Cleaning

WARNING

• Before cleaning or performing maintenance, disconnect the power supply and wait until the fan stops.

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.
2. Wash the filter using lukewarm water below 40 ºC (104 ºF).
3. Gently shake the excess water from the filter and replace it.
4. Dry the filter in the shade.
5. Insert the filter into the Front grille.

Cleaning the Air Conditioner

• Wipe the front grille and inlet grille with a cloth dampened with 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 the product) should be checked periodically and cleaned if clogged with soot or dirt from outside air.
• For repair and maintenance, contact an LG Electronics Customer Service Hotline. Have your model number and serial number available.
