Dispensing assembly
The delivery group is composed as follows :
the group body (
1 ) is made up of a metallic block
which is hooked onto the coffee boiler ( 2 );
t 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 );
t
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;
t
the temperature sensor ( 7 ) detects the value of the
temperature of the group and sends it to the elec-
tronic control unit;
t
the activation of the safety thermostat ( 8 ) prevents
risks if there is a failure in the electronic system
