LIFT-OFF SHUT-OFF
If you happen to lift the unit off the base station while boiling, the unit shuts itself
off. This is the so-called lift-off shut-off.
CLEANING
First pull the plug out of the electric socket and let the unit cool off.
Clean the exterior of the unit with a soft, moist cloth. If heavily soiled, you can
use a mild detergent.
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 distilled white vin-
●
egar 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.
