Now set the manual/0/automatic switch to "Automatic" and do a trial run. To do this, the collection
chamber is filled through the normal inflow (washbasin, toilet, etc.). The system has to switch on
automatically, pump the chamber empty and switch on again. After switch-off, no water may run back
into the chamber from the pressure main.
Correct the follow-up time according to installation conditions and conveying height so that the pump
evacuates the collection chamber to a maximum and only runs dry for a short time (loud noise when
pumping). The back-flow pipe may no longer be immersed into the liquid after the pumping process is
finished. The follow-up time can be changed by means of the digital potentiometer on the switch device.
During the trial run, recheck all connections and fittings for leakage and re-seal where necessary.
If the lifting unit is running properly, the switch remains in the "Automatic" setting.
7. MAINTENANCE / REPAIRS
