Decalcifying
Depending on the hardness degree
of the water, 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 decalcifying the unit as
follows
Fill the unit three-quarters full
‹
with water.
Boil it.
‹
After the unit has shut itself off,
‹
fill the unit additionally with dis-
tilled 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 instruc-
tions.
