To connect sanitation facilities (no toilet) to the side inlets,
proceed as follows:
Remove the blind cap which is screwed onto the inlet
connection and remove the black wedge-sealing ring as
well as the white pressure ring from the blind cap.
Plug the union nut (Pos. A), the pressure ring (pos. B) and
the black wedge-sealing ring (pos. C) into the DN 40
drainage pipe and slide it all the way into the container's
inlet opening. Attach the drainage pipe by tightening the
union nut on the inlet connection. The black wedge-seal
must be between the union nut and inlet connection while
you do this. Make sure that the supply lines have a slope
towards the container (see installation examples).
To connect a toilet to the Sekamatik 10 E 7M, proceed as
follows:
The Sekamatik 10 E 7M features a connection in
accordance with DIN1387 / 1388 that is configured with an
inlet height of 180mm.
Set the toilet in front of the plastic box and slide the toilet's
connecting pieces into the facility's mounting clamps. It is
imperative to ensure that the lifting system is not pushed in.
To connect the pressure line, proceed as follows:
To connect the pressure line, use a clamp to attach the DN
25-pressure line at the pipe fitting, located at the top right
side of the container of the lifting system.
Lay the pressure line continuously rising (ideally first
vertically, then horizontally) in a loop above the level of the
backflow level of the public sewer.
This prevents sewage from being pushed back into the
lifting system's container through the pressure line, in the
event of an increase in the water level in the sewer, e.g.
