3.1 Assembly information

3.1.1 Mounting conditions

The following requirements exist for the mounting of the drain / over­flow:

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.

Pipe interrupter

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.

Handling

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.
