22 MAINTENANCE MAINTENANCE WARNING Before cleaning or performing maintenance, disconnect the power supply and wait until the fan stops. 2 Wash the filter using lukewarm water below 40 °C (104 °F). Air Filter Check the air filter at least twice a month to see if cleaning is necessary. Trapped particles in the filter can build up and block the airflow, reducing cooling capacity and causing an accumulation of frost on the evaporator. Cleaning the Air Filter 1 Remove the air filter from the front grille by pulling the filter forward and then up slightly. 3 Gently shake the excess water from the filter and replace. Cleaning the Air Conditioner ● Wipe the front grille and inlet grille with a cloth dampened in a mild detergent solution. ● Wash the cabinet with mild soap or detergent and lukewarm water, then polish using liquid appliance wax. NOTE To ensure continued peak efficiency, the condenser coils (outside of unit) should be checked periodically and cleaned if clogged with soot or dirt from outside air. ● For repair and maintenance, contact an Authorized Service Center. See the warranty page for details or call 1-800-243-0000. Have your model number and serial number available. They can be found on the side of the cabinet. Record them on page 28 for future reference.
