Your air conditioner is designed for year-round
operation with only minimal cleaning and
maintenance.
For maximum efficiency, it is recommended
that you have the cooling coils inspected and
cleaned annually. Your local LG Authorized
Service Center can provide this inspection
and cleaning service for a nominal fee.
WARNING
• Unplug the air conditioner before cleaning or performing any maintenance or servicing.
• Be careful when cleaning coils or removing or reinstalling the filter-the cooling fins
are sharp!
Failure to follow the above precautions could result in electrical shock or personal injury.
5-1 CLEANING THE CASE
Wipe the case with a slightly damp cloth, then wipe dry
with a dry cloth or towel.
5-2 CLEANING THE AIR FILTER
The air filter should be cleaned every two weeks; depending on indoor air quality, more
frequent cleaning may be needed. A dirty air filter will decrease airflow and reduce efficiency.
Do not operate the air conditioner without
the air filter in place.
Grasp the grip which is in the center and on the top of
the filter and pull out the filter directly.
1
Use a vacuum cleaner to clean the filter. If the filter is
heavily soiled, it can be washed in warm water using a
mild detergent.
Do not use harsh cleaners or very hot water.
Do not wash in a dishwasher.
Allow the filter to dry completely before reinstalling.

• To prevent damage to the finish, do not use gasoline,
benzene, thinner, etc., or any abrasive cleansers to
clean the air conditioner; they may damage the finish.
• Never pour water onto or into the air conditioner.
It could damage internal components and create a
shock and fire hazard.
Reinsert the filter, making sure that the bottom of the
filter is between the tabs and the coil guard. Reinstall
the filter cover, making sure it clips into place.

3 pints of water.
Remove the drain cap and the rubber plug from the drain outlet.
Once the water collection tank is drained, reinstall the rubber plug and the drain cap, making sure it is
on securely.
Place the air conditioner in the desired location, reconnect the exhaust hose, and plug in the air
conditioner.
When need running in high humidity, or during the DRY mode remove the drain cap and the

ENERGY
SAVER
Under normal operation, the exhaust fan cycles on
