unit.
4) Do never install a drier to this R32 unit in order to guarantee its lifetime. The drying material may dissolve and
damage the system.
5) Incompete aring may cause refrigerant gas leakage.
In order to protect the environment, be sure to pump down when
relocating or disposing of the unit.

9.1 Electric wiring
The air conditioner must use special circuit, and wiring by the qualied electrician according to the wiring rules
specied in national standard.
The grounding wire and the neutral wire shall be strictly separated. Connect the neutral wire with grounding wire is
incorrect. The explosion-proof electric leakage breaker must be installed.
All the electric wire must be copper wire.Power supply: 1PH, 220-240V-, 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 qualied person.The connecting cable must be shielded.
Fuse: T3.15A 250VAC(Electronic control unit) T25A 250VAC(Power circuit board).
Please check the circuit diagram about the fuse replaced, explosion-proof fuse.
The specication of power cable is H05RN-F3G 4.0mm
2
.
The specication of cable between indoor unit to outdoor unit is H05RN-F4G 2.5mm2.
9.2 Wiring method
• Wiring method of orbicular terminals
For the connection wire with orbicular terminals, its wiring method is
as shown in the right gure: 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.
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 conrm it is rmly held.
