Connecting The Pipes - Kessel Aqualift S LW 1000 Installation, Operation And Maintenance Instructions

4.1.3 Approximation to the ground level
When you are setting the telescopic attachment piece to gro-
und level, observe the following
• If the surface is to be finished with paving stones, the
• Installation in paved area
attachment piece must be levelled to 2 cm higher than the
finished surface. When the vibratory plate compactor is
used on the paving stones, also compact on the perimeter
of the upper section around the manhole cover. Care must
be taken that the cover plate is in place (see the illustration
on the left near the section "Installation of base").
• The telescopic attachment piece must be encased in a

reinforced concrete plate approx. 18 cm thick made of con-

4.2 Connecting the pipes

Inlet pipe (connection muff
DN 100/150)
(connection muff OD 40 mm) must be
Pressure pipe
routed above the backwater level in
accordance with DIN EN 12056
All pipes must be routed so that they can run empty auto-
matically. All pipe connections must be flexible and sound in-
sulated where routed within buildings (DIN 4109). The pipe
connections DN 100/150 for the inlet pipe, the ventilation
pipe and the cable conduit can be made using simple KG
pipe DN 100 or DN 150.
The inlet pipe must be laid at a gradient (1-2 %) to the KES-
SEL chamber system in accordance with EN 12056 and be
routed as straight as possible. Bends or similar must be avoi-
ded. Connection to the inlet of the chamber system can be
with a double muff.
All the necessary electric cables must be routed from and to
the pumping station through the cable conduit (DN 100). The
conduit must not be used for any other purpose. Only 30° - 45°

crete, about 2.3 x 2.3 m in size (see the illustration on the
right near the section "Installation of base").
The exact design of the concrete plate must be calculated
according to the given local circumstances. A standard
formwork plan and reinforcement drawing can be provided
by KESSEL.
• In order to adapt installation to the existing ground level it

can be necessary to saw the attachment piece to size.
Make the cut as straight as possible and then deburr or
chamfer it.
The lift-out key provided and the operating manual must be
stored on hand and dry e.g. near the electrical control unit.
Please note:
All connection pipes must be routed with
gradient to the chamber.
bends should be used for the cable conduit so that the requi-
red cables can be inserted easily after the conduit has been
laid (e.g. using pulling wire).
The cable conduit must be sealed air and water-tight after the
electrical connection work has been completed (e.g. by means
of polymer foam or socket plugs with PG screw connection).
This avoids odour pollution in the building and prevents water
leaking into the cellar in extreme situations.
The ventilation pipe (DN 100) provides pressure com-
pensation for the air flowing into or out of the system during
emptying or filling. Since the KESSEL chamber system is
usually installed near the respective building, the ventilation
pipe must be routed – as straight as possible – to above the
roof to avoid odour pollution.
