Rough installation
Prepare the wall for the installation.
Prepare the holes for the wall mixer and slots for the
pipes.
Refer to the dimensional drawings on fold-out page I.
Install concealed mixer housing in wall and connect
pipelines, see fold-out page I, Fig. [1].
Part No. 20 019: Observe the correct installation
position! The cold water supply must be
connected on the right (marked blue on housing)
and the hot water supply on the left (marked red on
housing), as viewed from the operating position.
The installation depth of the finished surface of the
wall (A) must lie within the area (X) of the fitting
template, see Fig. [2].
By using a spirit level, align the mixer horizontally,
vertically and parallel to the wall.
Flush pipes thoroughly.
Open cold and hot-water supply and check

(maximum) 80 °C
nipple (G) to concealed mixer housing until the
(energy saving) 60°C
installation dimension reaches 34mm. Tighten the
cold - right
spout (H), using a 3mm socket spanner, see Fig. [7].
hot - left
Open cold and hot-water supply and check
connections for watertightness!
