MAINTENANCE AND CARE FOR THE EQUIPMENT

OWNER

Before proceeding with those things you might want to maintain

yourself, please carefully consider the following:

1. TURN OFF ELECTRICAL POWER TO YOUR UNIT

BEFORE SERVICING OR PERFORMING MAINTE-

NANCE.

2. When removing access panels or performing maintenance

functions inside your unit, be aware of sharp sheet metal

parts and screws. Although special care is taken to reduce

sharp edges to a minimum, be extremely careful when

handling parts or reaching into the unit.

AIR FILTERS — Air filter(s) should be checked at least every 3

or 4 weeks and changed or cleaned whenever it becomes dirty.

Dirty filters produce excessive stress on the blower motor and can

cause the motor to overheat and shut down. Table 1 indicates the

correct filter size for your unit. Refer to Fig. 2 to access the

filter(s).

To replace or inspect filter(s) (or accessory filter rack when

supplied):

1. Remove the filter access panel using a 5/16-in. nut driver.

2. Remove the filter(s) by pulling the filter(s) out of the unit. If

the filter(s) is dirty, clean or replace with new one.

When installing the new filter(s), note the direction of the airflow

arrows on the filter frame.

If you have difficulty in locating your air filter(s), or if you have

questions concerning proper filter maintenance, contact your

dealer for instructions. When replacing filters, always use the same

size and type of filter that was supplied originally by the installer.
