3.10

Ensure ventilation

With exposed installation, make sure that the pre-assembled
ventilation valve incl. activated carbon filter <11> is screwed tightly.
For use within a chamber, dismantle the ventilation valve and route
the venting pipe via the backwater level, see the section below.

3.10.1 Connecting the venting pipe

In order to ensure the function of the system in chamber installation
in case of flooding, the venting pipe is to be laid at least 10 cm above
backwater level.
The venting pipe must be routed in such a way that it
does not hinder access for maintenance purposes nor the other
pipe connections (pressure pipe / cable conduit pipe).
- Screw the venting valve <11> out of the pump unit
<20> (see Fig. [17]).
- Fix the venting pipe to the connection <12> on the venting valve (1/2 inch).
Make sure the seal between the ventilation pipe and the drain
body fits properly.
