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.

3.13 Installing the pump in the tank
Pumps with float switches: before installing the
pump, make sure that you have set the length of the
float switch. See “Installing the pump in the tank” on
page 10.
1. Remove the plug from the power cable of the
pump. You may need to cut the cable.
2. Position the pump in the tank.
If the pump has a float switch, make sure it can
move freely.
Unilift CC, KP, APB: Position the pump between
the three positioning dots at the bottom of the
tank so that it stays in place during operation.
See figures 7 and 8.
SEG: The pump weight ensures that the pump
stays in place.
3. Lead the supply cable through the cable gland of
the tank.
4. Tighten the cable gland.

3.14 Inner connecting pipes
3.14.1 Cutting the flexible connecting piece
The inner connecting pipe is delivered with a flexible
connection piece Ø50. You need to cut it to a specific
size, which depends on the pump type. Use the
dimensions in the table below:
3.14.2 Assembling the inner pipes
Use the thread tape delivered with the assembly kit
to seal the threads.
1. Assemble all the parts of the connecting pipe
outside the tank, except for the outlet connecting
piece. See pos. 1 in fig. 9.
2. Fit the connecting pipe to the pump in the tank.
3. Fit the outlet connecting piece to the discharge
port of the tank. Make sure that the pump is in
position and that the float switch, if any, can
move freely, before you tighten the outlet
connecting piece.

3.15 Installing the level sensor tube
If your pump is not equipped with a float switch, you
must install a level sensor tube in the tank.
1. Fix the level sensor tube to the clamps inside the
tank.
The locking ring of the tube must be under the
top clamp to prevent the pipe from rising with the
water level.
2. Lead the level sensor hose through the cable
gland.
3. Tighten the cable gland.
Fig. 13 Correct positioning of the level sensor
tube
3.16 Installing an alarm float switch
If you have an alarm device, you can install an
additional float switch inside the tank and connect it
to the alarm device in order to trigger a high level
alarm.
If you have a controller LC 220 or LC 221, you do not
need an additional alarm float switch as the high
level alarm is triggered by the level sensor.
1. Use a strip to attach the cable of the float switch
to the inner connecting pipe.
Make sure that there is a free cable length of
minimum 70 mm.
Make sure that the float switch can move freely
from its lowest position to its highest position.
2. Tighten strip.
3. Lead the cable through the cable gland.
4. Tighten the cable gland.

3.17 Assembling the discharge pipes
The discharge pipes described in this section are
accessories.
3.17.1 Cutting the pipe (Duolift only)
The discharge pipe kit is delivered with a 2 meter
pipe 50. You need to cut it into 2 pieces of a
specific size, which depends on the Duolift model
and the pump type. Use the dimensions in the table
below:
3.17.2 Assembling
Assemble the discharge pipes according to the
drawing below.
Tip for Duolift:
1. Assemble the whole discharge pipe before
connecting anything to the tank.
2. Connect the assembled discharge pipe to the
tank by tightening the two fitting unions onto the
tank outlets. See pos. 3.

5.1 Product overview
Fig. 19 Unolift 270 / Duolift 270
Fig. 20 Duolift 540
5.2 Applications
The lifting station is designed for pumping grey and
black water from family houses and commercial
buildings where the liquid cannot be led directly to
the sewer due to lack of a natural downward slope.
5.3 Pumped liquids
Unilift CC, Unilift KP, Unilift APB
Grey wastewater: domestic wastewater, excluding
toilet discharge.
SEG pumps
Grey water and black water: domestic wastewater,
including toilet discharge.
The SEG pump has a grinder system.
Surface water must not be discharged into a lifting
station inside the building.
5.4 Automatic operation
The Unolift, Duolift is designed to operate
automatically according to the liquid level inside the
tank.
The system can be set in two ways in order to
operate automatically. It must be either be equipped
with float switches, fitted directly on the pumps, or
with a level sensor tube and a controller.

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. Operating the product
The lifting station is designed to operate
automatically according to the liquid level in the tank.
With a controller, you can easily change settings,
monitor the system or perform troubleshooting.
You can download the installation and operating
instructions for the controller with the following links
and QR codes.
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.
