Additional Ventilation Of The Drain Section (Optional) - Rational iCombi Pro Original Installation Instructions

9.3

Additional ventilation of the drain section (optional)

Overflow of the unit due to external siphon
The unit is already equipped with an integrated siphon. A second, external
siphon (p trap) without ventilation of the drain section can cause the unit to
overflow.
No external siphon may be connected to the wastewater connection without
upstream ventilation.
Make sure that there is a free outflow zone or vent at the wastewater
connection.
Regular cleaning of the funnel
The funnel on the ventilation pipe must be cleaned at regular intervals. The
funnel must be removed from the ventilation pipe for cleaning.
Odor formation due to unused ventilation line
Odor formation may occur if a ventilation pipe is installed for safety due to
an unknown waste water line. This occurs when no external siphon is
installed in the wall.
The ventilation pipe is not required.
n
Remove the ventilation line with the ventilation pipe.
n
Connect the waste water line according to the specifications.
n
If an external siphon is connected, the unit requires additional ventilation of the
drain section via a vent pipe which is attached to the drain pipe and prevents the
unit from overflowing. This vent pipe is provided with holes (1) in the lower
area to achieve a suction effect.
