INSTALLATION
4.1 MOUNTING OF COMPRESSOR
A suitable foundation or fabricated support must be
established to support the compressor. It should be rigid
enough to keep the compressor frame level and
maintain alignment of the compressor and motor. Tie-
down bolts of sufficient size must be used to provide
uniform contact between the foundation and the
compressor frame. Materials such as rubber or cork can
be used to provide uniform contact between the
foundation and compressor frame.
• Piping loads must be eliminated through the use of
flex connectors or other systems which prevent
piping loads from being transmitted to the
compressor.
• Special consideration should be made to meet
national and local electrical codes for the required
space around and in front of the electrical panel.
Lighting should be provided for future service
requirements.
• Accessibility for fork lift trucks, overhead cranes and
maintenance vehicles should be given careful
consideration in order to provide any maintenance
that may be required. Adequate space around the
unit should be provided for access to all
components of the compressor.
• Softer surfaces in walls or ceilings will absorb sound
and minimize ambient noise levels. Harder,
reflective surfaces will increase ambient noise
levels.
• Water-cooled compressors must have provisions
for cooling water supply and drainage available.
4.2 VENTILATION AND COOLING
AIR-COOLED COMPRESSORS
• An area with adequate space must be provided for
the compressor and its components. Air-cooled
compressors require a minimum of 3 feet (1 meter)
around the perimeter of the compressor.
• The location should be free from standing water and
allow access to clean air that is free from exhaust
and paint fumes, dust, metal filings or caustic
chemicals.
• Cooling air should be removed from the area in
order to prevent the re-introduction of heated
exhaust air back into the compressor’s cooling
system.
• Reduced headroom above the compressor will
require that cooling air be either ducted or in some
way deflected away from the compressor.
Inadequate ventilation will result in higher ambient
operating temperatures.
NOTE
Ambient temperatures above 104°F (40°C)
require that the high ambient option is
specified for the compressor.

NOTE
Systems that employ both a conventional
reciprocating compressor and a screw-
type axial compressor must be isolated
from each other by use of a common
receiver tank. Individual airlines from
each compressor should be piped to the
common receiver tank.

NOTE
Shipping straps are painted red in order to
help identify them for removal. Be sure to
remove them prior to operation of the
drive assembly.
