IMPORTANT SAFETY INSTRUCTIONS

Airborne Noise Emission

The A-weighted sound pressure emitted by this product is below 70 dB.

The noise level can vary depending on the site.

The figures quoted are emission level and are not necessarily safe working levels.

Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required.

Factor that influence the actual level of exposure of the workforce include the characteristics of the work room and the other sources of noise, i.e. the number of equipment and other adjacent processes and the length of time for which an operator exposed to the noise. Also, the permissible exposure level can vary from country to country.

This information, however, will enable the user of the equipment to make a better evaluation of the hazard and risk.

Limiting concentration

Limiting concentration is the limit of Freon gas concentration where immediate measures can be taken without hurting human body when refrigerant leaks in the air. The limiting concentration shall be described in the unit of kg/m3(Freon gas weight per unit air volume) for facilitating calculation.

• 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 malfunction, property damage, personal injury and/or death.

• Compliance with national gas regulations shall be observed.

ENGLISH

SAFETY INSTRUCTIONS

Installation

• Have all electric work done by a licensed electrician 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.

• Compliance with national gas regulations shall be observed.

• 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.

• Ducts connected to an appliance shall not contain an ignition source. (for R32)

• Always install 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 combustibles near the air conditioner.

- There is risk of fire or failure of product.

• Use the correctly rated breaker or fuse.

- There is risk of fire or electric shock.

• Prepare for strong wind or earthquake and install the unit at the specified place.

- Improper installation may cause the unit to topple and result

in injury.

• Do not install the product on a non-parallel or defective installation 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.

SAFETY INSTRUCTIONS

- There is the risk of death, injury, fire or explosion.

• 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, hazards due to lack of oxygen in the room could result.

• The appliance shall be stored in a well-ventilated area where the room size corresponds to the room area as specified for operation. (for R32)

• The appliance shall be stored in a room without continuously operating ignition sources (for example: open flames, an operating gas appliance or an operating electric heater.)

• Keep any required ventilation openings clear of obstruction.

• Mechanical connections shall be accessible for maintenance purposes.

• To prevent the mixing of different types of refrigerants, be sure to check the type of refrigerant used in the outdoor unit.

- The mixing of refrigerants could lead to malfunctioning.
