal s ystem.

4.5 COMPRESSOR 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 t he fluid level sight tube lo-
catedontheendbell.
If the sump is properly filled, the fluid level should
cover 1/4 to 1/2 of the levelrange during operation.
Withthecompressorshutdown,thelevelshouldbe
3/4 of the sight tube. DO NOT overfill.
4.6 MOTOR ROTATION CHECK
Aftertheelectricalw iringhas beendone,itisneces -
sary to check t he direction of t he 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 motor for a very short time. When looking at the
motorfromt he controlpanelside,viewthecoupling
by looking through the air inlet duct on the lower
side of the adapter fan housing. The coupling
shouldbe turningclockwise.I fthe reversedrotation
