3.4.10 The hydraulic circuit (for ROSSO)
The water feed circuit has the following configuration:
When the vending machine is connected to the water supply, the water runs in through an electromag-
netic valve with filter (2), when using the bottles, the water from the bottle is pumped using a primary pump
(1). Then the water enters the float chamber (3) and running through the water filter (4), water meter (5)
and boiler feed pump (6) reaches the boiler (7), where it is heated to the set temperature level and accord-
ing to the selected drink option it then runs into one of the two boiler channels: either through the selector
(9) to the mixer or to the espresso group (8), where the water is mixed with the required ingredient and the
drink is dispensed to the customer through the outlet nozzles (11). The excess of water and drink are then
discharged into the waste container (12).
