Once the pipe work is complete, the electrical supply can be
connected by routing the cable through the appropriate casing
holes or knockouts and connecting the supply and ground
cables to the unit’s power terminal.
Be sure the power wiring and control wiring do not cross as
this might cause disturbance on the controls side. See Fig. 14
for wiring diagram.
NOTE:
The indoor unit requires its own power supply. Indoor
units are not powered through outdoor units.
