4.3 Dispensing group
The dispensing group is composed as follows:
• the group body (1) is made up of a metallic block
which is hooked onto the coee boiler (2);
• the activation of the motor pump and solenoid valve
(3) located on the side of the group allows the cold
water to enter the boiler (4), consequently the hot
water in the boiler is carried towards the delivery
group (5);
• the electrical cartridge heating element (6) 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 (7) detects the value of the
temperature of the group and sends it to the elec-
tronic control unit;
• the activation of the safety thermostat (8) prevents
risks if there is a failure in the electronic system
