a) Fill the water deposit with 3 litres of water.
b) Connect the machine to the power supply.
c) Set the switch (12) to position 1. The red indicator light (13) will come on. This is followed by the
automatic filling of the boiler.
d) Set the switch (12) to position 2. The green indicator light (14) will come on.
Wait about 10 minutes until the working pressure is reached, as indicated by the green range on the gauge (10, 11). The
green indicator light (13) will go out.

General warnings

It is recommended that, once the working temperature has been reached, water is made to flow through
the groups for a moment in order to induce the thermosyphon current, thus enabling the system to reach
the ideal temperature to begin working.
It is also of the utmost importance that the filter holder structures are fitted to the groups, so that the
metal on the filter holders also reaches the necessary temperature to dispense correctly the first coffees.
When turning on the main switch, it must be put into position 1 before moving on to position 2.
While there is no pressure in the machine boiler or, similarly, if it is not yet hot, do not press the hot water
button. If it were pressed, cold water would be obtained.
2.3. DOSAGE OPERATION
It is important to remember that the buttons and control units receive signals in the two main switch supply positions on
the machine.
Position 1
2
1
In the first position, the switch will only operate the automatic water filling, but not the heating elements.
Position 2

1
In the second position, the switch receives a signal from the starter relay (optional) and this allows the machine to be
heated and dispense coffee. It is recommended that this be done when the machine is hot and the working pressure in
the boiler(s) has been reached, as indicated by the green range on the gauge (11), and/or shown on the display, if the
machine has one.
