INSTALLATION
2.1 PARKING OR MOUNTING OF
COMPRESSOR
Park or mount compressor on a level surface, if
possible. If unable to park or locate the compressor
on a level surface position the compressor on a
grade surface which will not allow the compressor to
roll downhill.
DO NOT park or mount compressor on surface
grades exceeding 15 degrees.
The compressor package should be placed on a
surface or foundation capable of supporting 10%
more than only the compressor weight. Make
faudation weight allowance for snow, ice, mud and
stored tools.
No piping loads or moments should be transmitted to
the air and fuel connections provided with the
package.
Park or locate compressor so the wind, if any, will
help carry the exhaust fumes and radiator heat away
from the compressor air inlet openings. The
compressor should not be exposed to excessive dust
from the worksite.
If compressor is equipped with the optional wheel
package, park compressor with the front wheels in a
straight ahead position. Set the parking brakes and
block or chock both sides of all wheels. Disconnect
coupling device, keeping hands and fingers clear of
all pinch points. Raise the drawbar and lock it in the
upright position. Keep feet clear of drawbar at aU
times to avoid crushing accidents while positioning
the drawbar in case it should slip from your hands or
otherwise fall to the ground.
2.2 VENTILATION AND
COOLING
Select a location that allows an unrestricted flow of
free ventilation air through the package,
(approximately 48,000 CFM [1358 m3/min]). The
maximum allowable ambient temperature is 115°F
(46°C). Heat rejection to the surrounding
environment can be up to 32,000 BTU/min.
Avoid any recirculation or ingestion of heated gases.
Compressor and engine/intake is located next to
package controller.
Package discharge (cooling air) is located on top
of package.
Package intake (cooling air) is located on end of
package.
Maintain a 6 ft. (1.8 m) minimum separation between
the package and any surrounding walls.
If ductwork is installed, the total restriction on intake
must not exceed 0.1 inches H20 (25 Pascals). The
total restriction on the outlet must not exceed 0.1
inches H20 (25 Pascals).
Elevation: As with all two-stage Oil-Free
Compressors, package rating must be reduced
above 4000 ft. sea level.
2.3 SERVICE AIR CONDENSATE
PIPING
A shut-off valve is included to isolate the package
from the supply line as required.
No piping loads or moments should be transmitted to
the air connections provided with the package.
Condensate drains shall be connected to a
nonpressurized gravity feed drain. If the compressor
drains are manifolded together, care should be taken
to ensure that this drain is not pressurized when the
machine condensate drains (both automatic or
manual) are in operation.
All condensate should be disposed of in accordance
with local governing laws.
