not be adjusted. However the blower, motor and drives
should periodically be checked for tightness and align-

blower wheel to the shafts to make sure they are secure.
Make sure the setscrews locking down the adjustable
ange on the motor sheave are secure.
The factory setting for the drive on the condenser fan
motor is 4 and turns open from the closed position.
