INSTALLATION
Section 4
4.1 COMPRESSOR MOUNTING -
SUPPORT AND LOCATION
The compressor must have a stable firm foundation,
or mounting structure that is rigid enough to keep the
compressor frame level, and maintain the alignment
of the compressor and motor. Tie-down bolts of
sufficient size must be used to ensure that the
compressor frame is firmly anchored to its
foundation. Rubber, cork, or other pliable materials
can be inserted between the foundation and
compressor frame to provide a uniform contact
surface.
• Use flex connectors to prevent piping loads
from being transmitted to the compressor.
• National and local electrical codes specify-
ing the required clearances for the area
around the electrical panel must be com-
plied with.
• Ensure the lighting at the compressor’s
location is sufficient for safe operation and
maintenance.
• The compressor’s location should be one
that allows access for maintenance vehi-
cles and lifting equipment.
• The clearances around the compressor
should permit easy access to all compres-
sor components.
• Walls and ceilings with soft or porous sur-
faces absorb sound and reduce ambient
noise levels. Hard surfaces reflect noise
and have little effect on ambient noise lev-
els.
• Water-cooled compressors must be located
where a cooling water supply and drainage
are available.
4.2 VENTILATION AND
COOLING
AIR-COOLED COMPRESSORS
• Air-cooled compressors require a three foot
(one meter) clearance around their perime-
ter.
• The location should be free from standing
water.
• Clean air should be supplied to the com-
pressor, free from exhaust and paint
fumes, dust, metal particles, or caustic
chemical vapors.
• Hot exhaust air should be vented out of the
area to prevent its recirculation back into
the compressor’s cooling system.
• Ducting or some other means must be used
to ensure that hot exhaust air is vented
away from the compressor if the compres-
sor’s housing has minimal overhead clear-
ance.
NOTE
Do not install compressors where the machine
will be exposed to temperatures lower than 32°F
(0°C). Contact Sullair Customer Care regarding
operation in sub-freezing temperatures.
NOTE
Compressors operated in environments where
ambient temperatures average above 104°F
(40°C) must be equipped with the high-ambient
option.
NOTE
Systems using both reciprocating and rotary
screw compressors must isolate the two types
from each other through the use of a common
receiver tank. Air lines from each individual
compressor should be connected directly to the
common receiver tank.
NOTE
Remove the red shipping straps before operating
the drive assembly.
