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.
