IMPORTANT SAFETY INSTRUCTIONS
WARNING
To reduce the risk of explosion, fire, 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 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.

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 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 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.
••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 or water pipe or any internal parts while the unit is
operation or immediately after operation.

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 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 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.

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 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.
7
••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, 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 filter.
••Use a sturdy stool or ladder when cleaning, maintaining, or repairing the air
conditioner at a height.

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 flow vertically or horizontally to circulate indoor air.
•• Speed up the fan to cool or warm indoor air quickly, within a short period of time.
•• Open windows regularly for ventilation. The indoor air quality may deteriorate if the air conditioner is used for
long durations.
•• 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.
