The power supply should adopt the rated voltage and special circuit for the ducted
air-conditioning unit.
— About the electric working, please refer to the “circuit diagram” adhering to the unit.
— All the connection of the circuit should be carried out by the qualified electrician.
— A circuit breaker that can cut all the power supply of the system should be installed.
Wiring diagram of the ducted air-conditioning unit is shown in Fig. 32.
