AIR HANDLER MAINTENANCE
At the beginning of each heating season the unit should be
serviced by a qualified installer or servicing agency.
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 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.
•
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 secondary drain line, a
problem exists which should be investigated and
corrected. Contact a qualified person.
