Description of the Machine

Description of the Operating Cycle

Water from the reservoir is pumped through a pressure valve (12 bars for Sole, 9 bars for Luce) into the heat exchanger. The boiler is filled via a loading solenoid valve. The boiler heats the water, which in turn heats the water in the heat exchanger. This hot water is then sent to the group for coffee infusion.

Using the Machine

Machine Power-On and Boiler Water Filling

Reservoir (TANK) Operation

Fill the water reservoir up to the "MAX" mark.

! Use potable water (ideal hardness: 8/9°F French degrees). Never use hot water.

Ensure the tap at the bottom of the machine is set to "TANK" mode.

Mains Water Connection (NET) (Sole only)

To convert from reservoir to mains water supply, remove the reservoir and insert the sensor cover into the opening. Turn the tap at the bottom of the machine to "NET" mode.

Ensure the water supply line is connected to a potable water network with a service pressure between 0 and 6 bar (0.6 MPa). If the pressure exceeds 6 bar, install a pressure reducer. Install a shut-off valve upstream of the machine connection.

Connect the power cord. Press the switch (Fig. 01, pos. 1) to turn on the machine. The water filling process will start automatically.

! A safety device will interrupt the pump operation after 120 seconds if the maximum water level in the boiler is not reached. To reset, turn the machine off and on again.

Heating

To bring the machine to the correct temperature (boiler pressure between 1 and 1.2 bar), open the steam tap and discharge steam 2-3 times.

The white indicator light indicates water presence in the reservoir; if it is off, the water level is low.
