2	TIPS FOR SAVING ENERGY

TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize power consumption when you use your air conditioner.

•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 indoor air quickly.

•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.

4	IMPORTANT SAFETY INSTRUCTIONS

READ ALL INSTRUCTIONS BEFORE USING THE APPLIANCE.

•Do not place a heater or other heating appliances near the power cable. It may result in fire, electric shock, or 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.

Installation

•Do not install the air conditioner on an unstable surface or where there may be a danger of it falling. It may result in death, serious injury, or product failure.

•Contact an authorized service center when you install or relocate the air conditioner. Failure to do so may result in serious injury or product failure.

•Indoor/outdoor wiring connections must be secured tightly, and the cable should be routed properly so that there is no force pulling the cable from the connection terminals. Improper or loose connections can cause heat generation or fire.

•Install the panel and the cover of the control box safely. Failure to do so may result in explosion or fire.

•Do not install the air conditioner where flammable liquids or gases such as gasoline, propane, paint thinner, etc. are stored. It may result in explosion or fire.

•Make sure that the pipe and the power cable that connect the indoor unit and the outdoor unit are not pulled tight when you install the air conditioner. Failure to do so may result in electric shock or product failure.

•Do not mix air or gas in the system except for the specific refrigerant. If air enters the refrigerant system, it may result in an excessively high pressure that causes injury or damage to the equipment.

Use

•Be sure to use only those parts which are listed in the service parts list. Never attempt to modify the equipment. It may result in death, serious injury, or product failure.

•Do not pull the power cord when you remove the power plug. It may result in death or electric shock.

•Discard the batteries where there is no danger of fire. Failure to do so may result in explosion or fire.

•Contact a qualified HVAC technician when the air conditioner is submerged in water due to flooding. Failure to do so may result in death, explosion, or fire.

•Only use components that are approved by the manufacturer and do not repair or modify them. Failure to do so may result in electric shock or product failure.

•Only use the refrigerant specified on the air conditioner label. Failure to do so may result in explosion or fire.

•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 proper ventilation. It may result in explosion or fire.

•Do not touch the electrostatic filter after opening the front grille. It may result in electric shock or product failure.

•For inner cleaning, contact a qualified HVAC technician or a dealer.

Using harsh detergents may cause corrosion or damage to the unit and may lead to product failure, fire, or electric shock.

IMPORTANT SAFETY INSTRUCTIONS	5

READ ALL INSTRUCTIONS BEFORE USING THE APPLIANCE.

•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.

•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.

•Make sure that children do not climb on or hit the outdoor unit. Failure to do so may result in death or product failure.

•Do not turn the air conditioner on or off by plugging in or unplugging the power plug. It may result in fire or electric shock.

•If there is a gas or Freon leak, ventilate sufficiently before using the air conditioner again. Failure to do so may result in explosion or fire.

•Using the product for special purposes, such as preserving foods, works of art, etc. may result in death, fire, or electric shock. It is a consumer air conditioner, not a precision refrigeration system.

•Do not block the inlet or outlet of air flow. It may result in explosion or product failure.

•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 or serious injury.

•Do not expose people, animals, or plants to the cold or hot wind from the air conditioner for prolonged amounts of time. It may result in serious injury.

•Do not drink the water drained from the air conditioner. It may result in serious health complications.

Maintenance

! CAUTION

Installation

•Install the outdoor unit on the north side to prevent the outside unit from being in direct sunlight. Do not place the indoor unit in direct sunlight from windows. Excessive sunlight may result in product failure.

•Safely dispose of packing materials such as screws, nails or batteries in a packing bag after installation or repair. 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.

•Install the drain hose properly for smooth drainage of condensed water. Failure to do so may result in product failure.

•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.

•Be cautious when you unpack or install the air conditioner. Failure to do so may result in serious injury or product failure.

•Do not touch the refrigerant leakage during installation or repair. It may result in product failure.
