Safety Precautions
ENGLISH
• Installation or repairs made by unqualified per-
sons can result in hazards to you and othersIn-
stallation of all field wiring and components
MUST conform with local building codes or, in the
absence of local codes, with the National Electri-
cal Code 70 and the National Building Con-struc-
tion and Safety Code or Canadian Electrical code
and National Building Code of Canada.
• Installation or repairs made by unqualified per-
sons can result in hazards to you and others.
• The information contained in the manual is
intended for use by a qualified service technician
familiar with safety procedures and equipped with
the proper tools and test instruments.
• Failure to carefully read and follow all instructions
in this manual can result in equipment malfunc-
tion, property damage, personal injury and/or
death.
Installation
• Have all electric work done by a licensed electri-
cian 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 or fire may result.
• Ask the dealer or an authorized technician to
install the air conditioner.
- Improper installation by the user may result in
water leakage, electric shock, or fire.
• Always ground the product.
- There is risk of fire or electric shock.
• Always intstall a dedicated circuit and breaker.
- Improper wiring or installation may cause fire or
electric shock.
• For re-installation of the installed product, always
contact a dealer or an Authorized Service Center.
- There is risk of fire, electric shock, explosion, or
injury.
• Do not install, remove, or re-install the unit by
yourself (customer).
- There is risk of fire, electric shock, explosion, or
injury.
• Do not store or use flammable gas or com-
bustibles near the air conditioner.
- There is risk of fire or failure of product.

Safety Precautions
• Do not install the product on a defective installa-
tion stand.
- It may cause injury, accident, or damage to the
product.
• Use a vacuum pump or Inert(nitrogen) gas when
doing leakage test or air purge. Do not compress
air or Oxygen and do not use Flammable gases.
Otherwise, it may cause fire or explosion.
- There is the risk of death, injury, fire or explo-
sion.
• When installing and moving the air conditioner to
another site, do not charge it with a different
refrigerant from the refrigerant 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.
• Do not reconstruct to 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
LGE are used, fire or explosion may result.
• Ventilate before operating air conditioner when
gas leaked out.
- It may cause explosion, fire, and burn.
• Securely install the cover of control box and the
panel.
- If the cover and panel are not installed securely,
dust or water may enter the outside unit and
fire or electric shock may result.
• If the air conditioner is installed in a small room,
measures must be taken to prevent the refriger-
ant 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, harzards
due to lack of oxygen in the room could result.
Operation
• Do not damage or use an unspecified power
cord.
- There is risk of fire, electric shock, explosion, or
injury.
• Use a dedicated outlet for this appliance.
- There is risk of fire or electrical shock.
• Be cautious that water could not enter the prod-
uct.
- There is risk of fire, electric shock, or product
damage.
• Do not touch the power switch with wet hands.
- There is risk of fire, electric shock, explosion, or
injury.
• When the product is soaked (flooded or sub-
merged), contact an Authorized Service Center.
- There is risk of fire or electric shock.
• Be cautious not to touch the sharp edges when
installing.
- It may cause injury.
• Take care to ensure that nobody could step on or
fall onto the outside unit .
- This could result in personal injury and product
damage.
• Do not open the inlet grille of the product during
operation. (Do not touch the electrostatic filter, if
the unit is so equipped.)
- There is risk of physical injury, electric shock, or
product failure.
Installation
• Always check for gas (refrigerant) leakage
after installation or repair of product.
- Low refrigerant levels may cause failure of
product.
• Do not install the product where the noise or
hot air from the outside unit could damage
the neighborhoods.
- It may cause a problem for your neighbors.
• Keep level even when installing the product.
- To avoid vibration or water leakage.
• Do not install the unit where combustible gas
may leak.
- If the gas leaks and accumulates around the
unit, an explosion may result.
• Use power cables of sufficient current carrying
capacity and rating.
- Cables that are too small may leak, generate
heat, and cause a fire.

Installation Manual 5
Safety Precautions
ENGLISH
• Do not use the product for special purposes,
such as preserving foods, works of art, etc. It
is a consumer air conditioner, not a precision
refrigeration system.
- There is risk of damage or loss of property.
• When installting the unit in a hospital, commu-
nication station, or similar place, provide suffi-
cient protection against noise.
- The inverter equipment, private power gener-
ator, high-frequency medical equipment, or
radio communication equipment may cause
the air conditioner to operate erroneously, or
fail to operate. On the other hand, the air
conditioner may affect such equipment by
creating noise that disturbs medical treat-
ment or image broadcasting.
Operation
• Do not use the air conditioner in special envi-
ronments.
- Oil, steam, sulfuric smoke, etc. can signifi-
cantly reduce the performance of the air con-
ditioner or damage its parts.
• Do not block the inlet or outlet.
- It may cause failure of appliance or accident.
• Make the connections securely so that the out-
side force of the cable may not be applied to
the terminals.
- Inadequate connection and fastening may
generate heat and cause a fire.
• Be sure the installation area does not deterio-
rate with age.
- If the base collapses, the air conditioner
could fall with it, causing property damage,
product failure, or personal injury.
• Install and insulate the drain hose to ensure
that water is drained away properly based on
the installation manual.
- A bad connection may cause water leakage.
• Be very careful about product transportation.
- Only one person should not carry the prod-
uct if it weighs more than 20 kg.
- Some products use PP bands for packaging.
Do not use any PP bands for a means of
transportation. It is dangerous.
- Do not touch the heat exchanger fins. Doing
so may cut your fingers.
- When transporting the outside unit , sus-
pending it at the specified positions on the
unit base. Also support the outside unit at
four points so that it cannot slip sideways.
• 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 may not play with
them. If children play with a plastic bag
which was not torn apart, they face the risk
of suffocation.
• Turn on the power at least 6 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 opera-
tional season.
• Do not touch any of the refrigerant piping dur-
ing and after operation.
- It can cause a burn or frostbite.
• Do not operate the air conditioner with the
panels or guards removed.
- Rotating, hot, or high-voltage parts can
cause injuries.
• Do not directly turn off the main power switch
after stopping operation.
- Wait at least 5 minutes before turning off the
main power switch. Otherwise it may result in
water leakage or other problems.
• Auto-addressing should be done in condition
of connecting the power of all indoor and out-
doour units. Auto-addressing should also be
done in case of changing the indoor unit PCB.
• Use a firm stool or ladder when cleaning or
maintaining the air conditioner.
- Be careful and avoid personal injury.
