2. Inserting the sump
Insert the sump in the excavation with suitable hoisting
gear and align it horizontally and vertically.
3. Connecting the inlet
Insert the gasket into the inlet socket and slide the DN
150 (DN/0D 160) KGU inlet pipe into the socket.
4. Connecting the pressure pipe
Connect the DN 32 PVC or PE pressure pipe 1 1/4" to the
discharge connection with a screw joint or sleeve.
Quick release couplings with female thread:
1 1/4" x ø40, DN32 (Mat.no JP44796)
1 1/4" x ø50, DN40 (Mat.no JP44797)
1 1/4" x ø63, DN50 (Mat.no JP44798)

5. Connection of venting and cable pipe
Cut off and deburr the DN 100 pipe sockets at the cut-
off point. Using a push-on or slip-on socket pipe (to be
provided by the customer), connect up the connecting
pipes, the pipe between house and sump or equivalent
tubing material with a smooth interior surface.
NOTICE! Please lay both pipes to the pump chamber
with a constant gradient (approx. 3%).
6. Filling in the excavated hole
NOTICE! Top soil, clay, other cohesive soils and the ex-
cavated soil are not generally suitable for filling in the
excavated hole.
Please use non-cohesive soil with a grain size of 2 to 32
mm, without sharp and sharp-edged constituents, as
filling material.
Fill in layers of 30 cm at a time and compact the soil to
97% D. .
Pr
NOTICE! The sump and the optional sump extension
must not be weighted on one side only during the filling
and compacting process.
7. Installation of the sump extension
(accessory)
Install the sump extension as described in the instruc-
tions supplied.
After this, continue filling in the excavated hole. If the
upper flanged area cannot be compacted to 97% D
then suitable measures must be taken (such as filling
lean concrete under the flanged area) to prevent the
sump from subsiding.
8. Installation of the cover (accessory)
Please level out any unevenness in the concrete cover
seating using cement mortar. In addition, fill the gap
between the chamber neck and the cover with cement
mortar. This is particularly important to prevent any dis-
placement from occurring.
