INSTALLATION

The following instruction is provided for proper
installation.
3.1 LOCATION OF COMPRESSOR
The 24KT compressor package may be placed on
any level surface able to support its weight. It is not
necessary to bolt the unit down unless there is a
possibility of externally applied forces or vibration
which could disturb the piping or wiring.
3.2 VENTILATION AND COOLING
For water-cooled machines. it is necessary to
check cooling water supply. The proper water flow
should be 45-55 G.P. M. on 250 HP machines; and
49-65 G.P.M. on 300 HP machines. These figures
apply to 800 F cooling water on a machine running
at full load w ith an aftercooler. For cooler water or a
partially loaded machine. slightly less water is re-
quired; however, for hotter water the flow require-
ments are significantly higher.
For air-cooled compressors, select a location to
permit sufficient unobstructed air-flow in and out of
the compressor t o keep the operating temperature
stable. The minimum distance that the machine
should be from the surrounding walls is three (3)
feet. Hot fan air discharged from the top of the cool-
er package must be prevented from recirculating
back to the cooler cores.
Table 1A --- Ventilation Requirements indicates the
ventilation requirements necessary to keep the ma-
chine running at a normal operating temperature.
The fan air requirement is the volume of air w hich
must flow through the machine for proper ventila-
tion. The specified heat rej ection requirement is the
amount of heat that is radiated by the machine.
This heat must be removed to assure a normal op-
erating temperature. With air-cooled machines it is
possible to use this heat for space heating, provid-
ing no additional pressure drop is created across
the fan. Consult a Sullair office for assistance in uti-
lizing this heat.
