AM30 Air Module and Filters
Having a clean filter is the most important step in keeping your new
heating and air conditioning system working to its full potential.
Dirt, dust and pet hair clog the filter as air cycles through the system.
Dirty filters make the equipment work harder which causes the unit
to use more energy than normal. A system with dirty filters will not
provide you with the comfort you expect. Cleaning or
replacing the filter is much less expensive than higher
energy bills or damaged equipment.
Make sure that all the power is OFF to the unit
before attempting to change filter. Have the dealer
show you where your unit's filter is located. The
filter may be found either inside or outside the
AM30 air module or in the wall at the return air
grille. If the filter is in the air module, it may be
inside the unit behind an access panel or located on
the side of the unit in an external filter rack. If
replacement is necessary, always replace it with the
same type of filter. If you don't know what filter you
need, call your Lennox dealer with the model
number of the unit. The dealer will be able to tell you
what type and size filter you need.
The filter shipped with the AM30 unit is reusable and can be
cleaned with a mild soap and water. The filter should be completely dried before being returned to the
unit . When replacing, look for the airflow direction arrow marked on the filter. Disposable filters (used
at the return air grille) cannot be cleaned but should be replaced every month. During times of heavy
usage, it is beneficial to vacuum the filter in between changes or cleanings.
Your system may include an electronic air cleaner which rids your home of even the smallest particles of
dirt, dust and pollen. Ask your Lennox dealer to instruct you on its maintenance.
