 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 or other
purpose.
• The low-voltage circuit is provided for the remote controller. (Do not connect the high-voltage circuit)
1. Remove the cover of the electrical control box by taking off the mounting screws (2 positions) and
pushing the hooking section. (The cover of the electrical control box remains hanged to the hinge.)
2. Connect the system interconnection wires and remote controller wire to the terminal block of the
electrical control box.
3. Tighten the screws of the terminal block, and fix the wires with cord clamp attached to the electrical
control box.
(Do not apply tension to the connecting section of the terminal block.)
4. Using the attached heat insulation material, seal the pipe connecting port. Otherwise, dewing may be
caused.
5. Mount the cover of the electrical control box without pinching wires.
(Mount the cover after wiring on the ceiling panel.)
