2	TIPS FOR SAVING ENERGY

TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize the power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions below:

•Do not cool excessively indoors. This may be harmful for your health and may consume more electricity.

•Block sunlight with blinds or curtains while you are operating the air conditioner.

•Keep doors or windows closed tightly while you are operating the air conditioner.

•Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

•Speed up the fan to cool or warm indoor air quickly, in a short period of time.

•Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.

•Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

function 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.

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 product.

-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 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 equipped.)

-There is risk of physical injury, electric shock, or product failure.

IMPORTANT SAFETY INSTRUCTIONS	5

! CAUTION

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 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.

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.

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.

• 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.
