ATTEMPTING ANY MAINTENANCE.
FAILURE TO DO SO CAN CAUSE
ELECTRICAL SHOCK RESULTING IN
SEVERE PERSONAL INJURY OR
DEATH.

FILTERS

Filter application and placement are
critical to airflow, which may affect the
heating and cooling system perfor-
mance. Reduced airflow can shorten
the life of the systems major compo-
nents, such as motor, limits, elements,
heat exchanger, evaporator coil or com-
pressor. Consequently, we recommend
that the return air duct system have
only one filter location. The most com-
mon location will be inside the furnace
or a filter base. For systems with a
return air filter grill or multiple filter
grills, can have a filter installed at each
of the return air openings. DO NOT
DOUBLE FILTER THE RETURN AIR
DUCT SYSTEM. DO NOT FILTER THE
SUPPLY AIR DUCT SYSTEM.
If high efficiency filters or electronic air
cleaners are used in the system, it is
important that the airflow is not reduced
to maximize system performance and
life. Always verify that the systems air-
flow is not impaired by the filtering sys-

Keep the air filters clean at all times.
Vacuum dirt from filter, wash with deter-
gent and water, air dry thoroughly and
reinstall.
See Table 19 and Figures 42 through

IMPORTANT: Do not operate the
system without filters. A portion of
the dust entrained in the air may
temporarily lodge in the air duct runs
and at the supply registers. Any cir-
culated dust particles will be heated
and charred by contact with the fur-
nace heat exchanger. This sooty
residue will soil ceilings, walls,
drapes, carpets, and other house-
hold articles. Soot damage may also
result when certain types of candles
are burned, or candlewicks are left
untrimmed.
