Notes:
1. Use 18 Gauge, 4 conductor, interconnect cable between the
AirStar unit and Remote Switch Panel.
When any 24V circuit exceeds 150 feet, use #16 AWG.
2. As shown, 3 conductors of the 24V circuit cable from each compressor
connect via the user-supplied interconnect cable.
3. The fourth conductor of interconnect cable to be used for future
equipment options/enhancements.
4. Leave with factory connection, without a 24 V Switch, or connect
the associated interconnect cable directly to remote switch.
Please note that one switch is used for each compressor.
