In this section it is possible programme requests for periodic washing. The machine will show on the display a
message such as "WASH GR.1".
There are three types of wash request:
Cappuccino maker wash request.
The set time is counted from the last selection made using milk.
At the end of the set time for cappuccino washing request, the machine will signal this request on the display. All
selections that use milk will be locked until washing is performed. All other selections may still be used.
After a selection is made using milk, if a wash cycle is run (prior to when the set time elapses), and other milk
selections are not made, the machine will no longer require any washing.
For this type of request the minimum interval is 30 minutes, and the recommended reset time is one hour and thirty
minutes.
1.
2- Group wash request.
This request is programmable for each group at intervals of a minimum of one hour and a maximum of 24 hours.
By setting a time between one and 24 hours for the group wash request, the machine will start counting the time
from the moment this option is activated.
When this time interval has elapsed, even if wash cycles have been run, the machine will show this request on the
display until the wash cycle has been performed.
All machine keys remain active even during this indication.
3 - Machine start-up wash request.
When this request is activated, each time the machine is started again after a shutdown of not less than five minutes,
it will show on the display a wash request for group 1 or group 2. The signal will stay on until wash cycles are activated
for both groups.
When several wash requests are activated (cappuccino maker wash, group wash, start-up wash) these
requests may overlap, making it necessary to perform several consecutive wash cycles.

MACHINE COMPONENTS
8.1
Boiler
1
The boiler, made of copper plate, housed the heat exchangers
and the electric heating element (1). The heating element heats the
water in the boiler.
Water to make coffee is taken from the heat exchanger, while hot
water is taken from the boiler. Steam is taken from the upper part
of the boiler.
8.2
Heat exchanger
The heat exchangers (2) (60 mm diameter capacity 445 ml) can heat
the water up to the ideal temperature to make a perfect espresso.
The function of the heat exchanger is the exchange of thermal energy
between the water inside the exchanger it self and the water inside the
boiler.
This component cannot be replaced.
8.3
2
Automatic Water Refill
The AWR system (automatic water refill) is for the control of the boiler
level. It consists of:

a working level probe blue connector (3);

a minimum safety level probe red connector (2);

an electronic level regulator in the electronic control unit;

a hydraulic circuit with a solenoid valve (1) controlled by the control unit.
The level probes act as a pole in the low voltage electrical circuit. When
the level of the water falls, the circuit interrupts itself and the electronic
control unit sends an impulse to the AWR solenoid valve (1) and to the
motor pump which starts the automatic refill with water, while keeping the
level in the boiler constant.
8.4
Volumetric doser
The volumetric doser (5) measures the quantity of water sent to the unit to make
espresso coffee.
It is composed of a rotor with magnet (6) and a Hall-effect head (7).The rotor
generates a magnetic impulse which is sent to the electronic control unit.
This impulse is sensed by the control unit and stored during dose programming.
Each flash of the LED (4) on the volumetric doser indicates that the doser is working
properly (flow of 0.32 cc of water).

8.5
Dispensing unit
The dispensing unit is the “heart” of the coffee-machine. It has a piston
that presses the coffee for infusion and a movable arm acting as stopper. The
piston and the stopper are controlled by a D.C. motor.
The mechanical wear of some components alters the operating conditions
of the inside parts, modifying the machine’s original defaults (see group
adjustment in Chap. 11).
To keep the machine 100% efficient, carry out checks and maintenance
periodically .
We recommend replacing the following components after every 50,000*
cycles:
1 Silicon brush
2 Upper piston OR gasket
3 Mesh filter
5 Bottom shower plate
6 Teflon connecting tubes
7 Silicon connection pipe
After 20,000* cycles (or 3 months' use) we recommend checking and
changing, if necessary, the following components :
4 Lower seal OR gasket
(*) The data indicated for replacement of the components are to be meant as the maximum values that can be
reached and depend on the regularity of service and cleaning as specified in Chap.12.

Maintenance of groups
The delivery group is the main mechanical component of the machine. It requires regular maintenance. This
maintenance requires the group to be removed.
To replace the delivery groups, proceed as follows:
Open the upper cover.
Disconnect the electrical plug located in the outer part of the group.
Disconnect the water delivery tube at the rapid connection.
Disconnect the silicon tube connected to the output of the group head.
Open the grounds drawer, and use a 10 mm spanner to loosen the four bolts that hold the group to the machine
frame.
6. Remove the disconnected group from the top of the machine.

When removing one or both groups, it is not necessary to shut down the machine, bleed the pressure in the boiler
or shut off the incoming water.
In this way, in a machine with two groups, while one group has been removed for replacement or repair, the other
can continue to provide available services
The push button panel for the removed group will automatically be disabled when the electrical plug of the group is
disconnected (point 2).

During maintenance of the group, it is advisable to clean carefully in order to remove all coffee residues from the moving
mechanical parts of the group.
These residues, in the long run, may degrade mechanical operation of the group, eventually leading to malfunction signals
from the machine.
All mechanical parts of the group must be cleaned with warm
water except for the electrical part of the motor, which must be
dealt with only using brushes and dry cloths.
After cleaning, it is recommended to grease some parts of the
delivery group, especially points where mechanical movement
causes the most friction.

8.7
Pressure control (pressure switch)
It is used to turn the heating elements on or off according to the pressure
reached inside the boiler. Pressure regulation can vary from a minimum of
0.5 bar to a maximum of 1.4 bar.
Contacts inside the machine are subject to oxidation. We recommend cleaning them regularly with an antioxidant spray.
Calibrate the pressure switch while the machine is working, regulating pressure with the relative screw on the component (1).
8.8
Anti-flooding device
8.9
Valve unit
By means of the cover on the pressure modulating valve, any water
that comes out of the valve for any reason is collected and sent to the
drainage through a pipe.
Valves are devices that guarantee safety and correct working of the machine.
Pressure limiting valve (safety valve)
The pressure limiting valve guarantees that the pressure inside the boiler does
not exceed 2 bar.
Discharge if the pressostat fails, the valve capacity is such as to discharge all
exceeding pressure from the boiler.
Anti eddy valve
It consists of an expansion valve and an anti-eddy valve.
•
expansion valve: the cold water which the pump sends to the exchangers while
coffee is being dispensed warms up. The heat causes the increase in the volume
of the water. The valve limits the maximum pressure inside the circuit by opening
and letting a few drops of water out, stabilising pressure at 12 bar.
•
anti eddy valve: its function is to prevent water from flowing back from the exchangers to the hydraulic circuit.
Antidepression valve
The function of the antidepression valve is to prevent the return of liquids to the
boiler through the steam nozzle. It also eliminates the cold air from inside the boiler
when the machine is warming up.
8.10 Pump system
This component has to feed the machine by raising water pressure
to 8-9 bar for dispensing coffee and filling up the boiler automatically.

13.9 INTERFACE CONNECTION diagram
Functional Technical Specification 32 I/O relay
Thanks to the interface dosing can be connected to management systems that use for each key the corresponding
output of a relay or of an open-collector transistor.
The I/O card utilises a relay contact.
All relays share the same connection on pins 37-38-39-40 of the output connector CN7.
On this latter, besides the counting outputs, there is the enabling for selections.
The “waiter key” must short circuit the signal of pin 33 with the ground of pin 35.
The signals on the relays have a duration of 500 mSec.
Installation procedure
1)
Connect the I/O card to the dosage with the dedicated serial transmission cable and the 12V power supply
cable, following the enclosed diagram.
2) Programme the coffee doses, inserting the programming key according to the known procedures.
3)
Take the programming key out and verify that selections are locked without the waiter’s key inserted
between pin 33 and pin 35.
The lever switch on the I/O must always be left in the I/O active position
Output correspondence
Key corresponds to the output of a relay.
To better identify them, summarising tables follow giving the connector output with the corresponding selection
push button.
