Note: The bearings are manufactured using a special synthetic lithium based grease designed for
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.

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
recommended greases.

enough.
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.)
