Maintenance

!WARNING

Hazardous Service Procedures!

The maintenance and trouble- shooting procedures recommend- ed in this section of the manual could result in exposure to electri- cal, mechanical or other potential safety hazards. Always refer to the safety warnings provided throughout this manual concern- ing these procedures. When possi- ble, disconnect all electrical power including remote discon- nects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be in- advertently energized. When nec- essary to work with live electrical components, have a qualified li- censed electrician or other indi- vidual who has been trained in handling live electrical compo- nents perform these tasks. Failure to follow all of the recommended safety warnings provided, could result in death or serious injury.

Access to Fanboard & Motor

The unit ventilator fan board can be re- moved for service to the blower motor and fan wheels. The fan board must also be removed for easier access to the unit coils for cleaning and mainte- nance. Utilize the following steps for proper removal of the fanboard.

1Turn off power to the unit and re- move the front panel.

2Disconnect P-trap from drain pan.

3Disconnect fan plug.

4Slide fan board by pulling deck forward, Figure 17.

CAUTION

Equipment Damage!

Support the fanboard to prevent the deck from sliding too far for- ward and falling out of the unit.

Failure to do so may cause equip- ment damage.

5When reinstalling, use the same steps in reverse order.

Motor

The fan motor is a permanent split ca- pacitor type motor with voltage specif- ic power. See Table E1 through E3 for electrical performance and motor volt- age.

6Complete steps for removal of fan board.

7Disconnect the motor ground wire.

8Using a 7/16” Allen wrench, loos- en the coupling on the fan shaft.

9Loosen the screw on the motor clamp until it allow the motor to be lifted off the base, Figure 18.

10Lift the motor and pull forward until fan shaft separates from the motor, Figure 19.

11Attach new motor to fan shaft and reverse steps to complete in- stallation.
