PERFORMING ROUTINE MAINTENANCE

With the proper maintenance and care, your furnace will operate economically and dependably. Basic maintenance, which can easily be accomplished by someone who follows the directions, is found on this and the following pages. However, before beginning mainte- nance, follow these safety precautions:

!WARNING

Turn off electrical power sup- ply to your furnace before re- moving the access doors to service or perform mainte- nance. A failure to follow this warning could result in per- sonal injury or death.

!CAUTION

Although special care has been taken to minimize sharp edges, be extremely careful when handling parts or reach- ing into the furnace.

FILTERING OUT

TROUBLE

A dirty filter will cause excessive stress on the furnace blower motor and can cause it to overheat and automatically shut down. The furnace filter should be checked every 3 or 4 weeks and cleaned 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 once a year.

If installed with factory specified dis- posable media filter, check or replace filter before each heating and cooling

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. 03.) 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:
