Wire connection
REQUIREMENT
• Be sure to connect the wires matching the terminal numbers. Incorrect connection causes a trouble.
• Be sure to pass the cables 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.
• Remove the cover of the electric parts box by taking off the mounting screws (3 positions) and pushing the
hooking section. (The cover of the electric parts box remains hanged to the hinge.)
• Connect the indoor/outdoor connection wires to the terminal block of the electric parts box.
(Do not apply tension to the connecting section of the terminal block.)
• 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.)
• Using the attached thermal insulation material, seal the pipe connecting port. Otherwise, dewing may be caused.
• Mount the cover of the electric parts box without pinching wires.
(Mount the cover after cabling on the ceiling panel.)
