Safety Precautions
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.

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, 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.
Be cautious that water could not enter the product.
•There is risk of fire, electric shock, or product damage.
Take care so that children should not randomly operate the wire remote control for play.

Safety Precautions
■ Installation
Always check for gas (refrigerant) leakage after installation or repair of product.
Do not install the product where the noise or hot air from the outdoor unit could damage the neighborhoods.
•Low refrigerant levels may cause failure of product.
Keep level even when installing the product.
•It may cause a problem for your neighbors.
Do not install the unit where combustible gas may leak.
•To avoid vibration or water leakage.
Use power cables of sufficient current carrying capacity and rating.
•If the gas leaks and accumulates around the unit, an explosion may result.
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.
•Cables that are too small may leak, generate heat, and cause a fire.
Keep the unit away from children. The heat exchanger is very sharp.
•There is risk of damage or loss of property.
When installting the unit in a hospital, communication station, or similar place, provide sufficient protection against noise.
•It can cause the injury, such as cutting the finger. Also the damaged fin may result in degradation of capacity.
•The inverter equipment, private power generator, high-frequen- cy 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 treatment or image broadcasting.
Do not install the product where it is exposed to sea wind (salt spray) directly.
•It may cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient operation.
■ Operation
Do not use the air conditioner in special environments.
Do not block the inlet or outlet.
• Oil, steam, sulfuric smoke, etc. can significantly reduce the |
• It may cause failure of appliance or accident. |
performance of the air conditioner or damage its parts. |
|
Make the connections securely so that the outside 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 deteriorate with age.
•If the base collapses, the air conditioner could fall with it, causing property damage, product failure, and 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.

Safety Precautions
Be very careful about product transportation.
• Only one person should not carry the product 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. |
<![if ! IE]> <![endif]>ENGLISH |
|
• When transporting the outdoor unit, suspending it at the specified positions on the unit base. Also support the outdoor 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.(In case of outdoor
temperature below 10°C)
•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 any of the refrigerant piping during and after operation.
•It can cause a burn or frostbite.
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.
Use a firm stool or ladder when cleaning or maintaining the air conditioner.
•Be careful and avoid personal injury.
Do not operate the air conditioner with the panels or guards removed.
•Rotating, hot, or high-voltage parts can cause injuries.
Auto-addressing should be done in condition of connecting the power of all indoor and outdoor units. Autoaddressing should also be done in case of changing the Indoor unit PCB.
Do not insert hands or other objects through the air inlet or outlet while the air conditioner is plugged in.
•There are sharp and moving parts that could cause personal injury.
Avoid a place where rain may enter since the HR unit is for indoor
•There is risk of property damage, failure of product or electric shock.
Install the HR unit at a place in which it is not affected by operation mode changing noise.
•Installation within cell such as meeting room etc, may disturb business due to noise.
