Appliance description
You can use the appliance to supply one or several draw-off points.
The internal steel cylinder is coated in enamel and is equipped
with an anode to protect the inside of the cylinder against cor-
rosion. With all appliance versions, except SB 650/3 AC, the pro-
tective anode is equipped with a consumption indicator; a ther-
mometer is also supplied.

Cleaning, care and maintenance
f Have the electrical safety of the fitted accessories and the
function of the safety assembly regularly checked by a quali-
fied contractor.
f Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
4.1
Protective anode
Appliance versions, except SB 650/3 AC:
Signal anode with consumption indicator
Material losses
!
If the consumption indicator changes colour from white
to red, have the signal anode checked by a heating con-
tractor and if necessary replaced.

SB 650/3 AC
f Have the protective anode checked by a qualified contractor
after the first two years of use. The qualified contractor will
then determine the intervals at which it must be checked
thereafter.
4.2
Scaling
Almost every type of water will deposit lime at high temperatures.
This settles inside the appliance and affects both the performance
and service life. The heating elements must therefore be descaled
from time to time. A qualified contractor who knows the local
water quality will tell you when the next service is due.
f Check the taps regularly. Limescale deposits at the spouts
can be removed using commercially available descaling
agents.
f Regularly activate the safety valve to prevent it from becom-
ing blocked, e.g. by limescale deposits.
