9.3 Additional aeration of the drain (optional)
NOTICE
Unit overflowing through external siphon
The unit is already equipped with an integrated siphon. A second external
siphon without aeration of the drain will cause the unit to overflow.
No external siphon may be connected to the drain connection without
upstream aeration.
You must ensure that there is a free outlet section and vent for the drain
connection.
NOTICE
Regular cleaning of the funnel
The funnel on the vent pipe must be cleaned at regular intervals. The funnel
must be removed from the vent pipe for cleaning.
NOTICE
Odour formation due to unnecessary ventilation section
If a vent pipe is installed for safety reasons due to an unknown wastewater
section, an odour may form. This is the case if there is no external odour
trap installed in the wall.
n
The vent pipe is not necessary.
n
Remove the ventilation section with the vent pipe.
n
Connect the wastewater section according to the specifications.
If an external siphon is connected, the unit requires additional aeration of the
drain via a vent pipe, which is connected to the drain pipe and prevents the
unit from overflowing. This vent pipe is provided with holes in the lower area
(1), in order to achieve a suction effect.
