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 flammable 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 specific refrigerant.

• Use non-flammable gas (nitrogen) to check for leak and to purge air; using compressed air or

flammable gas may cause fire 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 fire.

• 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.

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 fire.

• Use only the refrigerant specified 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 flammable substances such as gasoline, benzene, or thinner near the air

conditioner.

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

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

ventilation.

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

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 sufficiently when the air conditioner and a heating appliance such as a

heater are used simultaneously.

• Do not block the inlet or outlet of air flow.

• 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.

EN

• 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 fire or electric shock, and should be replaced.

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

• Take care to ensure that power cable could not be pulled out or damaged during operation.

• Do not touch refrigerant pipe, water pipe and any internal parts while the unit is operating or

immediately after operation.

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 qualified 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 earth wire to the power outlet cover screw does not ground the appliance unless

the cover screw is metal, uninsulated, and the power outlet is grounded through house wiring.

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

and circuit checked by a qualified electrician.

• The refrigerant and insulation blowing gas used in the appliance require special disposal

procedures. Consult a service agent or a similarly qualified person before disposing of them.

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

similarly qualified person in order to avoid a hazard.

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 conflict 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 filter 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 fluid leak in the battery.

If your clothes or skin are exposed to the leaking battery fluid, 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 fluid has been swallowed, rinse 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

cadmium (Cd) or lead (Pb) if the battery contains more than 0.0005 % of

mercury, 0.002 % of cadmium or 0.004 % of lead.

• All batteries/accumulators should be disposed separately from the

municipal waste stream via designated collection facilities appointed by the

government or the local authorities.

• The correct disposal of your old batteries/accumulators will help to prevent

potential negative consequences for the environment, animal and human

health.

• For more detailed information about disposal of your old

batteries/accumulators, please contact your city office, waste disposal

service or the shop where you purchased the product.
