1 Partial load
At low throughput 1/3 of the heating output is activat-
ed; at higher throughput 2/3 of the available heating
output is enabled. This setting is suitable for hand
washing at a basin, for example.
2 Full load
At a low throughput, 1/2 of the heating output is ap-
plied; at a higher throughput the full heating output is
activated. This setting is suitable for washing dishes,
for example.

Note
If the outlet temperature is not sufficiently high at
full load and with the draw-off valve fully open, then
more water is flowing through the appliance than
can be heated by the heating system (appliance is
at its output limit).
» Reduce the water volume at the draw-off valve.

!
Following an interruption of the water supply the ap-
pliance must be recommissioned by carrying out the
following steps, in order to prevent the destruction
of the bare wire heating system.
» Disconnect the appliance from the power sup-
ply by removing the fuses/tripping the MCBs.
» Open the tap for one minute until the appliance
and its upstream cold water inlet line are free of
air.
» Switch the mains power back on again.
5. Cleaning, care and
maintenance
» Never use abrasive or corrosive cleaning agents. A
damp cloth is sufficient for cleaning the appliance.
» Check the taps regularly. Limescale deposits at the
tap outlets can be removed using commercially avail-
able descaling agents.
