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 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.
