CAUTION
Pumps can start up unexpectedly.
Before undertaking maintenance or repair work on the system, switch it off or disconnect it from the power supply.
The pump must never run dry or in slurping operation; the multi-vane impeller and pump housing must always be
flooded up to at least the minimum immersion depth.
The pump may not be used if the pressure pipe is not connected.
The pump builds up a pumping pressure/excess pressure.
Operating and maintenance instructions must be kept available at the product.
NOTICE
Improper cleaning
Plastic components can become damaged or brittle
Only clean plastic components with water and a pH-neutral cleaning agent.
2.2

Intended use
The backwater lifting station has been designed for pumping faecal and faecal-free wastewater. The assemblies for the
pumps, the level measurement and the motor-driven backwater flap are installed in the drain body.
In normal operation, the wastewater passes through the backwater lifting station to the wastewater sewer without backflow.
If the wastewater from the sewer system backs up into the backwater lifting station, this is detected by an optical probe
(backwater flap). The motor-driven backwater flap closes. The wastewater from the building then collects in the drain body of
the backwater lifting station.
The switching signals of the level measurement in the tank are processed electronically in the control unit. An optical probe
(pump) is used for level detection. Once the relevant level has been reached, pumping away via the drain body of the back-
water lifting station is activated, against the backwater.
In the event of a power outage, the functional reliability of the motor-driven backwater flap can be ensured for a period of
approx. 2 hours by means of battery mode. After this period, the backwater flap is closed to protect the building.
