Installation procedure
Electric wiring
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).
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:
