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 com-
pressor 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 sur-
face.
• Use flex connectors to prevent piping loads
from being transmitted to the compressor.
• National and local electrical codes specifying
the required clearances for the area around the
electrical panel must be complied with.
• Ensure the lighting at the compressor's location
is sufficient for safe operation and mainte-
nance.
• The compressor's location should be one that
allows access for maintenance vehicles and lift-
ing equipment.
• The clearances around the compressor should
permit easy access to all compressor compo-
nents.
• Walls and ceilings with soft or porous surfaces
absorb sound and reduce ambient noise levels.
Hard surfaces reflect noise and have little effect
on ambient noise levels.

Installation

Subject to EAR, ECCN EAR99 and related export control restrictions.
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.
4.1.1

Outdoor installation (sheltered)

ShopTek packages are equipped with TEFC motors and
have water tight controls that are IP54 rated and are suit-
able for sheltered outdoor installation.
The compressor should be mounted on a concrete pad. If
the pad is not level, the compressor must be mounted in
such a manner that its base or skid is level in relation to
the pad's surface and fully supported.
If the compressor will be exposed to blowing rain or
snow, it should be housed in a covered, four-walled
enclosure.
• Sheltered air-cooled machines must have their
exhaust air vented outside of the enclosure.
• Installations consisting of more than one com-
pressor should be done in such a manner that
each compressor's exhaust is directed away
from the air intakes of other compressors or air
dryers.
• A standard compressor should not be started if
the ambient temperature is 35°F (1.7°C) or
lower.
Compressor must not be operated in sub-freezing
conditions.
