1. Electric wiring
The air conditioner must use special circuit , and wiring by the qualified electrician according to the wiring rules specified in national
standard.
The grounding wire and the neutral wire shall be strictly separated. Connect the neutral wire with grounding wire is incorrect.
The electric leakage breaker must be installed.
All the electric wire must be copper wire.Power supply: 1PH, 220-230V~, 50/60Hz.
The wiring method of power line is Y connection. If the power line is damaged, in order to avoid risk of electric shock, it must be replaced
by the manufacturer or its repair center or other similar qualified person.The connecting cable must be shielded.
Fuse: T3.15A 250VAC T16A 250VAC (Please check with the outdoor unit wiring diagram.)
Please check the circuit diagram about the fuse replaced.
Wiring method of orbicular terminals
For the connection wire with orbicular terminals, its wiring method is as shown in
the right figure: remove the connecting screw, put the screw through the ring on
the end of the wire, then connect to the terminal block and fasten screw.
Wiring method of straight terminals
.
Crimp connection method for wires without terminals
For the connection wire without orbicular terminals, its wiring method is: loosen
the connection screw, and insert the end of the connection wire completely into
the Terminal block, then fasten the screw.
Slightly pull the wire outwards to confirm it is firmly held.
Note: Power line and communication wire are provided by consumers themselves.

In order to protect the environment, be sure to pump down when relocating or disposing of the unit.
1) Remove the valve caps from liquid stop valve and gas stop valve.
2) Carry out forced cooling operation.
3) After five to ten minutes, close the liquid stop valve with a hexagonal wrench.
4) After two to three minutes, close the gas stop vaile and stop forced cooling
operation.
Crimp connection method for connection wire
After connection,the wire must be fastened by wire cover. The wire cover shall press on the protection
coat of the connection wire,as shown in right top figure.
Note:When connecting the wiring,confirm the terminal number of indoor and outdoor units carefully.
Incorrect wiring will damage the controller of air conditioner or the unit can not operate.
3. Wiring method of outdoor unit:
Power line
Remove the repair board of the outdoor unit and loosen the wire cover A,then put the live wire, neutral wire and grounding wire through
the wire cover ,and connect them to terminal block correspon dingly. After connection, fasten wire cover to its previous state.
Communication wire of indoor unit.
Loosen wire cover , put the communication wire through the wire cover B, and connect them to terminal block correspondingly. After
connection, fasten wire cover B to its previous state.
