➢ MANOMETER M1 : BOILER PRESSURE
The boiler pressure is adjusted in factory between 0,8 MPa (12 PSI) and 1 MPa (15 PSI). This value varies
slightly around its nominal temperature, due to the PID system which controls the heating and limit the
current consumption to its minimum.
NOTE: An over-heating thermostat will cut the heating, in case of an abnormal high temperature.
➢ MANOMETER M2 : PUMP PRESSURE
The pump pressure is adjusted at 9 MPa in the factory. Value which allows the best extraction of coffee
flavors. A bypass system evacuates over-pressure.
NOTE: Simultaneous operation of all the groups can impact a little bit the pressure level.
Visualization of the presence of water network is done by consulting the gauge
