Coffee Maker 2

Thank you for choosing this coffee machine. To get the very
best out of your new coffee machine it is advisable to read
these instructions before using the appliance. This is the only
way to ensure optimum results and maximum safety.
Using for the first time
Before using the machine for the first time, wash all the acces-
sories in warm soapy water and rinse. For the best tasting coffee
the internal circuits must be flushed through at least five times.To
flush through the espresso function follow the instructions in the
paragraph “How to prepare espresso coffee” using just water.
The filter function must be flushed through, at least twice follow
the instructions in the paragraph “How to prepare filter coffee”
using just water.
Installation
• Place the coffee maker on a flat work surface at a safe distance
from taps and sinks.
• Check that the voltage corresponds to that indicated on the
appliance rating plate.The appliance must always be connected
to a well-earthed socket rated at 10A minimum.The manufac-
turer is not liable for damage caused by inadequate earthing of
the appliance.
• In the event of incompatibility between the plug on the appli-
ance and the socket, have the plug replaced by a qualified pro-
fessional.
If the cable is damaged or requires replacing, contact a service
centre authorised by the manufacturer only.
• Never install the machine in an environment that can reach a
temperature less than or equal to 0°C (if the water in it
freezes, the coffee maker may be damaged).

How to prepare filter coffee
Preparing the filter coffee
• Lift the lid and fFill the tank with fresh, clean water (Fig. 1) up to
the level marker corresponding to the number of cups of coffee
being prepared, making sure not to exceed the MAX mark.
• Open the filter holder door by turning it to the right (Fig. 2).
• Place the paper filter in the filter holder (Fig. 3).The use of size
“4” paper filters is recommended.
• Place the ground coffee in the filter using the measuring spoon
supplied, level evenly (Fig. 4).
As a general rule, use a level measure of coffee (about 7
grams) for each cup required (for example, 10 meas-
ures for 10 cups).
• Close the filter holder door and place the carafe, with the lid
on, on the hot plate.
• Select the desired flavour as described in the paragraph “How
to choose the flavour of the filter coffee”
Note: the coffee maker features the Flavour Saver device inside the
filter holder for filter coffee; this increases the coffee brewing time
and improves extraction, giving the coffee a full and intense flavour.
•Press the FILTER COFFEE ON/OFF switch (Fig. 5).The FILTER
COFFEE ON light above the switch will come on to indicate
that the filter coffee maker is working.
• The coffee will start to come out after a few seconds.
It is completely normal for the appliance to release a little
steam while the coffee is filtering.
To k eep the coffee hot after filtering, place the carafe on the hot
plate and leave the machine on (filter coffee light on): the coffee in
the carafe will be kept at the right temperature.
• To switch the machine off, press the FILTER COFFEE ON/OFF
switch.

Replace the tank by connecting the valve at the bottom of the tank
with the hole in the base on the machine.
The tank may also be filled without it being removed by filling with
water from a carafe.
NB: Never use the appliance without water in the tank and always
remember to top up when the level drops to a couple of centimetres from
the bottom (fig. 7).
PREHEATING THE COFFEE UNIT
To obtain espresso coffee at the right temperature, the coffee machi-
ne must be preheated.You are therefore recommended to press the
ON/OFF button (fig. 8) at least 15 minutes before preparing the cof-
fee, making sure the filter holder is attached to the applian-
ce (check that the steam knob is closed).
To attach the filter holder, position it under the boiler outlet with
the handle towards the left (see fig. 9), push it upwards and at the
same time rotate the handle firmly towards the right.Wait for 15
minutes, then make the coffee as described in the following chapter.
Alternatively, you can preheat more rapidly by proceeding as follows:
1. Turn the appliance on by pressing the ON/OFF button (fig. 8) and
attach the filter holder to the appliance without adding ground
coffee.
2. Place a cup under the filter holder. Use the same cup as will be
used to prepare the coffee in order to preheat it.
3. Wait for the temperature OK indicator light to come on (fig. 10),
then immediately press the coffee knob (fig. 11). Run the water off
until the temperature OK indicator light goes out, then interrupt
delivery by pressing the coffee button again.
4. Empty the cup. Wait until the temperature OK indicator light
comes on again then repeat the same operation.
(It is normal for a small and harmless puff of steam to be given off
when removing the filter holder).

How to prepare espresso coffee using the filter
holder for ground coffee
1. After preheating the appliance as described in the previous para-
graph, place the ground coffee filter in the filter holder Fig. 12.
Note: Use good quality, finely-ground coffee for espresso coffee machines.
IMPORTANT: for correct operation, before adding the
ground coffee to the filter holder, make sure the filter is
free from ground coffee from the previous infusion.
2. To make one coffee only, place one level measure (about 7 g) of
ground coffee in the filter (fig. 13).To prepare two coffees, place
two loosely filled measures (about 6+6 g) of ground coffee in the
filter. Fill the filter a little at a time to prevent the ground coffee
from overflowing. Distribute the ground coffee evenly and press
lightly with the presser (fig. 14).
NOTE:Pressing the coffee is very important in order to prepare
a good coffee. However if you press too hard, coffee will come
out slowly and crema will be of a dark colour. If you press too
light, coffee will come out too fast and crema will be a very light
colour.
3. Remove any excess coffee from the rim of the filter holder and
attach to the appliance. Rotate firmly (fig. 9) to avoid water
leaking out.
4. Place the cup or cups (ideally preheated by rinsing with a little
hot water) under the filter holder spouts (fig. 15).You are rec-
ommended to heat the cups before making the coffee by rinsing
them with a little hot water or placing them to warm on the
top plate for at least 15-20 minutes (fig. 16).
5. Make sure the temperature OK indicator light (fig. 10) is on (if
off, wait until it comes on), then press the coffee run-off button
(fig. 11) until the required quantity is obtained.To stop run-off,
press the coffee run-off button again.
6. To detach the filter holder, turn the handle from right to left.
To avoid any splashing, do not detach the filter holder
while the machine is dispensing coffee.
7. To eliminate the used coffee grounds, hold the filter holder
upside down and tap (fig. 17).

How to make cappuccino
1. Prepare espresso coffee, using cups that are large enough for cap-
puccinos
2. Press the steam ON/OFF button (fig. 18).The steam light comes
on (fig. 18).
3.Wait until the temperature OK indicator light comes on (fig. 19)
indicating that the boiler has reached the ideal temperature for
steam production.
In the meantime, fill a recipient with about 100 grams of milk for
each cappuccino to be prepared.The milk must be at refrigerator
temperature (not hot!). In choosing the size of the recipient, bear
in mind that the milk doubles or triples in volume.
NB: YOU ARE RECOMMENDED TO USE SEMI-SKIMMED MILK AT
REFRIGERATOR TEMPERATURE.
4. Place the container with the milk under the cappuccino maker.
5. Move the cappuccino maker outwards by rotating to the left (fig.
20). During this operation, avoid touching the boiler outlet as it is
hot. Place the recipient containing the milk under the cappuccino
maker.
6. Immerse the cappuccino maker in the milk for about 2 cm and rotate
the steam knob anticlockwise (fig. 21) (rotating the knob more or less
varies the quantity of steam delivered by the cappuccino maker).The
milk now starts to increase in volume and take on a creamy appearan-
ce.
7. When the required temperature is reached, interrupt steam delivery
by rotating the steam knob clockwise.
8. Pour the frothed milk into the cups containing the espresso
coffee.Your cappuccino is now ready. If desired, add sugar and
sprinkle a little powdered chocolate or cinnamon on top of the
froth.
Note: to prepare more than one cappuccino, first make all the cof-
fees then at the end prepare the frothed milk for all the cappuccinos.
IMPORTANT: to ensure hygiene, you are recommended to
follow this procedure each time you make cappuccino to avoid
milk stagnating in the milk circuit.
1. Discharge a little steam for a few seconds by rotating the steam
knob (fig. 21).This empties any milk left inside the steam tube.
2. With one hand, hold the top part stationary (taking care to avoid
burns) and with the other remove the cappuccino maker and
extract it from the nozzle(fig. 22).
3. Wash the cappuccino maker and steam nozzle thoroughly with
warm water.
5. Replace the cappuccino maker by inserting it as far as it will go
into the steam nozzle.

HOT WATER PRODUCTION
1. Turn the appliance on by pressing the espresso coffee ON/OFF
button (fig. 8).
2. Place a container under the cappuccino maker.
3.When the temperature OK light comes on, press the coffee run-
off button (fig. 11) and at the same time turn the steam knob anti-
clockwise (fig. 21).Water comes out of the cappuccino maker;
4. To interrupt the flow of hot water, close the steam knob by rotating
clockwise and press the coffee button again.
Cleaning and maintenance
Before performing any cleaning or maintenance operations, turn
the machine off, unplug it from the power socket and allow it to
cool down.
1. Do not use solvents or detergents when cleaning the coffee
maker.A soft, damp cloth is sufficient.
2. Remove the filter-trays, empty them and wash them periodically.
ATTENTION: during cleaning, never immerse the unit in
water – it is an electrical appliance.
Cleaning the filter holder for ground coffee
About every 200 coffees, clean the filter holder of ground coffee as
follows:
• Remove the filter and frother by turning the filter holder upside
down and tapping;
•Clean the inside of the filter holder. Never wash in a dishwasher.
•Clean the metal filter thoroughly in hot water using a brush (fig.
23. Make sure the holes in the metal filter are not blocked. If
necessary, clean with a pin (see fig.24).
•Separate the two parts of the frother and rinse under hot water
(fig. 25).
•Replace the rubber diaphragm, making sure it adheres well to the
plastic support.

Descaling the espresso coffee section
It is advisable to clean the calcium from the machine every 200
cups of coffee. It is recommended to use specificproducts for
descaling of espresso coffe machines.
1. Fill the water tank (espresso coffee) up to the MAX level;
2. Dissolve 2 spoonfuls (about 30 grams) of citric acid (obtainable
from chemist's or drug stores);
3. Press the espresso coffee ON/OFF button and wait for the tem-
perature OK indicator light to come on.
4. Make sure the filter holder is not attached and position a recipient
under the outlet.
5. Press the coffee run-off button and run off half the solution in the
tank.Then interrupt by pressing the same button again.
6. Leave the solution to work for about 15 minutes, then run off the
rest of the water in the tank.
7. To eliminate residues of solution and scale, rinse the tank well, fill
with clean water and replace in position.
8. Press the coffee run-off button and allow the water to run off until
the tank is completely empty;
9. Press the coffee run-off button and repeat operations 7 and 8
again.
Repair of damage to the coffee machine caused by scale is not
covered by the guarantee unless descaling is performed
regularly as described above
fig. 27
fig. 26

Descaling the filter coffee section
Formation of scale depends on the hardness of the water and on
how often the coffee machine is used.To obtain optimum perform-
ance, the appliance should be descaled regularly, at least every 40
cycles.
To descale, proceed as follows:
1. Fill the carafe with four cups of water;
2. Dissolve two spoonfuls (about 30 grams) of citric acid (available
from chemists or drug stores) in the carafe and pour the solu-
tion into the water tank.
3. Place the carafe on the hot plate and the filter holder without
ground coffee.
4. Filter the equivalent of two cups then turn the appliance off.
5. Leave the solution to work for 15 minutes, then repeat steps 4
and 5 once again.
6 Turn the appliance on again and allow the rest of the solution
to filter.
7 Rinse by operating the appliance with water only at least three
times (a full carafe each time).
Repairs for malfunctioning caused by problems of calcium
build-up are not covered by the guarantee if the descaling
process described above is not carried out regularly.
