AIR HANDLER MAINTENANCE
IMPORTANT: Do not operate system without a filter. A filter is
required to protect the coil, blower, and internal parts from
excessive dirt and dust. See “Installation Configurations” for the
location of the filter in the unit cabinet and the service panel
giving access to unit filter. The filter is placed in the supply air
return duct by the installer.
■ Inspect air filters at least once a month and replace or clean
as required. Dirty filters are the most common cause of
inadequate heating or cooling performance.
■ Replace disposable filters. Cleanable filters can be cleaned
by soaking in mild detergent and rinsing with cold water.
■ Install new/clean filters with the arrows on the side pointing in
the direction of airflow.
■ Do not replace a cleanable (high velocity) filter with a
disposable (low velocity) filter unless return air system is
properly sized for it.
■ If water should start coming from the secondary drain line, a
problem exists which should be investigated and corrected.
Contact a qualified person.
