Multiple Power System MPS®:
The rated capacity (max. power consump-
tion) is 27 kW / 400 V and can be changed
internally to 24 kW, 21 kW or 18 kW.
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 com-
pletely.
To ensure a maximum flow, remove any existing aerator from the faucet. Flush
the warm and cold water pipes each at least for one minute.
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!
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).
1. Switch on the power supply to the appliance. The digital display on the appliance
must light up.
