• For communication / connection (power) wires between the Single
Zone outdoor unit and the indoor unit for lengths up to 130 feet,
use a minimum 18 gauge, four (4) conductor, stranded, shielded
or unshielded wire. If shielded, the wire must be grounded to the
chassis at the outdoor unit only.
• When the communication / connection (power) wires between the
indoor unit and outdoor unit is GREATER THAN 130 feet, use:
• A two (2) conductor wire for power.
• A two (2) conductor wire for communication / ground.
• Separate the power AT LEAST two (2) inches away from the
communication / ground wire.
• All wiring is still minimum 18 gauge, stranded, shielded, or
unshielded as cited above.
• Insulation material as required by local code.
• Firmly attach the cable; provide slack but secure in a way to pre-
vent external forces from being imparted on the terminal block.
• Wiring must be completed without splices.
• Always verify the communication cable is connected to a communications terminal on the Single Zone Extended Piping unit. Never apply
line voltage power to the communication cable connection. If contact is made, the PCBs will be damaged.
• The shield of the communications cable connecting the outdoor unit to the indoor unit must be grounded only to the outdoor unit frame.
• Tie the shield of each cable segment together using a wire nut at the indoor unit. Maintain polarity throughout the communication network.
• Position the incoming power to the outdoor unit away from the power / communications cables from the outdoor unit to the indoor unit.
• Never use a common multiple-core communications cable.
All power wiring and communication cable installation must be per-
formed by trained service providers working in accordance with local,
state, and National Electrical Code (NEC) / UL / ETL federal regulations
related to electrical equipment and wiring, and following the manufac-
turer product diagrams, requirements, and instructions in this manual.
Failure to do so will lead to electric shock which can cause physical
injury or death.
