perform curling.
Problems with the work may cause heat and fires.

In case using stranded wires is unavoidable for
some reason, make sure to install the round crimp-

<Wiring procedure>
1) Strip the insulation from the wire (3/4”).
2) Connect the connection wires between the indoor and
outdoor units so that the terminal numbers match.
Tighten the terminal screws securely. We recommend
a flathead screwdriver be used to tighten the screws.
The screws are packed with the terminal board.
3) Be sure to match the symbols for wiring and piping.
4) Pull the wire and make sure that it does not
disconnect. Then fix the wire in place with the binding
band.
