The bacteria is eliminated by bringing the stored water to a tempera-
ture exceeding 50°C/55°C.
It is therefore recommended that the DHW temperature selection
knob be set to the maximum value at least every 2/3 days to bring
the water temperature to 63°C, maintaining this temperature for at
least 5 minutes.

Clean the external boiler panels only, using a damp, soapy cloth.
For stubborn stains, dampen the cloth with a 50% water and dena-

Never use fuel and/or sponges soaked in abrasive solutions or
powder detergents.
Do not clean the boiler without having disconnected it from the
mains power supply, by setting the power switch to “off”.
