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.

Limiting concentration: 0.44 kg/m3(R410A)

Total amount of replenished refrigerant

Refrigerant concentration(kg/m3) =

in refrigerant facility (kg)

Capacity of smallest room

where indoor unit is installed (m3)

IMPORTANT SAFETY INSTRUCTIONS

ENGLISH

READ ALL INSTRUCTIONS BEFORE USING THE APPLIANCE.

Always comply with the following precautions to avoid dangerous situations and ensure peak
performance of your product.

WARNING

!

It can result in serious injury or death when the directions are ignored.

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.

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.

• 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.

• 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.

- 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.

• Do not damage or use an unspecified power cord.

• Use a dedicated outlet for this appliance.

• Be cautious that water could not enter the product.

• Do not touch the power switch with wet hands.

• When the product is soaked (flooded or submerged), contact an Authorized Service Center.

• Be cautious not to touch the sharp edges when installing.

• Take care to ensure that nobody could step on or fall onto the outdoor unit.

• Do not open the inlet grille of the product during operation. (Do not touch the electrostatic filter, if the unit

• Take care to ensure that power cable could not be pulled out or damaged during operation. There is risk

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.

CAUTION

!

Installation

• If anyone other than a licensed Professional installs, repairs, or alters LG Electronics Air Conditioning
Products, the warranty is voided.

- All costs associated with repair are then the full responsibility of the owner.

• 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

- 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.
