3 Handling
3.1 Assembly information
3.1.1 Mounting conditions
The following requirements exist for the mounting of the drain / over‐
flow:
nThe bathtub is installed.
nThe drainage line is installed all the way to the bathtub.
nThe underside of the bathtub is accessible.
Backflow situation: If a negative pressure situation should occur when
the bathtub is filled, bath water may flow back into the potable water
installation.
To ensure that no bath water flows back into the potable water installa‐
tion, a pipe interrupter must be installed in the pipeline between the
shut-off valve 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 vertically, in the
direction of flow and at least 150 mm above the upper edge of the
bathtub.
Observe the local standards and regulations.
