Advantix bathroom drain
Calculate the height of the floor construction from the edge in the
inside of the drain up to the upper edge of the tiles.
Starting with the upper edge, transfer the measured height onto the
top.
Cut the top to the marked height.
If necessary, insert backflow seal in the lowest notch of the top.
INFO! The backflow seal be must employed when no damp-
ness is supposed to flow into the drain from outside of the
top but water may seep in from below. Normally, no backflow
seal is mounted so that water that occurs around the frame
(e. g. due to a leaky silicone joint) can flow away. A backflow
seal is mounted in the following cases:
– In the case of the risk of a build-up of water that can soak
through the screed.
– During the mounting of a stacking element for the bonded
sealing (see instructions for use of the stacking element).
Remove yellow protective plug.
Place the top into the drain and align according to the tiles.
Work the top into the screed or the floor covering.
