CARE AND MAINTENANCE
CAUTION
!
• Before performing any maintenance, turn off the main power to the system.
You can do some of the periodic maintenance for your unit yourself; this includes cleaning air fil-
ters, cleaning unit cabinet, clearing 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 discon-
nect power before attempting any servicing can result in severe injury or death.
This product has anti-bacteria washable filters. It is very important to keep air filters clean in the
central duct system. 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.)
Washable type filters can be cleaned by washing with a mild detergent and water. Ensure that
the filters are thoroughly dried before reinstalled them in the unit (or duct system).
Unfiltered air circulates through the unit's condenser coil and can cause the coil's surface to
become 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.
