If your furnace filter needs replacing, be sure to use the same size and type of filter that was originally supplied.

Use the Furnace Filter Table and match your furnace size with the proper filter size .

!CAUTION

Never operate your furnace without a filter in place. Doing so may damage the furnace blower motor. An accumula- tion of dust and lint on internal parts of your furnace can cause a loss of efficiency.

The air filter for upflow furnaces is nor- mally located in the blower compart- ment (See Fig. 2) or in the factory- supplier filter cabinet attached to the side or bottom of the blower cabinet. Filters for the downflow furnaces are normally located in the return-air ple- num above the blower. If air filter has been installed in another location, con- tact your dealer for instructions. To in- spect, clean, and/or replace the air filter(s), follow these steps:

•UPFLOW FURNACES ONLY—

1.Turn off electrical supply to fur- nace. (See Fig. 21)

2.Remove door/access panel

•AIR FILTER(S) LOCATED IN BLOWER COMPARTMENT

•AIR FILTER LOCATED IN BLOWER COMPARTMENT:

a.Slide filter retainer sideways until it is free of latch. (See Fig. 24)
