2. The area should be free of excessive dust, toxic or
flammable gases, moisture and direct sunlight.
3. Never install the compressor where the ambient
temperature is higher than 104°F or where humidity is high.
High humidity will cause electrical short circuit and rusting
of components.
4. Clearance must allow for safe, effective inspection and
maintenance.
A minimum of 24 inches of
clearance for sides, 40 inch
clearance from the top is required.
5. If necessary, use metal shims or leveling pads to level the
compressor. Never use wood to shim the compressor.
PRECAUTIONS DURING TRANSPORTATION AND
MOVEMENT
TRANSPORTATION BY FORKLIFT
Use openings for forklift under both sides of the unit.
TRANSPORTATION BY CRANE
Use openings at bottom of the unit to life up by cable, lifting
straps etc. Make sure all lifting devices are rated for the
maximum load.
Avoid damaging the panel with
tips of forklift.
Be sure to use pads in order to
protect the panels.
VENTILATION
1. If the scroll compressor is located in a totally enclosed
room, an exhaust fan with access to outside air must be
installed.
2. Never restrict the cooling fan exhaust air or the intake
cooling air.
3. Vent the exhaust air outside to prevent the compressor
from operating at high temperatures and shutting down.
4. Never locate the compressor where hot exhaust air from
other heat generating units may be pulled into the unit.
SUGGESTED VENTILATION SYSTEM
The temperature rise in the room must be kept to a maximum
of 10 F. The BTU capacity of the vent system should be sized
for the full operating HP rating of the compressor. Suggested
fan capacity at 0 static pressure is shown below. If static
pressure is higher, the fan capacity should be increased.
Chart 1
An exhaust duct may be installed to capture the warm air
exiting the compressor enclosure. The opening of the exhaust
duct should be about 6 inches larger on each side than the
vent openings on the compressor top panel. The duct should
not obstruct removal of the top panel for service. Leave be-
tween 8 and 12 inches of clearance. The cfm capacity of the
cooling fan should be increased to compensate for duct flow
losses.
INSTALLATION SITE
1. The scroll compressor must be located in a clean, well lit
and well ventilated area. A contaminated area can clog the
intake filter and / or intake metal mesh.
