installed in the wall.
The ventilation pipe is not required.
n

If an external siphon is connected, the device requires additional ventilation of
the drain section via a vent pipe which is attached to the drain pipe and prevents
the device from overflowing. This vent pipe is provided with holes (1) in the
lower area to achieve a suction effect.
The ventilation pipe must be fitted with a funnel (item number: 60.76.798) (2).
The funnel destroys any occurring foam during cleaning and prevents the venti-
lation pipe from overflowing.
