■Meanings of symbols used in this manual are as shown below.
This symbol indicates the possibility of death or serious injury.
This symbol indicates the possibility of injury or damage to properties only.
Carefully read the labels affixed to the main unit.
Be sure not to do.
Be sure to follow the instruction.
This symbol indicates a part which must be grounded.
This symbol indicates that caution should be taken with rotating parts.
(This symbol is displayed on the main unit label.) <Color: Tellow>
This symbol indicates that the main switch must be turned off before service.
(This symbol is displayed on the main unit label.) <Color: Blue>
This symbol alerts you to the risk of electric shock.
(This symbol is displayed on the main unit label.) <Color: Yellow>
This symbol alerts you to the risk of hot surface.
(This symbol is displayed on the main unit label.) <Color: Yellow>

NOTICE
This symbol indicates special notes.
ELV
Pay attention to electric shock.
And at servicing, please shut down the power supply for both of Indoor and Outdoor
Unit.

6Indoor Unit
Safety Precautions
Use the specified cables for wiring. Make the
connections securely so that the outside force
of the cable is not applied to the terminals.
- Inadequate connection and fastening may gen-
erate heat and cause a fire.
Always use accessories specified by LG
Electronics.
- Ask an authorized technician to install the
accessories. Improper installation by the user
may result in water leakage, electric shock, or
fire.
Cautions before installation
Never repair the unit. If the air conditioner
must be repaired, consult the dealer.
- If the unit is repaired improperly, water leakage,
electric shock, or fire may result.
Do not touch the heat exchanger fins.
- Improper handling may result in injury.
If refrigerant gas leaks during service work,
ventilate the room.
- If the refrigerant gas comes into contact with a
flame, poisonous gases will be released.
Have all electric work done by a licensed
electrician according to "Electric Facility
Engineering Standard" and "Interior Wire
Regulations" and the instructions given in
this manual and always use a special circuit.
- If the power source capacity is inadequate or
electric work is performed improperly, electric
shock and fire may result.
Securely install the cover of control box and
the panel.
- If the cover and panel are not installed properly,
dust or water may enter the outdoor unit and fire
or electric shock may result.
When installing and moving the air condition-
er to another site, do not charge it with a
refrigerant different from the refrigerant
(R407C) specified on the unit.
- If a different refrigerant or air is mixed with the
original refrigerant, the refrigerant cycle may
malfunction and the unit may be damaged.
If the air conditioner is installed in a small
room, measures must be taken to prevent the
refrigerant concentration from exceeding the
safety limit when the refrigerant leaks.
- Consult the dealer regarding the appropriate
measures to prevent the safety limit from being
exceeded. Should the refrigerant leak and cause
the safety limit to be exceeded, hazards due to
lack of oxygen in the room could result.
When moving and reinstalling the air condi-
tioner, consult the dealer or an authorized
technician.
- If the air conditioner is installed improperly, water
leakage, electric shock, or fire may result.

Safety Precautions
Service Manual 7
After completing service work, make sure
that refrigerant gas is not leaking.
- If the refrigerant gas leaks and is exposed to a
fan heater, stove, oven, or other heat source, it
may generate noxious gases.
Do not reconstruct or change the settings of
the protection devices.
- If the pressure switch, thermal switch, or other
protection device is shorted and operated
forcibly, or parts other than those specified by
LG Electronics are used, fire or explosion may
result.
Do not install the unit where combustible gas
may leak.
- If the gas leaks and accumulates around the
unit, an explosion may result.
Do not use the air conditioner where food,
pets, plants, precision instruments, or art-
work are kept.
- The quality of the food, etc. may deteriorate.
Do not use the air conditioner in special envi-
ronments.
- Oil, steam, sulfuric smoke, etc. can significantly
reduce the performance of the air conditioner or
damage its parts.
Do not install the unit on a structure that may
cause leakage.
- When the room humidity exceeds 80% or when
the drain pipe is clogged, condensation may drip
from the indoor unit. Perform collective drainage
work together with the outdoor unit, as required.
Take measures to prevent children from
touching the unit.
- Injuries such as cuts could occur if a child
touches the surface of the fins on the heat
exchanger.
Cautions for electrical work and movement
Ground the unit.
- Do not connect the ground wire to gas or water
pipes, lightning rods, or telephone ground lines.
Improper grounding may result in electric shock.
Install the power cable so that tension is not
applied to the cable.
- Tension may cause the cable to break and gen-
erate heat and cause a fire.
Use power cables of sufficient current carry-
ing capacity and rating.
- Cables that are too small may leak, generate
heat, and cause a fire.
Use only a circuit breaker and fuse of the
specified capacity.
- A fuse or circuit breaker of a larger capacity or a
steel or copper wire may result in a general unit
failure or fire.

8Indoor Unit
Safety Precautions
Do not wash the air conditioner units.
- Washing them may cause an electric shock.
Be careful that the installation base is not
damaged by long use.
- If the damage is left uncorrected, the unit may
fall and cause personal injury or property
damage.
Safely dispose of the packing materials.
- Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.
- Tear apart and throw away plastic packaging bags so that children will not play with them. If children
play with a plastic bag which was not torn apart, they face the risk of suffocation.
Cautions before the test run
Turn on the power at least 12 hours before starting operation.
- Starting operation immediately after turning on the main power switch can result in severe damage to
internal parts. Keep the power switch turned on during the operational season.
Do not touch the switches with wet fingers.
- Touching a switch with wet fingers can cause an electric shock.
Do not touch the refrigerant pipes during and immediately after operation.
- During and immediately after operation, the refrigerant pipes may be hot or cold, depending on the
condition of the refrigerant flowing through the refrigerant piping, compressor, and other refrigerant
cycle parts. Your hands may suffer burns or frost-bite if you touch the refrigerant pipes.
Do not operate the air conditioner with the panels and guards removed.
- Rotating, hot, or high-voltage parts can cause injuries.
Do not turn off the power immediately after stopping operation.
- Always wait at least five minutes before turning off the power. Otherwise, water leakage and trouble
may occur.

Operation Details
■Time Delay Safety Control
•5sec Vertical louvers are delayed for 5 secs to be opened to prevent the frictional sound between louver and air
flow.
•30sec The 4-way valve is ceased for 30sec. to prevent abnormal noise when the Heating operation is OFF or
switched to the other operation mode while compress is off.
While compressor is running, it takes 3~5 seconds to switch.
■Auto Swing Control
•This function is to swing the louver up and down automatically.
■Air-Filter Checking Control
•'Filter' sign will appear on the remote controller display and main body display when an air-filter is polluted. Then
clean the air-filter referring to Owners Manual.
■Soft-Dry Operation
•The indoor fan speed is automatically set to the low, and fan speed control is not available because of already being
set to the best speed for Dry Operation by microcontroller control.
■Cooling Mode Operation
