Hygiene flushing , see Fig. [30].
Hygiene flushing serves to ensure water hygiene if the fitting is
not used for a long time.
By touching the faucet and then pressing the button at the
control unit, a flushing for a period of 10 minutes takes place.
If the faucet is activated during this period, the flow will be
stopped, the hygiene flushing failed and has to be
restarted.
Maintenance
Inspect and clean all components and replace if necessary.
Shut off hot and cold water supply.
Remove battery and separate plug-in connectors,
see fold-out page II, Figs. [14] and [19].
I. Cartridge, see fold-out page III, Fig. [31].
Assemble in reverse order. When installing the cartridge,
ensure that the seals are correctly seated. Replace screws
and tighten alternately.
II. Pull out spray with non-return valve, see fold-out page III,
Fig. [32].
Assemble in reverse order.
III. Battery, see fold-out page II, Figs. [14] and [19].
The battery must be replaced at the latest 10 years after
putting the fitting into service.
A required change will be signaled by the indicator lamp of the
controller and by the faucet. Signaling occurs when using the
touch function
At low battery level, the indicator lamp flashes and the water
flow starts with three short bursts of water.
In case of an almost discharged battery, the indicator lamp
flashes and the water flow
stops after three short bursts of
water.
In case of a discharged battery, the indicator lamp flashes and
the water will
not flow.
Assemble in reverse order.
Insert battery with correct polarity.
IV. Solenoid valve, see fold-out page III, Figs. [33] and [34].
Assemble in reverse order.
V. Control, see fold-out page III, Figs. [33] to [35].
Assemble in reverse order.
VI. Check valve and filter, see fold-out page III, Fig. [36].
Assemble in reverse order.
