Digital automatic version dose programming: 2 groups
To program the doses on a system with 2 or more groups, follow the instructions
below:
1) For the first group, follow the same instructions of programming as indicated
for the 1-group machines until point 3 included. The yellow programming-LED
(n°3 fig.2) will be blinking.
2) Go to the next groups: press STOP and afterwards CONT (n°1 fig.2) without
releasing STOP as for a normal programming entry, press again CONT and the
green LED of the doses 1 LONG COFFEE and 2 LONG COFFEES (n°2 fig.2) as
well as the yellow programming-LED (n°3 fig.2) will be blinking. Press now 2
LONG COFFEES and only the green LED of the dose will remain alight.
3) Now go back to the first programmed group and press the STOP-key. The
transfer of the doses programming will be signalized by the red STOP-LED of
the first programmed group (n°4 fig.2) which will be blinking while the other
LEDs will turn off.
Start-up
Turn the switch knob to position 1.
If the machine is fitted with water level control, the boiler will be filled automatically (green indicator light turns off when filling completed).
If, however, the machine does not have a water level control, filling with water must be done manually (n° 14), checking the water level in the
boiler on the graduated visual level gauge which is provided with “minimum” and “maximum” references. Add water when the level gauge
approaches the “minimum” mark.
When the water in the boiler reaches the right level, set the main switch knob to position 2 to switch the heating element on. Wait until the machine
reaches working pressure (red indicator light off); open the steam tap for a few seconds and then close it again. Check that the boiler pressure
is around 0.9/1 bar. The boiler pressure can be regulated using the pressure switch (see page 7 for regulation). Make a coffee and check the
delivery pressure on the manometer: it should be 9 bars. The delivery pressure can be regulated by using the screw located on the pump bypass
(see page 7).
P semi-automatic version operation
Press the switch located above the selected group to start delivery. When the required quantity has been delivered, press the switch again to
stop it.
Digital automatic version dose programming: 1 group
1) Press the STOP-key of the group to be programmed and then, without releasing the STOP, press the CONT. push-button (n° 1 fig. 2). Entry to
the programming status is shown by the simultaneous blinking of the 4 green dose LED’s (n° 2 fig. 2) and the yellow programming- LED (n° 3 fig.
2) on the key-pad of the group being programmed.
2) Now press the delivery push-button for the dose that is to be programmed. The green LED for the dose being programmed will remain alight
and the yellow programming-LED will be blinking.
3)Press the STOP of that group when the coffee has reached the required level in the cup and the dose will be stored in memory. Other doses
can be programmed in the same way, the only difference being the key to be pressed.
4) Press STOP again to exit from the programming status.
Location and connections
Before installing the machine it is advisable to check the efficiency of the water mains (n° 10 fig.1), of the electrical connections (n° 1 fig. 1) and
of the gas mains (for gas-heated machines).
An electric cut-out (n° 2 fig. 1) with fuses rated for the machine’s electrical input is needed for the machine to be properly connected.
Attention: the earth connection (yellow/green wire) is mandatory.
Finally, the efficiency of the main drain pipe must be checked before it is connected to the machine’s drain pipe (n° 7 fig.1).
Hydraulic connections:
- Water inlet: pipe 3/8 union int. ø 10/12 mm.
- Drain - pipe: int. ø 16/17 mm.
Locate the machine on the shelf and find a suitable position for the water softener (n° 12 fig. 1). Connect the softener to the tap (n° 9) using the
pipe (n° 11 fig. 1). Connect the pipe (n° 13) to the water inlet (n° 5). Connect pipe (n° 7) to the drain tray (n° 6) and then to the main drain pipe
(n° 8). Place a recipient under the water softener's discharging pipe (see regeneration instructions page 10). Open tap (9) and run the water
through for a few minutes to clean the softener.
Make the electrical connections, connecting the power supply cord (n° 3 fig.1) to the mains line switch (n° 2).
If the machine is fitted with a gas system, connect it to the tap (n° 17 fig.1) using the pipe (n° 16) and adjust it as instructed.
