next to this text.
As shown in the pictures, grey inside base must be moved to the motor. If not, the base will be
in 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. T
o 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
It’s the M03 Azkoyen model. Technical characteristics:
Turning the handle anticlockwise gives a coarser grind and moving it clockwise gives a finer
grind. The grinder used in Vitro s1 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. Reme
mber 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 group from its position
of anchor, both must be turned
levers that fix it to its support, such
as indicated in the photograph. If the group
was in
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 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
It has capacity for 4 litres. It is at atmospheric pressure and
temperature. From this deposit is taken the water to elaborate 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 elaboration of the espresso coffee
A blade inside it spins boosted by the water flow. Two magnets
on the blades activate a terminal locate 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 be
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 elaborated, 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 elaborating espresso coffee.
When the instant beverages are elaborated, there is no resistance offered and so during there
elaboration the water pump works at lower pressures than when elaborating 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.

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 as the
boiler fills automatically from the moment the machine is switched on. After this the water that
is used is replaced with water from the cold deposit so the boiler is always full.
There are three outlets; one through a 3-way EV for the elaboration 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 espresso coffee making process, 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 elaborating 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
Mains supply KIT
The machine can work with its water deposit of 4 litres (see point
A.14) or connected to the mains. 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 metre.
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
