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:
• 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.

Operation
• Do not let the air conditioner run for a long time when the humidity is very high or when a door or
window has been left open. Failure to do so may result in product failure.
• Make sure that the power cord is not pulled or damaged while the air conditioner is operating. Failure to do so may result in fire, electric shock, or product failure.
• Do not place any objects on the power cord. It may result in electric shock or product failure.
• Do not turn on or off the air conditioner by plugging in or unplugging the power plug. It may result in
fire or electric shock.
• Do not touch, operate or repair the air conditioner with wet hands. It may result in electric shock or
product failure.
• Do not place a heater or other heating appliances near the power cable. It may result in fire, electric
shock, or product failure.
• Do not allow water to run into the air conditioner. It may result in explosion or fire.
• Do not leave flammable substances such as gasoline, benzene and thinner near the air conditioner.
It may result in explosion or fire.
• Do not use the air conditioner for an extended period of time in a small place without ventilation.
Ventilate the place regularly. Failure to do so may result in explosion or fire.
• When there is a gas leak, ventilate sufficiently before using the air conditioner again. Failure to do so
may result in explosion or fire.
• Unplug the power plug if there is a noise, smell or smoke coming from the air conditioner. Failure to
do so may result in explosion or fire.
• Stop operating and close the window in strom or hurricane.If possible remove the product from the
window before hurricane arrives
• Do not touch the electrostatic filter after opening the front grille. Failure to do so may result in electric shock or product failure.
• Contact an authorized service center when the air conditioner is submerged into water due to flooding. Failure to do so may result in explosion or fire.
• Be cautious water could not enter the product
• Make sure to ventilate sufficiently when this air conditioner and a heating appliance such as a heater
are used simultaneously. Failure to do so may result in fire, serious injury, or product failure.
• Turn the main power off and unplug the power plug when you clean or repair the air conditioner.
Failure to do so may result in death, serious injury, or product failure.
• Unplug the power plug when the air conditioner is not used for an extended period of time. Failure
to do so may result in product failure.
• Do not place any objects on the air conditioner. It may result in product failure.
• For inner cleaning, contact an Authorized Service Center or a dealer.
Do not use harsh detergent that causes corrosion or damage on the unit.
Harsh detergent may also cause failure of product, fire, or electronic shock.
SAFETY PRECAUTIONS
5
• Make sure to check if there is a refrigerant leak after you install or repair the air conditioner. Failure
to do so may result in product failure.
• Install the drain hose properly for smooth drainage of condensed water. Failure to do so may result
in product failure.
• Keep level even when installing the product.
• Install the air conditioner where the noise from the outdoor unit or the exhaust gas will not inconvenience the neighbors. Failure to do so may result in conflict between neighbors.
• When transporting the equipment, there should be at least 2 or more people, or a forklift. It may result in serious injury.
• Do not install the air conditioner where it will be exposed to sea wind (salt spray) directly. It may result in product failure.
Operation
• Do not expose people, animals or plants to the cold or hot wind from the air conditioner. It may result in serious injury.
• 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. It may result in death, fire or electric
shock.
• Do not block the inlet or outlet of air flow. It may result in explosion or product failure.
• Do not use strong cleaning agents or solvents when you clean the air conditioner, or spray water.
Use a smooth cloth. It may result in serious injury or product failure.
• Never touch the metal parts of the air conditioner when you remove the air filter. It may result in serious injury or product failure.
• Do not place any objects on the air conditioner. It may result in product failure.
• Always insert the filter securely after cleaning. Clean the filter every two weeks or more often if
necessary.
• Do not insert hands or other objects through the air inlet or outlet while the air conditioner is operating. It may result in electric shock.
• Do not drink the water drained from the air conditioner. It may result in serious health complications.
• Use a sturdy stool or ladder when you clean, maintain or repair the air conditioner at a height. Failure
to do so may result in serious injury or product failure.
• Do not mix the batteries for the remote control with other types of batteries or mix new batteries
with used batteries. Failure to do so may result in product failure.
• Do not recharge or disassemble the batteries. Failure to do so may result in explosion, fire or serious
injury.
• Stop using the remote control if there is a battery fluid leak. If your cloth or skin is exposed to the
battery fluid from a leak, wash it off with clean water. Failure to do so may result in serious injury.
• If you swallow the battery fluid from a leak, wash out the inside of your mouth thoroughly and then
consult a doctor. Failure to do so may result in serious health complications.
