• 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.

INTRODUCTION
ENGLISH
Install the drain hose to ensure that water is drained away properly. A bad connection may cause
water leakage.
Keep level even when installing the product. To avoid vibration or water leakage.
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.
Use two or more people to lift and transport the product. Avoid personal injury.
Do not install the product where it will be 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 expose the skin directly to cool air for long periods of time. (Don't sit in the draft.) This could
harm to your health.
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.
Do not block the inlet or outlet of air flow. It may cause product failure.
Use a soft cloth to clean. Do not use harsh detergents, solvents, etc. There is risk of fire, electric
shock, or damage to the plastic parts of the product.
Do not touch the metal parts of the product when removing the air filter. They are very sharp! There
is risk of personal injury.
Do not step on or put anyting on the product. (outdoor units) There is risk of personal injury and
failure of product.
Always insert the filter securely. Clean the filter every two weeks or more often if necessary. A dirty
filter reduces the efficiency of the air conditioner and could cause product malfunction or damage.
Do not insert hands or other objects through the air inlet or outlet while the product is operated.
There are sharp and moving parts that could cause personal injury.
Do not drink the water drained from the product. It is not sanitary and could cause serious health
issues.
Use a firm stool or ladder when cleaning or maintaining the product. Be careful and avoid personal
injury.
Replace the all batteries in the remote control with new ones of the same type. Do not mix old and
new batteries or different types of batteries. There is risk of fire or explosion
Do not recharge or disassemble the batteries. Do not dispose of batteries in a fire. They may burn or
explode.
If the liquid from the batteries gets onto your skin or clothes, wash it well with clean water. Do not
use the remote if the batteries have leaked. The chemicals in batteries could cause burns or other health hazards.
• If you eat the liquid from the batteries, brush your teeth and see doctor. Do not use the remote if
the batteries have leaked. The chemicals in batteries could cause burns or other health hazards.
• 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.
• The sound pressure of this product is below 70 dB.
• The noise level can vary depending on the site.

• The above list indicates the order in which the individual work operations are normally carried out but this order may be varied where local conditions warrants such change.
• The wall thickness of the pipe should comply with the relevant local and national regulations for the designed pressure 3.8 MPa.
• Since R-410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state.(If the refrigerant is charged in its gaseous state, its composition changes and the system will not work properly.)

- The refrigerant R-410A has the property of higher operating pressure in comparison with R22. Therefore, all materials have the characteristics of higher resisting pressure than R22 ones and this characteristic should be also considered during the installation. R-410A is an azeotrope of R32 and R125 mixed at 50:50, so the ozone depletion potential (ODP) of R-410A is 0. These days the developed countries have approved it as the environment-friendly refrigerant and encouraged to use it widely to prevent environment pollution.
• The wall thickness of the pipe should comply with the relevant local and national regulations for the designed pressure 3.8 MPa
• Since R-410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state. If the refrigerant is charged in its gaseous state, its composition changes and the system will not work properly.
• Do not place the refrigerant container under the direct rays of the sun to prevent it from exploding.
• For high-pressure refrigerant, any unapproved pipe must not be used.
• Do not heat pipes more than necessary to prevent them from softening.
• Be careful not to install wrongly to minimize economic loss because it is expensive in comparison with R22.

INSTALLATION PLACE
ENGLISH
Selecting the location(Outdoor Unit)
If the outdoor unit is to be installed close to the seaside, direct exposure to the sea wind should be avoided. Install the outdoor unit on the opposite side of the sea wind direction.
In case, to install the outdoor unit on the seaside, set up a windbreak not to be exposed to the sea wind.
- It should be strong enough like concrete to prevent the sea wind from the sea.
- The height and width should be more than 150 % of the outdoor unit.
- It should be keep more than 70 cm of space between outdoor unit and the windbreak for easy air flow.
Place with fluent water draining
- Install at a place with fluent water draining to prevent damage from localized heavy rain and avoid frequent flooded area.

• Air conditioners should not be installed in areas where corrosive gases, such as acid or alkaline gas, are produced.
• Do not install the product where it could be exposed to sea wind (salty wind) directly. It can result corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient performance.
• If outdoor unit is installed close to the seaside, it should avoid direct exposure to the sea wind. Otherwise it needs additional anticorrosion treatment on the heat exchanger.
CAUTION
!
Installation guide at the seaside
• If you can’t meet above guide line in the seaside installation, please contact LG Electronics for the additional anticorrosion treatment.
• Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on the heat exchanger by using water
