unscrew the fixing screw and twist the motor to the right to set free the clips.
In case of total dissambly; pay
attention to the details shown in
the pictures next to this text.
As shown in the pictures, grey inside base must be moved to the motor. If not, the
base will cause friction provoking a break in the motor.
The tool reference 10040130 can be used as a help.
A5. Extractor
Extractor
The steam and vapour that is generated by
the beaters can reach the product
containers and if they become damp they
form lumps in the powder. This
consequently results in the irregular
extraction of the product. To avoid this, the
extractor is used to remove the steam and
vapour from the interior of the machine.
It works on 24 Vdc

A6. Coffee grinder
The M03 One-Touch Drinks model : . Technical Characteristics
Turning the handle anti-clockwise gives a coarser grind and moving it clockwise
gives a finer grind. The grinder used in Rio is regulated by time. Grinder
programming in function 315 (check details in programming manual)
To get the desired amount of coffee for your Service: first adjust the
“grinding point” using the handle. After set a time for the grinder in the function
315 “grinding time”. It is advised to scale the ground coffee in each Service. Last,
adjust the piston washers in the best position (check in section A7. Coffee Group
+Piston).
Turning the handle that adjusts the grinding point will have an effect on
ground coffee granulometry, but also on ground coffee Flow. Remember that
grinder is controlled by time: 3 seconds of coarse coffee will make more
grams than 3 seconds of thin coffee.
It can be said that turning right or left the grinding point handle will vary the amount of
coffee ground for your service. In that case, the grinding time set in function 315
must be modify as well to keep getting the desired amount of coffee for each service.
A7. Espresso Group+Piston/Brewer
Made of resin, it is the element that the machine uses to make the espresso coffee.
The group has moving parts that are activated by a 24 Vdc motor that moves
a crank which moves the coffee from the dosage element to the piston. At the
same time it also moves a lever that activates a micro switch; this indicates the
position of the infusion element to the control board.
Voltage 230 Vac
Nominal power 400 w
Speed 1250 rpm
Diameter of the grinders 63 mm
Grind points 0.026 mm

To remove the espress group from its
anchor position, both white levers must be
turned as indicated in the photograph.
If the group was in the brewing position,
to remove it, it is necessary to remove the
piston first, as indicated a side.
Pull out the clip Remove the piston
To put the group back on the machine, it can be in any position and does not matter that it has
been turned out of the machine. Just put it in its place and fix its two
anchor levers; the engine of the group will position it correctly.

A8.
Tray of liquid residues and coffee cakes deposit
Coffee cakes deposit collects “coffee cakes” coming from
coffee group. It has capacity for 60 cakes. After 60 coffee
services the display will show a message asking to empty
the deposit. If the counter want to be disabled use your laptop
and the Configurator app to modify the settings cmq file.
Tray of liquids collects all the liquid residues that the
machine generates. It has capacity for 1 litre.
Both parts can be removed with the machine lock. Pull the
tray to remove both parts.
A9. Water eposit Container
It has capacity for 4 litres. It is at atmospheric pressure
and temperature. The water is taken from this deposit to
create the espresso coffee and instant beverages.
If you wish to connect the machine to the mains/water
network, there is a separate kit available.
A10. Volumetric counter
Its function is to measure the quantity of water that is
pumped for the creation of the espresso coffee
A blade inside it spins boosted by the water flow. Two
magnets on the blades activate a terminal located on the
counter cap. The three terminals on the cap are positive,
negative (5V cc) and the _П_ (square signal symbol). If it
is measured between negative and _П_ when water is
pumped through the counter it will have gotten the
voltage difference 0V and 5V. In a digital tester it will be
shown 2.5V which indicates that the counter is working
well.

A11. Water pump
This element has the job of pumping water from the cold water deposit to the hot
water boiler. The cold water pushes the hot water towards the EVs for the instant
products or towards the infusion element for making espresso coffee.
When an espresso coffee is created, the water pressure needed is quite high to
be able to pass through the compressed ground coffee in the infusion element.
This resistance the coffee offers makes the water pressure in the boiler increase
up to a pressure of 9 Kg/cm². At this pressure the by-pass opens allowing a
small amount of water to return; sufficient to prevent the water pressure from going
over the 9 Kg/cm².
The by-pass is a small hole covered with a ball that is held in place by a spring.
This spring will hold a pressure of 9 Kg/cm², but over this pressure it
compresses and allows the water to pass.
The pressure of 9 Kg/cm² is considered the ideal for creating espresso coffee.
When the instant beverages are created, there is no resistance offered and so
during there creation the water pump works at lower pressures than when creating
espresso coffees.
Technical characteristics:
Voltage 230 Vdc
Power 48 w
Working pressure 9 Kg/cm²
Maximum pressure 12 Kg/cm²
The pump has an anti return valve that prevents the return of water from the boiler.

A12. Boiler
The boiler works under pressure and has a capacity of 320 cc. It warms up the water
for the creation of the espresso coffee or soluble products.
D1. Electrovalves
D2. Temperature sensor (PTC)
D3. Clixon, rated at 120º C
D4. 1100 W heatting element
D5. upper cover
D6. lower cover
The boiler is made of brass and does not need any device to control the level of
water and it fills automatically from the moment the machine is switched on. After this
water is used it is replaced with water from the fresh water deposit so the boiler is always
full. The BOILER MUST BE EMPTIED IF THE MACHINE WILL BE IN FREEZING
TEMPERATURES SO NOT TO BURST THE BOILER.
There are three outlets; one through a 3-way EV for the creation of espresso coffee. This
EV has an outlet from the boiler, another goes to the infusion element, and the third that,
at rest, allows the infusion element to be at atmospheric pressure.
E1. Solenoid
E2. Valve
E3. 3rd outlet
When the machine is in the process of making espresso coffee, the third is closed while
the outlet from the boiler and the inlet to the infusion element are open to each other.
F1. 3rd outlet closed
F2. To the infusion group
F3. From the boiler
When the machine finishes creating an espresso coffee, the EV goes to rest state
and closes the outlet from the boiler leaving the infusion element open to the third
outlet. In this way the water that did not pass through the coffee and was retained in
the infusion element goes out through the third outlet to the residue bucket.

3. INSTALLATION AN SWITCHING ON
3.1. Installation
The power supply of the machine requires a socket, or another system, that allows its
disconnection. The method used must guarantee the complete disconnection of both
poles. Elemental safety requirements:
a) Never touch any mechanisms with wet hands or feet.
b) Never connect or use the machine barefoot.
c) Never pull on the flex to unplug the machine.
d) Never leave the machine exposed to the elements: sun, rain, snow, etc.
3.2 Water connection
The machine can work with its water deposit of 4 litres (see
point A.14) or connected to the mains city water supply. To
connect the machine to the mains, use a ¾” male
connection. The mains supply must provide drinking water
at a minimum of 5 litres/minute and a pressure of between
0.5 and 10 kg/cm².
Following low voltage safety requirements, the water
connection and the socket must be separated by at least 1
meter.
Mains supply KIT
Depending on the quality of the water, hardness, chlorine, bleach, etc, the connection
should be complemented with a filter.
If the machine is fitted with a filter, the minimum water pressure should be 1.5 Kg/cm².
3.3 Electrical connection
The supply voltage of the machine is indicated in the characteristics plate, there is one
inside the machine and another on the back. Depending on the machine code and
the country, it can operate at 110 or 220 Vac, with a frequency of 50 or 60 Hz. The
installation must have:
•An earthed socket
•A minimum power rating of 2000 w
•The installation site must have a breaker switch and a good ground
connection
