with cold drinking water only.
When connecting the machine to the water mains, install a tap between the machine and the mains so as to be able
to interrupt the supply of water to the appliance.
To prevent the water from freezing, install the softener in a room where the temperature is higher than 0°C.
Before connecting the pipes remove any rubber plugs from the softener tap couplings. To connect proceed as
follows:
1) connect the water mains (1) to the softener inlet (2) using the flexible pipe provided;
2) before connecting the outlet of the softener to the machine, rinse the resins of the softener and check that the water,
which originally may be yellowish, is once again clear;
To prevent damage of the outer case, valves and taps, install the softener where it is protected
against accidental knocks.
3) connect the softener outlet (3) to the ma-
chine (4);
4) connect the machine drainage trough (5)
to the drain (6) using the specific pipe pro-
vided, paying attention to avoid sharp bends
or throttlings and keeping it slanted enough
for the waste water to drain away;
5) the drain (6) has to connected to an inspec-
tionable trap (7) that can be cleaned regu-
larly to prevent the reflux of bad smells.

Turn the programming key clockwise. This key is located on the right of the control panel. The display will show the
letter "P", to indicate that the machine can be programmed.
Once the letter P shows on the display, press and hold the MODE key for about five seconds until the display
shows the message "PROGRAMME GRINDING".
 Press the MODE key until the display shows the message "PROG. DOSES"
 Depending on the type of beverage selected, refer to one of the points mentioned below.
1. COFFEE SELECTIONS PROGRAMMING (with no added water)
 Press the key of the desired selection to activate the grinding and delivery cycle.
 Once the desired dose of coffee has been reached, press the same key again to stop programming.
 Re-programming is possible at any time by repeating the procedure described above.
During programming, if the programming of the coffee dose is stopped using the STOP key , the machine
will not memorize the dose that has just been memorized but instead will retain in memory the last dose previ-
ously memorized.
2. COFFEE SELECTIONS PROGRAMMING (with added water)
Press the key of the desired selection to activate the grinding and delivery cycle.
Once the desired amount of coffee is reached, press the same key again and the machine will stop delivering coffee
and it will automatically start delivering water. Once the desired amount of water is reached, press the selection key
again to stop delivery.
In this way the machine will have memorized both the amount of coffee and the amount of hot water (added water).
Re-programming is possible at any time by repeating the procedure described above.
To exit programming, repeatedly press the MODE key until the display show the message "SELECT".

3. PROGRAMMING COFFEE AND MILK / CAPPUCCINO SELECTIONS
By pressing the key for the desired selection, the phase of milk suction and heating by the cappuccino maker will
be started. Once the desired dose of milk is reached, press the same key again. The machine will stop milk delivery,
and it will memorize the time required for the suction of that amount. It will also activate the coffee grinding and delivery
cycle. Once the desired dose of coffee is reached, press the same key again. The machine will stop delivery of coffee
and it will memorize the amount reached.
4. PROGRAMMING OF MILK DOSES AND FOAMED MILK
By pressing the key for the desired selection, the phase of milk suction and heating by the cappuccino maker will be
started. Once the desired dose of milk is reached, press the same key again. The machine will stop milk delivery, and
it will memorize the time required for the suction of that amount.
5. PROGRAMMING DOSES OF HOT WATER
Pressing the hot water selection key will activate the solenoid valve for tea delivery. Once the desired dose is reached,
press the same key again.
The machine will stop delivery and it will memorize the time required for delivery. The dose can be re-defined at
any time.
6- STEAM TIME PROGRAMMING (optional)
By pressing the steam key (if present), machine will activate the solenoid valve, and steam delivery will begin.
By pressing the same key again, the machine will stop delivery and it will memorize the time required for delivery.
The operation can be repeated at any time.
7. PROGRAMMING DOSES OF MILK WITH A SHOT OF COFFEE (LCL)
a) Cold milk with shot of coffee
Press the key for the selection of cold milk with a shot of coffee. The display will show the message
"PROG. MILK WITH SHOT OF COFFEE F.".
Cold milk delivery will begin.
Once the desired dose has been reached, press the same key again. The machine will stop delivery of cold milk,
memorize the time required for delivery and will automatically start delivery of hot foamed milk. Upon completing the
dose of hot foamed milk, press the same key again, and the machine will stop and memorize delivery. The coffee cycle
will start automatically. Once the desired dose of coffee is reached, press the same key again. The machine will stop
coffee delivery and programming of cold milk with a shot of coffee will be complete.
Programming can be repeated at any time by following the procedure indicated above.
By changing the amount of cold water mixed with the hot water, the amount of water delivered changes as well.
Before programming it is therefore advisable to determine the correct temperature of the hot water.

"PROG. MILK WITH SHOT OF COFFEE C." and delivery will begin of non-foamed hot milk.
Once the desired dose is reached, press the same key. Delivery of non-foamed milk will stop, the machine will
memorize the time required and delivery of hot foamed milk will start automatically. Once the desired dose is reached,
press the key referred to above. A pause will be activated.
Once the desired pause time has elapsed, press the same key again and coffee delivery will start. Once the desired
amount of coffee is reached, press the same key again to stop delivery and memorize the dose.
Programming can be repeated at any time by following the procedure indicated above.
All decaf doses will automatically assume the value of the corresponding non-decaf dose, and will not be
programmable separately.
E.g. 1 ESPRESSO DECAF GR1 will have the same dose as 1 ESPRESSO GR.1 .
By modifying the dose of the espresso gr.1 you will also automatically modify the dose of espresso decaf
gr.1 in the same way.
6.9 Adjustment of doses
In this section of programming it is possible to modify the previously established dose, without re-programming, but
modifying the amount of water used by the machine for each coffee selection or modifying the time memorized by the
machine for each delivery of milk, hot water, etc.
To modify dose parameters, proceed as follows:
Turn the programming key clockwise. This key is located on the right of the control panel. The display will show the
letter "P", to indicate that the machine can be programmed.
 Once the letter "P" shows on the display, press and hold the MODE key for about five seconds until the display
shows the message "PROGRAMME GRINDING."
 Press the MODE key until the display shows the message "DOSE ADJUSTMENT"
 Press the key assigned to the selection for which you want to adjust or modify the dose.
If the selection is a coffee without added water, proceed as follows:
 Press the key for the selection of which you wish to modify the dose. The display will show the volume of water in
c.c. calculated by the volumetric dosing device for that particular selection. E.g. "C. DOSE 1 ESPRESSO GR1 CC
NNN".
 Use the ARROW keys to modify the amount of water used for the specific selection.
 To memorize the modified dose, press ENTER .
