7.1. Indoor unit (Fig. 7-1) (Fig. 7-2) (Fig. 7-3)
Work procedure
1. Loosen the two screws securing the electric component cover, and then slide and
remove the cover.
2. Route the wires along the wiring routes and through the wire inlets in the electric
component box.
(Procure the power supply cord and indoor/outdoor unit connecting cable locally.)
3. Securely connect the power supply cord and the indoor/outdoor unit connecting
cable to the terminal block.
4. Secure the wires with the cable straps inside the electric component box.
Secure the wires with cable straps as cushioning components so that no stress is
applied to the connecting sections of the terminal block when tension is generated.
5. Install the electric component cover.
Make sure that the wires do not get pinched.
• Do not allow slackening of the terminal screws.
• Tape is affi xed over the conduit hole used for connecting the electric wiring.
Please remove this tape if making a connection through the hole.
Warning:
• Insert hook the electric component cover into the bent support on the electric
component box and attach the cover securely. If it is attached incorrectly, it
could result in a fi re, electric shock due to dust, water, etc.
• Use the specifi ed indoor/outdoor unit connecting cable to connect the indoor
and outdoor units and fi x the cable to the terminal block securely so that no
stress is applied to the connecting section of the terminal block. Incomplete
connection or fi xing of the cable could result in a fi re.
