and Radio wiring and the power to the indoor unit.
14 Gauge AWG stranded wire should be used to make the
electrical connection between indoor and outdoor units.
This wiring will serve to power the indoor unit and establish a
communication link between indoor and outdoor units.
The wiring is connected at the indoor unit electrical terminal
blocks screws 1, 2, 3 and ground. There should be no
splices in the wires connected to terminals 1 or 3 as these
serve as communication signal wires and electrical power
power to the indoor unit, break wire 2 only.
