- You need the controller, the 4 float sensors, the console screws and a flat-head screwdriver.
- Cable: 2 runs of 4-core cable, one for the tank sensors and one for the sump sensors.
- Only a water tank and no sump? Contact support for the right wiring before you install.

Connect the power and the motor
Connect the single-phase supply phase to P and neutral to N. Connect the motor between L and neutral.
Connect it in parallel with your motor switch or starter, so you can still run the motor by hand.
