Decalcification

In frosty conditions there is a risk that water
in pipes, faucets and appliances could freeze.
This can cause considerable damage.
• Do not decalcify the appliance in frosty
conditions.
Decalcification frequency
Lime scale occurs especially as a result of
precipitation from “hard” water. The appliance
must be decalcified regularly depending on wa-
ter hardness and hot water consumption.
