4.8 MOTOR ROTATION
DIRECTION CHECK
Motor rotation check must be done at compressor
start-up after the wiring has been installed. The
compressor can be damaged if it runs in the wrong
direction for more than a few seconds. Motor rotation
can be viewed through the opening in the drive
adapter housing. Pull out the EMERGENCY STOP
button and press once, quickly and in succession,
the
(START) and (STOP) pads. This
action will bump start the motor. When looking from
the motor end opposite the compressor unit, the
shaft should turn clockwise. If reverse rotation
occurs, disconnect the power to the starter and
exchange any two of the three power input leads,
then re-check rotation. A "Direction of Rotation"
nameplate is located on the motor/compressor
adapter to show proper motor/compressor rotation.
Fan motor rotation should also be checked. It should
rotate counter-clockwise when viewing the fan motor
from the backside of the motor.
