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 v
entilate the
●
room to avoid oxygen insuffi ciency.
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 use any aerosol or hair sprays near the indoor unit.
This chemical
●
can adhere on heat exchanger fi n and blocked the evaporation water fl ow to
drain pan. The water will drop on tangential fan and cause water splashing
out from indoor unit.
Please ensure that outdoor mounting frame is always stable, fi 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.
When operating the unit with the door and windows opened, (the room humidity is always above ●
80%) and with the air defl ector facing down or moving automatically for a long period of time, water
will condense on the air defl 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 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.
This appliance is not intended for use by young children or infi rm persons 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. ●
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 specifi cation 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.
Do not place plants directly under the air fl ow as it is bad for the plants.●
