Cable connection

REQUIREMENT

Be sure to connect the cables matching the terminal numbers. Incorrect connection causes a trouble.

Be sure to pass the cables through the bushing of cabling connection port of the indoor unit.

Keep a margin (Approx. 100mm) on a cable 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)

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 cables and REMOCON cable 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 cables 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 cables. (Mount the cover after cabling on the ceiling panel.)
