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.
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.
