Cabinet Cleaning

Be sure to unplug the air conditioner to prevent shock or fire hazard. The cabinet and front
may be dusted with an oil-free cloth or washed with a cloth dampened in a solution of warm
water and mild dishwashing detergent. Rinse thoroughly and wipe dry.

Never use harsh cleaners, wax, or polish on the cabinet front.

Be sure to wring excess water from the cloth before wiping around the controls. Excess water
in or around the controls may cause damage to the air conditioner.
