Safety precautions

Symbols in this Use and Care Manual are interpreted as shown below.

Be sure not to do.

The feature of the appliance,
instead of a fault.

Pay attention to such a situation.

Grounding is essential.

Be sure to follow this instruction.

Do not use the power supply circuit
breaker or pull out the plug to turn it off
during operation. This may cause a fire
due to spark, etc.

Keep the power supply circuit breaker and
plug/socket from dirt. Connect the power
supply cord firmly and correctly, lest an
electric shock or a fire potential is created
due to insufficient contact.

Use correct power supply in
accordance with the rating plate
requirement. Otherwise, serious
faults or hazard may occur or a
fire maybe break out.

Do not knit, pull or press the power supply
cord, lest the power supply cord be broken.
An electric shock or fire is probably caused
by a broken power supply cord.

Never insert a stick or similar obstacle
to the unit. Since the fan rotates at high
speed, this may cause an injury.

Do not repair the appliance by yourself.
If this is done incorrectly, it may cause an
electric shock, etc.

Turn off the appliance by remote control
firstly before cutting off power supply if
malfunction occurs.

It is harmful to your health if the cool air
reaches you for a long time. It is advisable
to let the air flow be deflected to all the room.

Prevent the air flow from reaching the gas
burners and stove.

Do not touch the operation buttons
when your hands are wet.

Do not put any objects on the outdoor
unit.

It is the user's responsibility to make the
appliance be grounded according to
