You can interrupt the heating process by setting the temperature
selector to "cold".

4.2 Rapid heating during dual circuit operation
For appliance types with dual circuit operation, the heating con-
tractor can install a pushbutton to control the rapid heat-up func-
tion remotely. If required, you can switch this on. The rapid heat-
up function switches off when the selected temperature has been
reached and will not switch on again.
5. Cleaning, care and maintenance
f
f
Have the electrical safety of the appliance regularly checked
by an electrician.
Scaling
f
f
Almost every type of water will deposit lime at high tempera-
tures. Limescale will settle inside the appliance and affect its
function and service life. The heating elements must there-
fore be descaled from time to time. A qualified contractor
who is aware of the local water quality will tell you when the
next service is due.
f
f
Check the taps/valves regularly. You can remove limescale
deposits at the tap outlets using commercially available des-
caling agents.
f
f
Regularly activate the safety valve to prevent it from becom-
ing blocked e.g. by limescale deposits.
