TIPS FOR SAVING ENERGY

ENGLISH

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.

• The information contained in the manual is intended for use by a qualified service technician familiar with safety procedures and equipped with the proper tools and test instruments.

• Failure to read and follow all instructions in this manual can result in equipment malfunction, property damage, personal injury and/or death.

Power

• Unplug the power plug immediately in the event of a blackout or thunderstorm. Failure to do so may result in fire or electric shock.

• Always use a power plug and socket with a ground terminal. Failure to do so may result in electric shock or product failure.

• Install a dedicated electric outlet and circuit breaker before you use the air conditioner. Failure to do so may result in electric shock or product failure.

• Do not connect the ground wire to a gas pipe, a lightning rod or a telephone ground wire. It may result in electric shock or product failure.

• Use a standard circuit breaker and fuse conforming with the rating of the air conditioner. Failure to do so may result in electric shock or product failure.

• Make sure to check that the power cable plug is not dirty, loose or broken and then only insert the plug completely. It may result in electric shock or product failure.

• Do not modify or extend the power cable. If the power cable or cord has scratches or skin peeled off or deteriorated then it must be replaced. It may result in fire or electric shock.

• Don’t use a power cord, a plug or a loose socket which is damaged. It may result in fire or electric shock.

ENGLISH

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 flood-

ing. 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 explo-

sion 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 venti-

lation. 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.

consult a doctor. Failure to do so may result in serious health complications.

• 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. It may result in product failure.

• Do not use the product for special purposes,such as preserving foods, works of art, etc. It is a con-

sumer air conditioner, not a precision refrigeration system. There is risk of damage or loss of property.

Maintenance
