2.2. PREPARATION AND START-UP

2.2.1. Stationary coffee machines

a) Open the water stopcock (23).
b) Connect the permanent thermo-magnetic switch (22).
c) Machines with single boilers: Press the switch of the machine (12) and wait until the automatic level
control finishes filling the steam/hot water boiler with water.
d) Machines with two boilers: Press the switch of the machine (12) and wait until the automatic level
control finishes filling the steam/hot water boiler with water. The coffee boiler will fill thanks to the mains
pressure (it is recommended that the non-stop coffee buttons (4) are pressed until water comes out of the
groups).
e) Set switch (12) to position 2 and the heating elements will begin to heat the water in the boiler. (Only
necessary on models with 3-position main switch. On models with 2-position main switches, the machine
will begin to heat when the level sensor is covered with water).
Wait until the working pressure is reached. The green indicator light (14) will go out. The boiler pressure gauge will
indicate the desired working pressure (0.08 - 0.1 MPa). In the case of the Iberital Expression Pro machine, the desired
working pressure is (0.1-0.12 MPa).

2.2.2. Portable coffee machines

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.
