3 - MACHINE DESCRIPTION

3.1 Description of working cycle

S/R Versions
The water coming from the water supply (R VERSION) or from the tank on the back of the machine (S
VERSION), via a vibration pump, passes through a excess pressure valve regulated to 12 bar (1.2 MPa)
and allows the boiler and the exchanger to be loaded. The boiler water, heated by a resistance, heats the
water in the exchanger in turn, from where it is sent to the unit via an electrically-controlled valve, using a
weight, that allows the water to pass through to produce coffee.
