Mounting conditions
The following requirements exist for the mounting of the drain / over-
flow:
n
The bathtub is installed.
n
The drainage line is installed all the way to the bathtub.
n
The underside of the bathtub is accessible.
Backflow situation: If a negative pressure situation should occur when
the bathtub is filled, there is a possibility that bath water may flow back
into the drinking water system.
To ensure that no bath water flows back into the drinking water system,
a pipe interrupter must be installed in the pipeline between the shut-off
fitting and the bathtub inlet.
The following schematic diagram shows what this should look like:
Fig. 2: Mounting scheme with pipe interrupter
It is important that the pipe interrupter is mounted at least 150 mm
above the top edge of the bathtub.
Observe the local standards and regulations.
The pipe interrupter is not included in the scope of delivery and must be
ordered separately. Observe the instructions for use of the pipe inter-
rupter.
