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.

INSTALLATION
NOTICE
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.
ITEMS IN INSTALLATION HARDWARE
All wall sleeves used to mount the new Air
Conditioner must be in sound structural condition
and have a rear grille that securely attaches to
sleeve, or rear flange that serves as a stop for the
Air Conditioner.
2 Remove old air conditioner from existing wall
sleeve.
3
Clean the interior of an existing sleeve.
(Do not disturb seals.)
4
Wall sleeve must be securely fastened in wall
before installing the air conditioner. Use the
nails or screws through sleeve into wall, if
needed. Repaint sleeve if needed.
5
Prepare the wall sleeve for installation of the

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.
1. Open the inlet grille downward by pulling out the top of the
inlet grille.
2. Remove the air filter from the front grille assembly by
pulling the air filter up slightly.
3. Wash the filter using lukewarm water below 40°C (104°F).
4. 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.
1. Pull down front grille from the cabinet top.
2. Push front grille’s tips toward the cabinet in

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
Problem
Air conditioner
does not start
Possible Causes
■ The air conditioner is
unplugged.
• Make sure the air conditioner plug is pushed
completely into the outlet.
■ The fuse is blown/circuit
breaker is tripped.
• Check the house fuse/circuit breaker box and replace
the fuse or reset the breaker.
■ Power failure.
• If power failure occurs, turn the mode control to OFF.
When power is restored, wait 3 minutes to restart the
air conditioner to prevent tripping of the compressor
overload.
■ The current interrupter
device is tripped.
• Press the RESET button located on the power cord
plug. If the RESET button will not stay engaged,
discontinue use of the air conditioner and contact a
qualified service technician.
• Make sure there are no curtains, blinds, or furniture
blocking the front of the air conditioner.
■ Airflow is restricted.

What To Do
■ TEMP Control set too
higher number.
• Set the TEMP control to a lower number.
■ The air filter is dirty.
• Clean the filter at least every 2 weeks.
See the operating instructions section.
■ The room may have been
hot.
• When the air conditioner is first turned on,
you need to allow time for the room to cool down.
■ Cold air is escaping.
• Check for open furnace floor registers
and cold air returns.
• Set the air conditioner's vent to the closed position.
■ Cooling coils have iced up.
• See Air Conditioner Freezing Up below.
■ Ice blocks the air flow and
stops the air conditioner
from cooling the room.
• Set the mode control at High Fan or High Cool with
the high temperature.
