INSTALLATION OF THE COMPRESSOR
A) After the work has been completed, reinstall
the compressor on the base or C-ange adapter
(dependent upon compressor model).
B) On the units, replace the shims under the com-
pressor feet. Check for a soft foot. This is ac-
complished by tightening down three of the hold
down bolts and checking the clearance under the
fourth compressor foot. If there is clearance, add
the appropriate amount of shims. Tighten down
the fourth bolt and loosen either adjacent bolt
and check again for clearance, adding shims ac-
cordingly. Align the compressor and motor.
On compressors the discharge elbow should
be tightened on the separator rst, before the
compressor manifold ange is tightened. This
should be done to prevent compressor to motor
misalignment.
Replace all electrical, gas and oil connections
removed when servicing the compressor.
LEAK CHECKING UNIT
Note: Unit can be leak checked before evacuation.
CAUTION
Slowly pressurize the unit from the discharge side of the
compressor. Pressurizing the compressor from the suc-
tion side may cause rotation of the compressor without
oil supply, which could lead to internal damage.
A) Use a vacuum pump to evacuate the unit.
B) Break the vacuum on the unit using dry nitrogen
and check for leaks. Concentrate on areas where
work was done.
C) If no leaks are found, the unit can be returned to
service.
