Monthly Maintenance

Before completing the following checks, turn the unit OFF
and lock the main power disconnect switch open.

WARNING

Hazardous Voltage!

Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.

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.

WARNING

Rotating Components!

Failure to disconnect power before servicing
could result in rotating components cutting and
slashing technician which could result in death or
serious injury.
During installation, testing, servicing and
troubleshooting of this product it may be
necessary to work with live and exposed rotating
components. Have a qualified or licensed service
individual who has been properly trained in
handling exposed rotating components, perform
these tasks.

NOTICE

Equipment Damage!

Forcibly turning the motor shaft can damage the
gear train and motor beyond repair.
Never turn the motor shaft by hand or with a
wrench.

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. 39

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.)

Make sure that all retaining screws are reinstalled in the
unit access panels once these checks are complete.

With the unit running, check and record the following:
