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:
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
WARNING: Before accessing the terminals, all power circuits must be disconnected.
WARNING: Fixed installations will incorporate disconnect means in accordance with installation
rules.
WARNING: This device will not be accessible to public.
WARNING: The appliance must be installed in accordance with national regulations for electrical
installations.
• 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.

SAFETY PRECAUTIONS
CAUTION
• Two or more people must 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.
• Install the drain hose to ensure that the condensed water is drained away properly. A bad connection
may cause water leakage.
• Keep level even when installing the product. To avoid vibration or noise.
• Do not install the product where the noise or hot air from the outdoor unit could damage or disturb
the neighborhoods. It may cause a problem for your neighbors and hence dispute.
• Always check for gas (refrigerant) leakage after installation or repair of product. Low refrigerant levels
may cause failure of product.
• 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 anyting 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.

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.
• 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.
• 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.

ELECTRICAL SAFETY
WARNING
• This appliance must be properly grounded. To minimize the risk of electric shock, you must always
plug into a grounded outlet.
• Do not cut or remove the grounding prong from the power plug.
• Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the appliance unless the cover screw is metal and not insulated, and the wall receptacle is grounded through
the house wiring.
• If you have any doubt whether the air conditioner is properly grounded, have the wall receptacle and
circuit checked by a qualified electrician.
Temporary Use of an Adapter
We strongly discourage the use of an adapter due to potential safety hazards. For temporary connections, use only a genuine adapter, available from most local hardware stores. Ensure that the
large slot in the adapter is aligned with the large slot in the receptacle for a proper polarity connection.
To disconnect the power cord from the adapter, use one hand on each to avoid damaging the
ground terminal. Avoid frequently unplugging the power cord as this can lead to eventual ground
terminal damage.
WARNING
• Never use the appliance with a broken adapter.
Temporary Use of an Extension Cord
We strongly discourage the use of an extension cord due to potential safety hazards.
WARNING
• This appliance should be installed in accordance with national wiring regulations.
