NOTES:
1.
Unit wire sizing amps are equal to 125% of the largest compressor-motor RLA plus 100% of the other compressor RLA's.
2.
Multiple point power supply requires a separate fused disconnect for each circuit to supply electrical power to the unit.
3.
External compressor overload option is only available for units with 140
°
F maximum leaving condenser water temperature.
4.
Wire sizes shown above are for standard ambient temperature and short runs of wire.
