8. Initial operation
Before making the electrical connection, fill the mains and the appliance with
water by carefully opening and closing the hot water tap in order to vent
completely. After every draining (e.g. after work on the plumbing system or f
ollowing repairs to the appliance), the heater must be revented in this way before
starting it up again.
If the water heater cannot be put into operation, the temperature cut-out or the
pressure cut-out may have tripped during transport. If necessary, reset the
cut-out.
Selection of power rating
Only by authorised specialist, otherwise lapse of guarantee!
Upon first connection of the appliance to the supply voltage, select the maximum
power rating. Only after having set the power rating, the heater provides its
standard operation mode.
The maximum allowable power rating at installation site depends on the local
situ-ation. It is imperative to observe all data shown in the table “Technical specifi-
cations“, in particular the required cable size and fuse protection for the electrical
connection. Moreover, the electrical installation must comply with the statutory
regulations of the respective country and those of the local electricity supply
com-pany (Germany: DIN VDE 0100).

Switch on the power supply to the appliance. The digital display on the
appliance must light up.
2.

in the display. If not, please follow the below note “Reinstallation“.
3. Select the maximum allowable power rating depending on the local situation
via the up and down arrow keys (18 kW, 21 kW, 24 kW or 27 kW).
27 kW = red

Reinstallation
In case the appliance will be commissioned again under different installation
conditions than during its initial operation, it may be necessary to adapt the
maximum power rating.
A temporary short circuit of the two pins, e.g. with a screwdriver acc. to EN 60900
(see figure), will reset all heater parameters to works setting and lock the
heating. Value “21“ flashes in the display until the maximum power rating has
been selected. This condition will maintain when activating and deactivating the
supply voltage.
