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. The compressor
unit and driver must be aligned after installation as
specified in the Operator's Manual. No piping loads
shall be transmitted to the compressor at the exter-
nal connections.
4.2 VENTILATION AND COOLING
For air-cooled compressors, select a location to per-
mit sufficient unobstructed air flowing in and out to
the compressor to keep the operating temperature
stable. The minimum distance that the compressor
should be from surrounding walls is three (3) feet
(914mm). To prevent excessive ambient tempera-
ture rise, it is imperative to provide adequate ventila-
tion.
For water-cooled compressors, it is necessary to
check the cooling water supply. The water system
must be capable of supplying the following flows:
WATER TEMP.

(water pressure should be between
25 and 75 PSIG (172 and 517kPa).
For water-cooled compressors, it is necessary to
check cooling water supply. The proper water flow
as indicated in the table above, must be maintained
at all times. These figures apply to a compressor
running at full load with an aftercooler. For cooler
water or a partially loaded compressor, slightly less
water is required. However, for hotter water the flow
requirements are significantly greater.
The table below indicates the ventilation require-
ments necessary to keep the compressor running at
a normal operating temperature. The fan air require-
ment is the volume of air which must flow through

the compressor for proper ventilation. The specified
heat rejection requirement is the amount of heat that
is radiated by the compressor. This heat must be re-
moved to assure a normal operating temperature.
With air-cooled compressors it is possible to use this
heat for space heating, providing no additional pres-
sure drop is created across the fan. Consult a Sullair
office for assistance in utilizing this heat.
DO NOT install a water-cooled or an air-cooled/af-
tercooled compressor where it will be exposed to
temperature less than 32ºF(0ºC).
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 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
No coupling alignment is required.
4.5 FLUID LEVEL CHECK
The 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 near the sump. If
the sump is properly filled, the fluid level should be
visible in the sight glass.
4.6 ELECTRICAL PREPARATION
Interior electrical wiring is performed at the factory.
Required customer wiring is minimal, but should be
done be a qualified electrician in compliance with
OSHA, National Electrical Code, and any other ap-
plicable local electrical code concerning isolation
switches, fuse disconnects, etc. Sullair provides a
wiring diagram for use by the installer.
A few electrical checks should be made to help as-
sure that the first start-up will be trouble free.
Lethal shock hazard inside.
Disconnect all power at source, before opening or
servicing.
1. Check incoming voltage. Be sure that the incom-
ing voltage is the same voltage that the compres-
sor was wired for.
