Blower Motor Rotation
Before placing the blower-dryer into service, check to verify that the
blower motor rotates in the correct direction (arrow in blower housing indicates
correct rotation). Incorrect rotation will result in unacceptable performance.
To check the blower motor's rotation:
Turn the power disconnect switch ON and momentarily activate the blower-dryer.
The main dishwasher must be operating during this procedure.
Be careful not to touch any uninsulated electrical parts that are exposed. If the
blower motor does not rotate in the proper direction, disconnect the electrical power
supply to the machine.
Disconnect the electrical power to the machine and follow
lockout / tagout procedures. There may be multiple circuits. Be sure all circuits
are disconnected.
Reverse any two of the blower motor cable leads at the overload relay using the
lever-type wire connectors. Reconnect the electrical power supply to the machine.
Re-check the blower motor's rotation.
