PRECAUTIONS DURING OPERATION

● 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.

● Do not place plants directly under the air  ow as it is bad for the plants.

● 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.

● 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,
dew 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 generated 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.

● Do not climb on the outdoor unit or put objects on it.

● The product shall be operated under the manufacturer speci 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 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.
