Usage
Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not
expose occupants, pets, or plants to direct airflow for extended periods of time.
Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other
heating devices.
Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices,
food, pets, plants, and art objects). Usage in such a manner could harm such property.

Cleaning and maintenance
Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp
metal edges.
Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading
to possible electric shock.
When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a
very high speed during operation. There is a possibility of injury if the unit’s power is accidentally
triggered on while cleaning inner parts of the unit.

When the air conditioner has been performed its
cooling or heating operation and is turned off or
set to the fan position, wait at least 3 minutes
before resetting to the cooling operation again.
A slight heat odor may come from the unit when
first switching to HEAT after the cooling season is
over. This odor, caused by fine dust particles on
the heater, will disappear quickly. This is
harmless.
NOTICE
CAUTION

The ventilation lever is located at the lower left side of the unit.
The ventilation lever must be in the CLOSE position in order to
maintain the best cooling conditions.
When fresh air is necessary in the room, set the ventilation lever to
the OPEN position.
The damper is opened and outdoor air is drawn into the room.
This will reduce the cooling or heating efficiency.

to maintain optimal performance of the air conditioner.
How to remove the air filter
Pull the tab slightly to release the filter.
Clean the filter with warm, soapy water. The water
should be below 40°C (104°F).
Rinse off and gently shake off excess water from the
filter. Let it dry before replaceing it.
Do not operate the unit without the filters in place.
Replace the filter immediately when it is torn or
damaged.
When the unit operate without the filters in place or with
damaged filters, it reduce the cooling or heating, airflow
and efficiency of the unit as the indoor heat exchanger
allow dust and dirt.

Product Features
Before Installing the unit
This appliance should be installed in accordance with national wiring regulations. This guide acts as a guide to
help to explain product features.
CAUTION
Use the correct wall sleeve and outdoor grille
This unit is designed to be installed in the insulated wall
sleeve. When you replace the unit into the existing sleeve,
all wall sleeve used to mount the new unit must be in good
structural condition and have the outdoor grille that
securely attaches to the sleeves or the flange of the sleeve
to secure the new air conditioner.
With the LG sleeve, you can maintain the best
performance of the new air conditioner.
If you keep the existing sleeve, you run the risk of poor
performance or product failure. This is not covered
under the LG warranty.
Remove the vertical deflectors in the existing grille to
reduce condenser air recirculation that can cause the unit
to poor cooling or heating and component failure.

How to Install the Unit
•There are sharp edges that can cause serious cuts.
•When lifting the air conditioner, it is HEAVY.
Use 2 people to lift.
For existing sleeve, you should measure the wall sleeve
dimensions.
You can install the new air conditioner according to these
installation instructions to achieve the best performence. All
wall sleeves used to mount the new air conditioner must be
in good structural condition and have the rear grille that
securely attaches to the sleeve or the flange of the sleeve to
secure the new air conditioner.
•To avoid vibration and noise, make sure the unit is
installed securely and firmly.
When installing the sleeve, make certain there is nothing
within 20" of the back that would interfere with heat radiation
and exhaust air flow.
To maintain the best performance of
the LG PTAC, an insulation strip
must be attached. The insulation
strip is provided with the box.
Refer to the diagram below.
1) Take out the insulation strip from the upper packing.
2) Attach the insulation strip onto the rear upper side of the
wall sleeve.
3) If anyone would like to improve unit energy efficiency, it is
recommended the change of outside grille for an unit
protection and an addition of a plastic rear grille. (This is
optional.)

Electrical Safety
IMPORTANT (PLEASE READ
CAREFULLY)
FOR THE USER'S PERSONAL SAFETY, THIS
APPLIANCE MUST BE PROPERLY GROUNDED
The power cord of this appliance is equipped with
a three-prong (grounding) plug. Use this with a
standard three-slot (grounding) wall power outlet to
minimize the hazard of electric shock. The
customer should have the wall receptacle and
circuit checked by a qualified electrician to make
sure the receptacle is properly grounded.
DO NOT CUT OR REMOVE THE THIRD
(GROUND) PRONG FROM THE POWER PLUG.
A. SITUATIONS WHEN THE APPLIANCE WILL
BE DISCONNECTED OCCASIONALLY:
Because of potential safety hazards, we strongly
discourage the use of an adapter plug. However, if
you wish to use an adapter, a TEMPORARY
CONNECTION may be made. Use UL-listed
adapter, available from most local hardware
stores.
The large slot in the adapter must be aligned with
the large slot in the receptacle to assure a proper
polarity connection.
: Attaching the adapter ground terminal to the
wall receptacle cover screw does not ground
the appliance unless the cover screw is metal,
and not insulated, and the wall receptacle is
grounded through the house wiring. The
customer should have the circuit checked by a
qualified electrician to make sure the receptacle
is properly grounded.
Disconnect the power cord from the adapter, using
one hand on each. Otherwise, the adapter ground
terminal might break. DO NOT USE the appliance
with a broken adapter plug.
B. SITUATIONS WHEN THE APPLIANCE WILL
BE DISCONNECTED OFTEN.
Do not use an adapter plug in these situations.
Unplugging the power cord frequently can lead to
an eventual breakage of the ground terminal. The
wall power outlet should be replaced by a
three-slot (grounding) outlet instead.
USE OF EXTENSION CORDS
Because of potential safety hazards, we strongly
discourage the use of an extension cord. However,
if you wish to use an extension cord, use a CSA
certified/UL-listed 3-wire (grounding) extension
cord, rated at 15A, 125V.

Common Problems and Solutions
Common
Issues
Before calling for service, please review the following list of common problems and solutions.
The air conditioner is operating normally when:
•You hear a pinging noise. This is caused by water being picked up by the condenser on rainy days or in highly
humid conditions. This feature is designed to help remove moisture in the air and improve cooling efficiency.
•You hear the thermostat click. This is caused by the compressor cycle starting and stopping.
•You see water dripping from the rear of the unit. Water may be collected in the base pan in highly humid
conditions or on rainy days. This water overflows and drips from the rear of the unit.
•You hear the fan running while the compressor is silent. This is a normal operational feature.
The air conditioner may be operating abnormally when:
Problem Possible Causes What To Do
■The air conditioner is unplugged or
not plugged in completely
■The fuse is blown/circuit breaker is
triggered
■Power failure.
■Air flow is restricted
■The TEMPERATURE CONTROL
may not be set cool enough
■The air filter is dirty.
■The air conditioner was just
turned on.
■Cold air is escaping.
