The power supply cables can be inserted into the pipe
holes. Enlarge the pipe holes if they are too small.
Be sure to fix the power cable and indoor/outdoor
connecting cable with bundling band sold on the market
so that they do not make contact with the compressor and
the hot pipes.
To ensure good tensile strength, the electric cables must be
fastened using the cable-holder on the plate (See fig. 10).
