SAFETY INSTRUCTIONS
Important Safety Instructions
WARNING
Installation
Contact an Authorized Service Center to have
the air conditioner installed.
• Incomplete installation performed by yourself
may result in a water leakage, electric shock,
and fire.
Check the foundation for damaged on a
continuous basis, especially if it has been in
use for a long time.
• It may cause injury or damage to the unit or
other property.
Contact an Authorized Service Center for
repairs, maintenance and to reinstall the
airconditioner.
• Incomplete installation performed by yourself
may result in a water leakage, electric shock,
and fire.
Be sure to only use accessories made by LG
which are specifically designed for use with
the equipment and have them installed by a
professional.
• Improper installation or attachment of
equipment or accessories could result in
electric shock, a short circuit, leaks, fire or
other damage to the equipment.
In the case of refrigerant leakage, consult an
Authorized Service Center. When installing the
air conditioner in a small room, it is necessary
to take proper measures so that even when
it leaks, the amount of any leaked refrigerant
does not exceed the limiting concentration
even when it leaks. If the refrigerant leakage
exceeds the limiting concentration level, an
oxygen deficiency-related accident may occur.
• There isa risk of asphyxiation which could
lead to serious injury or death
Do not install the unit in an area where there
are flammable materials.
• Thereis a risk of explosion that could result
in serious injury or death.
.
Use a vacuum pump or insert (nitrogen) gas
when performing a leakage test or air purge.
Do not allow air etc. to enter the refrigerant
circuit (piping). Never use refrigerants that are
not specified on the specification. label and in
the manuals.
• There is a risk of death, injury, fire or
explosion.
Power
Do not attempt to do electrical work or
grounding work unless you are licensed to do
so. Consult with an Authorized Service Center
for electrical work and grounding work.
• There is a risk.
Do not modify or extend the power cable.
• There is risk of fire or electric shock.

• There is risk of fire or electric shock.
Be sure to install an earth leakage breaker
• There is risk of fire or electric shock.
Always install a dedicated circuit and breaker.
• Improper wiring or installation may cause fire
or electric shock.
Do not turn on the breaker or power if the front
panel, cabinet, top cover, or control box cover
are removed or opened.
• Doing so could cause fire, electric shock,
explosion or death.
Do not use a defective or underrated circuit
breaker. Use this appliance on a dedicated
circuit.

minutes before turning off the power.
• Otherwise, water leakage may occur.
Indoor/outdoor wiring connections must be
secured tightly and the cable should be routed
properly so that there is no force pulling the
cable from the connection terminals.
• Improper or loose connections can cause
heat generation or fire.
Do not touch (operate) the product with wet
hands.
• There is a risk of electrical shock.
Operation
Be sure to use only those parts which are
listed in the SVC parts list. Never attempt to
modify the equipment.
• The use of inappropriate parts can cause an
electrical shock or fire.
Do not install the air conditioner at any place
where flammable gas may leak out. If the gas
leaks out and stays around the air conditioner,
a fire may break out.

injury.
Never use flammable spray such as hair spray,
lacquer or paint near the unit.
• Flammable spray may cause a fire.
If equipment utilizing a burner is used in the
same room as the air conditioner,
there is the danger of oxygen deficiency, which
could lead to asphyxiation. Be sure to ventilate
the room sufficiently to avoid this hazard.
• There is a risk of serious injury or death.
Do not put fingers or other objects into the air
inlet or air outlet. Never remove the fan guard
of the unit.
• The fan rotates at a high speed and will
cause injury.
Never sprinkle or spill water or liquids on unit.
• Doing so could cause fire, failure of the
product, or electric shock.
Never let the indoor unit or the remote
controller get wet.
• Water can cause an electric shock or a fire.
Do not let the air conditioner run while a door
or window is open on a day with high humidity.
This could result in excessive moisture and
water damage.

water damage to walls or furniture.
If there are any abnormalities in the operation
of the air conditioner such as strange sounds,
smoke or fire. turn off the power and contact
an Authorized Service Center immediately.
• There is a risk of severe injury or death.
Take care to ensure that nobody can step on
or fall onto the outdoor unit.
• This could result in personal injury and
product damage.
Stop operation and close all window in storm
or hurricane. If possible, remove the product
from the window before the hurricane arrives.
• There is a risk of property damage, product
failure, or electric shock.
If the product becomes soaked (flooded or
submerged), contact Authorized Service
Center.
• There is a risk of fire or electric shock.
Do not use the product in a tightly closed
space for a long time.
• Doing so could result in a state of oxygen
deficiency.
Maintenance
The heat exchanger fins are sharp edges
enough to cut. To avoid injury, wear gloves or
cover the fins while working around them.
Tear apart and throw away plastic packaging
bags so that children will not play with them.
• Children playing with plastic bags are at risk
of death by suffocation.
Safely dispose of the packing materials. Packing materials, such as nails and other metal or
wooden parts.
• These materials could cause puncture
wounds or other injuries.

SAFETY INSTRUCTIONS
CAUTION
Installation
If the refrigerant gas leaks during the
installation, ventilate the area immediately.
• Such leakage it can be harmful for your
health.
Always check for gas (refrigerant) leakage
after installation or repair of product.
• Low refrigerant levels may cause product
failure.
Keep the product level, even when installing it.
• This will help to avoid vibration or water
leakage.
Use two or more people to lift and transport
the product.
• This will help to avoid personal injury.
Installation work must be performed in
accordance with the National Electric Code by
qualified and authorized personnel only.
Do not place objects in direct proximity of
the outside unit. Do not let leaves and other
debris accumulate around the unit. Leaves are
a hotbed for small animals, which can enter
the unit. Once inside the unit, these animals
can lead to the unit malfunctioning, and end
up causing in smoke or fire when they make
contact with electrical parts.
• There is a risk of fire or electric shock.
Do not install the product where it will be
exposed to sea wind (salt spray) directly.
• This can cause corrosion on the product.
Corrosion, particularly on the condenser
and evaporator fins, could cause product
malfunction or inefficient operation.
Make sure that the drainpipe is installed
properly to drain water. Arrange the drain hose
to ensure smooth drainage.
• Incomplete drainage may lead to water
damage done to the building, furniture, etc.
If no water is discharged from the drainpipe
while the air conditioner or heat pump is in
the cooling mode, it may be because the
drainpipe has become clogged with dust
or dirt, and could result in water leakage

specified refrigerant used in the system.
• Air entering the refrigerant system can
lead to excessively high pressure causing
equipment damage or injury.
Make sure that there are no obstacles close
to the outdoor unit. The presence of obstacles
close to the outdoor unit may reduce the
performance of outdoor unit or increase its
operating sound.
• This could cause product failure.
Do not use the air conditioner for any other
purposes other than comfort cooling or
heating. Do not use the unit for cooling
precision instruments, food, plants, animals or
