**Main power wire from electrical panel to outdoor unit.
Notes:
1) System must be on a single dedicated circuit.
2) Main power is supplied to the outdoor unit.
3) Use table above to size over current protection.
4) Follow all local building codes and NEC (National Electrical Code) regulations.
Interconnecting Cable: Recommended cable - 14/4 AWG stranded bare copper conductors THHN 600V unshielded wire
Note: Use shield cable if installation is in close proximity of RF and EMI transmitting devices.
Condensate Drain Size: 5/8-in OD 7/16-in ID
Note: Insulate condensate drain hose to prevent sweating and possible water damage.
