INSTALLATION OF THE COMPRESSOR
A) After the work has been completed, reinstall
the compressor on the base or C-fl ange adapter
(dependent upon compressor model).
(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.

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.
