•When installing the built-in type air conditioner, keep all electric cables such as the power cable and

the connection cord in

•pipes, ducts, or cable channels to protect them from the danger of impact or any other incidents.

1-2 Power supply and circuit breaker

•If the power cord of the air conditioner is damaged, it must be replaced by the manufacturer or a

qualified person in order to avoid a hazard.

•The air conditioner must be plugged into an independent circuit if applicable or connect the power

cable to the auxiliary circuit breaker. An all pole disconnection form the power supply must be

incorporated in the fixed wiring with a contact opening of>3mm.

•Do not extend an electric cord to the air conditioner.

technology, the Single User Mode will further minimize your energy consumption and reduce your

electricity bill by adjusting the maximum operating capacity of the compressor.

•Easy Filter

be cleaned easily and more frequently. Constant filter cleaning will prevent dust from entering the

product or accumulating on the filter.

•good'sleep function

good’sleep function will allow you to have deep, good night’sleep by adjusting the temperature, fan

speed and air flow direction.

•Smart Install
