Filters
Inspect the return air filters. Clean or replace them if
necessary. Refer to the unit Service Facts for filter
information.
Condensate Overflow Switch
During maintenance, the switch float (black ring) must
be checked to ensure free movement up and down.
Cooling Season
☐ Check the unit’s drain pans and condensate piping
to ensure that there are no blockages.
☐ Inspect the evaporator and condenser coils for dirt,
bent fins, etc. If the coils appear dirty, clean them
according to the instructions described in “Coil
Cleaning” later in this section.
☐ Manually rotate the condenser fans to ensure free
movement and check motor bearings for wear.
Verify that all of the fan mounting hardware is tight.
☐ Inspect the F/A-R/A damper hinges and pins to
ensure that all moving parts are securely mounted.
Keep the blades clean as necessary.

☐ Verify that all damper linkages move freely;
lubricate with white grease, if necessary.
☐ Check supply fan motor bearings; repair or replace
the motor as necessary.
☐ Check the fan shaft bearings for wear. Replace the
bearings as necessary.
☐ Check the supply fan belt(s). If the belts are frayed
or worn, replace them. Refer to the “Fan Belt
Adjustment-Belt Drive Units,” p. 26 for belt
replacement and adjustments.
☐ Verify that all wire terminal connections are tight.
☐ Remove any corrosion present on the exterior
surfaces of the unit and repaint these areas.
☐ Generally inspect the unit for unusual conditions (e.
g., loose access panels, leaking piping connections,
etc.)
