5.5 How to make drip coee
Open the lter holder by rotating it towards the right (g.
7).
Fill the jug with fresh clean water up to the level indicated
for the number of cups of coee you want to make, taking
care not to exceed the MAX level (g. 8).
Then pour the water into the coee maker tank
(g. 9).
Insert the permanent lter in the lter holder (g. 10).
Place the ground coee in the lter using the measure pro-
vided and distribute evenly (g. 11). As a general rule, use
one level measure of coee (about 7 grams) for each cup
you want to make (for example, 10 measures for 10 cups).
Close the lter holder, close the jug with the lid and place it
on the warming plate.
Press the ON/OFF button. The light on the button indicates
that the coee maker is operating.
After a few moments, the coee starts percolating.
It is normal for the appliance to give o steam during operation.
Once brewed, to keep the coee warm, place the jug on the
warming plate and leave the appliance turned on (with the light
on the "ON/OFF" button on). The coee in the jug will be kept at
the right temperature.
To turn the appliance o, press the ON/OFF button.
6. MAKING ESPRESSO COFFEE
6.1 Preheating the coee unit
To obtain espresso coee at the right temperature, the coee
machine must be preheated:
1. Press the ON/OFF button (g. 12) to turn the appliance on.
The light comes on.
2. Place the lter in the lter holder (g. 13). Make sure the
projection on the lter is inserted correctly in the corre-
sponding slot. Attach the lter holder with lter to the
appliance (g. 14) without adding coee. Use the smaller
lter to make one coee or the larger lter to make two
coees.
3. Place a cup under the lter holder. Use the same cup as will
be used to prepare the coee in order to preheat it.
4. Wait for the light to come on, then immediately
turn the selector dial to the position (g. 15). Deliver
water until the light goes o, then stop delivery by press-
ing the same button and empty the cup.
(It is normal for a small and harmless pu of steam to be given
o when removing the lter holder).
6.2 How to make espresso coee using ground
coee
1. After preheating the appliance as described in the previous
paragraph, use the smaller lter to make one coee or the
larger lter to make two coees.
2. To make just one coee, place one level measure of ground
coee (about 7 g) in the lter. (g. 16). To make two cof-
fees, place two loosely lled measures (about 6+6 g) of
ground coee in the lter. Fill the lter a little at a time to
prevent the ground coee from overowing.
Important:
to ensure correct operation, before placing the ground coee in
the lter holder, clean the lter of ground coee residues left
from the previous brewing.
3. Distribute the ground coee evenly and press lightly with
the presser (g. 17).
background
10
Correct pressing of the ground coee is essential to obtain
a good espresso. If pressing is excessive, coee delivery
will be slow and the froth will be dark. If pressing is too
light, coee delivery will be too rapid and the froth will be
skimpy and light coloured.
4. Remove any excess coee from the rim of the lter holder
and attach to the appliance. Rotate rmly (g. 14) to avoid
water leaking out.
5. Place the cup or cups (ideally preheated by rinsing with a
little hot water) under the lter holder spouts (g. 18).
6. Make sure the
light is on (if o, wait until it comes
on), then press the
button (g. 15) until the required
quantity is obtained. To interrupt, press the button again.
7. To remove the lter holder, turn the handle from right to
left.
Danger of burns
To avoid splashes, never remove the lter holder while the ap-
pliance is delivering coee.
8. To dispose of the used coee, block the lter in place
using the lever incorporated in the handle, then empty
the grounds by turning the lter holder upside down and
tapping it rmly (g. 19).
9. To turn the machine o, press the ON/OFF button on the
left side.
6.3 How to prepare espresso coee using pods
1. Preheat the appliance as described in the section "PRE-
HEATING THE COFFEE UNIT", making sure the lter holder
is attached. This obtains a hotter coee.
Please note:
Use pods conforming to the ESE standard, indicated on the pack
by the following mark:
The ESE standard is a system accepted by leading
pod producers and enables espresso coee to be
prepared simply and cleanly.
2. Place the small one-cup or pod lter in the lter holder,
making sure the projection is correctly inserted in the cor-
responding slot as shown in g. 13.
3. Insert the pod, centring it as far as possible on the lter
(g. 20). Always follow the instructions on the pod pack to
position the pod on the lter correctly.
4. Attach the lter holder to the appliance. Always turn as far
as it will go (g. 14).
5. Proceed as in points 5, 6 and 7 in the previous section.
7. HOW TO PREPARE CAPPUCCINO
1. Prepare the espresso coees as described in the previous
sections, using suciently large cups.
2. Press the
button. The corresponding light comes on
(g. 21).
3. In the meantime, ll a recipient with about 100 grams of
milk for each cappuccino to be prepared. In choosing the
size of the recipient, bear in mind that the milk doubles or
triples in volume.
Please note:
You are recommended to use skimmed or semi-skimmed milk at
refrigerator temperature (about 5°C).
4. Place the recipient containing the milk under the cappucci-
no maker.
5. Wait until the light comes on (g. 21). The light comes
on to indicate that the boiler has reached the ideal temper-
ature for steam production. When the boiler is heating up,
it is normal for a small quantity of water and steam to be
delivered into the drip tray.
6. Extract the cappuccino maker by pushing upwards and ro-
tating it towards the left (g. 22). During this operation,
avoid touching the boiler outlet as it is hot. Then place the
recipient containing the milk under the cappuccino maker.
7. Dip the cappuccino maker in the milk for a few millimetres
(g. 23). Turn the steam dial to the ON position (g.
24). The milk now starts to increase in volume and take on
a creamy appearance;
8. When the milk has doubled in volume, immerse the cap-
puccino maker deeply and continue heating the milk.
When the required temperature is reached (60°C is ideal),
interrupt steam delivery by rotating the steam dial to the
OFF position and pressing the button.
9. Pour the frothed milk into the cups containing the coee
prepared previously. The cappuccino is ready. Sweeten to
taste and if desired, sprinkle the froth with a little cocoa
powder.
Please note:
To prepare more than one cappuccino, rst make all the
coees then at the end prepare the frothed milk for all the
cappuccinos;
To make coee again after the milk has been frothed, rst
cool the boiler, or the coee will be burnt. To cool, place a
container under the boiler outlet, press the button
(g. 15) and deliver water until the OK light goes o. Press
the button and make the coee as described in the previ-
ous paragraphs.
You are recommended to deliver steam for a
maximum of 60 seconds and never to froth
milk more than three times consecutively.

Over time, calcium in the water may cause obstructions, reduc-
ing the eciency of the coee maker. You are recommended to
descale the coee maker about every 40 coees. To descale, al-
ways use special commercially available descaling products for
drip coee makers.
1. Dilute the product in the jug, following the instructions on
the descaler pack;
2. Remove the chlorine lter and pour the solution into the
tank;
3. Place the jug on the warming plate;
4. Press the button, deliver the equivalent of one cup
then turn the appliance o;
5. Leave the solution to work for 15 minutes, then repeat op-
erations 4 and 5.
6. Turn the appliance on and deliver the water until the tank
is completely empty.
7. Rinse by operating the appliance with water only at least 3
times (3 complete tanks of water).
Important!
If you do not descale the drip coee unit, after prolonged use,
the ON/OFF light (B5) ashes and you can no longer make drip
coee. If this occurs, unplug the appliance from the mains sock-
et, then plug in again and perform two descaling cycles imme-
diately as described in the relevant section.
