2.6.1 Coffee boiler
Each dispensing group is equipped with a thermally
insulated coffee boiler (1) for coffee hot water dispensing.
Heat is provided by an electric heating element (2).
The boiler includes a tem-
perature sensor (3) and a
safety thermostat (4).
The temperature sensor
(3) regulated and stabilizes
the water temperature in-
side the coffee boiler. The
safety thermostat (4) in-
tervenes in the event of a
malfunction of the heating
system. After reaching 150
°C the safety thermostat
intervenes to disable the heating element and to report
the problem on the display.
2.6.2 Services boiler
The totally insulated services boiler (5) is used to
produce steam for hot water, for milk frothing with the
cappuccino maker or auto steamer (optional), and to
heat/foam beverages.
The water in the boiler is heated by an electric heat-
ing element (6).

Dispensing group
The dispensing group (A) is made up of a metallic
block which is hooked onto the coffee boiler (B).
The features of the group are summarized as follows:
• the activation of the motor pump and solenoid valve
(C) located on the side of the group allows the cold
water to enter the boiler (D), consequently the hot
water in the boiler is carried towards the dispensing
group (E);
• the electrical cartridge heating element (F) installed
in the group is controlled by an electronic control unit
and allows the group to be heated at a programmed
temperature;
• the temperature sensor (G) detects the value of the
temperature of the group and sends it to the elec-
tronic control unit;
• the activation of the safety thermostat (H) prevents
risks if there is a failure in the electronic system.
