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 compres-
sor in alignment is required. The compressor frame
must be leveled and secured with foundation bolts,
and full uniform contact must be maintained
between the frame and foundation. It is recom-
mended that the frame be grouted to the founda-
tion. The compressor unit and driver must be
aligned after installation as specified in the
Operator’s Manual. No piping loads shall be trans-
mitted to the compressor or the cooling package at
the external connections.
4.2 VENTILATION AND COOLING
For air-cooled compressors, select a location to
permit sufficient unobstructed air to flow in and out
of the compressor cooling package to keep the
operating temperature stable. The minimum dis-
tance that the compressor should be from sur-
rounding walls is four (4) feet (122 cm). 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-HP/KW WATER FLOW (GPM)
LS-32 400HP/299KW 87
Water flow requirements are based on 80°F to 85°F
(27°C to 29°C) water inlet temperature.
Recommended water pressure range is 40 to 75
psig (2.8 to 5.2 bar). Water flow rates will vary with
operating conditions. For rates based on criteria
other than that listed, consult your local Sullair
representative.
Table 4-1 Ventilation Requirements below indicates
the ventilation requirements necessary to keep the
compressor running at a normal operating temper-
ature. The fan air requirement is the volume of air
which must flow through the compressor and/or
cooling package for proper ventilation. The speci-
fied heat rejection requirement is the amount of
heat that is radiated by the compressor. This heat
must be removed to assure a normal operating tem-
perature. With air-cooled compressors it is possible
to use this heat for space heating, providing exces-
sive 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 tem-
perature less than 32°F(0°C).
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 a compressor from the service line if
required. 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. After the compressor package has been
mounted to a foundation, 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 prop-
er 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 1/2 of the upper sight glass when the
compressor is shutdown. When the oil level falls
below the center of the lower sight glass, fluid must
be added.
4.6 ELECTRICAL PREPARATION
Interior electrical wiring is performed at the factory.
Required customer wiring is minimal, but should be
by a qualified electrician in compliance with OSHA,
National Electrical Code, and any other applicable
state or local electrical code concerning isolation
switches, fuse disconnects, etc. Sullair provides a
