4.3.1 Installation fineness of grinding
The coffee beans are crushed using the coffee grinder, which is located underneath the coffee bean
container. When you select a drink, which uses coffee beans, the beans fall into the coffee grinder, where
they are ground using the built-in choppers, going further into the dosing apparatus, which is located in
front of the coffee grinder. From here the coffee is fed into the espresso group.
Fig.4.5
1
If the level of grinding will be too low (very small particles),
the coffee grinder will not be able to ground sufficient amount of
coffee, which would lead to “Grinder” error and will block the dispensing of coffee. In such case you should increase the level of
grinding. For the purpose you must loosen the upper disk by turning it counter clockwise.
If the particle size is large the coffee will be less concentrated (less saturated). The time of working of coffee grinder will be
around 3-4 seconds. The thickness of output jet will be 3-4mm.
in this case you can also cause the leaking of the coffee group,
because very large particles of coffee damage the gasket of the
piston. In such cases you should decrease the particle size – turn
the upper disk clockwise.
The optimum time of grinder functioning is: 5-6 seconds
if coffee dosage is set to position 3 and 6-7 seconds if the
coffee dosage is set to position 4 (see the next section).
2

The quality of grinding of coffee depends on the rotation of the screw, located on the coffee grinder (see
fig.4.5 and 4.6 position1). Turn the screw clockwise grind more (smaller particles) or counter clockwise to grind less (larger particles) – (see fig.4.5).
Set up the grinding of the coffee grinder.
After setting the grinding quality, check the quality of coffee. If needed please set again to achieve the
required level of grinding.
Note: The smaller the particle size the longer will be the extract and the drink will be more saturated.
Setting the grinding parameters for the first time:
Turn the regulatory screw clockwise and bring the blades as close as possible (turn all the way). Then
turning the screw counter clockwise loosen the upper disk by 540-630 degrees (one and a half turn or one
and a half + quarter turn).
For more detailed settings of coffee grinder you can carry out the following actions I the given sequence:
change the position of the regulatory screw (to change the position of the upper disk of the coffee grinder
to a certain angle) and then make a drink and taste it. Version 1.1 / December 2017

PLEASE NOTE THAT CHANGES IN LEVEL OF GRINDING AND TASTE ARE NOT NOTICED RIGHT
AWAY. ONLY AFTER 3 CYCLES YOU CAN FEEL THE DIFFERENCE (after changing the grinding
parameters, discard two drinks and taste the third one to feel the differer.
It is highly recommended to change grinding parameters discreetly, turning the coffee grinder’s disk by
10-20 degrees each time.
The ground coffee is fed into the dosing apparatus, which accumulates ground coffee up to a certain level. When the level is
reached the electromagnetic valve opens and the accumulated
dose of coffee is sent to the espresso group.
The dosing apparatus helps you set the required amount of coffee for the espresso group according to the desired drink. The volume of coffee is regulated with the help of the dosing apparatus’s
cam (see fig.4.6 pos.2 and fig.4.7). The positions can be from 1
to 6 (MAXIMUM). At the same time it is prohibited to set the cam
to positions 5 or 6 without increasing the volume of the boiling
chamber (see further)! THIS CAN DAMAGE THE ESPRESSO
GROUP!
Fig.4.7
It is STRICTLY PROHIBITED to set the cam to positions 7 or higher!
The recommended settings for the cam are positions 3 or 4. This means a dose of 6.5-7.5 grams
per portion (per drink).
The weight of the ground coffee inside the dosing apparatus depends on the quality of grinding and type
of coffee.
After each re-setting of dosing apparatus, please weigh the amount of ground coffee according to the
current manual.
Depending on the weight of the coffee, you might need to regulate (adjust) the volume of espresso
group’s chamber

Milk foam adjustment
To adjust the milk foam on the vending machine do the following:
-
Make sure that the milk container is installed in the refrigerator near the vending machine.
-
Make sure that the milk is fresh and unspoiled.
-
Make sure that the silicone milk supply tube at the vending machine inlet is not pinched.
- Make sure that the vending machine milk system was washed beforehand, and all its parts including the cappuccinatore are clean. Inspect the tubes for any sour or coagulated milk.
Make sure that all the above items are observed and proceed to the milk foam adjustment by sequentially executing the following operations:
-
Open the vending machine door;
-
Insert the service key into the door trip;
- Switch the vending machine on (see the manual) and wait for the boiler to heat up to the temperature specified in settings. To achieve the optimum foam performance the steam boiler temperature
should be set to 130°С;
- Adjust the foam control knob to the middle position (fig. 4.8). For doing this turn the control knob
all the way to the left and then all the way to the right. Set the control knob approximately to the middle
position;

User manual for NERO TOUCH, NERO TOUCH INSTANT
- Select a drink with the addition of fresh milk. As the drink is made, observe the milk flow from the
cappuccinatore adapter. The flow should be uniform, without any "pulsations" or "jerks" (the foam should
be poured into a cup in the form of a smooth stream without any splashes or inflating bubbles).
- Observe the cappuccinatore adapter - it's manufactured of transparent plastic to facilitate its contamination level inspection and adjustment process.
Fig.4.9
- At the cappuccinatore and the adapter joint there's a gap (see fig. 4.9). The foam shouldn't run out
of the adapter during the operation.
- If there's no foam coming out, but a slightly foamed milk, turn the foam control knob counter-clockwise. By doing this you are slightly opening the air delivery tap, and the milk foam should start coming out.
- If the foam is squirting out from the above-mentioned gap, this means that there's too much air
supplied. Turn the control knob clockwise.
The optimal foam adjustment:
The foam is streamed out uniformly and without any pulsations. The foam doesn’t overflow outside the cappuccinatore adapter and should have a fine-porous structure.
When lowering a stirrer to a cup it stands in the foam without declining (the height of the foam
should be higher than the middle of the stirrer).
If having trouble adjusting the foam in accordance with the above instruction, proceed to the following
section: “Offsetting the range of adjustments on the air fine tuning valve” (see below).

Fill the container with milk, taking into consideration the maximum capacity of the container.
To avoid problems associated with milk dispensing locate the milk container level with the vending machine and make sure that the milk supply tube lies on the bottom of the container and has no kinks.
For milk storage, the manufacturer recommends using the special milk cooling module (cooler) that was
compatibility tested with the standards of the countries, where the NERO vending machine or its modifications are going to be used.
The manufacturer can supply the recommended cooling module complete with the vending machine on
demand.
The correspondence of the recommended special cooling module with the standards should be confirmed by the module manufacturer.
5.6 Waste container
The liquid waste container is situated in the lower left part of the machine. You must drop the float into
this container. The given float acts as the sensor indicating the container’s level of filling.
Except for the liquid waste, which is produced during the preparation of drinks, the process of making
coffee from coffee beans, we also have hard waste in the shape of pressed ground coffee, which the espresso group throws out into the waste container, situated in the lower left side of the machine. The quantity of waste is monitored programmatically.
When the software counter reaches the maximum number of drinks (set in the technician menu (equipment) - Errors section - Coffee waste number setting), made using the coffee beans, such drinks become
inaccessible. To set the counter to zero:
• Open the vending machine door;
• Insert the service key into the door trip (see section 2.2);
• Turn on the vending machine (if it’s turned off);
• Remove the coffee waste container (for solid wastes) and remove the wastes;
• 10 seconds after inserting the container back into the vending machine;
• Remove the service key and close the door.
5.7 Autonomous operations kit
In its standard configuration the vending machine is configured to use water from the canister/bottle,
which is installed near the machine.
For water supply connection we have a silicone water pipe, which comes with the package (see fig.4.2

The water for the preparation of drinks is supplied by the following group of
devices: boiler, which heats the water; boiler pump, which pumps the water
into the hydraulic circuit; float chamber, which helps avoid air bubbles and
blocks from entering the hydraulic system.
Flot chamber
The float chamber (see fig.5.9) retains the minimum required quantity of
water, which is necessary to keep the hydraulic system alive and to ensure the
dispensing of drinks, in case the water supply runs dry.
3
Equipped with a sensor it determines the state of the chamber: filled or
empty. During the functioning of the internal pump, the water level gradually
falls inside the float chamber until reaching the set level, where the sensor
reads as if the chamber is empty. At this moment the water from external
source (the valve is opened) or internal source (the autonomous mode pump
4
turns ON) starts filling the float chamber, until the water level sensor deterFig.5.9
mines that the chamber was full. This also forms a permanent water lock. In
case of shut down of external water supply or depletion of water in the internal
source, the float chamber will not be filled within the set time interval, which
will cause the vending machine to be blocked.

on top of the boiler (see fig.5.11), according to the selection the hot water flows:
1. into espresso group, one of the two mixers, directly into drink disposal nozzle (not-INSTANT).
2. into one of the three mixers, directly to the drink disposal nozzle (INSTANT).
It is strictly prohibited to use water, which does not conform to the given standards of
hardness and calcium content (see the vending machine’s technical features). This can
cause rapid deterioration and failure of the machine’s electromagnetic valves!

The boiler and steam boiler surface may be hot.
Before any maintenance works cool down and drain water from the boiler.
Steam boiler (FRESH MILK option)
The steam boiler is installed in the vending machines with FRESH MILK option only. It’s intended for
heating the water to make steam, which is needed for milk foaming.
The steam boiler is installed in the rear hydraulic unit compartment of the vending machine (see fig.
5.11). To access the steam boiler remove the vending machine case rear wall.
To avoid injuries associated with “accidental release of stored energy” and/or “steam burning effect”,
the steam boiler has hardware protection from the pressure, exceeding the working pressure maximum
range. The excess steam, heated by the boiler, is rejected to the liquid wastes container via the emergency valve located at the steam boiler case.
The boiler has nonseparable structure. In the case of boiler breakage and/or the internal fuse blowing
the boiler should be completely replaced. After the boiler replacement, the boiler sensor gaskets and fittings should be visually inspected. This operation is conducted to prevent emergency situations, caused
by bad boiler repair.

To make the process more interactive or visible, the drink disposal section is fitted with an LED board,
which changes its colour, depending on the process underway inside the machine:
• Blue colour - the drink was prepared;
• Red colour - the drink is prepared.
After the drink preparation process is completed the colour of the LED light changes from red to blue and
a single audio signal is given.
The drink preparation and disposal operation comprises of the following steps (see below).
7.1 Placement of the cup
Before choosing a drink place the cup into the compartment for giving out drinks. Then select the image of
the drink on the touch screen.
For small cups, the special folding height adjustable shelf is provided in the compartment (see fig. 5.1 pos. 7).
To avoid spilling over of the drink, into the disposal area tray, please make sure to place the cup
in the disposal tray before selecting the drink!

7.2 Preparation of drinks
Instant drinks
These drinks are prepared by continuously mixing the instant ingredient (powder) with hot water and
then mixing various mixed ingredients in accordance with the drinks recipe, which is set using the vending
machine’s service menu.
To make the drink the water is pumped into the float chamber, from where it goes into the boiler, until it
is filled. The boiler heats the water and maintains it at the temperature level set in the vending machine’s
configurations.
The required quantity of the ingredient is poured out of the container into the mixer. The quantity of the
ingredient is set in accordance with the selected drinks recipe.
Opening one of the valves of the boiler the hot water is supplied to the required mixer, which is located
near the container with the required ingredient.
When the water flows into the mixer, the ingredient is solved into the amount of water set in the recipe.
Water and the ingredient are mixed inside the mixer until the required drink is obtained. From the mixer
the drink flows through the dispensing nozzle into the cup.
Coffee bean drinks
Coffee beans go from the coffee bean container into the coffee grinder, where they are ground and fed into
the dosing apparatus (if the dosing apparatus will not be filled within 10 seconds the vending machine will automatically block the dispensing of ground coffee drinks).
The dosing apparatus activates, feeds the ground coffee into the espresso group, after which the espresso
group closes and the coffee is pressed.
After this hot water release valve is opened towards the espresso group, the internal pump turns ON and
hot water from the boiler reaches the espresso group.
The water flows through the pressed coffee tab and flows out into the cup.
After the set amount of water has flown through the espresso group, the flow stops and the used coffee is
disposed of into the waste container.
Adding the foamed milk into drinks (FRESH MILK option)
Milk is taken from the milk storage container by the milk supply tube, mixed with air and supplied to the
cappuccinatore. Steam is also supplied from the steam boiler to the cappuccinatore for foaming milk.
To avoid problems associated with milk dispensing locate the milk container level with the vending machine and make sure that the milk supply tube lies on the bottom of the container and has no kinks.
To adjust the milk flow rate from the container the Hofmann clamp (see fig. 4.2 pos. 8) is used, which is
included in the vending machine scope of delivery with FRESH MILK option. The milk flow rate is adjusted
by the clamp screw (the flow rate is lowered when the screw is tightened, whereby the milk foam becomes
hotter and “airy” and vice versa).
Use only pasteurized and UHT milk!
Milk fat content should be in the range of 2.5 - 3.6%.
The milk should be stored at a temperature range from 3.5 to 7 0С.
7.3 Dispensing the drink
After preparation the drink flows into the cup, which is placed in the disposal area tray, the LED light in
the disposal area changes colour from red to blue and the customer can remove the cup with the drink
from the disposal area.
DANGER BURN! Please be careful, because the machine uses hot water for drinks’
preparation. To avoid any accidents or injuries, do not remove the cup from the disposal area, before the preparation process is completed!

The setting makes sense for vending machines,
making ground coffee (and makes no sense for
INSTANT vending machines). This setting permits/forbids stopping making coffee after the coffee waste container is overfilled. Because there
are no overfill sensors, the vending machine simply counts the number of portions made. A number of wastes that can fit into the container is set
(recommended value – 200). When exceeding the
number of portions made the vending machine
generates an error and stops making coffee. The
error can be reset only by removing the waste
container for a protracted period of time (several seconds) after powering the vending machine
off. By setting 0 the vending machine switches the
waste container overfill control, and the vending

User manual for NERO TOUCH, NERO TOUCH INSTANT
Here drink recipes are specified, which may consist of several steps (ingredients). Each recipe may have a different number of ingredients (up to 4). The sequence of the ingredients in the recipe corresponds to the sequence of the
drink making.
To adjust the recipe:
1. Select a drink (1) which recipe you want to adjust, in the left part of the page.
2. Then choose an ingredient, added into the drink, from a drop-down list of ingredients (2).
3. By using buttons (3) set the required amount of the selected ingredient (the ▲ button increases the amount of
the ingredient, and the ▼button decreases the amount). Set in tenths of a second of the giving out motor spin time.
For coffee drinks, it depends on the mode, selected in the Brewer section, the Adjustable coffee dose setting.
If set to NO, this parameter makes no difference. If set to (7..9), then for the values from 0 to 70 the dosage of 7
g of ground coffee will be grinding. For the values from 70 to 90 the dosage of coffee in tenths of a gram is specified
here. For the values above 90, the dosage of 9 g of coffee will be ground.
If it has the VARIO-BREWER installed, then in this setting the values from 70 to 150, which is a dosage of coffee
in tenths of a gram, are specified here (all that is less than 70 means 7 g, and all that is above 150 means 15 g). 4. By using the buttons (4) set the amount of water added to the drink:
- for hot water - set in the milliliter;
- for fresh milk - here the time in tenths of a second, during which the vending machine supplies steam to the
cappuccinatore, is set.
5. The button (5) is used for adding an ingredient in the drink recipe Ingredient field.
Note: To make the ingredient addition to a drink visual, the addition of another ingredient will be shown
as the new sector of the cup, which color will correspond to the added ingredient.
6. The button (6) is used for removing an ingredient from the drink recipe Ingredient field.
Note: The button appears when there’s more than one ingredient in the drink recipe, otherwise the button

VALUE
The setting is meaningless for instant coffee vending
machines (INSTANT). Specifies the coffee group type.
The value (NO) prohibits the changing of the coffee
powder dosage in recipes (only one portion will always
be ground, set by the dosing unit setting). The value
(YES) (7..9) activates the mode, where the ground portion can be programmed in a range from 7 to 9 g (it’s
programmed in tenths of a gram by selecting the number in a range from 70 to 90).
ATTENTION! Before activating this mode make sure
that the used group can brew coffee from 9 g of coffee
powder (in order to find out how to switch the group to
the 9 g mode, consult the service center).
ATTENTION! Before activating this mode, adjust the
dosing unit in such a way that one coffee portion will
be 7 g sharp (if the dosing unit permits, e.g., adjusting
the values to 6.8 and 7.2, select 6.8 g) for more information contact the service center. The value of (VARIO-BREWER) (7..15) permits programming the coffee
powder dosage in the range from 7 to 15 g (by the
number from 70 to 150). But for doing so the vending
machine should have the special version of the coffee
group with motorized changing of the brewing camera
volume, where the coffee brewing is realized (otherwise when selecting this option the vending machine
will show the vario-group error and will stop making
coffee based drinks).
ATTENTION! Before activating this mode, adjust the
dosing unit in such a way that one coffee portion will be
7 g sharp (if the dosing unit permits, e.g., adjusting the
values to 6.8 and 7.2, select 6.8 g) for more information

This setting makes no difference for instant vending machines. Selecting (YES) permits quickening
the making of coffee-based drinks at the expense
of pre-grinding (by grinding coffee before the customer selects a drink). Also if selecting (YES), in
the event the vending machine runs out of coffee
beans, it will display an error before the customer
selects a drink (the error occurs at the moment of

Completion delay after coffee
Sets time (in tenths of a second) after coffee pouring (after the valve closing) for which the vending
machine will wait (another 2 seconds are added

During this time the coffee group will not return
to the open state, will not add the next ingredient
and will not give out the cup if this ingredient was

APPENDIX A - HYDRAULIC CIRCUIT FUNCTIONAL CHECK METHOD
The vending machine hydraulic circuit is a set of assemblies and pipes, meant for making and giving
out of drinks.
The hydraulic circuit principle of operation is the following:
When connecting the vending machine to the water supply network, water is supplied through the water
supply solenoid valve.
When connecting the vending machine to the autonomous water supply system from canisters/bottles
- water is pumped into the hydraulic circuit by using the delivery water pump.
Then water is supplied via the tubes to the vending machine float chamber and water filter, water meter
and water pump into the boiler.
In the FRESH MILK option water is supplied via the tubes to the vending machine float chamber and via
the water filter to the splitter, where it’s split into two lines: the first one is via the water meter and water
pump into the boiler, and another one – via the water pump into the steam boiler.
The boiler heats the water up to the required temperature and then depending on the chosen drink it
is supplied to one of the four boiler channels: to espresso group, (Coffee) mixer (for NERO INSTANT),
(Chocolate/Milk) mixer, (Vanilla) mixer, or directly to the output nozzle (when choosing the hot water),
where the mixing with the required ingredient and giving out of the chosen drink to the customer via the
output nozzles occurs.
In the steam boiler water is heated up to steam condition and then via the steam supply valve (the valve
has to positions – open/close) is supplied to the cappuccinatore, where milk is also supplied. In the cappuccinatore, the milk foaming occurs with subsequent foam supplying into a drink.
Excess water and steam (FRESH MILK option) are supplied to the waste container.
Since the vending machine hydraulic system uses hot water under certain pressure, the essential
condition for providing safe and dependable operation of the vending machine is the successful operation
of the hydraulic system, which should be regularly checked in accordance with methods, specified in the
appendix, and follow all the requirements put down in this manual.
The vending machine hydraulic system operation check should be executed with the open door with the
inserted open door trip.
Before starting the vending machine for the first time visually check that all the hydraulic circuit elements
are securely interconnected, and water supply connection parameters correspond with the parameters,
specified in this manual. Failure to follow these requirements can lead to vending machine breakdown.
When starting the vending machine for the first time visually check the system has no leaks.
Pay particular attention to the boiler and steam boiler (FRESH MILK option) because these units heat
water to high temperatures.
Visually check that there are no leaks at the boiler joints, otherwise the further operation of the vending
machines until the malfunction repair is PROHIBITED.
The boiler and steam boiler (FRESH MILK option), used in the vending machines, are meant for safe
operation with the rated pressure much higher than the operating pressure.
For safe boiler maintenance and repair, the vending machine should be disconnected from mains, and
water should be drained from the hydraulic system in accordance with this manual.
DISMANTLING THE BOILER BEFORE IT’S FULLY DRAINED IS PROHIBITED!
Boilers installed in the vending machines should undergo detailed examination, conducted in two stages:
Stage #1 - the examination is conducted on “cold boiler”, the boiler should be disconnected from the
system. On this stage, the boiler is thoroughly inspected to eliminate the facts of corrosion, erosion, deformation, cracks and other external defects.
Stage #2 - the examination is conducted on “hot boiler”, the boiler should be connected to the system.
The vending machine should be connected to the water and electrical supply and switched on.
The examination should be executed by using the soapy water for clear identification of leaks in case
of their detection. After such examination, flush the hydraulic circuit several times in accordance with this
manual.
Version 1.1 / December 2017
page 110
ТМ
User manual for NERO TOUCH, NERO TOUCH INSTANT
At this stage, the boiler operation in the system, together with safety elements are thoroughly inspected.
To prevent scale formation on the boiler heating element, which may lead to vending machine breakage,
flush the vending machine system by special anti-scaling agents that are suitable for vending machines at
least once a month or oftener, depending on the characteristics of water, used in the vending machine.
The vending machine operators should undergo appropriate training for conducting maintenance and
working with the vending machine hydraulic system, as well as understand all hazards that may arise from
