3. Installing the product
3.1 General guidelines
The guidelines for correct mechanical installation of
lifting station are according to EN 12056-4.
• If the lifting station is installed in a basement with
recurrent penetration of groundwater, we
recommend that you install a drainage pump in a
separate pump sump below floor level. In some
countries the drainage pump is mandatory. If there
is only a risk of penetrating groundwater, we
recommend that you install a float switch outside
the lifting station and connect it to a controller
which indicates high-level alarm in case of
flooding.
• Fix the tank to the floor.
• We recommend that you connect a diaphragm
pump to the tank to be able to empty the tank
manually.
• All outlet pipes from the lifting station, diaphragm
pump and drainage pump must have a backflow
loop, i.e. a bend above the local backflow level.
Commonly, the highest point of the bend must be
above street level. See fig. 2 Installation example
with a tank on the basement floor. The diaphragm
pump is not shown.
• Surface water must not be discharged into the
lifting station inside the building. Collect and
discharge surface water outside the building.
• Install a non-return valve at the outlet of the lifting
station to prevent backflow.
• Fit 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 backflow loop must be
smaller than the effective tank volume. See pos. 7
in fig. 1 Installation example with a tank in a sump
and with a controller. The diaphragm pump is not
shown. and fig. 2 Installation example with a tank
on the basement floor. The diaphragm pump is
not shown.
• In general, a lifting station for black wastewater
must be vented above roof level. However, it is
permitted to lead the vent pipe into the main
building ventilation system. Place special two-way
venting valves 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.
• Use 45° bends to avoid deposits in the pipes.

3.2 Mechanical installation
3.2.1 Tank inlets
We recommend that you connect the inlet pipes to the
top inlets of the tank. This prevents backflow and
deposits in the inlet pipe, and enables a high start
level of the pump. A high start level increases the
effective tank volume and reduces the number of
start/stops of the pumps.
3.2.2 Location
Install the lifting station 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
light can affect the properties of its composite
material, resulting in a shorter life.
The product is designed for indoor operation. If
installed outside, the lifting station must be placed in
a closed pit.
The tank can be flooded and may be installed in a
basement with risk of penetrating groundwater.

3.7 Drilling holes for the pipes
CAUTION
Sharp element
Minor or moderate personal injury
‐Wear protective gloves.
The tank has three or four holes, ∅100, for the inlet
pipes, depending on the size. The tank also has a
hole, ∅40, for the diaphragm pump. See section
Product overview. These holes must be drilled to be
used.
Holes for the outlet pipes, the vent port and the
minimum required cable glands are open.
1. Determine which inlets you want to use. See
sections Tank inlets and Setting the start levels.
2. Drill holes with a hole saw. The diameter of the
hole saw must be the same as the diameter of the
pipe.
Inlet: ∅100
Hole for diaphragm pump: ∅40
3. Deburr the holes.

3.12 Installing the pump
Pumps with float switches
Adjust the cable length of the float switch before you
install the pump. See section Setting the start levels
with float switches.
1. Remove the plug from the pump cable. You may
need to cut the cable.
2. SEG: Fit the foot extensions. See fig. Fitting the
foot extensions on the SEG pump.
3. Position the pump in the tank. Make sure that the
float switch, if any, 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 Correct position of UNILIFT
CC and KP pumps and Correct position of
UNILIFT APB pumps. SEG: The pump weight
ensures that the pump stays in place.
