cappuccino. You can customise the settings of the machine to suit your
personal preferences and tastes.

therefore completely normal that there are traces of coffee in the mill.
This appliance is however guaranteed to be new.

USE
Preparation
Connect the appliance to the mains supply (see chapter ‘Installation’)
and switch on the appliance with the main switch (see ‘A’ page 5). The
first time you switch on the appliance with the main switch and every
time that it is plugged in, the appliance executes a “SELF-DIAGNOSIS”
action. Then the appliance switches off.
To turn it on, press the On/stand by button (Aa) on the left site
underneath the control panel.
• Coffee has been used to factory test the appliance and it is therefore
completely normal for there to be traces of coffee in the mill.
• Customise water hardness as soon as possible following the
instructions in the “Setting water hardness” section.
1. Start the appliance with the on/stand by button (see ‘Aa’). The
appliance displays ‘FILL TANK’ in different languages.
▷Extract the water tank, rinse and fill with fresh water without
exceeding the MAX line.
▷Replace and push as far as it will go.
2. Set the required language.
•When the message “PRESS OK TO SET TO ENGLISH” is
displayed, press and hold the touch key ‘Ok’ (5) for about 5
sec. If you set the wrong language, follow the instructions in the
“Setting the language” section. If your language is not available,
select one from those displayed. The instructions refer to the
English version. Then follow the instructions displayed.
3. Place a cup under the hot water spout. If the hot water spout is not
inserted, the appliance displays “INSERT WATER SPOUT”.
4. Place the hot water spout if it is not there.
The appliance displays: “HOT WATER PRESS OK”.
5. Press the touch key ‘OK’ (5) and after a few seconds a little water comes
out of the spout.
6. The machine now displays “TURNING OFF PLEASE WAIT” and
goes off.
7. Extract the appliance by pulling it out using the handles.

8. Open the lid and fill the container with coffee beans, then close the
lid and push the appliance in. The coffee maker is now ready for
normal use.
Only fill the water tank with cold water. Never use other liquids
such as mineral water or milk.
To prevent malfunctions, never fill with ground coffee, frozen or
caramelised coffee beans or anything else that could damage the
appliance.
• When using the appliance for the first time, you need to make 4-5
cups of coffee and 4-5 cappuccinos before the appliance gives
satisfactory results.
• Each time you turn the coffee maker on by the main switch (A), it
performs a “SELF-DIAGNOSIS” cycle and then goes off. To turn it
on again, press the On/stand by button (Aa).
Operation
Preparing coffee (using coffeebeans)
• The appliance is preset to make coffee with a normal taste.
You can also choose coffee with an extra mild, mild, normal, strong
or extra-strong taste. There is also a pre-ground coffee option.
• To choose the required taste, press more times the touch key
‘Coffee strength’ (2). The required coffee taste is displayed.
1. Place 1 cup under the spouts to make 1 coffee or 2 cups for
2 coffees.
2. Lower the spouts as near as possible to the cup for a creamier
coffee.
3. Press the ‘type of coffee’ touch key (3) to select the type of coffee:
•ESPRESSO
•MEDIUM CUP
•LARGE CUP
4. Press the ‘one cup of coffee deliver’ touch key (4) if you want to
make one coffee and the ‘two cup of coffee deliver’ touch key (6)
if you want to make two coffees.

USE
▷Once the set amount of coffee has been delivered, the machine
stops delivery automatically and expels the exhausted waste
coffee into the waste coffee container. After a few seconds, the
appliance is ready for use again.
Tips
• To turn the appliance off, press the ‘On-off’ button (Aa / see page 5).
Before going off, the appliance performs an automatic rinse cycle.
Take care to avoid scalds.
• If the coffee only comes out in drips or not at all, the knob for setting
the grind level must be turned by one position clockwise (see
“Setting the grind level”). Turn one click at a time until the coffee is
delivered satisfactorily.
• If the coffee comes out too fast and the cream does not meet your
taste, turn the knob by one position anti-clockwise). Make sure that
you do not turn the knob for setting the grind level too far, as coffee
may come out in drips when dispensing 2 cups.
• You can stop the coffee from dispensing by pressing the ‘One cup
of coffee deliver’ touch key (4) or ‘Two cup of coffee deliver’ touch
key (6) again.
• After the coffee has finished dispensing (the progress bar reaches
100%), you can change the amount of coffee (see ‘Changing the
quantity of coffee’).
• When the display shows the message “FILL TANK!”, you must fill the
tank, otherwise the appliance cannot make any coffee. It is normal
that there is some water left in the water tank when the message is
displayed.
Tips to make hotter coffee
• After 3 minutes since you last made coffee, you can preheat the
brewing unit by using the menu setting “RINSING (see ‘Rinsing’).
Run off the water into the underlying drip tray or alternatively use
this water to fill (and then empty) the cup to be used for the coffee.
• Do not use cups that are too thick, as they will absorb too much
heat.

EN 13
USE
Empty the waste coffee container
• The appliance counts the number of coffees made. Every 14 single
coffees (or 7 doubles) the appliance displays “EMPTY WASTE
COFFEE CONTAINER”. This means that the waste coffee container
is full and must be emptied and cleaned.
• As long as the waste coffee container is not cleaned, this message
remains in place and the coffee machine cannot make any coffee.
• To clean, open the service door at the front by pulling the coffee
spout, remove the drip tray, empty it and clean it.
Important!
Always completely extract the drip tray, to avoid that it falls when
removing the grounds container. Empty the grounds container and
clean thoroughly, making sure all residues deposited on the bottom
are removed.
Every time you pull the drip tray out, the waste coffee container
must also be emptied, even if it is not completely full. If this
process is not carried out, the waste coffee container may overfill
when coffee is made and the machine may get blocked.
Never remove the water tank when the appliance is dispensing
coffee. Otherwise, the appliance will not be able to make the
coffee. If the appliance malfunctions, do not contact the service
centre straight away, but first look at the troubleshooting guide. If
this does not help, contact the customer service.
Changing the quantity of coffee
The appliance is factory preset to automatically deliver the following
quantities of coffee:
•ESPRESSO
•MEDIUM CUP
•LARGE CUP

EN 14
USE
To change these quantities, proceed as follows:
1. Place a cup under the spouts.
2. Press the ‘type of coffee’ touch key (3) to select the type of coffee.
3. Keep the ‘one cup of coffee deliver’ touch key (4) pressed until the
message “PROGRAM QUANTITY” is displayed and coffee delivery
begins.
4. As soon as the coffee in the cup reaches the required level, press
the same icon again. The quantity set has now been programmed.
Setting the grind level
If coffee is dispensed too quickly or too slowly (in drips), you can
change the grind level.
Only change the grind level during the milling process. Otherwise,
the coffee machine may be damaged.
1. Extract the appliance by pulling it out using the handles.
2. Press the ‘one cup of coffee deliver’ touch key (4).
3. Open the coffee bean holder cover.
4. Turn the knob for setting the grind level anti-clockwise to obtain finer
ground coffee, slower delivery and a creamier appearance. Turn the
knob clockwise for coarser ground coffee and faster delivery (not a
drop at a time).
The adjustment will be evident after at least 2 cups of coffee are made.
