Prior to operation
8Indoor Unit
Prior to Operation
1. Contact an installation specialist for installation.
2. Use a dedicated circuit.
1. Being exposed to direct airflow for an extended period of time could be hazardous to your health.
Do not expose occupants, pets, or plants to direct airflow for extended periods of time.
2. Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or
other heating devices.
3. Do not use this air conditioner for non-specified special purposes (e.g. preserving precision
devices, food, pets, plants, and art objects). Such usage could damage the items.
1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling
sharp metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation,
leading to possible electric shock.
3. When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates
at a very high speed during operation. There is a possibility of injury if the unit’s power is
accidentally triggered on while cleaning inner parts of the unit.
For repair and maintenance, contact your authorized service dealer.

the air conditioner
cools the warm room
air.
• This is the protector
of the mechanism.
• Wait about three
minutes and
operation will begin.
The air conditioner
does not operate. The room has a peculiar odor. It seems that condensation is
leaking from the air
conditioner.
Air conditioner does

air inlet or outlet vents
obstructed?
• For a noise that
sounds like water
flowing.
-This is the sound of
freon flowing inside

sounds like the
compressed air
releasing into
atmosphere.
-This is the sound of
the dehumidifying
water being
processed inside the
air conditioning unit.
• This sound is generated
by the expansion/
constriction of the front
panel, etc. due to
changes of
temperature.
• Cleaning the filter,
press the Timer button
and button of wired
remote controller at
the same time for 3
sec.
• Are the batteries
