Filter
Top Products
Note: Do not attempt to clean
disposable filters. Permanent 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).
Note: Replace permanent filters
annually if washing fails to clean
them, or they show signs of
deterioration. Be sure to use the
same type and size as were
originally installed.
Condenser coil
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, brush the coil surface in the
direction of the fins with a soft
bristled brush.
Keep all vegetation away from the
condenser coil area.
Hot water coil (option)
Stop the unit. Do not disconnect the
main supply to the unit. This will
permit the anti-frost protection to
continue to operate, and avoid
water to freeze-up in the coil.
