REQUIREMENT
• Be sure to connect the wires matching the terminal numbers. Incorrect connection causes a trouble.
• Be sure to pass the wires through the bushing of wiring connection port of the indoor unit.
• Keep a margin (Approx. 100mm) on a wire to hang down the electric parts box at servicing, etc.
• The low-voltage circuit is provided for the remote controller. (Do not connect the high-voltage circuit)
• Make a loop on the wire for margin of the length so that the electric parts box can be taken out during
servicing.
1. Remove the cover of the electric parts box by taking off the mounting screws (2 positions) and pushing
the hooking section. (The cover of the electric parts box remains hanged to the hinge.)
2. Connect the power supply wire and remote controller wire to the terminal block of the electric parts box.
3. Tighten the screws of the terminal block, and fix the wires with cord clamp attached to the electric parts
box. (Do not apply tension to the connecting section of the terminal block.)
4. Using the attached thermal insulation material, seal the pipe connecting port. Otherwise, dewing may
be caused.
5. Mount the cover of the electric parts box without pinching wires.
(Mount the cover after wiring on the ceiling panel.)
