Three Phase Installation
Three phase pumps are nonautomatic. To operate automatically, a control panel
is required. Follow the instructions provided with the panel to wire the system.
Before installing a pump, check the pump rotation to insure that wiring has been
connected properly to power source, and that the green lead of power cord (See
wiring diagram), is connected to a valid ground, Momentarily energize the pump,
observing the directions of kick back due to starting torque. Rotation is correct
if kick back is in the opposite direction of rotation arrow on the pump casing.
If rotation is not correct, switching of any two power leads other than ground,
should provide the proper rotation.
The above wiring diagram shows a typical hookup for a 230 volt, 3 phase pump,
two variable level float switches, and a magnetic starter. It is not intended that
this diagram cover all applications. See wiring diagram supplied with specific
electrical controllers and panels.
NOTE 1:
Optional sensor cable includes 5 leads; 2 leads for thermal sensor, 2 leads
for moisture sensor, and a green ground lead. If one sensor only is specified, both
sensors are provided and must be hooked up to validate warranty. The sensors
must be specified at time of initial pump order and are not available for field
installation. Sensor wire colors are as shown.

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 control panel. For components purchased separately used the diagram for installation 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.
