PERFORMING

ROUTINE

MAINTENANCE

With proper maintenance and care,

your furnace will operate economi-

cally and dependably. Instructions

for basic maintenance follow. How-

ever, before beginning maintenance,

follow these safety precautions:

FILTERING OUT

TROUBLE

Dirty air ﬁlters 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 even-

tually lock out. It is recommended

that furnace air ﬁlters be checked

every 3 or 4 weeks and cleaned or

replaced as necessary.

The air ﬁlter is installed in an ex-

ternal ﬁlter rack which is provided

a standard equipment with furnace.

To inspect, clean, and/or replace air

ﬁlter, follow these steps:

1. Turn off electrical supply to fur-

nace. (See Fig. 11.)

2. Remove ﬁlter from external ﬁl-

ter rack.

3. Inspect ﬁlter. If torn, replace it.

NOTE:

If ﬁlter has been replaced

with an electronic air cleaner

(EAC), refer to the EAC Owner’s

Manual for maintenance informa-

tion.

5. If ﬁlter is dirty, it must be re-

placed. If your furnace air ﬁlter

needs to be replaced, be sure to

use the same size and type of ﬁl-

ter that was originally supplied.

Use furnace ﬁlter table for ﬁlter

size and ﬁlter rack ﬂange dimen-

sions for return air duct.

FURNACE AIR FILTER TABLE

If you have replaced a disposable

ﬁlter with a permanent washable

ﬁlter, it may be cleaned if it is dirty.

Wash ﬁlter in a sink, bathtub, or

outside with a garden hose. Always

use cold tap water. A mild liquid

detergent may be used if necessary.

Spray water through ﬁlter in the

opposite direction of airﬂow.

Allow ﬁlter to dry.

6. Re-install clean air ﬁlter.

7. Turn on electrical supply to

furnace.

A CHECK-UP

CHECKLIST

Your furnace represents an impor-

tant investment in your family’s

comfort and your home’s value. To

keep it performing properly and as

a preventative to future problems,

have a trained service specialist

give your furnace a professional

check-up annually. The following

checklist can be used as a guideline

to proper service:

WARNING

Turn off all electrical power to

furnace before performing

any maintenance or service

on unit. Failure to take this

precaution may result in per-

sonal injury due to electrical

shock.

CAUTION

Although special care has

been taken to minimize sharp

edges, be extremely careful

when handling parts or

reaching into the furnace.

CAUTION

Never operate your furnace

without the air filters in place.

Doing so may damage the

furnace blower motor. An ac-

cumulation of dust and lint

on internal parts of your fur-

nace can cause a loss of effi-

ciency.
