PRECAUTIONS DURING OPERATION
●Do not attempt to operate the unit with wet hands, this could cause fatal
accident.
●When operating the unit with burning equipments, regularly ventilate the
room to avoid oxygen insufficiency.
●Do not direct the cool air coming out from the air-conditioner panel to face
household heating apparatus as this may affect the working of apparatus
such as the electric kettle, oven etc.
●Do not place plants directly under the air flow as it is bad for the plants.
●Please ensure that outdoor mounting frame is always stable, firm and
without defect. If not, the outdoor unit may collapse and cause danger.
●Do not splash or direct water to the body of the unit when cleaning it as this
may cause short circuit.
●When operating the unit with the door and windows opened, (the room humidity is always above
80%) and with the air deflector facing down or moving automatically for a long period of time,
water will condense on the air deflector and drips down occasionally. This will wet your furniture.
Therefore, do not operate under such condition for a long time.
●If the amount of heat in the room is above the cooling or heating capability of the unit (for
example: more people entering the room, using heating equipments and etc.), the preset room
temperature cannot be achieved.
●Do not climb on the outdoor unit or put objects on it.
●Please switch off the unit and turn off the circuit breaker during cleaning, the
high-speed fan inside the unit may cause danger.
●Turn off the circuit breaker if the unit is not to be operated for a long period.

Adjustment of the conditioned air in the upward and
downward directions.
According to “Dehumidifying” or “Cooling” operation,
the horizontal air deflector is automatically set to
the proper angle suitable for each operation. The
deflector can be swung up and down and also set
to the desired angle using the “ (AUTO SWING)”
button. (If the angle of the deflector is changed, it
will not return to the auto-set position after operations
start unless the operation mode is switched.)
ADJUSTING THE AIR DEFLECTORS
●If the “ (AUTO SWING)” button is pressed
once, the horizontal air deflector swings up and
down. If the button is pressed again, the
deflector stops in its current position. Several
seconds (about 12 seconds) may be required
before the deflector starts to move.
●Swinging the air deflector is effective to reduce
unevenness of the temperature in the room.
●In “Cooling” operation, do not keep the
horizontal air deflector swinging for a long time.
Some dew may form on the horizontal air
deflector and some dew may drop from it.
●When the “ (AUTO SWING)” button is pressed
while the operation is stopped, the horizontal air
deflector moves and stops at the position where
the air outlet closes.
●When the auto swing operation is performed, if
the horizontal air deflector is moved manually,
the swinging range may drift. However, it will
return to the original operation range after a
short time.
