Flushing technology
The drain valve was developed for the dual flush technology with a small and a large flush volume. The small and large flush volumes are actuated by pressing the small or the large button in the flush plate.
Factory settings of the flush volume
Immediate re-flushing is possible because the cistern is not emptied completely.
The small flush volume is set to approx. 3 l.
The large flush volume is set to approx. 6 l.
If required, both flush volumes can be increased. For setting the flush volume, see: Setting the flush volume
Handling
General mounting instructions
INFO!
When you intend to install a new flush plate after retrofitting to the new flush valve, the parts of the existing flush plate can be discarded after dismounting.
Assembly
Setting the flush volume
Before mounting the drain valve set, set the flush volume at the drain valve as follows:
-
Set the small flush volume at the slide control at the side of the overflow pipe.
Slide control in top position: approx. 3 litres
Slide control in bottom position: approx. 4 litres
-
Set the large flow volume at the slide control at the bottom of the drain valve.
Slide control in left position: approx. 6 litres
Slide control in right position: approx. 9 litres
