to persons when using this product, follow basic precautions, including the following:

• Before accessing the terminals, all power circuits must be disconnected.

• Fixed installations will incorporate disconnect means in accordance with installation rules.

• The appliance must be installed in accordance with national regulations for electrical installations.

Children in the Household

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.

IMPORTANT SAFETY INSTRUCTIONS

WARNING

To reduce the risk of explosion, re, death, electric shock, injury or scalding

to persons when using this product, follow basic precautions, including the following:

Installation

• Do not install the air conditioner on an unstable surface or in a place where there is danger of it falling.

• Contact an authorized service center when installing or relocating the air conditioner.

• Install the panel and the cover of the control box safely.

• Do not install the air conditioner in a place where ammable liquids or gases such as gasoline, propane, paint thinner, etc., are stored.

• Make sure that the pipe and the power cable connecting the indoor and outdoor units are not pulled too tight when installing the air conditioner.

• Use standard circuit breaker and fuse that conform to the rating of the air conditioner.

• Do not input air or gas into the system except with the specic refrigerant.

• Use non-ammable gas (nitrogen) to check for leak and to purge air; using

compressed air or ammable gas may cause re or explosion.

• The 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 re.

• Install dedicated electric outlet and circuit breaker before using the air conditioner.

• Do not connect the ground wire to a gas pipe, a lightning rod, or a telephone ground wire.

ENGLISH

Operation

• Be sure to use only those parts listed in the service parts list. Never attempt to

modify the equipment.

• Make sure that children do not climb on or hit the outdoor unit.

• Dispose of the batteries in a place where there is no danger of re.

• Use only the refrigerant specied on the air conditioner label.

• Cut off the power supply if there is any noise, smell, or smoke coming from the air conditioner.

• Do not leave ammable substances such as gasoline, benzene, or thinner near the air conditioner.

• Contact an authorized service center when the air conditioner is submerged by

ood waters.

• Do not use the air conditioner for an extended period time in a small place without proper ventilation.

• In the event of a gas leak (such as Freon, propane gas, LP gas, etc.) ventilate

sufciently before using the air conditioner again.

• To clean the interior, contact an authorized service center or dealer. Using harsh detergents may cause corrosion or damage to the unit.

• Be sure to ventilate sufciently when the air conditioner and a heating appliance such as a heater are used simultaneously.

• Do not block the inlet or outlet of air ow.

• Do not insert hands or other objects through the air inlet or outlet while the air conditioner is operating.

• Make sure that the power cable is neither dirty, loose, nor broken.

• Never touch, operate, or repair the air conditioner with wet hands.

• Do not place any objects on the power cable.

• Do not place a heater or other heating appliances near the power cable.

• Do not modify or extend the power cable. Scratches or peeling insulation on the

power cables may result in re or electric shock, and should be replaced.

• Cut off the power supply immediately in the event of a blackout or a thunderstorm.

Maintenance

• Do not clean the appliance by spraying water directly onto the product.

• Before cleaning or performing maintenance, disconnect the power supply and wait until the fan stops.

Technical Safety

• Installation or repairs made by unauthorized persons can pose hazards to you and others.

• The information contained in the manual is intended for use by a qualied

service technician who is familiar with the 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.

• The appliance shall be installed in accordance with national wiring regulations.

• When the power cord is to be replaced, the replacement work shall be performed by authorized personnel using only genuine replacement parts.

• This appliance must be properly grounded to minimize risk of electric shock.

• 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, uninsulated, and the wall receptacle is grounded through house wiring.

• If you have any doubt whether the air conditioner is properly grounded, have the

wall receptacle and circuit checked by a qualied electrician.

• The refrigerant and insulation blowing gas used in the appliance require special disposal procedures. Consult a service agent or a similarly qualied person

before disposing of them.

• If the supply cord is damaged, it must be replaced by the manufacturer or its

service agents or similarly qualied person in order to avoid a hazard.

ENGLISH

CAUTION

To reduce the risk of minor injury to persons, malfunction, or damage to the product or property when using this product, follow basic precautions, including the following:

Installation

• Do not install the air conditioner in an area where it is directly exposed to sea wind(salt spray).

• Install the drain hose properly for the smooth drainage of water condensation.

• Exercise caution when unpacking or installing the air conditioner.

• Do not touch the leaking refrigerant during installation or repair.

• Transport the air conditioner with two or more people or use a forklift.

• Install the outdoor unit such that it is protected from direct sunlight. Do not place the indoor unit in a place where it is directly exposed to sunlight via the windows.

• Safely dispose of packing materials such as screws, nails or batteries using proper packaging after installation or repair.

• Install the air conditioner in a place where the noise from the outdoor unit or the exhaust fumes will not inconvenience the neighbors. Failure to do so may result

in conict with the neighbors.

Operation

• Remove the batteries if the remote control is not to be used for an extended period of time.

• Make sure that the lter is installed before operating the air conditioner.

• Be sure to check if there is a refrigerant leak after installing or repairing the air conditioner.

• Do not place any object on the air conditioner.

• Never mix different types of batteries, or old and new batteries for the remote control.

• Do not let the air conditioner run for a long time when humidity is very high or when a door or a window has been left open.

• Stop using the remote control if there is a uid leak in the battery. If your clothes or skin are exposed to the leaking battery uid, wash off with clean water.

• Do not expose people, animals, or plants to the cold or hot wind from the air conditioner for extended periods of time.

• If the leaking battery uid has been swallowed, wash off the inside of the mouth thoroughly and consult a doctor.

• Do not drink the water drained from the air conditioner.

• Do not use the product for special purposes, such as preserving foods, works of art, and etc. It is an air conditioner for consumer purposes, not a precision refrigeration system. There is risk of damage or loss of property.

• Do not recharge or disassemble the batteries.

Maintenance

• Never touch the metal parts of the air conditioner when removing the air lter.

• Use a sturdy stool or ladder when cleaning, maintaining, or repairing the air conditioner at a height.

• Never use strong cleaning agents or solvents when cleaning the air conditioner or spray water. Use a smooth cloth.

OPERATION

Notes for Operation

Suggestion for Energy Saving

• 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 ow vertically or horizontally to circulate indoor air.
