pulses is reached: 1flash pulse = 1second.
✓ The water flows while the IR sensor is
covered.
✓ When the IR sensor is released, the
green LED flashes (1x) and the water
stops. The tap is ready for operation
again.
Activating continuous flush
When the continuous flush is activated, the water
flows continuously for max. 10min.
Settings:

4Remove hand from the detection range of
the IR sensor.
✓ The detection range is remeasured.
✓ After the measurement, the green LED
lights up 1x. The tap is ready for
operation again.

Performing thermal disinfection
If the drinking water installation is contaminated
with microorganisms, it may be necessary to
disinfect the installation thermally. During this
process, the microorganisms in the water are killed
off by the effects of temperature.
The Geberit washbasin taps Piave and Brenta with
thermostatic mixer have a scald protection feature.
This limits the water temperature to 42°C. When
performing a thermal disinfection, the temperature
limitation feature in the thermostatic mixer must be
deactivated so the water temperature can be
increased.
During thermal disinfection, hot water (70°C)
needs to run for at least 3minutes at all points of
use.
1Detach the cover plate. → See illustration
sequence 1, page42.
2Deactivate temperature limitation. Press in
the spring with a screwdriver and open the
hand wheel all the way.
