Installation Safety
SAFETY INSTRUCTIONS
•Do not install the air conditioner on an unstable surface or where
there is a danger of it falling; because it may result in death, serious
injury, and/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 and/
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
may 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 near a place with a danger of
explosion or fire; because it may result in serious bodily injury or
death.
•Do not install air conditioner with direct exposure to sea water or sea
wind (salt spray); because 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.
•Avoid exposure to leaking refrigerant which may occur during
Usage
•Ensure that the pipe and the power cable which connect the indoor
unit and the outdoor unit are not pulled tight when installing 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 excessively high pressure that may lead to personal injury or damage to the
equipment.
•Safely dispose of packing materials such as screws, nails or
batteries in a packing bag after installation or repair. Failure to do so
may result in serious bodily injury.
•Use caution when unpacking or installing the air conditioner. Failure
to do so may result in bodily injury or product failure.
•When lifting or transporting the equipment, there should be 2 or more
people, or a forklift. Failure to do so may result in bodily injury.
installation or repair. Failure to do so may result in personal injury
and/or product failure.
•If there is a refrigerant leak during the installation of the air
conditioner, ventilate the area immediately. Failure to do so may
result in serious injury and/or product failure.
Safety Instructions
•Use only those parts which are listed in the service parts list. Never
attempt to modify the equipment; because that may result in death,
serious injury, and/or product failure.
• Discard the batteries in a safe manner and where there is no danger
of excessive heat or fire. Failure to do so may result in explosion or
fire.
•Contact an authorized service center when the air conditioner is
submerged into water due to flooding. Failure to do so may result in
explosion or fire.
•Only use components that are approved by the manufacturer and
do not repair or modify them; because it may result in electric shock
and/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; because it may
result in explosion or fire.
•Do not leave flammable substances such as gasoline, benzene and
other white spirits or solvents, including thinner near the air conditioner; because it may result in explosion or fire and may result in
bodily injury.
•Do not use the air conditioner for an extended period of time in a
small place without ventilation; because it may result in explosion or
fire. Make sure to ventilate the space regularly.
•Do not touch the electrostatic filter after opening the front grill;
because it may result in electric shock or product failure.
•For inner cleaning, contact an authorized service center or a dealer.
Do not use harsh detergent that causes corrosion or damage on the
unit; because it may cause product failure, fire, and/or electronic
shock.
•Disconnect power if there is a noise, smell or smoke coming from the
air conditioner. Failure to do so may result in explosion or fire.
•Ventilate room or area when air conditioner and a heating appliance
such as a heater are used simultaneously. Failure to do so may result in fire, serious injury, and/or product failure.
•Make sure that children do not climb up the outdoor unit or impact
it. Failure to do so may result in death, bodily injury and/or product
failure.
•If there is a gas leak, ventilate area sufficiently before using the air
conditioner again. Failure to do so may result in explosion or fire.
•Do not use the product for special purposes, such as preserving
foods, works of art, etc.; because it may result in death, fire and/
or electric shock. The product is a consumer air conditioner, not a
precision refrigeration system.
•Do not block the inlet or outlet of air flow; because it may result
