Performing Routine Maintenance, Filtering Out Trouble

PERFORMING ROUTINE MAINTENANCE

With proper maintenance and care, your furnace will operate

econonfically and dependably. Instructions for basic maintenance

are found on this and the following pages. However, before

beginning maintenance, follow these safety precautions:

ELECTRICALSHOCKHAZARD

Failure to follow this warning could result in personal injury or death.

Turn off electrical power supply to your furnace before

removing the access doors to service or perform maintenance.

CUT HAZARD

Failure to follow this caution may result in personal iniury.

Although special care has been taken to nfininfize sharp

edges, be extremely careful when handling parts or reaching

into the furnace. Wear safety glasses, gloves, and

appropriate protective clothing.

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 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.
