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 the dealer. 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 deficiencyrelated accident may occur.
•• There is a risk of asphyxiation which could lead to serious injury or death.
Do not install the unit in an area where there are flammable materials.
•• There is 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.

•• 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.
Operation
If refrigerant gas leaks while the unit is being repaired do not touch the leakaing refrigerant gas.
•• The refrigernat gas can cause frostbite (cold burn)

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 in the indoor unit. In such a situation, stop operating the air conditioner or heat pump and contact the dealer.
