• Do not touch the power switch with wet hands.
- There is risk of fire, electric shock, explosion, or injury.
• Take care so that children should not randomly operate the wire remote control for play.
- Frequent conversion to cold or heat mode may cause failure of the unit.
• When the product is soaked (flooded or submerged), 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 outdoor 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
- There is risk of physical injury, electric shock, or product failure.
• 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 outdoor 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 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.
• Don't use the existing manifold gage for R22 refrigerant.
- Use the manifold gage for high pressure (R410A) as possible as for stable refrigerant filling.
• Don't mix and use the R22 pipe and the installation appliances that were used until now
- Mixing the oil of R22 and R410A may cause
failure of the unit due to hydrolysis.
• 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 outdoor 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.
• 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.
• Keep the unit away from children. The heat exchanger is very sharp.
- It can cause the injury, such as cutting the finger. Also the damaged fin may result in degradation of capacity.
• When installting the unit in a hospital, communication station, or similar place, provide sufficient protection
against noise.
- The inverter equipment, private power generator, 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 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.
• Do not use the air conditioner in special environments.
- Oil, steam, sulfuric smoke, etc. can significantly reduce the performance of the air conditioner 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 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, 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 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.
- 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.
- 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 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 outdoour 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.
• 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.
