PRECAUTIONS DURING OPERATION
●
The product shall be operated under the manufacturer speci cation and
not for any other intended use.
●
Do not attempt to operate the unit with wet hands, this could cause fatal
accident.
●
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.
●
Please ensure that outdoor mounting frame is always stable, rm 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.
●
Do not use any aerosol or hair sprays near the indoor unit. This chemical
can adhere on heat exchanger n and blocked the evaporation water
ow to drain pan. The water will drop on tangential fan and cause water
splashing out from indoor unit.
!
●
Please switch off the unit and turn off the circuit breaker during cleaning,
C
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.
ENGLISH
●
Do not climb on the outdoor unit or put objects on it.
●
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.
●
Do not place plants directly under the air ow as it is bad for the plants.
●
When operating the unit with the door and windows opened, (the room humidity is always above
80%) and with the air de ector facing down or moving automatically for a long period of time,
water will condense on the air de ector 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 capability of the unit (for example: more
people entering the room, using heating equipments and etc.), the preset room temperature
cannot be achieved.
●
This appliance is not intended for use by young children unless they have been adequately
supervised by a responsible person to ensure that they can use the appliance safely.
●
Young children should be supervised to ensure that they do not play with the appliance.

AIR FLOW LOUVERS ADJUSTMENTS
1. Adjusting the left and right air ow directions
Move the vertical air ow louvers as illustrated,
to adjust the air ow to ow towards the left or
right directions.
2. Adjusting the downward air ow direction.
During the “Dehumidifying” or “Cooling” operating
modes, the horizontal air ow louvers are automatically adjusted to suit the air ow angles of
each operating mode. The air ow louvers are
designed to direct air ow in upward and downward directions. Pressing the automatic air ow
control button, these air ow louvers can also be
adjusted to any air ow angle of one’s choice.
Press the AUTOMATIC AIR FLOW DIRECTION
once will activate the horizontal air ow louvers
to direct the air ows upwards and downwards.
Press the control button again, the horizontal air
ow louvers will stop moving and remain xed at
the position at the point when the control button
was pressed
During the “Dehumidifying” or “Cooling” operat-
ing modes, set the horizontal air ow louvers to
move within the range as recommended in the
illustration
Adjusting the air ow louvers will direct air ows
to assist in reducing the room temperature and
to correct any temperature imbalance
During the “Cooling” operating mode, do not
adjust the horizontal air ow louvers to swing
outside the range as indicated by arrows in the
illustration. Do not operate the horizontal air ow
louvers in durations longer than it is necessary.
Condensate may form and drip along the horizontal air ow louvers.
After stopping the operations of the unit by
pressing control button, the horizontal air
ow louvers will move to park at a position that
covers up the air outlet vent.
While the automatic air ow direction mode is in
operation, any physical adjustment to the horizontal air ow louvers will shift the swing range.
However, with no further physical adjustments,
the air ow louvers will readjust automatically to
the original swing range setting. (Should the louvers could not return to the original swing range
setting, stop the operation of the air conditioner
unit, remove the power supply plug and re-plug
it into the power mains socket and restart the air
conditioner unit. This will return the swing range
to its original setting)

operation mode”, together with your wake up
time in the morning. This will enable you to
enjoy a comfortable room temperature. Please
use the timer effectively.
It is possible
to reduce heat
entering the
room through
windows.
Do Not Forget To Clean The Air Filter
Dusty air lter will reduce the air volume and
the cooling ef ciency. To prevent from wasting
electric energy, please clean the lter every
2 weeks.
Please Adjust Suitable Temperature
For Baby And Children
Please pay attention to the room temperature
and air ow direction when operating the unit
for baby, children and old folks who have

FOR USER’S INFORMATION
The Air Conditioner And The Heat Source In The Room
Caution
!
If the amount of heat in the room is above the cooling
capability of the air conditioner (for example: more
people entering the room, using heating equipments
and etc.), the preset room temperature cannot be
achieved.
Not Operating For A Long Time
When the indoor unit is not to be used for a long
period of time, please switch off the power from the
mains. If the power from mains remains “ON”, the
indoor unit still consumes about 8W in the operation
control circuit even if it is in “OFF” mode.
When Lightning Occurs
Warning
!
To protect the whole unit during lightning, please
stop operating the unit and remove the plug from
the socket.
ENGLISH
Interference From Electrical Products
