After every draining (e.g. after work on the plumbing system or following repairs to
the appliance), the heater must be re-vented in this way before starting it up again.
If the water heater cannot be put into operation, the temperature cut-out or the pres-
sure 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!
On delivery, the display shows the screen “APPROVED” (see left). If not, the device
has already been powered once. In this case, please follow the section “Reinstallation”.
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 situa-
tion. It is imperative to observe all data shown in the table “Technical specifications”,
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 company (Germany: DIN
VDE 0100).

The rated capacity (max. power con-
sumption) is 27 kW / 400 V and can be
changed internally to 24 kW, 21 kW or
18 kW.
6. Initial operation
In case the appliance will be commis sioned again under different installation conditions
than during its initial ope ration, it may be necessary to adapt the maximum power rat-
ing.
A temporary short-circuit of the two pins on the right, e.g. with a screwdriver acc. to
EN 60900 (see figure), will reset all heater parameters to works setting and lock the
heating. The display shows the menu to select the language. Choose your language,
after that the selection of power rating appears. This condition will maintain when acti-
vating and deactivating the supply voltage.
Reinstallation
The water heater’s temperature must be limited to 55 °C, if it is connected to a show-
er. The temperature limit must be set to a value less or equal 55 °C in the setting menu,
in consultation with the customer and the lock level must be activated.
When the device is operated with preheated water, it must be ensured that this tem-
perature is limited to 55 °C as well.
