Installation procedure
Electric wiring
Note:
*All the wires should be copper core wires.
*The power cable of indoor unit should be equipped according to the operation manual of indoor unit.
*Before finishing vacuumizing the refrigerant pipe system, do not supply power to outdoor unit.
*The connection of power cable should be complied with local wiring
regulation.
*When connecting the wire of indoor and outdoor unit, check the number on the indoor and outdoor terminal blocks, the same number uses one wire to connect.
*Incorrect wiring easily damage the controller of the air conditioner, or the unit cannot work normally.
Wiring method
1.The wiring method of orbicular terminal | |
For the connection wire which end is orbicular |
|
terminal, its wiring method is as the right figure |
|
shown. Dismantle the screw and put it through |
|
the ring at the end of the connection wire, then |
|
connect it to the terminal block and tighten the |
|
screw. | The wiring method of orbicular terminal |

2.The wiring method of straight terminal
For those connection wires whose end are not orbicular terminals, their wiring method is:
Loosen the connecting screw, insert the end of the wire directly into the terminal block, and then tighten screw. Pull the wire outwards slightly to confirm it is held tightly.
3.Pressing method of connection wire:
After wiring, the connection wire must be pressed with wire holding clamp. The wire holding clamp should press on the out co- ver of the connection wire. As the right fi- gure shown:
Connect wire between indoor & outdoor unit
As the wiring diagram show to arrange the connection wire (note: the two ends of connection wire is different, do not connect them reversedly).
