[ ] 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 bear-
ings as necessary. These bearing are considered perma-
nently lubricated for normal operation. For severe dirty ap-
plications, if relubrication becomes necessary, use a
lithium based grease. See Table 27 for recommended
greases.
Note: 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.

Monthly Maintenance
Before completing the following checks, turn the unit OFF
and lock the main power disconnect switch open.
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote discon-
nects 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.
Filters
[ ] Inspect the return air filters. Clean or replace them if nec-
essary. Refer to the Table below for filter information.
Unit Quantity Filter Dimension

TC, TE, YC*330 - 420 16 15½ X 19½ X 2*
TC, TE, YC*480 & 600 17 15½ X 19½ X 2*
* Filter dimensions are actual. Nominal filter size
is 16 x 20.
Cooling Season
[ ] Check the unit’s drain pans and condensate piping to en-
sure 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 move-
ment and check motor bearings for wear. Verify that all of
the fan mounting hardware is tight.
