Routine Maintenance By Owner

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

Above 6.25RT
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).
Below 5RT
This unit is shipped without a filter and is the responsibility of the installer to secure a filter in
the return air ductwork.
Filter must always be used and must be kept clean. When filter become dirt laden,
insufficient air will be delivered by the blower, decreasing your unit efficiency and increasing
operating costs and wear - and - tear on the unit and controls. Filter should checked monthly
especially since the unit may be used for both heating and cooling.
