3 - MACHINE DESCRIPTION
3.1 Machine Operating Cycle
R version
The water coming from the water supply by means a vibration pump passes through an overpres-
sure valve set to 12 bar (1,2 Mpa) to refill the boiler and the heating exchanger. The boiler water
heated by a resistance, heats in its turn the water in the exchanger, which, by means of a suction
lift, goes directly into the group which, by a solenoid valve allows the water to get in to supply
coffee.
S version
The water coming from the tank by means a vibration pump, passes through an overpressure valve
set to 12 bar (1,2 Mpa) to refill the boiler and the heating exchanger. The boiler water heated by
a resistance, heats in its turn the water in the exchanger, which, by means of a suction lift, goes
directly into the group which, by a solenoid valve allows the water to get in, to supply coffee.
