• A metal pipe can be installed through the hole for
wiring. If the hole size does not fit the wiring pipe to
be used, drill the hole again to an appropriate size.
• Be sure to clamp the power wires and system
interconnection wires with a banding band along the
connecting pipe so that the wires do not touch the
compressor or discharge pipe.
