3.5.3 Open door circuit-breaker
In case of opening the vending machine’s door, a special circuit-breaker cuts off the power, which runs
the devices and units inside the machine. All checking, loading and cleaning operations must be performed
safely. Any operations with open door, should only be performed by qualied personnel only.
Figure 12а Figure 12b Figure 12c
To turn ON the power, with the door open,
it is necessary to insert the special key (see
gures 12 a, b, c) into the breaker and turn it
through 900 until it is xed. Please make sure
to remove this key before closing the door.
3.5.4 Containers for ingredients and coffee beans
For NERO:
The NERO vending machine comes with three types of containers for ingredient storage: containers for
coffee beans (see gure 13), containers for ingredients such as “Chocolate” and “Milk” (see gure 14a) and
container for “Vanilla” (see gure 14b).
Figure 13 Figure 14а Figure 14b
For NERO INSTANT:
The NERO INSTANT vending machine comes with a single type of container for drinks preparation:
ingredients containers (see gure 15).
Figure 15

ТМ
To install and remove the coffee bean container (for NERO):
With open vending machine door, pull the container’s clamp (1),
which is located in the left upper corner of the machine (see gure
16) and holding the clamp remove the container.
The container can be installed in the reverse order of actions.
Filling the coffee beans into the container (for NERO):
To ll the container remove the lid (see gure 13) from top of the container and pour in the coffee beans.
1
Filling the instant ingredients containers:
• Open the vending machine’s door;
• Lift the top lid of the machine;
• Lift the lid of the required container;
• Fill in the ingredient.
Figure 16 - Clamps of coffee bean container
Figure 17
If necessary (for convenience in lling) the containers can be re-
moved from the vending machine. For the purpose:
• Turn the container’s “nose” upwards;
• Slightly raise the container using the “nose” in such a way that
the container’s base grip would be removed from the body;
• Pull out the container.
The ingredient is supplied from the container using a reducer-mo-
tor, which is installed behind the container. The reducer-motor sup-
plies the required dose of ingredient into the mixer.
The quantity of the ingredient for each drink is set in the drinks
recipe menu. The quantity is equal to the duration of rotation of the
motor multiplied by 100.
ATTENTION: After lling the container, make sure that there are no foreign objects in the
container.
Make sure that the ingredient did not get compressed during the lling process.
Remove all remnants or spill-overs of ingredient from the outer surfaces of the container or
the machine’s parts.

3.5.5 Waste container
The liquid waste container is situated in the lower left part of the machine. You must drop the oat into
this container. The given oat acts as the sensor indicating the container’s level of lling.
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 es-
presso group throws out into the waste container, situated in the lower left side of the machine. The quan-
tity of waste is monitored programmatically.
When the quantity of drinks made of ground coffee reaches 150, such drinks are taken ofine and are
no more available. To reset the waste counter, you must remove the container from the working machine
for at least 10 seconds, remove the waste and replace the empty container into the machine.
3.5.6 Autonomous operations kit
In its standard conguration the vending machine is congured 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 gure
4 position 5), which from one end is connected to water inlet 2 (see gure 8) and from the other end of the
tube is immersed into the source of water (canister/bottle).
 3.5.7Connectingthevendingmachinetowatersupplymains(optional)
The vending machines can also be connected directly to the water supply mains, taking into consider-
ation the applicable laws of the country of use. The inlet nozzle for connection to the water supply mains
is situated on the rear panel of the vending machine (see gure 8 position 1) and comprises of a threaded
connector of diameter ¾”. The machine is connected using a pipe, which can handle the pressure of the
water supply and which is suitable for use with food products (minimum inner diameter of 6mm).
The water pressure in the supply line must be in the range of 0.05 to 0.85 MPa (0.5 – 8.5 bar).
Before connecting the vending machine to the water supply mains:
• Set the switch on the switch board of the machine to position “O” / “OFF”;
• Unplug the machine by removing the plug from the power socket;
• Remove the vending machine’s rear panel by removing the screws;
• Disconnect the pump connectors with blue and white wires (see gure 18a position 1, 2);
• Disconnect the silicone tube (see gure 18a, position 3);
• Connect the silicone tube and power connectors to the electric valve (see gure 18b).

ATTENTION: The machine must be connected to the water supply mains, only by a qualied
technician!
It is recommended to place the water supply tap (valve) outside the machine’s body at an easily acces-
sible spot.
After connecting the water supply mains replace the machine’s rear panel, connect the vending ma-
chine to the power supply and switch the button on the switch board to the “I” / “ON” position.
After that change the vending machine’s congurations (settings). For the purpose access the service
