DOOR SWITCH
When opening the door a special switch disconnects the power from the machine electrical system to allow the operations described below, regarding loading and routine cleaning, in full safety.
All operations which require the machine to be ener­gised with the door open must be carried out EXCLU­SIVELY by qualified personnel who are aware of the specific risks of such condition.
HYGIENE AND CLEANING
According to current safety and health rules and regula­tions, the operator of an automatic vending machine is responsible for the hygiene of materials that come in contact with foodstuff; therefore he must carry out mainte­nance on the machine to prevent the formation of bacteria.
At installation the hydraulic circuits and the parts in contact with foodstuff should be fully sanitised to remove any bacteria which might have formed during storage.
The machine is not suitable for outdoor installation, it must be installed in a dry room where the temperature remains between 2°C and 32°C. It is advisable that specific sanitising products are used for cleaning also the surfaces which are not directly in contact with foodstuff. Some parts of the machine can be damaged by strong detergents. The manufacturer declines all responsibility for damage caused by noncompliance with the above instructions or by the use of strong or toxic chemical agents.
Do not use sprayed water for cleaning. Before starting any maintenance operations requiring
parts of the unit to be removed, the machine must always be switched off.

INSTALLATION
Installation and the following maintenance operations
should be carried out with the machine switched on and
therefore by qualified personnel only, who are trained in the correct use of the machine and informed about the specific risks of such situation. To energize the system with the open door, simply insert the special key into the slot (see Fig. 14). The door can be closed only after removing the yellow key from door switch and lowering the machine top panel. The vending machine is not suitable for outdoor installa­tion. It must be positioned in a dry room where the tempera­ture remains between 2° C and 32° C, and not where water jets are used for cleaning (e.g. in large kitchens, etc.).
At installation the hydraulic circuits and the parts in contact with foodstuff should be fully sanitised to remove any bacteria which might have formed during storage.
Installation on the base cabinet
The machine can be installed on a base cabinet (optional), which can house the coffee grounds bag, the water supply kit and, in the case of very hard water, the softener unit.
UNPACKING THE VENDING MACHINE
After removing the packing, ensure that the machine is intact. If in doubt do not use the machine.
No packing elements (i.e. plastic bags, polystyrene foam, nails, etc.) should be left within the reach of children, as they are potentially dangerous.
Packing materials must be disposed of in authorised containers and the recyclable ones must be recovered by qualified compa­nies.
Important notice!!
The machine should be positioned with a maximum incli­nation of 2°. If necessary provide proper levelling by way of the adjust­able feet included (see Fig. 15).

INSERTING THE PRODUCT LABELS
The labels indicating the available product selections are supplied with the machine and must be inserted into the special slots at installation, fitting the cover. According to the model, some buttons may not be used (refer to the selection dose table).
INSTALLATION ON A CABINET
The machine can be positioned on a base cabinet (op­tional). With the base cabinet the used capsules are discharged into the coffee grounds bag housed in the base cabinet; therefore it is necessary to fit the capsule dis­charge conveyor onto the coffee unit for correct ejection of the used capsules.
CONNECTING THE MACHINE TO THE WATER MAINS
The machine must be connected to the drinking water mains, taking into account law provisions in force in the country where the machine is installed. The water pressure must be 0.05 to 0.85 MPa (0.5 - 8.5 bar). Run some water from the mains until it is clear and without impurities. Use a hose capable of withstanding the water mains pressure and suitable for use with foodstuff (min. inside diameter of 6 mm) to connect the water supply to the fitting (3/4" gas) of the water inlet solenoid valve (see Fig. 16).

It is good practice to install the water supply tap outside the machine in an easily accessible position.
OVERFLOW DEVICE
The water inlet solenoid valve (see Fig. 16) is equipped with an overflow device which mechanically stops the water inlet if there is a malfunction in the solenoid valve or in the boiler water level control device. To restore normal operation, proceed as follows:
- disconnect the electricity from the machine;
- drain the water contained in the overflow hose;
- shut off the water supply using the tap outside the machine;
This fundamental safety requirement must be duly verified, and if in doubt the system must be carefully tested by qualified technicians.
The power supply cable is of the type with a fixed plug. Replacement of the power cable (see Fig. 17) should be carried out by qualified and suitably trained personnel only using cables type HO5 RN-F or HO5 V V-F or H07 RN-F with a 3x1-1.5 mm2 section.
Do not use adapters, multiple sockets and/or exten­sions.
Fig. 17
1 - Lift cover 2 - Cable clamp 3 - Power supply cable
- loosen the nut which secures the solenoid valve supply hose to relieve the water mains residual pressure and then tighten again (see Fig. 16);
- open the tap and switch the machine on.
CONNECTING THE MACHINE TO THE POWER SUPPLY
The machine is designed to operate under single-phase 230 V~ voltage and is protected by 15 A fuses. Before making the connection, ensure that the rating corresponds to that of the power grid, and more specifi­cally:
- the supply voltage rating must be within the range recommended for the connection points;
- the main switch should be capable of withstanding the peak load required, and at the same time ensure proper omnipolar disconnection from the power grid with an opening gap of the contacts of at least 3 mm.
The switch, the power outlet and the plug must be located in an easily accessible position.
The electrical safety of the machine is ensured only when it is correctly earthed according to the safety standards in force.
THE MANUFACTURER DECLINES ALL RESPONSI­BILITY FOR ANY DAMAGE CAUSED BY NONCOMPLI­ANCE WITH THE ABOVE MENTIONED PRECAUTIONS.

When opening the door a special micro-switch discon­nects the power from the machine electrical system. To energize the system with the open door, simply insert the special key into the slot (see Fig. 14).
With the door open there is no access to energised parts. Inside the machine, the only parts that stay energised are those protected by covers and carrying a plate with the warning “disconnect the power before removing the protective cover”.
Before removing such covers disconnect the power supply cable.
The door can be closed only after removing the yellow key from door switch and lowering the machine top panel.

INSTALLING THE PAYMENT SYSTEM
FILLING THE WATER SYSTEM
The machine is sold without payment system, there­fore the installer of such a system has sole responsi­bility for any damage to the machine or to things and persons caused by incorrect installation.
Install the coin mechanism paying attention, according to the type used, to:
- secure the coin mechanism onto the support, choosing the most suitable securing holes;
- open the board support removing the two fastening screws;
- loosen the fastening screw and adjust the coin slot chute according to the coin mechanism opening;
- loosen the fastening screws and adjust the coin return lever.
If the air-break device indicates the no-water condition for more than 10 seconds after the machine has been switched on, an installation cycle will automatically be started, and namely:
- the display will show
“INSTALLATION”
for the entire duration of the cycle;
- the air-break and the boiler are filled;
- (for espresso models only) the coffee solenoid valve is opened so that air may be bled from the boiler and 800 cc. of water filled.
N.B.: If there is no water flow from the mains during the installation cycle, the machine will be blocked until the water is resumed or the machine is switched off.
This operation must be carried out manually, using the special function from the “test” menu in “Technician”
mode, if the kit (optional) for water supply from an internal tank is fitted or after any maintenance requiring
the boiler to be emptied but not the air-break.
WATER SOFTENER UNIT

2 - Coin chute 3 - Coin return lever
If a payment system is not used, it would be advisable to lock the coin return lever by inserting a screw into the lever lock slot.
The machine is sold without water softener. Should the water be very hard, a water softener unit can be installed. The water softener, available as accessory, must be replaced or regenerated regularly following the directions from the manufacturer.
INSTALLATION IN A BANK OF MACHINES
The machine control system is prearranged for the con­nection in a bank of vending machines using special kits. This permits the use of a single payment system and remote connection (GSM) for more machines. In the event of installation in a bank of machines, it can be configured a “Master”, i.e. having control over the second machine, or as “Slave”, i.e. leaving the control to the other machine.

COFFEE CAPSULE DISPENSING CYCLE
VENDING MACHINE
The capsule dispenser allows loading of capsules in a casual manner since it can automatically turn them, straighten them and bring them into the release position. The dispenser is composed of two parts:
- the capsule orientation and drive system;
- the capsule detection and release system.
ORIENTATION SYSTEM
The system, as well as the container, is composed of a motor that can rotate in both directions. The motor drives the selection disk by means of an intermittence system and at the same time operates the agitator by means of a drive pin. The weight spreader at the centre of the container has the purpose of avoiding that the entire weight of the capsules bears onto the orientation mechanism. When the capsules are moved by the agitator the are positioned sideways in the separator ring. The selector disk has six cells with the seat for the capsule edge positioned alternated inside and outside. When a capsule coincides with the shape in the selector ring it is loaded into the cell. The device continues rotating until a capsule falls in the positioning chamber. If after a few loading attempts the presence of the capsule is not detected, the agitator’s rotation is inverted and the cycle repeated. The rotation direction is inverted also after a few cycles in the same direction to facilitate the even positioning of the capsules. The rotation inversion to search capsules is performed a few times, after which the coffee-based selections are blocked for a “No coffee” failure. During this time, if a coffee-based selection is made the message “Wait please” is displayed. If for any reason the motor does not complete the rotation within a certain time, the rotation is inverted; if also this attempt fails, the coffee-based selection are blocked with a “No coffee” failure.
DETECTION AND RELEASE SYSTEM
When a capsule falls into the positioning chamber it is placed vertically onto the release levers thanks to the special shape of the chutes and of the stabiliser guides. The capsule detection lever signals to the machine, by means of a photocell, to stop the search in the orientation system. At the first loading (release device empty) the search in the orientation system will continue for positioning the second capsule. If necessary the capsule should be positioned manually. When the machine is switched on, the capsule search is started automatically. During the machine normal operation there must always be two capsules into release position.

If after releasing the capsule this is still detected in the positioning chamber, the brewer unit is rotated to eject the capsule and a second release attempt is made. If the capsule is still detected, the coffee-based selections are blocked with a “Coffee release” failure.

COFFEE DISPENSING
When a coffee-based selection is made a capsule is released into the brewing chamber, that when in stand-by position is vertical (see Fig. 20). The ratiomotor handle rotates 180°, making the brew chamber swing and lowering the upper piston (see Fig.
21). The lock lever is positioned into the seat, stopping the piston pressure from making the mechanism move back. Due to the water pressure, the hydraulic piston is lowered until it seals onto the capsule edge and the brewing piston

ing the ground coffee inside the capsule. At the end of dispensing, the water inside the capsule flows out through the 3rd way of the dispensing solenoid valve and the bottom of the capsule resumes its concave shape. The hydraulic piston is released and returns to the stand­by position. The ratiomotor rotation continues, lifting the piston and the lower ejector. At the same time, when the brewing chamber returns to its vertical position, the ejection levers push the used capsule and drops it. The lower ejector returns to the rest position.

pierces the protective film. When the dispensing solenoid valve opens, water reaches the ground coffee through the pierced protective film. The water pressure pushes the concave bottom of the capsule against the piercing filter. The conical needles of the piercing filter pierce the bottom of the capsule, permitting the brewing of coffee and retain-
