General; Mounting Of Integral Compressor/Dryer; Compressor/Dryer Piping; Compressor Coupling Alignment Check - Sullair ES-8 Operator's Manual And Parts List

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 and check the unit carefully for any physical
damage that may have occurred in transit.
If there is any physical damage or a refrigerant leak,
please file a claim with the shipper immediately and
notify your Sullair representative or the factory of the
nature of the damage. The carrier is legally respon-
sible for any damages. Your Sullair representative or
Sullair Corporation will assist in any way possible to
rectify problems.
After you are assured that the unit has 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 not more than 100_F (38_C). Occasion-
al operation at ambient temperature up to120_F
(49_C) will not damage the compressor/dryer, but
will affect the capacity and dewpoint. Temperatures
below 35_F (2_C) can cause freeze---ups of the con-
densate drains. If prolonged periods below 35_F
(2_C) are expected, a heat source for these areas
will have to be provided.
ES---8 integral compressor/dryers are not equipped
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
acceptable ambient temperature for efficient opera-
tion. A total ventilation of 1800 CFM (50.97 M
is required for the compressor with integral dryer.
A foundation or mounting capable of supporting
the weight of the machine, and rigid enough to
maintain the frame level, is required.

4.3 COMPRESSOR/DRYER PIPING

Dryer system contains HCFC ---22, a substance that
harms the public health and environment by de-
stroying the ozone in the upper atmosphere.
CAUTION
!
NOTE
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 at cemented joints. Cer-
tain other plastic materials may also be affected.
(I) Plastic Pipe Institute, Recommendation B,
Adopted January 19, 1972.
Compressed air 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, when piping is connected, that undue
stress is not applied on the compressor/dryer fit-
tings.
Drain lines should be sloped adequately to drain by
gravity any water accumulated after separation.
Drains must be connected directly to a proper dis-
posal system.

4.4 COMPRESSOR COUPLING ALIGNMENT CHECK

With the compressor unit directly flange---mounted
to its drive, the coupling supplied with the compres-
sor is always properly aligned for operation. Howev-
er, we recommend that you re---check the coupling
gap before start ---up or when handling the unit.
1.5 to 3mm axial clearance should be maintained for
the coupling gap. See Drive Coupling Installation in-
formation in Section 9, Compressor Maintenance
and Troubleshooting.

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 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
/min)
3/4 of the sight tube. DO NOT overfill.

4.6 MOTOR ROTATION 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)
and (STOP) "O" pads. This action will bump start
the motor 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 ex-
change any two of the three power input leads, then
re---check rotation. A "Direction of Rotation" plate is
located on the motor and cooler shroud to show
