Wire connection

REQUIREMENT
Connect the wires matching the terminal numbers. Incorrect connection causes a trouble.
Pass the wires through the bushing of wire connection holes of the indoor unit.
Keep a margin (Approx. 3.9" (100 mm)) on a wire to hang down the electrical control box at servicing.
The low-voltage circuit is provided for the remote controller. (Do not connect the high-voltage circuit)
1
Loosen the cover mounting screws (2 positions) of the electrical control box, and then remove the
cover.
2
Connect the indoor power supply wire, system interconnection wires and the remote controller wire to
the terminal block of the electrical control box.
3
Tighten screws of the terminal block securely, and fi x the wires with code clamp attached to the
electrical control box. (Do not apply tension to the connecting section of the terminal block.)
4
Mount the cover of the electrical control box so that it does not pinch the wires.
