Test run

If the pump is installed stationary (e.g. cesspool, overflow shaft), carry out a test run. Check the following points with the test run:

  • General conditions (inflow quantity, switching points)
  • Direction of rotation (with 3~ motors)

The test run must include three pump cycles.

  1. Flood the pump chamber: Open inlet.
    NOTICE! The required feed quantity for the test run can also be simulated using another water source.
  2. When the switch-on level is reached: pump starts.
  3. Switch-off level reached: pump stops.
  4. Repeat two more pumping processes.
  1. Once three pumping processes have been completed without problems, the test run is finished.

NOTICE! If the pump does not switch on once a week, repeat the test run every month.
