3.5.5 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 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 offline 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 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 figure
4 position 5), which from one end is connected to water inlet 2 (see figure 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 figure 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 figure 18a position 1, 2);
• Disconnect the silicone tube (see figure 18a, position 3);
• Connect the silicone tube and power connectors to the electric valve (see figure 18b).
