2.8.19 Autosteamer (optional)
The “Autosteamer” system - fitted on some versions with a
display - enables milk to be automatically frothed at the pro-
grammed temperature. The operating principle of the Au-
tosteamer is listed below:
• Press the (AUTOSTEAM) button on the right
pushbutton;
• The solenoid valve opens (A) which conse-
quently allows the steam to flow from the
heating unit to the Autosteamer nozzle;
• The system simultaneously activates the air suction pump
(B) which is controlled by the control unit (C) and powered
by the transformer (D). The milk froth can be adjusted by
changing the amount of air intake when opening the valve
(E).
• After the air has passed through the non-return valve (F), it
mixes with the steam in the mixing interface (G).
• Steam comes out of the nozzle (H);
• The probe (H) that is connected to the machine’s electronic
control unit, detects the temperature of the milk while it is
being heated;
• Once the set milk temperature has been reached, the
electronic system stops the air and steam from being dis-
pensed.
To adjust the milk temperature and froth, see para.
