7.1 How to make coffee
· Detachthelterbasketfromthedispensinggroup.Turnitupside
downandknockdownonthelteredgearea(takingcarenot
todamagethelter)directlyontothecoffeegroundscollector
tray to empty out all the coffee grounds.
· Usethesingledoseordoubledoselter,asrequired.
· Fillupthelterwiththedoseofgroundcoffee,levelthecoffee
out and press in lightly using the appropriate coffee presser.
· Remove any ground coffee remnants possibly still on the edge
ofthelter.
Leaving ground coffee remnants on the edge of the lter
may prevent the seal from closing tightly enough with su-
bsequent loss of water and coffee grounds.
· Hook the lter basket up onto the dispensing group rmly
enough to ensure optimised tightness.
· Position the cups under the dispensing spouts. Start up the
coffee dispensing cycle by pressing in either the key or the
pushbutton, depending on the relative machine version.
· Oncecoffeedispensingiscomplete,leavethelterbasketin
the dispensing until the next dispensing cycle is run.
During the dispensing cycles, beware of the hot machine
parts i.e. particularly the coffee dispensing groups, the
steam spouts and the hot water dispenser pipes. Placing
one’s hands under the dispensing group and spouts during
machine operation is strictly prohibited.
7.2 How to make cappuccino
· Make a dose of coffee in a cappuccino cup.
· Fill a tall, rather narrow container up halfway with milk.
· Position said container under the steam dispenser nozzle so
that the nozzle touches the bottom of the container.
· Open the steam tap and lower the container until the steam
spray skims the surface of the milk.
· Keep moving the container up and down vertically so that the
nozzle simultaneously moves in and out, frothing the milk (to
a creamy foam)
· Close the steam tap and pour the frothy milk into the cappuccino
cup containing the coffee.
Once done, immediately wipe off the steam dispenser nozzle
using a clean, dry cloth. This will avoid milk residue crusts
on the spout.
Warning: the nozzle will be very hot. To avoid skin burn
hazards, avoid touching it directly whilst cleaning.
7.3 How to heat up a drink
· Plunge the steam dispenser nozzle directly into the liquid that
requires heating.
· Open the tap gradually to enable the steam to exit the spout.
This will enable the steam to gradually heat the liquid up to the
required temperature.
· Once the temperature has been reached, close the steam
tap.
Once done, immediately wipe off the steam dispenser nozzle
using a clean, dry cloth.
Warning: the nozzle will be very hot. To avoid skin burn
hazards, avoid touching it directly whilst cleaning.
7.4 How to make teas and infusions
· Position a container under the hot water dispenser pipe and
press the relative pushbutton to start drawing the hot water.
Once the required quantity of hot water has been drawn, press
the pushbutton again to stop drawing.
· Addtherequiredteaavourintothehotwater.
The use of treated water may cause the tea or infusion to
have a darker appearance compared to use of standard
water. If normal tea or infusion colouring is preferred,
proceed with heating up non-treated water as described
under previous section 7.3.
8. DOSAGE ADJUSTMENT AND CALIBRATION
(for versions equipped with this function)
8.1 Electronic dosage machine versions
TheoverallseriesofSoaEspressocoffeemachinesisavailable
in automatic coffee dosage versions (Automatic).
Said dose can be adjusted and customised.
8.1.1 Dosage adjustment
Coffee dose adjustments are carried out by acting on the group
keypads:
· Arrangethelterbasket,eithersingleordoublebasedonthe
key to be adjusted, as described under the “how to make coffee”
section.
· Keep the key (Fig. 8.1 – item 18) pressed in until the relative
LEDashesandtheversionsttedwithadisplayshowupthe
“PROGRAMMING SELECT WITHIN 30s” message
· Theashingledindicatesthatthemachineisintheprogram
-
ming phase. Once 30 seconds have gone by the machine will
automatically revert to operation mode.
· WhilsttheLEDisashing,pressthekeyrelativetothedosage
that must be programmed, to start dispensing.
· During the dispensing cycle, the LED corresponding to the
selected program key will stay on, as will the LED on key (18).
Theversionsttedwithadisplaywillshowupthe“PROGRAM-
MING” message followed by the type of coffee being adjusted
(espresso or “long” diluted (i.e. weaker).
· Wait for the cup dose to reach the required quantity, then press
the key again to stop the dispensing cycle.
· The adjusted quantity is stored by the electronic power pack.
· repeat the operation on the remaining keys. The LEDS relative
to keys that have already been programmed will stay OFF.
For dose adjustments on machines with two or three di-
spensing groups, start the adjustment operations from the
keyboard that is rst to the left on the machine frontlet.
The electronic power pack will automatically store and apply
the adjustments to the other machine keypads.
If adjustment of the groups relative to the second and/or
third keyboard is also required, start the procedure all over
again from the beginning.
