Mounting Of Compressor; Ventilation And Cooling; Service Air Piping - Sullair LS20TS Operator's Manual And Parts List

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 this
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 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 4 feet/1.22m.
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 flow rate as listed in
Table 4A - Water Cooling Supply
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 cri-
teria other than that listed, consult your local
Sullair representative.

Table 4B- Ventilation Requirements
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 for proper
ventilation. The specified heat rejection requirement
is the amount of heat that is radiated by the com-
pressor. This heat must be removed to assure a
normal operating temperature. With air-cooled com-
pressors 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 tem-
perature less than 32ºF(0ºC).
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.
