4.4 Connecting the pipes
If no ventilation takes place through the cover, a separate
ventilation pipe must be laid (via the roof).
Fit the sockets:
Check whether the seal is in the socket.
Insert the socket mating part into the pre-drilled opening
from the inside.
Screw the socket hand-tight onto the mating part so that
tightness is guaranteed.
Push the pipe in.
Carry out these steps again for further pipes.

Drill and fit additional pipes (max. DN 70) if necessary
Additional connections (additional inlets, conduit pipes,
ventilation pipes) must be made at least at the height of
the pre-drilled inlets and with a minimum distance of 10
cm between each other.
