INSTALLATION

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 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 this Opera-
tor's Manual. No piping loads shall be transmitted
to the compressor or the cooling package at the ex-
ternal connections.

4.2 VENTILATION AND COOLING

For air---cooled compressors, select a location to
permit sufficient unobstructed air flow in and out to
the compressor to keep the operating temperature
stable. The minimum distance that the compressor
should be from surrounding walls is 3 feet/0.9m. 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:
Water flow requirements are based on 80_F to
85_F (27_C to 29_C) water inlet temperature.
Recommended water pressure range is 25 to 75
psig (1.7 to 5.2 bar).

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 for proper ventilation. The
specified heat rejection requirement is the amount
of heat that is radiated by the compressor. This heat
must be removed to assure a normal operating
temperature. With air---cooled compressors it is
possible to use this heat for space heating, provid-
ing excessive pressure drop is not created across
the fan. Consult a Sullair office for assistance in util-
izing this heat.
