Wiring
<Wiring procedure>
1) Strip the insulation from the wire (3/4inch (20mm)).
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.
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.
Shape the wires so that there is
no lifting of the service hatch or
other structural parts.
CAUTION
• Precautions to be taken for power supply wiring. When using stranded
wires, make sure to use the round crimp-style terminal for connection to
the power supply terminal block.
