Air Handling Equipment

Before completing the following checks, turn the system control circuit switch 1S2 and 5S1 to the "Off" position. Open the main power disconnect switch for the Condensing Unit and Air Handling Unit and "lock it" in the "Off" position before removing any access panels.

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.

[ ] Inspect the return air filters. Clean or replace them if necessary.

[ ] Check the evaporator drain pan and condensate piping to ensure that there are no blockages.

[ ] Inspect the evaporator coils for dirt. If the coils appear dirty, clean them according to the instructions described in the “Coil Cleaning” section.

[ ] Inspect the economizer damper hinges and pins (if applicable) to ensure that all moving parts are securely mounted. Clean the blades 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.

[ ] Lubricate the supply fan bearings. Refer to the equipment manufacturer for their recommended greases.

NOTICE

Over lubrication can be just as harmful as not enough grease.

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 to the bearings and Fan wheels. Make sure that all bearing supports are tight.

[ ] Check the supply fan belt(s). If the belts are frayed or worn, replace them.
