TIPS FOR SAVING ENERGY
ENGLISH
• Do not cool excessively indoors. This may be harmful to 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.

• Do not use a defective or underrated circuit breaker. Use the correctly rated breaker and fuse. There is risk of fire or electric shock.
• For electrical work, contact the dealer, seller, a qualified electrician, or an Authorized Service Center. Do not disassemble or repair the product by yourself. There is risk of fire or electric shock.
• Always ground the product as per the wiring diagram. Do not connect the ground wire to gas or water pipes lightening rod or telephone ground wire. There is risk of fire or electric shock.
• Install the panel and the cover of control box securely. There is risk of fire or electric shock due to dust , water etc.
• Use the correctly rated breaker or fuse. There is risk of fire or electric shock.
• Do not modify or extend the power cable. If the power cable or cord has scrathes or skin peeled off or deteriorated then it must be replaced. There is risk of fire or electric shock.
• For installation, removal or reinstall , always contact the dealer or an Authorized Service Center. There is risk of fire, electric shock, explosion, or injury.
• Do not install the product on a defective installation stand. Be sure that the installation area does not deteriorate with age. It may cause product to fall.
• Never install the outdoor unit on a moving base or a place from where it can fall down. The falling outdoor unit can cause damage or injury or even death of a person.
• In outdoor unit the step-up capacitor supplies high voltage electricity to the electrical components. Be sure to discharge the capacitor completely before conducting the repair work. An charged capacitor can cause electrical shock.
• When installing the unit, use the installation kit provided with the product. Otherwise the unit may fall and cause severe injury.

• Always check for gas (refrigerant) leakage after installation or repair of product. Low refrigerant levels may cause failure of product.
• Please install safely at a place that can sufficiently endure the weight of the product. (If the strength is not sufficient, the product may fall and cause injury.)
Operation
• 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 or splashing water 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. There is risk of personal injury.
• Do not step on or put anything on the product. (outdoor units) There is risk of personal injury and failure of product.
• Always insert the filter securely after cleaning. Clean the filter every two weeks or more often if necessary. A dirty filter reduces the efficiency.
• Do not insert hands or other objects through the air inlet or outlet while the product is operating. There are sharp and moving parts that could cause personal injury.
• Be cautious when unpacking and installing the product. Sharp edges could cause injury.
• If the refrigerant gas leaks during the repair, do not touch the leakaing refrigerant gas. The refrigernat gas can cause frostbite (cold burn).
• Do not tilt the unit when removing or uninstalling it. The condensed water inside can spill.
• Do not mix air or gas other than the specified refrigerant used in the system. If air enters the refrigerant system, an excessively high pressure results, causing equipment damage or injury.
• If the refrigerant gas leaks during the installation, ventilate the area immediately. Otherwise it can be harmfull for your health.
• Dismantling the unit, treatment of the refrigerant oil and eventual parts should be done in accordance with local and national standards.
• 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 product failure.
• Do not recharge or disassemble the batteries. Do not dispose off 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.
• Do not let the air conditioner run for a long time when the humidity is very high and a door or a window is left open. Moisture may condense and wet or damage furniture.
• Do not expose your skin or kids or plants to the cool or hot air draft. This could harm to your health.
• 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, maintaining or repairing the product at an height. Be careful and avoid personal injury.

INSTALLATION OF INDOOR, OUTDOOR UNIT
ENGLISH
Read completely, then follow step by step. You need to select adequate installation location considering the following conditions, and make sure to acquire the consent of the user.
Select the best location
1
Do not have any heat or steam near the unit.
2 Select a place where there are no
obstacles in front of the unit.
3 Make sure that condensation drainage can
be conveniently routed away.
4 Do not install near a doorway. 5
Ensure the spaces indicated by arrows from the wall, ceiling, fence or other obstacles.
6 Use a stud finder to locate studs to
prevent unnecessary damage to the wall.
If an awning is built over the unit to prevent
direct sunlight or rain exposure, make sure that heat radiation from the condenser is not restricted.
Ensure that the spaces indicated by arrows
around front, back and side of the unit.
Do not place animals and plants in the path
of the warm air.
Take the air conditioner weight into account
and select a place where noise and vibration are minimum.
Select a place so that the warm air and noise from the air conditioner do not disturb neighbors.
• Place that can sufficiently endure the weight and vibration of the outdoor unit and where even installation is possible.
Place that has no direct influence of snow or rain.
Place with no danger of snowfall or icicle drop.
• Place without weak floor or base such as decrepit part of the building or with a lot of snow accumulation.
If the outdoor unit is installed on a roof structure, be sure to level the unit. Ensure the roof structure and anchoring method are adequate for the unit location. Consult local codes regarding rooftop mounting.
Install the indoor unit on the wall where the height from the floors more than 2.3 meters. (ART COOL Type Only 1.5 m)

Fixing Installation Plate
The wall you select should be strong and solid enough to prevent vibration
1 Mount the installation plate on the wall
with type "A" screws. If mounting the unit on a concrete wall, use anchor bolts.
- Mount the installation plate horizontally by aligning the centerline using a level.
<Type 1>
2 Measure the wall and mark the centerline.
It is also important to use caution concerning the location of the installation plate-routing of the wiring to power outlets is through the walls typically. Drilling the hole through the wall for piping connections must be done safely.
