Routine Maintenance By Owner
You can do some of the periodic maintenance functions for your unit yourself; this includes clean-
ing air filters, cleaning unit cabinet, cleaning the condenser coil, and conducting a general unit in-
spection on a regular basis.
Unfiltered air circulates through the unit's condenser coil and can cause the coil's surface to be-
come clogged with dust, dirt, etc.. To clean the coil, vertically (i.e., along the fins) stroke the coil
surface with a soft bristled brush.
Keep all vegetation away from the condenser coil area.
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 fil-
ters 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).
