HOW TO USE
BEFORE USING YOUR AIR CONDITIONER
PREPARING FOR OPERATION
Refer to the Installation Instructions included in
this manual before using the air conditioner.
Once the air conditioner has been properly
assembled and installed:
Plug the power cord into its own dedicated
1
properly grounded outlet. You will hear a
tone to confirm that the conditioner is
plugged in. Do not plug other appliances
into the same outlet; it could overload the
outlet and create a fire hazard.
Make sure the air conditioner and cord is
2
positioned where it does not create a
tripping hazard and will receive adequate
ventilation. Do not place it directly next to
furniture or objects that could block the
vent openings.
Make sure that any items that could be
3
blown over or damaged by the airflow from
the fan are out of the airflow path.
UNPACKING THE AIR CONDITIONER
Remove and store packing materials for reuse.
Remove any shipping tape before using the
air conditioner. If the tape leaves behind any
adhesive, rub a small amount of liquid dish
soap onto it and wipe with a damp cloth. Do
NOT use sharp instruments, alcohol, thinners,
or abrasive cleaners to remove adhesive.
They could damage the finish.
IMPORTANT:
• Do not remain in the direct airflow from the air
conditioner for extended periods of time.
• To prevent damage or injury to pets and
plants, make sure they are not exposed to
direct airflow from the air conditioner.
• When used at the same time as stoves,
fireplaces, and other combustion devices,
make sure there is a sufficient flow of fresh air
into the room. Do not use in tightly enclosed
spaces with these types of devices.
• This air conditioner is intended for household
use as a consumer comfort appliance. Do not
use it as a precision climate control system,
or for purposes such as cooling precision
equipment, food, pets, plants, artwork, etc.
Such items could be damaged.
• Do not bend the hose downward when
window installation kit is not applied. It may
cause failure of air conditioner or performance
deterioration.

CARE AND CLEANING
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.
CLEANING THE CASE
Wipe the case with a
slightly damp cloth, then
wipe dry with a dry cloth
or towel.
• 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 unit; it
could damage internal components and
create a shock and fire hazard.

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.
Filter

2
the filter is heavily soiled, it can be washed
in warm water using a mild detergent.

wat er. Do not wash in a dish asher
3
Allow the filter to dry completely before
reinstalling.
Reinsert the filter , making sure that the

thecoil guard. Reinstall the filter cover,
making sure it clips into place.
