Monthly Maintenance

WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
Before completing the following checks, turn the unit OFF
and lock the main power disconnect switch open.

Filters

Inspect the return air filters. Clean or replace them if
necessary. Refer to the table below for filter information.
Table 74. Filters
Unit Model Quantity
TC, TE, YC*330 - 420 16
TC, TE, YC*480 & 600 17
* Filter dimensions are actual. Nominal filter size is 16 x 20.

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.
• 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.

• 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.
• 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. These bearing are considered
permanently lubricated for normal operation. For
severe dirty applications, if relubrication becomes
necessary, use a lithium based grease. See
p. 99 for recommended greases.
Important: The bearings are manufactured using a
special synthetic lithium based grease
designed for long life and minimum relube
intervals. Over lubrication can be just as
harmful as not enough.
Use a hand grease gun to lubricate these bearings; add
grease until a light bead appears all around the seal. Do
not over lubricate!
After greasing the bearings, check the setscrews to ensure
that the shaft is held securely. Make sure that all bearing
braces are tight.
• Check the supply fan belt(s). If the belts are frayed or
worn, replace them.
• Check the condition of the gasket around the control
panel doors. These gaskets must fit correctly and be in
good condition to prevent water leakage.
• Verify that all 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.)
