Failure to follow this caution may result in product damage.
Never operate your furnace without a filter in place. Doing
so may damage the furnace blower motor.
accumulation of dust and lint on internal parts of your
furnace can cause a loss of efficiency.
A dirty filter will cause excessive stress on the furnace, heat
exchanger, and blower motor and can cause it to overheat and
automatically shut down. The furnace filter should be checked
every 4 weeks and cleaned or replaced if necessary.
If installed with factory specified disposable media filter, check or
replace filter before each heating and cooling season. Replace
disposable media filter at least twice a year.
If your furnace filter needs replacing, be sure to use the same size
and type of filter that was originally specified. The air filter for the
furnace may be located in a filter cabinet attached to the side or
bottom of the furnace. If air filter has been installed in another
location, contact your dealer for instructions. To inspect, clean
and/or replace the air filter(s), follow these steps:
1. Turn off the electrical supply to the furnace.
