Decalcification

The outlet pipe can be cleaned by means of usual decalcifier or vinegar. Please observe
manufacturer instructions when using decalcifier. In case water flows considerably
slowly when the hot water tap is opened the storage heater and the tap must be
decalcified by a professional. In case of permanent calcification an incorrect pressure
could develop inside the unit.
On the heating element and on the interior of the boiler scale is separating. The clean-
ing interval depends on the water hardness and the operating time of the appliance.
We suggest to clean the water storage heater after two years.
The appliance and the fittings should only be cleaned with a damp cloth. Do not
use abrasive or chlorine-based cleaning agents or solvents.
