3. Installing the product

3.1 General guidelines

Guidelines for correct mechanical installation of

lifting station are according to EN 12056-4.

• If the lifting station is installed in a basement with

regular penetrating groundwater, we recommend

to install a drainage pump in a separate pump

sump below floor level (mandatory in certain

countries). If there is only a risk of penetrating

groundwater, we recommend to install a float

switch outside the lifting station and to connect it

a controller, which will indicate an high level

alarm in case of flooding.

• The collecting tank must be fixed to the floor.

• We recommend that you connect a diaphragm

pump to the collecting tank in order to be able to

empty the tank manually.

• All outlet pipes from the lifting station, diaphragm

pump and drainage pump must have a backwater

loop, i.e. a bend above the local backwater level.

Commonly, the highest point of the bend must be

above street level. See fig. 2.

• Surface water must not be discharged into the

lifting station inside the building. It must be

collected and discharged outside the building.

• A non-return valve must be installed at the

discharge of the lifting station to prevent back

flow from the sewer for example.

• Install isolating valves at the inlet and outlet of

the lifting station.

• The volume of the outlet pipe above the non-

return valve up to the backwater loop (bend in the

pipe) must be smaller than the effective tank

volume.

• In general, a lifting station for black wastewater

must be vented above roof level. However, it is

permitted to lead the ventilation into the main

building ventilation system. Special two-way

venting valves must be placed outside the

building.

• If the wastewater is discharged into a collecting

line, the collecting line must have a filling ratio of

at least h/d = 0.7. The collecting line must be at

least one nominal diameter bigger after the outlet

pipe connection.

• 45 degrees bends must be used to avoid

sedimentation in pipework.

3.2 Choice of tank inlets

It is optimal to lead your pipework to the top inlets of

the tank, as it will prevent backflow and

sedimentation in the inlet pipe and give you the

possibility to use a high start level for the pump. A

high start level increases the effective tank volume

and decreases the numbers of start/stop of the

pumps.

If you use the bottom inlet, you have to select the

lowest start level. If the start level is above the inlet

height, there will be backflow in the inlet pipe. thus

increasing the risk of sedimentation in the pipework.

3.3 Location

The lifting station must be installed in a properly lit

and vented room with 60 cm free space around all

parts to be serviced and operated.

The tank must not be exposed to direct sunlight. UV

can affect the properties of its composite material,

resulting in a shorter life.

The product is designed for indoor operation. If

installed outside, it must be placed in a closed pit.

The tank can be flooded and may be installed in a

basement with risk of penetrating groundwater.

5.6 Diaphragm pump

We recommend to connect a diaphragm pump to the

tank. It is a positive displacement pump which can

be operated manually. It can be used to drain the

tank before service or during power cuts. The tank

has a pre-built inlet DN 40 especially designed for it.

5.7 Level sensor tube

The level sensor is an accessory, which works

together with a controller LC 220 or LC 221.

The level sensor tube is connected to a

piezoresistive level sensor in the controller via its

pressure hose.

The rising liquid level compresses the air inside the

pressure tube and pressure hose, and the

piezoresistive sensor transforms the changing

pressure into an analogue signal. The controller

uses the analogue signal to start and stop the pump

and to indicate high water level alarm.

6.1 Setting the start levels

The start level is closely related to the chosen inlets.

Choose a start level which will ensure a minimum

backflow in the inlet pipe, thus avoid risk of blockage

by sedimentation in the inlet pipe.

Set the start level as high as you can according to

your setup.

A high start level increase the tank effective volume

and decrease the numbers of start/stop of the

pumps.

The following illustrations show the allowed start

levels according to the inlet. Theses specific values

can only be selected with the LC 221 controller.
