Single Phase Installation
All single phase models require start capacitor, run capacitor and relay in the circuit to start and operate properly. These components can be
purchased separately or prewired in Zoeller Pump Company control panel. For components purchased separately used the diagram for instal-
lation and hookup. Single phase models are nonautomatic. To operate automatically a control panel must be added to the power circuit. Follow
the instructions provided with the panel.
