[Wiring procedure]
1) Strip the insulation from the wire (3/4inch (20mm)).
2) Connect the inter-unit wires between the indoor and
outdoor units
so that the terminal numbers match.
Tighten the terminal screws securely. It is recommended
that a slot-head screwdriver be used to tighten the
screws.
3) Be sure to match the symbols for wiring and piping.
4) Pull the wire lightly to make sure that it does not
disconnect.
5) Pass the wiring through the cutout on the bottom of the
protection plate and attach the protection plate.
6) After completing the work, reattach the service lid to its
original position.
