Decalcifying
Depending on the hardness degree of the wa-
ter, lime scale can build up over time on the
bottom and on the interior wall of the stainless
steel tank. The harder the water, the faster the
lime scale builds up. That is harmless but it can
impair the performance of the unit.
For that reason, we recommend regularly de-
calcifying the unit as follows
• Fill the unit three-quarters full with water.
• Boil it.
• After the unit has shut itself off, ll the unit
additionally with distilled white vinegar up to
the MAX mark.
Important
Never boil this mixture!
• Let the mixture stand overnight.
• Empty the unit and rinse it out several times
with clear water.
Important
You can use other suitable descalers. To do
that, follow the manufacturer‘s instructions.
