Filtering Out Trouble

UNIT PERFORMANCE HAZARD

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. An

accumulation of dust and lint on internal parts of your furnace can cause a loss of efficiency.

A dirty air filter will cause a loss of airflow in your duct system. When excessive loss of airflow occurs, the furnace may cycle on

its safety controls. If this condition is left unattended, the furnace

will eventually lock out. It is recommended that the furnace air filter be checked eve_ 3 or 4 weeks and cleaned if necessa_.

If installed with factory-specified disposable media filter, check

or replace filter before each heating and cooling season. Replace

disposable media filter at least once a year.

The air filter is normally located in the blower compartment or

in the factory-supplied filter cabinet attached to the side or

bottom of the furnace casing. 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 electrical supply to furnace. (See Fig. 17.)

2.Remove door/access panel.
