4.1 MOUNTING OF COMPRESSOR
A foundation or mounting capable of supporting the
weight of the compressor, and rigid enough to main-
tain the compressor frame level and the compressor
in alignment is required. The compressor frame
must be leveled and secured with foundation bolts,
and full uniform contact must be maintained be-
tween the frame and foundation. It is recommended
that the frame be grouted to the foundation. The
compressor unit and driver must be aligned after in-
stallation as specified in the Operator’s Manual. No
piping loads shall be transmitted to the compressor
at the external connections.
4.2 VENTILATION AND COOLING
For air---cooled compressors, select a location to
permit sufficient unobstructed air flowing in and out
of the compressor cooling package to keep the op-
erating temperature stable. The minimum distance
that the compressor should be from surrounding
walls is three (3) feet (914mm). To prevent excessive
ambient temperature rise, it is imperative to provide
adequate ventilation.
For water---cooled compressors, it is necessary to
check the cooling water supply. The water system
must be capable of supplying the following flows:
MODEL WATER FLOW (GPM)
32---400HP 87
32---450HP 92
NOTE
Water flow requirements are based on 80_Fto
85_F(27_Cto29_C) water inlet temperature.
Recommended water pressure range is 40 to 75
PSIG (276 to 517kPa).
Water flow rates will vary with operating condi-
tions. For rates based on criteria other than that
listed, consult your local Sullair representative.
The table below indicates the ventilation require-
ments necessary to keep the compressor running
at a normal operating temperature. The fan air re -
quirement is the volume of air which must flow
through the compressor and/or cooling package for
proper ventilation. The specified heat rejection re-
quirement is the amount of heat that is radiated by
the compressor. This heat must be removed to as-
sure a normal operating temperature. With air---
cooled compressors it is possible to use this heat for
space heating, providing excessive pressure drop
is not created across the fan. Consult a Sullair office
for assistance in utilizing this heat.
DO NOT install a water--- cooled or an air---cooled/
aftercooled compressor without adequate freeze
protection where it will be exposed to temperature
less than 32_F(0_C).
4.3 SERVICE AIR PIPING
Service air piping should be installed as shown in
F i g u r e 4 --- 1 . A s h u t --- o f f v a l v e s h o u l d b e i n s t a l l e d t o
isolate a compressor from the service line if re-
quired. Also notice that the service line should be
equipped with water legs and condensate drains
throughout the system.
4.4 COUPLING ALIGNMENT CHECK
In preparation for the factory test, the coupling sup-
plied with your compressor is properly aligned for
operation. However, due to shipping and handling,
it is necessary to recheck the coupling alignment.
Refer to Coupling Alignment procedure explained in
the Maintenance section of this manual.
4.5 FLUID LEVEL CHECK
Your air compressor is also supplied 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 sight glass located on the sump. If the
sump is properly filled, the coolant level should fill
the sight glass.
4.6 FLUID PIPING (AIR-- COOLED ONLY)
To allow depressurization of the cooling package
and connecting piping between the compressor
and the cooling package upon shutdown of the
compressor, a !@2” depressurization line must be in-
stalled between the top of the fluid cooler and the
depressurization valve, which is mounted on the
compressor sump tank. This line must be main-
tained at a higher level than the supply and return
piping for the fluid cooler.
The supply and return piping for the fluid cooler
must be adequately sized to prevent excessive
