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.
For use in Europe:
This appliance can be used by children aged from 8 years and above

EN
• 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.
• Keep any required ventilation openings clear of obstruction. (for R32)
• Means for disconnection must be incorporated in the fixed wiring in
accordance with the wiring rules.
• Do not install the unit in potentially explosive atmospheres.
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.

• 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.

OPERATION
Notes for Operation
Suggestion for Energy Saving
• Do not over-cool the space. 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.
