IBERITAL
d) Machines with two boilers: Set the machine switch (12) to position 1 and wait until the automatic level control completes the fi lling of the steam/hot water boiler with water. The coff ee boiler will fi ll thanks to the mains pressure (it is recommended that the non-stop coff ee 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.
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 MPa - 0.1 MPa). In the case of the Iberital Expression Two machine, the desired working pressure is (0.1-0.12 MPa).
2.2.2. Portable coff ee machines (Iberital IB7 1GR - 2GR compact)
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 fi lling 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 fl ow 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 fi lter holder structures are fi tted to the groups, so that the metal on the fi lter holders also reaches the necessary temperature to dispense correctly the fi rst coff ees.
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.
SLIV
In the fi rst position, the switch will only operate the automatic water fi lling, 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 coff ee. 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.

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 coff ee 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, and the previous step to start programming will have to be repeated.
