d) Machines with two boilers: Set the machine switch (12) to position 1 and wait until the automatic
level control completes the filling of 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.
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.
In the first position, the switch will only operate the automatic
water filling, but not the heating elements.
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.
NOTE: If our model only has a 2-position main switch (ON-OFF), when it is switched on the boiler will begin to
fill, if not already full. When the machine detects that the minimum level of water has been reached, it will begin
to heat the water to make the coffee.
2.3.1. Programming dose on the control unit (not available on semi-automatic versions)
In order to program the dose you must press the 'non-stop' button on the left button pad (group 1) for 5 seconds,
and the non-stop coffee LED will come on (*).
NOTE: If you have already entered programming mode and do not press any button to indicate a dose within 30
seconds, the button pad will go to stand-by position.
