Maintenance - Grohe 36 325 Bedienungsanleitung

Selecting a programme
The programme is selected via the infrared sensor system.
1. Activate setting mode:
Disconnect the power supply to the electronics and reconnect
after 10 s, see Fig. [12]. Setting mode is active for 3 minutes.
2. Hold finger against the lower area of the sensor system, see
fold-out page III, Fig. [13].
The indicator lamp (N) in the sensor system flashes quickly.
3. Remove finger from the sensor system once the indictor
lamp goes out. Programme selection mode is activated.
4. Place finger against the lower area of the sensor system
again.
The programmes are displayed by groups of flashing signals
via the indicator lamp. The groups are separated by a pause.
5. Programmes and display:
Display starts with the programme that is currently set. The
number of flashing signals corresponds to the individual
programmes:
1 = Programme 1
Pause
2 = Programme 2
Pause
...
7 = Programme 7
Pause
After the group with 7 flashing signals, the routine starts
from the beginning.
1 = Programme 1
...
6. Selecting a programme:
The programme is selected by removing the finger from
the sensor system during the pause after the required
programme. The corresponding flashing signals are
displayed again after the finger is removed.
7. A new programme can be selected within the next 5 s if
required. Programme selection mode is automatically
terminated if the finger is removed from the sensor system
before 5 s have elapsed.
Starting cleaning mode
Cleaning mode is activated by holding the finger against the
lower area of the sensor system (indicator lamp lights up
continuously, then flashes). Remove the finger when the
flashing signals start.
Terminating cleaning mode
Cleaning mode can be prematurely terminated by once more
holding the finger against the lower area of the sensor system
(the indicator lamp changes from flashing signals to lighting
up continuously). The finger can be removed once the
indicator lamp goes out or cleaning mode ends automatically
after 3 minutes.

Signalling the remaining battery capacity and performing
thermal disinfection
Turn mixer lever to the hot water end stop.
Thermal disinfection is started and the remaining battery
capacity is signalled by holding the finger against the lower area
of the sensor system (indicator lamp lights up continuously, then
flashes slowly, then flashes quickly). Remove the finger when
the quick flashing signals start. The remaining battery capacity
is signalled as follows by the number of flashing signals:
4 = Remaining capacity > 60%
3 = Remaining capacity > 40%
2 = Remaining capacity > 20%
1 = Remaining capacity < 20%
Thermal disinfection starts once the remaining capacity has
been signalled.
The detection zone of the sensor system must be
kept clear while the remaining battery capacity is
being signalled.
If an object is detected during thermal disinfection (hot water
flow), the water stops flowing immediately and the fitting is
closed (indicator lamp starts to flash).
Closure of the fitting ends automatically after 3 minutes or can
be prematurely terminated (see Terminating cleaning mode).
The remaining battery capacity is always indicated
by 4 flashing signals during mains operation.

Maintenance

Shut off hot and cold water supply.
Disconnect voltage supply.
Inspect and clean all components and replace if necessary.
I. Battery (prod. no. 36 327, 36 330, 36 331), see fold-out
