CAUTION:
Use special power supply for the air conditioner. Design power supplies specific to the indoor unit and outdoor
unit. The supply voltage must comply with the nominal voltage.
The external supply circuit of the air conditioner must have a ground wire, and the power supply ground wire of
the indoor unit must be connected with the external ground wire firmly.
The wiring must be performed by professional technicians according to the circuit diagram labels.
Distribute the wires according to the relevant electric technical standards promulgated by the State, and set
the Residual Current-operated Circuit Breaker (RCCB) properly.
The power wire and the signal wire shall be laid out neatly and properly, without mutual interference or
contacting the connection pipe or valve.
No power cable is attached to this equipment. The user can select the power cable by reference to the
stipulated power supply specifications. No joint of wires is allowed.
Upon completion of wire connection, double check it and then connect the power supply.
