ELECTRICAL WIRING
WARNING
• Follow local codes when selecting wire gauge and connecting to building power.
• Use the cable strain relief clips and locking conduit clamps to prevent wires from being pulled off terminal posts.
• Unit must be properly grounded. Do not use water or gas piping, phone ground or lightning rod.
• Use only a properly sized circuit breaker. Use only properly sized copper conductors or electric shock could occur.
• 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.
