10. BEVERAGES DELIVERY DESCRIPTION
ADVICES OF USE:
- Always use heated cups: if this is cold, the abrupt temperature change of the espresso coffee will change its taste.
- Never load the filter holder without making an immediate delivery; the ground coffee would "burn" in the group and the espresso ob-
tained would be very bitter.
- The machine's operating process forces the water over the coffee at high pressure. If contact between the water and the ground cof-
fee lasts more than 20/30 seconds, the coffee will taste unpleasant and bitter. This effect is called over-extraction.
- Ground coffee dose, for ONE espresso, between 6 and 7 g. inclusive.
- Checking the wear of the dosing grinder's grindstones.
10.A. COFFEE DELIVERY - DIGIT VERSION
1) Remove the filter holder from the group (A) and dispose of the grounds by hitting the
edge of the filter holder against the bar in the apposite drawer.
Do not hit the filter holder against an unprotected surface; the filter holder's seal could be
damaged. A smart blow should be enough. The small quantity of powder remaining will
not have a negative effect on the taste of the coffee.
2) Fill the filter holder with finely ground coffee, placing the filter holder in the housing pro-
vided at the bottom of the grinder-doser and pulling the lever once for a single coffee and
twice for a double dose.
Attention: always remember to pull the lever to its full extent; then let it return to its rest
position on its own. Always ensure that there is enough ground coffee for at least one
dose in the grinder-doser's reservoir.
3) When the filter holder is filled, press down the ground coffee with the special tamp,
pushing the filter holder upwards.
Clean the edge of the filter holder with the palm of the hand to get rid of excess coffee
powder. This will ensure that the seal between the filter holder and the machine will be
perfect.
If a filter for mixed use is being utilized, you can put a coffee pod instead of ground coffee
in it.
4) Fit filter holder to the machine group, fixing it and turning it until it is fully in. Do not
tighten too much, otherwise it will be difficult to remove after delivery.
5) After having fitted the filter holder properly put a previously heated cup under the spout.
Two cups are required if a double filter holder is used.
6) Press the coffee key on the touch key pad (*).
(*) CONTINUOUS DELIVERY:
Follow the instructions to the points 1)÷5) and press CONT key (1).
When the desired quantity is reached press STOP key (4).
Attention: if delivery is not stopped manually using the STOP key within the time limit of
120 sec., the group will block without any signal. To restart the machine power must be
removed for at least 5 sec. and then restored.
10.B. COFFEE DELIVERY - P VERSION

again to stop it.
10.C. HOW TO MAKE CAPPUCCINO
For making a "professional" cappuccino, fresh milk (±4°C) must be "frothed" to give a foam which will be poured over the
espresso coffee previously delivered.
1 - Switch the steam on for 1 or 2 seconds to clean away milk residues from the pipe.
2 - For heating use a metallic jug, or in ceramics, filled at least for half with milk.
3 - Approach the jug to the steam pipe so as to immerse the spout in the milk for ~ 1-2 cm.; don't put the pipe to the cen-
ter or directly to contact with the jug.
4 - Push the steam button: when programmed temperature is reached, the steam automatically finishes (to set the tem-
perature, see cap. ADJUSTMENT).
5 - If manual steam is used, slowly open the steam tap and move the jug in a circular fashion until the milk starts to froth.
Then quickly close the steam.
6 - Remove the jug from the pipe and pour the frothed milk over the espresso coffee.
MODEL WITH MILK FROTHING DEVICE (OPTIONAL): introduce the milk aspiring pipe in a pitcher containing fresh milk (max. tem-
perature +4°C), then place a cup with 1 dose of espresso coffee under the milk frothing device: press the relevant switch button and
wait until the requested quantity of frothed milk has been reached in the cup. Press again switch button to stop delivery and serve bev-
erage.
