Grohe Essence Foot Control 30 311 Serie Instrucciones De Instalación página 9

Hygiene flushing, see Fig. [30].
Hygiene flushing serves to ensure water hygiene if the fitting is
not used for a long time.
By initiating the Foot Control function 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 again, 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. [10] and [20].
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. [10] and [20].
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
Foot control function
At low battery level, the indicator lamp flashes and the water
flow starts with three short bursts of water.
Fault Cause
Water not flowing • Water supply interrupted
Water flow does not • Water supply interrupted
start after usin the • Filter in solenoid valve blocked
Foot control • Plug-in connector of solenoid valve without
function contact
• Solenoid valve defective
• No voltage
- Battery discharged
- Plug-in connector without contact
• Sensor system not correctly adjusted to
ambient conditions
Water flowing • Solenoid valve defective
continuously • Sensor system not correctly adjusted to
ambient conditions
Undesired water • Sensor system not correctly adjusted to
flow ambient conditions
• Potential equalisation not provided
• Fitting not correctly calibrated
Flow rate too low • Mousseur dirty
• Filter in solenoid valve dirty
• Shut-off valves, service valves not fully open
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].
