DISPENSING COFFEE
• Place a cup/demitasse under the group’s dispensing spout.
• Press the desired dose button, e.g.
and wait for the
coffee to be dispensed (LED will switch on).
• To stop the coffee dispensing ahead of time, press the
or button.
Should an anomaly occur or the pushbutton
panel freeze, use the manual switch (see the
"AEP" version).
PROGRAMMING THE COFFEE
Each dose must be programmed with freshly
ground coffee and not with previously-used cof-
fee grounds.
The machine is programmed by default. Should the coffee
dosesneedtobemodied,proceedasfollows:
• Always programme the pushbutton panel of the right-
mostgrouprst.Thisway,allthepushbuttonpanelswill
be automatically programmed. If necessary, subsequently
programme the others.
• Place a cup/demitasse under the group’s dispensing spout.
• Press the
button for at least 5 seconds, until all the
dose button LEDs are lit.
• Press the dose button that you would like to programme,
e.g.  (the button will ash whilst it is being pro-
grammed).
• Toconrmthedose,pressthe button again or the
button.
• If desired, repeat this operation for the other dose but-
tons.
• When the programming is complete, press the
but-
ton until all of the LEDs on the pushbutton panel go off.
All the groups will now be programmed this
way. Should you wish to programme them dif-
ferently, proceed to singularly programme the
left-hand groups one by one as illustrated above.
6.9 Dispensing steam
The steam dispensing method is different for each machine
type;therefore,the instructionsspecic to themodel being
used must be followed.
To optimally froth the milk, follow these simple rules:
• Heat only the amount of milk you intend to use; once
heated, it will have to be completely poured from the jug
and not heated again.
• Froththemilkwhichshouldbeatatemperatureofaround
4°C.
In any case, before proceeding to dispense steam, the following
precautions must always be followed.
Carefully move the steam nozzle using the spe-
cic anti-scald rubber grip (1).
Do not direct the steam towards hands or other
parts of the body. Do not touch the steam nozzles with
bare hands; use the appropriate PPE.

Before using the steam nozzle, the condensa-
tion draining operation must always be carried
out for at least 2 seconds.
To keep the steam nozzle tips in perfect working
order, it is advisable to carry out a brief dry dis-
pensing run after each use. Keep the tips clean
at all times using a cloth dampened in lukewarm water.
Only leave the steam wand immersed in the milk for the
time needed to heat it.
Do not open the steam valve with the steam
wand immersed in milk and the machine
switched off, as the latter would suck milk into
the pipes.
