Clean the DHW cylinder through the inspection port.
f
Never use descaling pumps. Never use descaling agents to
clean the enamel coating and protective anodes.
Replacing the protective anodes
Two protective anodes are installed in the DHW cylinder to protect
it against corrosion. One of the protective anodes has a consump-
tion indicator.
f
Check the protective anodes at regular intervals.
We recommend checking the protective anodes at the latest two
years after commissioning.

Replace the protective anodes when the colour of the
protective anode with the consumption indicator changes
