Wiring
[Wiring procedure]
1) Strip the insulation from the wire (3/4 inch (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) After completing the work, reattach the shield cover and
right side plate to their original positions.
• Attach so that the shield cover hooks (2 locations) are
securely engaged.
Shape the wires so that there is
no lifting of the shield cover or
other structural parts.
Use the specified wires and
connect them securely.
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.
