Unit requires 208/230VAC - 2 conductor wires and a ground. No neutral.
•
All indoor units should be wired to the same breaker to prevent some of the units from being powered off while others
are energized.
•
Controller wiring and refrigerant tubing can be arranged and ran together.
•
Disconnect power from both outdoor and indoor units prior to servicing any component in the system
Wire Connections
