How to Clean your Filter
Permanent type, washable, High-velocity filters may be cleaned with a
vacuum cleaner or taken away from the unit & washed with a garden
hose. Be sure to shake off excess water and allow filter to completely
dry before re-installing the filter.
CONDENSATE DRAIN LINES
Coils maybe included in the air handler or separately mounted. During
the cooling season check the condensate drain lines to be sure that
condensate is flowing from the primary drain but not from the secondary
drain. If condensate ever flows from the secondary drain the unit should
be promptly shut off and the condensate pan and drains cleaned by a
qualified service technician to insure a free flowing primary drain.
COIL CLEANING
If an inspection by a qualified service technician indicates the coil needs
to be cleaned, it can be washed with water.
BLOWER CARE
Even with good filters properly in place, blower wheels and motors will
become dust laden after long months of operation. The entire blower
assembly should be inspected annually. If the motor and wheel are
heavily coated with dust, they can be brushed and cleaned with a vac-
uum cleaner. If the blower cannot be properly cleaned without removing
it from the air handler, then this service must be performed by a quali-
fied service agency.
WARNING
Make sure you DO NOT move the clip on weight on the indoor fan
wheel when cleaning the wheel. This weight is used to balance the
wheel. Moving the weight will cause the fan wheel to vibrate.
