5 - DESCRIPTION OF MACHINE

5.1 Description of operating cycle

The water arriving from the mains through a motor pump, adjusted to a pressure between 9 and 10
bar (0.9 – 1 MPa), passes through a pressure relief valve, adjusted to 12 bar (1.2 MPa), allowing both
the boiler and the heat exchanger to be filled. The water in the boiler, heated by a heating element, in
turn heats the water in the heat exchanger, which, thanks to a drip riser, is sent to the group in order to
brew the coffee by means of an electronically-controlled valve.
