l Inlet pipe
The inlet pipe must be laid at a gradient to the KESSEL lif-
ting station in accordance with EN 12056 and be routed as
straight as possible. Connection is with DN 150
l Ventilation
The ventilation pipe sets up pressure compensation to the
fresh air for the air flowing into or out of the system during
emptying or filling. Connection is designed with DN 100 (DA
110 mm) and must be routed to above the roof to avoid
odour pollution.
l Pressure line
The pressure line used to drain the dirty water into the sewer
system must be connected directly to the respective pres-
sure line connection. In compliance with the specifications
of EN 12056, the pressure line must be laid above the local
back-up level and should be connected to a vented mains
pipe or distributing main.
For acoustic decoupling purposes and to avoid the transfer
of forces, the supplied rubber braided hose of approx. 4 m
in length always needs to be pushed over the pressure pipes
at the pressure connection and fixed via a hose clip. The
rubber braided hose connection is not a longitudinal force-
fit connection. This must be attached on site e.g. using hol-
ders.
The pressure line must be fitted (see below) so that the no
forces are exerted on to the system and that there is no di-
rect contact with the building (structure-borne noise). No
other drainage objects may be attached to the pressure line.
The tightness and strength must be guaranteed even under
pressure.
This should be tested when the system is commissioned.
To avoid pressure shocks, the pressure line should not be
connected too tightly to the building. If cast iron or steel
pressure pipes with low damping properties are used, a
pressure shock damper must be fitted into the pressure line
if the pumping height exceeds 5 m.
A gate valve needs to be installed in the pressure line on site
as stipulated in EN 12056. We recommend using the
blocking devices for Mono-systems (Art.No. 28683) and for
Duo-systems (Art.No. 28694) from the KESSEL accessories
range.
Check valves to prevent pressure shocks for installation in
the pressure line are available as accessories:
DN 80 check valve from GG (Art. No.: 206-199
DN 100 check valve from GG (Art.No .206-198)
Backflow preventer (Art.No. 206-200)
4. Installation and assembly
4.3. Recording the level
Setting the float switch
The float switches are fitted and set in the factory. Changing
the settings can lead to malfunctions.
Four float switches are required to switch this system (OFF
- ON1 - ON2 - ALARM). The alarm level lies approximately
at the same height as the lower edge of the supply pipe.
If another switching level is required, the floats need to be
set accordingly. However ensure that the alarm float does
not switch above the supply pipe and that the OFF float pre-
vents air from being sucked in. Complete flooding of the
pump is advisable.
