WARNING! PREVENT INJURY. ALWAYS SHUT OFF POWER DURING CLEANING PROCESS.

• The exterior surfaces must be cleaned with a mild detergent and warm water to protect and maintain their attractive finish. Never use abrasive cleansers or scouring pads.

1. Using a flat object such as a screw driver, compress the honeycomb and remove it from its retainer.

2. Clean and dry the honeycomb.

3. After cleaning, replace in reverse order.

• The interior back panels may be removed for cleaning and to gain access to the evaporator coils. Remove the rear interior back panels as follows:
