Page 3

FIRE,EXPLOSION, ELECTRICAL SHOCK HAZARD

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

1. TURN OFF ELECTRICAL POWER TO YOUR UNIT BEFORE SERVICING OR PERFORMING MAINTENANCE.

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

The air filter(s) should be checked at least every 3 months and changed or cleanedwhenever it becomesdirty.Dirty filtersproduce excessive stress on the blower motor and can cause the motor to overheat and shut down.

This unit must have an air filter in place before it can be operated. These filters should be locatedin at least one of two places. In many applications, the installer will provide return air filter grilles mounted on the wall or ceiling of the conditioned structure. In the instance of filter grilles, the filters can simply be removed from the grille and replaced.

The other typical application is an accessory filter rack installed inside the unit itself. The following information is given to assist in changing filters used in these internal filter racks.

Table 1 indicates the correct filter size for your unit.

Unit Size Filter Size

704C024 --- 030 20x24x1

704C036 24x30x1

704C042 --- 060 24x36x1

To replace or inspect filters in accessory filter rack:

1. Remove the filter access panel (See Fig. 2) using a 5/16--in. nut driver.

2. Remove the filter(s) by pulling it out of the unit. If the filter(s) is dirty, clean or replace with a new one.

When installing the new filter(s), note the direction of the airflow arrows on the filter frame.

If you have difficulty locating your air filter(s) or 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.
