4.1 MOUNTING OF COMPRESSOR
A foundation or mounting capable of supporting
the weight of the compressor, and rigid enough to
maintain the compressor frame level and the com-
pressor in alignment, is required. The compressor
frame must beleveled andsecured withfoundation
bolts, and full uniform contact must be maintained
between the frame and foundation. 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 flowingin and out
to the compressor to keep the operating tempera-
ture stable. The minimum distance that the com-
pressor should be from surrounding walls is three
(3) feet (0.9 m). To prevent excessive ambient tem-
perature rise, it is imperative to provide adequate
ventilation.
F or water---cooled compressors, it is necessary to
check the cooling water supply. The water system
must be capable of supplying the following flows:

TABLE 1 --- WATER FLOW REQUIREMENTS
The pr oper water flow as indic a ted in Table 1 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 great-
er.
Ta bl e 2 shows the ventil ation r equir ements nec es -
sary to keep the compressor running at a normal
operating temperature. The fan air requirement is
the volume ofair which must flowthrough the com-
pressor 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
pressure drop is created across the fan. Consult a
Sullair office for assistance in utilizing this heat.

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 the 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.
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.” (

4.4 COUPLING ALIGNMENT CHECK
No coupling alignment is required.
4.5 FLUID LEVEL C HECK
The air compressor isalso supplied withtheproper
amount of fluid. However, it is necessary to check
thefluidlevel atinstallation. The level is checkedby
looking at the sight glass located near the sump. If
the sump is properly filled, the fluid level should be
at the normal reading.
4.6 ELECTRICAL PREPARATION
Interior electrical wiring is performed at the factory.
Required customer wiring is minimal, but should
be done by a qualified electrician in compliance
withOSHA,National Electrical Code, and anyother
