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.

●
The product shall be operated under the manufacturer specification and
not for any other intended use.
●
Do not put water container (like vase) on the indoor unit to avoid water
dripping into the unit. Dripping water will damage the insulator inside the unit
and causes short-circuit.

ADJUSTING THE AIR DEFLECTORS
1
Adjustment of the conditioned air in the upward and
downward directions.
The horizontal air deflector is automatically set to the
proper angle suitable for each operation. The deflector
can be swung up and down continuously and also set to
the desired angle using the “ (AUTO SWING)”
button.
● 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
6 seconds) may be required before the deflector
starts to move.
● Use the horizontal air deflector within the adjusting
range shown in the right figure.
● 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.
2
Adjustment of the conditioned air to the left and right.
Hold the vertical air deflector as shown in the figure and
adjust the conditioned air to the left and right.
CAUTION
● When operating the unit in cooling operation with the air deflector facing down and moving
