HOT WATER DISPENSING
The machine has one hot water valve equipped with a swivel wand which allows the use
of large water containers and guaranteeing good general ergonomics.
The valve, marked with the symbols is operated by a joy-stick with movement in
any direction.
Water is taken from the same boiler used to heat the coffee water and to produce steam.
CONTROL OF WATER LEVEL IN THE BOILER
This is done by means of a level probe and of a solenoid valve what control the water
level in the boiler, topping it up automatically when required.
CONTROL OF WATER TEMPERATURE IN THE BOILER
Water temperature in the boiler is controlled by a sensor that switches the heating
elements through a remotely controlled power switch.
The temperature value is settable from 112.5°C to 128.3°C, standard factory value
122.5°C.
Consequently, it also controls the pressure in the boiler, kept from 0.6 bar to 1.6 bar,
standard factory value 1.2 bar.
Consequently, it determines also the temperature of the coffee infusion water.
STEAM DISPENSING
The machine has one or two steam valves equipped with swivel wands which allows the
use of large milk containers and guaranteeing good general ergonomics.
The valves, marked with the symbols are operated by a joy-stick with movement
in any direction.
The steam is produced by the same boiler used to heat the coffee water.
DESCRIPTION OF THE APPLIANCE
The main functions of the machine, and its relative parts, are described below, with a view to
ensuring its maximum performance.
USER-MACHINE INTERFACE
The machine has an alphanumeric display which allows communications between the user
and the same machine, in a specific selected language.
The inputs to the machine are executed by means of:
- Programming key
- Increasing pushbutton +
- Decreasing pushbutton –
- “Enter” pushbutton
Communication is obtained by means of a series of writing that may be fixed or scrolling if
long: wait and read the complete written message to ensure you fully understand the alert.
COFFEE DISPENSING
Independent dispensing groups with programmed or manual coffee doses.
Each dispensing group has a heating circuit for brewing water working with an heat
exchanger coupled to a boiler with the following capacity:
- KUP 2gr 12 liters
- KUP 3gr 16 liters
This circuit ensures that the dispensing group remains at a constant and optimal
temperature even when it is not being used, thanks to the effect of the natural circulation
of hot water flowing through the circuit itself.
The boiler water temperature setting determines consequently the brewing water
temperature.
Values from 72°C to 90°C about.
The machine is equipped with the following filter baskets for the coffee powder:
- 7 grams
- 9 grams (Optional)
- 17 grams
- 21 grams (Optional, with relevant filterholder)

1514
PROTECTING THE HEATING ELEMENTS
The three boiler heating elements, 1170 W each for the 2 groups models and 1840 W each for
the 3 groups, are protected from overheating.
Such protection is obtained by means of a thermostat with manual reloading which controls
the cutting off of power to the heating elements.
In each of following cases:
- Excessive duration of heating,
- Exceeding of maximum allowable temperature value,
the heating elements are disabled and a major fault is displayed.
10
WARMING THE CUPS
These models are equipped with cup heater trays with the capacity to contain a large
number of cups on various levels and to keep them warm in order to guarantee an excellent
cup of coffee.
The heat is generated by a natural flow of hot air from the inside of the machine.
11
MEASURING THE BREWING PRESSURE
The appliance is fitted with a pressure sensor that measures the pressure delivered by the
pump during brewing.
Through the reading of the display, this enables technician to set manually the pump
pressure during coffee dispensing.
8
MEASURING THE WATER SUPPLY PRESSURE
The same sensor referred to in the previous paragraph measures, when the water pump is
stopped, the water supply pressure with which the appliance is fed.
Value displayed on the same display.

USER ALERTS
The machine can display the user the following alerts:
“ WAIT: MACHINE IS HEATING UP ”
“ MACHINE READY ”
“ MACHINE IN SLEEP MODE - NIGHT CYCLE ”
the following minor alarms:
“ BREWING NOT SATISFACTORY- CHECK COFFEE TAMPING OR DOSING OR GRINDING ”
“ BUFFER BATTERY ABOUT TO GO FLAT- REPLACE PROMPTLY ”
the following major alarms:
“ BOILER WATER LEVEL CONTROL SYSTEM FAULT - MACHINE OFF - REPAIR ”
“ BREWING WATER TEMPERATURE CONTROL SYSTEM FAULT - MACHINE OFF - REPAIR ”
SOUND EMISSION
The weighted sound emission level A of these models is 80dB uncertainty 1dB.
12
13
CONTROL OF COFFEE DOSAGE
Each group head is fitted with a flow rate sensor, or a volumetric dosage device.
It measures the volume of water being fed through the group, to ensure that the final volume
of coffee in the cup corresponds to the value programmed by the user.
At the end, the final volume of coffee in the cup, in cubic centimetres (millilitres), corresponds
to its weight in grams, since the specific weight of the extract being almost the same of the
water.
To achieve this result, the device control system takes account of the quantity of water neces-
sary to wet the coffee puck, quantity that does not reach the cup during the extraction, and
adds it to the programmed quantity.
The quantity of water necessary to wet the coffee puck is presetted at the factory, with the
quantity of ground coffee as 6/8 grams for singles and 12/16 grams for doubles.
The dispensing capacity corresponding to these parameters is around 1 cc/second, ie
obtained by grinding granulometry required for the Italian espresso.
When using different quantities of coffee or different grinding granulometry, kindly contact
Technical Support.
This system is not requiring complex and unreliable technologies such as Gravimetric
technology, while still allowing a very high precision in determining the so-called Brew Ratio
but with very low production times: for example, is not requiring the filterholder weighing
before and after loading the coffee.

USE OF THE WORKING AREAS
The machine is divided into a coffee dispensing area on the right and a steam and hot
water dispensing area on the left.
It is thus possible to work with containers of up to 70 mm (2.76 inches) in height or up
to 130 mm (5.71 inches) in height, depending on the heights of the work counters used
(dispensing groups) and with containers of up to 150 mm (5.91 inches) in height (water
and steam wands).
Positioning the coffee grinder on the right of the machine speeds up the serving of
coffee, given its proximity to the dispensing groups.
This subdivision ensures that two operators can use the machine at the same time,
without obstructing one another-one serving teas and cappuccinos and the other serving
coffee.
Includes two independent grilles and a raised work counter for coffee area.

In order to froth up the milk, which is essential for preparing cappuccino, half-fill a tall,
narrow container with milk and proceed as follows:
1) Briefly open the steam valve using he joy-stick marked with the symbol as so to
remove any water condensation that might have collected.
2) Place the container with the milk underneath the steam wand so that the spray nozzle
touches the bottom, then reopen the steam valve and bring the milk to the desired
temperature.
3) Lower the container so that the spray nozzle rises almost to the surface of the milk and,
from this position, raise and lower the container repeatedly so that the spray nozzle
enters and surfaces from the milk alternately.
Continue until the milk has frothed up, afterthat close the steam valve.
To make the cappuccino add hot espresso coffee to the hot frothy milk.
MAKING TEA – CAMOMILE TEA ETC
Put the container under the hot water nozzle and activate the hot water dispenser by using
the joy-stick marked with the symbol .
Once the set hot water volume is reached close the hot water valve.

COFFEE DISPENSING WITH MANUAL DOSING
This allows coffee of different lengths to be dispensed each time by pressing the button
marked and repressing the same button when the desired dose has been
dispensed.
This function is enabled at all times, irrespective of the machine status - even in the case
of a major fault - so as to enable washing or checks during repair operations.
COFFEE DISPENSING WITH AUTOMATIC DOSING
Allows the dispensing of coffee in preset doses.
This is carried out by pressing the buttons marked with the coffee cups symbols once only.
Dispensing stops automatically once the preset dose has been dispensed.
This function is only enabled when all the envisaged operating and protection conditions
have been met and can normally be stopped manually.
During the dispensing the time (s) elapsed from the dispensing start and the dosage of the
coffee (cc) are displayed.
The final value of the time taken, together with the coffee volume value, is visualized for 10
seconds after the end of the dispensing.
The value of the time taken, together with the one of the final coffee volume, allows to
assess whether the grinding grade of the powder used is correct.
See the following paragraph.
6
7
MAKING THE COFFEE
Factors of basic importance to make good quality coffee are:
- Use of recently ground fresh coffee, because it rapidly loses its aroma and the fats
contained turn rancid.
- Grinding of uniform size, which can be obtained only with good quality and well
maintained coffee grinders. The uniform size of the powder ensures a complete
extraction and a good reproducibility of the result in the cup.
- Use of properly warmed cups, which contribute considerably to preserving the cream of
the infusion.
With the exception of the above-illustrated factors, there are many recipes to obtain many
different types of infusions, based first of all on the type of coffee bean used, both for the
production of mixes and as single-origin coffee.
The fundamental parameters are:
- Type of coffee bean used
- Grinding grade
- Quantity of powder used
- Infusion water temperature
- Infusion pressure
For example, in order to obtain a good Italian-style espresso coffee, grinding must allow
the espresso to be dispensed in approx. 25 seconds and to have, on average, a volume
equivalent to approx. 25 cc.
The quantity of ground coffee must be of around 7 grams

2322
WEEKLY CLEANING OF THE DRIP TRAY
At least once a week remove the lower cup grille, remove the drip tray and clean it.
Check and clean the drain box too, removing any dregs with the aid of a teaspoon, and
then rinse it .
WEEKLY CLEANING OF THE BODY
Simply use a damp (non abrasive) cloth.
Do not use alcohol or solvents to clean written or painted parts as this could damage them.
MAINTENANCE AND CLEANINGB
DAILY CLEANING OF THE GROUPS AND FILTERHOLDERS
Each evening or at least once a day, clean the group shower and the filterholder gaskets with
a cloth or a sponge.
Rinse the filters and filterholders in boiling water in order to remove the fatty deposits of the
coffee. It is advisable to wash the inside of the filterholders and filters with a view to avoiding
incrustations and coffee deposits which could fall off during coffee making, forming grounds in
the cup.
DAILY CLEANING OF THE STEAM WANDS
The steam wands, used for heating drinks, must be cleaned immediately after use in
order to safeguard against the formation of incrustations that could block the holes of the
spray nozzle and also to ensure that the residue of previously heated drinks does not
deteriorate, leading to the unhygienic formation of bacteria .
Externally clean with a moist sponge, the steam nozzle immediately after every milk
preparation cycle.
To clean the inside of the wand instead proceed as follows:
1) Fill a stainless steel pitcher with cold water up to at least the same level as the milk resi
duals on the wand.
2) Place the wand into the water filled pitcher.
3) Operate the steam valve by means of the joy-stick marked by symbol until the water
boils, obtaining a complete disinfection of the wand.
WEEKLY CLEANING OF THE GROUPS
At least weekly, it is necessary clean the dispensing groups from coffee deposits with
an internal cleaning through a semi-automatic procedure guided by the machine .
That procedure is to be started only with hot machine ready to use and for all the groups,
as follows:
1) Press twice in quick succession the “ENTER” button”: the machine automatically enters a
state of partial operation suitable for programming.
2) The main menu appear on the display: press any of the coffee buttons marked with the
“+” sign to scroll the menu and reach the desired topic, i.e:
“ GROUP 1 CLEANING “ or
“ GROUP 2 CLEANING “ or
“ GROUP 3 CLEANING “
3) Press the “ENTER” button to confirm the chosen option and to start the cleaning
procedure, displaying the following alert:
“ INSTALL THE BLIND FILTER, PUT THE DETERGENT AND PRESS “ ENTER ”
The cleaning starts on the groups, running 10 dispensing loops of 20 seconds each one.
At the end of washing cycle is displayed the following alert:
“ CLEANING FINISHED: REMOVE THE FILTER HOLDER AND PRESS “ENTER” TO MAKE RINSING ”
a rinsing step will get started on the dispensing groups, divided into 30 seconds of
dispensing, 30 seconds of stop and 30 second of dispensing.
On rinse completion remove the blind filter, place the standard filter back and hook the
filterholder on the dispensing group.
4) Quit from programming by scrolling the menu pushing the “+” button until the
following alert is displayed:
“ TO QUIT PRESS “ENTER”, TO REPEAT PRESS “+”
press the “ENTER” button: the machine automatically resumes full operation.

4WEEKLY CLEANING OF THE FILTERS AND FILTERHOLDERS
1) Place three teaspoons of detergent for coffee machines and approx. one litre of
boiling water in a heat-resistant container.
2) Immerse the filters and filterholders in the solution prepared and allow them to soak
for about 20/30 minutes (do not fully immerse filterholders with wood handles:
the water and detergent solution would damage the handles).
3) Rinse thoroughly under running water.

MONTHLY BOILER WATER CHANGING
Due to the fact that the boiler water is used also for the hot drinks, it is preferably to chan-
ge it completely , to clean the boiler inside, minimum once a month.
1) When the machine has heated up, i.e. displaying the following alert:
“ MACHINE READY ”
switch it off by pressing the button marked with the symbol .
2) Operate the hot water valve by using the joy-stick marked with the symbol ,
after having placed a big pitcher underneath the water wand, and take off hot water
from the boiler.
3) Continue to take off the water until it will finish, until it does not more come out of the
wand.

TROUBLESHOOTINGC
BOILER WARNING: WATER LEVEL CONTROL ALARM, FAULT
If the following alert appears:
“ WATER LEVEL CONTROL SYSTEM FAULT - MACHINE OFF - REPAIR ”
the fault could be due to:
1) Water supply stoppage: restore it
2) Fault in the boiler water inlet solenoid valve or obstruction to the passing of water
through some parts of the machine
3) Electrically insulating incrustations on the level probe or an interruption in its
electrical connection that prevents the presence of water in the boiler from being
detected:
Switch off the machine and contact Technical Assistance .
5
4
WATER COMES OUT OF THE STEAM WAND
This means that the boiler is completely full of water instead of containing a certain quantity
of steam.
The possible causes of this are:
- Fault in the boiler water inlet solenoid valve.
- Electrically insulating incrustation on the level probe or interruption in its electrical
connection.
Switch off the machine, turn off the water supply and contact Technical Assistance .

BREWING WATER TEMPERATURE CONTROL SYSTEM ALARM, FAULT
If the following alert appears:
“ BREWING WATER TEMPERATURE CONTROL SYSTEM FAULT - MACHINE OFF - REPAIR ”
a major fault has occurred.
Switch off the machine and contact Technical Assistance .
ALARM: BUFFER BATTERY ABOUT TO GO FLAT
The electronic control unit is equipped with a buffer battery that ensures the storing of the
time and date.
The system continually controls the efficiency of the battery, warning in advance when it is
about to go flat and advising its replacement.
When displaying the following alert:
“ BUFFER BATTERY ABOUT TO GO FLAT- REPLACE PROMPTLY ”
Contact Technical Assistance.
NOT SATISFACTORY BREWING ALARM
If, after dispensing selected with an automatic button, e.g. group 1 single short coffee, the
following alert is displayed:
“ BREWING NOT SATISFACTORY- CHECK COFFEE TAMPING OR DOSING OR GRINDING ”
the coffee may not have been made according to Italian espresso standards, and therefore
adjustments in tamping, dosing or grinding of the coffee powder are required.
Perhaps even adjustments to temperature or brewing pressure are required (also consult
chapters “C - ADJUSTMENTS”, paragraphs 1.5, 2).
Alternatively, there might be a fault due to:
- Water supply stoppage: restore it
- Fault or obstruction to the passing of water through some parts of the machine:
contact Technical Assistance.
THE MACHINE DOES NOT HEAT UP
Due to the (even temporary) lack of water in the boiler the heating element safety device
may have been disactivated.
The heating element safety device can be manually reactivated, after the reason for the
lack of water in the boiler has been eliminated or repaired .
Contact Technical Assistance.
STEAM DOES NOT COME OUT OF THE WANDS WHEN THE MACHINE
IS HOT
This problem normally arises after the machine has been switched on from cold and is
due to the sticking of the vacuum break valve of the boiler; this does not negatively affect
the use of the machine, in fact:
- After venting all the air through a steam valve, wait until the machine heats up
normally and use it.
In the meantime, contact Technical Assistance.

- Coffee ground too finely: adjust it
- Water supply stoppage: restore it
- Fault or obstruction to the passing of water through some parts of the machine: contact
Technical Assistance
8
ONE DISPENSING GROUP DOES NOT HEAT SUFFICIENTLY
There is a reduction to the flowing of the brewing water, e.g:
- Group natural heating circuit clogged with scale deposits.
Contact Technical Assistance
BREWING PRESSURE GROUP DOES NOT HEAT SUFFICIENTLY
Unless this value exceeds 1.2 MPa (12 Bar), in which case switch off the machine and
contact Technical Assistance, this is a fault that does not negatively affect the use of the
machine.
The most likely causes are that the pump is out of calibration or worn.
Contact Technical Assistance.

THE DRIP TRAY IS FULL AND OVERFLOWING WITH WATER
1) Clean the drain box and use a metal wire to free the drain pipe of residue.
2) Eliminate any sagging or strangling of the flexible drain pipe, ensuring that it is always
angled downwards in a straight and even manner.
3) If the above-mentioned causes are not responsible for the fault, this means that there is
a blockage in the drain pipes external to the machine: contact a plumber.
Also consult chapter “B - INSTALLATION”, paragraph 3.
