11. Commissioning
WARNING Electrocution
Commissioning may only be carried out by a qualified
contractor in accordance with safety regulations.
Note
During initial start-up and following prolonged power
supply interruptions (approx.8hours), you must set the
day of the week and the time.
11.1 Initial start-up
1. 2.
D0000049325
 Either open the DHW valve of the tap or set the mono lever
mixer tap to "hot" until the water that flows out is free of air
bubbles.
 Insert the plug into the standard socket or set the fuse/MCB
in the distribution board.
 Select a temperature.
 Check the entire hydraulic installation for tightness.
Note
If you fail to follow the correct sequence (first water, then
power), the boil-dry protection check will respond.
Boil-dry protection
The appliance PCB carries out a boil-dry protection check during
initial start-up and after every power supply interruption:
Red LED Illuminates for 20s Appliance heating up
Red LED 40s off PCB evaluation
During the boil-dry protection check, the "Heating enabled" sym-
bol flashes and the backlighting is switched on.
Note
During the boil-dry protection check ...
- the appliance must not be separated from the power
supply.
- no water may be drawn from the draw-off point.
Following a successful boil-dry protection check, the appliance
maintains a set temperature of 55°C.
Note
If the boil-dry protection check has responded, the fault
code "E1" is displayed. Any repeat start-up is blocked for
5 minutes.
Proceed as follows:
 Fill the appliance with cold water.
 After a blocking time of 5minutes, the appliance carries out
a new boil-dry protection check.
 If the fault continues to be displayed, reset the appliance
(P5= on).
11.1.1 Appliance handover
 Explain the functions of the appliance to the user. Show the
user how to operate the appliance.
 Make users aware of potential dangers, especially the risk of
scalding.
 Hand over these instructions and, if applicable, the instruc-
tions for any accessories.
11.2 Recommissioning
See chapter "Installation/ Commissioning/ Initial start-up".
12. Appliance shutdown
 Isolate the appliance from the power supply by removing the
plug or by tripping the MCB in the distribution board.
 Drain the appliance (see chapter "Installation/ Maintenance/
Draining the appliance").
