Work procedure
1.Remove 2 screws to detach the electric component cover.
2.Route each cable through the wiring intake into the electric component box. (Pro-

3.Securely connect the power supply cable and the indoor/outdoor connecting cable
to the terminal blocks.
4.Secure the cables with clamps outside the electric component box.
5.Attach the electric component cover as it was.
• Fix power supply cable and indoor/outdoor connecting cable to electric component
box by using buffer bushing for tensile force. (PG connection or the like.)
Warning:
• Attach the electric component cover securely. If it is attached incorrectly, it
could result in a fire, electric shock due to dust, water, etc.
• Use the specified indoor/outdoor unit connecting cable to connect the in-
door and outdoor units and fix the cable to the terminal block securely so
that no stress is applied to the connecting section of the terminal block. In-
complete connection or fixing of the cable could result in a fire.
