●A circuit breaker should be installed depending on the mounting site of

the unit. Without a circuit breaker, the danger of electric shock exists.

●Do not install near location where there is flammable gas. The outdoor

unit may catch fire if flammable gas leaks around it.

●Please ensure smooth flow of water when installing the drain hose.

ENGLISH

PRECAUTIONS DURING OPERATION

●The product shall be operated under the manufacturer specification and

not for any other intended use.

●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.

●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.

●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 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.
