8. USE
If ground coffee is left on the rim of the filter,
a leak tight seal is not ensured, and water or
coffee grounds may leak out of the filter.
Lock the filter-holder into the dispensing group firmly
to obtain a leak tight seal.
Place the cups under the spouts; begin dispensing
using control 3 or button panel 4 according to model
(Fig. 8).
When the coffee has been poured, leave the filter
holder attached to the dispensing group until the
next coffee is required.
When pouring, beware of the hot parts of the
machine, especially the coffee dispensing
units and the steam and hot water spouts. Do
not put your hands under the spouts or the
groups while they are operating.
8.2. Preparing cappuccino (Fig. 9)
· Make a cup of cappuccino with the espresso coffee.
· Use a tall, narrow frothing pitcher, half-filled with milk.
· Place the pitcher under the spout so that the nozzle
touches the bottom.
· Turn the steam knob and lower the pitcher so that
the nozzle is just under the surface of the milk.
· Now slowly lower the pitcher as the foam rises,
always keeping the nozzle slightly immersed in the
milk until you have sufficient froth.
· Turn off the steam knob and pour the frothed milk
into the waiting cappuccino cup.
Immediately after carrying out this operation, clean
the spout with a sponge or a clean cloth so that the
milk does not dry on it. Be careful - the spout is hot
and may burn your hand.
8.3. Heating a beverage
Immerse the steam spout into the liquid to be
heated.
Gradually turn the steam knob(Fig.8 - 7); the
steam that disperses into the liquid heats it to
the desired temperature.
Turn off the steam knob when the desired temperature
has been reached.
Immediately after carrying out this operation, clean
the spout with a sponge or a clean cloth so that the
milk does not dry on it. Be careful - the spout is hot
and may burn your hand.
Fig. 9
The machine's top shelf is a cup warming plate on
which cups are kept heated and ready for use.
This feature is very important to obtain good coffee
as the pre-warmed cups prevent the coffee from
cooling too quickly.
8.1. Preparing coffee
· Unclamp the filter-holder from the dispensing unit
and knock out any grounds into the receptacle
provided for purpose, making sure not to damage
rim of the filter.
· Use the filter for 1 or 2 coffees, according to need.
· Fill the filter with coffee, level it off, and press down
gently with the tamper.
· Remove any ground coffee that clings to the rim
of the filter after tamping.
Proper grinding of coffee beans is of fundamental
importance to producing good coffee. The granular
texture of the fresh grounds should be such that it
takes 25-30 seconds to produce the beverage. If the
coffee grounds are too coarse, the coffee will be pale
in color and weak in flavor, with only a very small
amount of white crema. If the grounds are too fine,
the coffee will be dark with no crema. Good coffee
can only be made if the beans are freshly and
uniformly ground by sharp grinding burrs. Then the
coffee must be measured out into uniform doses of
approximately 6 grams each.
Freshly ground coffee beans are very important
because they quickly lose their aromatic qualities
once they've been ground, and the fats present in
the beans become rancid.
13
8.4 Preparing tea, camomile, etc.
Place the receptacle under the hot water spout and
use the dispensing control according to the model
(Fig.9). When the desired quantity has been obtained
turn off the switch.
Add the beverage desired.
When purified water is used, these beverages often
assume a darker color.
If you would prefer a lighter colored drink, draw fresh
water from an ordinary tap and proceed with the
heating phase as described in point 8.3.
9. ADJUSTMENT AND SETTING OF THE
DOSE (DE model)
It is possible to adjust the dose of coffee and hot
water dispensed by electronically controlled models.
9.1. Adjusting the dose
The quantity of coffee and hot water dispensed can
be adjusted using the button panel or the hot water
controls.
1. Press the E button on any button panel and
hold it down for 8-10 seconds until water stops
flowing from the dispensing unit and the LED of
the continuous flow button on the first button
panel on the left begins flashing.
2. It is necessary to make 1 or 2 trial cups in order
to make adjustments to dispense the correct
amount of coffee in the cup.
3. Put the filter-holder(with ground coffee) on the
left unit and the cup under the spout.
4. Operate the selected button(i.e. button A for
one small cup).
5. Once the required coffee amount in the cup has
been reached, press the stop button A. Coffee
will stop pouring and the microprocessor will
store the dose.
6. Press the continuous button E again. The LED
will go out and the machine will store the new
quantity.
7. Make the coffee and check the cup amount in
order to check that programming is correct.
If some doses have to be changed(A-B-C-D), once
at point 5 repeat the instructions in points 3-4-5 for
each dose, remembering to use the filter-holder with
the appropriate dose filter and freshly ground coffee.
Then carry out point 6 and repeat point 7 to check all
changed doses.
If all units are to be programmed with the same
doses, you are finished. If the dosage of another
group is to be changed, proceed as indicated in the
above mentioned points 1-7, using only the button
panel of the selected group.
Fig. 10
10. MAINTENANCE
10.1. Daily
