Before Operation
Preparing for Operation
- Contact an installation specialist for installation.
- Plug in the power plug properly.
- Use a dedicated circuit.
- Do not use an extension cord.
- Do not start/stop operation by plugging/unplugging the power cord.
- If the cord/plug is damaged, replace it with only an authorized replacement part.
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). Such usage could damage the items.
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.
Service
For repair and maintenance, contact your authorized service dealer.

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.
CAUTION:
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, usea CSA
certified/UL-listed 3-wire (grounding) extension cord, rated at 15A, 250V.
Installation
Remove packing materials from the wall sleeve and tape from the air conditioner.
INSTALLATION REQUIREMENTS
If you use an existing wall sleeve, you should measure its dimensions.
Install the new air conditioner according to these installation instructions
to achieve the best performance. All wall sleeves used to mount the new air
conditioner must be in good structural condition and have a rear grille to
securely attach the new air conditioner. (FIG. 1)
With the LGE sleeve(optionally supplied with your unit), you can maintain the
best performance of the new air conditioner. (FIG. 2)
ELECTRICAL SERVICE
Check your available electrical service. The power supply available must be
the same as that shown on the unit nameplate (found on left side of cabinet).
All models are equipped with a 3-prong service plug to provide proper service
and safe positive grounding. Do not change plug in any way. Do not use an
adapter plug. If your present wall outlet does not match your plug, call a
qualified electrician to make the necessary corrections. SAVE CARTON for
storage and this OWNER’S MANUAL for future reference. The carton is the best
way to store unit during winter or when not in use.

INSTALLATION
CAUTION:
We strongly recommend the removal of the old wall sleeve and the
installation of a new LGE Wall Sleeve.
If you decide to keep the existing wall sleeve, you have to redirect the
louvers at the back of the wall sleeve illustration. The use of pliers is
recommended. If you DO NOT redirect, you run the risk of poor performance or
product failure. This is not covered under the terms of the LGE warranty.
- Pick a location which will allow the conditioned air to blow into the area you want. Good installation with special attention to the proper position of the unit will lessen the chance that service will be needed.

to run at its last setting.
Remote control
The remote control and control panel will look like one of the following
pictures.
How to insert Batteries
-
Remove the cover from the back of the remote controller.
-
Insert two batteries.
• Be sure that the (+) and (-) directions are correct.
• Be sure that both batteries are new. -
Re-attach the cover.
- Do not use rechargeable batteries. Such batteries differ from standard dry cells in shape, dimensions, and performance.
- Remove the batteries from the remote controller if the air conditioner is not going to be used for an extended length of time.
Ventilation
The ventilation lever is located in the right of the air discharge.
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 room air is exhausted outside.
Air Direction
The direction of air can be controlled wherever you want by adjusting the
horizontal louver and the vertical louver.
-
HORIZONTAL AIR-DIRECTION CONTROL
The horizontal air direction is adjusted by moving vertical louver.
The lever of vertical louver is located in the right and left side of the air discharge. -
VERTICAL AIR-DIRECTION CONTROL
The vertical air direction is adjusted by moving the horizontal louver.
Maintenance and Service
TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.
Air Filter Cleaning
The air filter should be checked at least twice a month to see if cleaning is
necessary.
Trapped particles in the filter will build up and block the airflow. This
reduces the cooling capacity and also causes an accumulation of frost on the
cooling coils.
If the filter becomes turn or damaged you should replace immediately.
Replacement filters are available from your salesperson, dealer, and the
authorized customer service centers.
- Open the inlet grille downward by pulling out the top of the inlet grille.
- Remove the air filter from the front grille assembly by pulling the air filter up slightly.
- Wash the filter using lukewarm water below 40°C (104°F).
- Gently shake the excess water from the filter completely. Replace the filter.
How to Attach Front Grille to Cabinet
The front grille can be removed for cleaning or to check the model and serial
numbers.
For your safety, you should attach the front grille as the following
procedures.
- Pull down front grille from the cabinet top.
- Push front grille’s tips toward the cabinet in order to insert front grille’s tabs into the cabinet.
- Open the inlet grille.
- Tighten the screw through the front grille into the plate of control box.
- Close inlet grille.
Common Problems and Solutions
Troubleshooting Tips Save time and money!
Review the chart below first and you may not need to call for service.
Normal Operation
- You may hear a pinging noise caused by water being picked up and thrown against the condenser on rainy days or when the humidity is high. This design feature helps remove moisture and improve efficiency.
- You may hear the thermostat click when the compressor cycles on and off.
- Water will collect in the base pan during high humidity or on rainy days. The water may overflow and drip from the outdoor side of the unit.
- The fan may run even when the compressor does not.
Troubleshooting
