Routine Maintenance By Owner
You can do some of the periodic maintenance functions for your unit yourself; this includes
cleaning air filters, cleaning unit cabinet, cleaning the condenser coil, and conducting a general
unit inspection on a regular basis.
WARNING: Before removing access panels to service unit, disconnect
power supply. Failure to disconnect power before attempting any
servicing can result in severe injury or death.
Air Filters
It is very important to keep the central duct system air filters clean. Be sure to inspect them at
least once each month when the system is in constant operation. (In new buildings, check the
filters every week for the first 4 weeks.)
These units have anti-fungus filter.
Permanent type filters can be cleaned by washing with a mild detergent and water. Ensure that
the filters are thoroughly dry before reinstalling them in the unit (or duct system).
