4. Installing the lifting station
4.1 Location
Install the product in a location that meets the
following requirements:
•
Make sure that the location is properly lit.
•
Make sure that the location is properly vented.
•
Make sure that there is at least 60 cm free space
around the product.
•
We recommend that you install a drainage pump
in a pump sump below floor level if you install the
lifting station in a basement with the risk of
penetrating groundwater. In some countries, a
drainage pump or only a pump sump is required.
The lifting station may be flooded
maximum 2 metres for seven days.

The isolating valves can be made of cast iron or
PVC. The end of the PVC valve can be pushed
directly into the socket with a plug-in seal.
2. Connect the pump to the isolating valve.
3. Fasten the pump to the floor using the dowels and
screws supplied with the lifting station.
4. Fit the vent flange to the pump outlet flange.
5. Drill a hole in the tank connection for the vent
hose.
6. Connect the vent hose to the vent flange and to
the tank.
7. Fit a non-return valve to the vent flange. Lifting
stations must be provided with an approved non-
return valve according to EN 12050-4.
