TECHNICAL DESCRIPTION

5.1 Permitted use

The vending machine is to be used exclusively for the dispensing of beverages, prepared by mixing foodstuffs with water (by brewing, as to coffee). To this purpose, use products that the manufacturer has declared as being suitable for vending in open containers. Beverages are brewed in suitable plastic cups, which the machine dispenses automatically. The stirrer used for mixing sugar is automatically dispensed. Beverage should be drunk at once and under no circumstances can they be kept for subsequent consumption.

5.2 Versions and models

- show any crushed parts, sign of shocks, buckling or breaking

- show wet parts or signs that could lead to suppose its exposure to rain, frost or heat

- show signs of tampering

Warning:

This manual refers to the top-of-the -range model: it is therefore possible to find descriptions or explanations not relating to the machine you have.

5.3 Basic operating concepts

During normal operation, the vending machine is in standby mode. By introducing the amount corresponding to the price displayed and by pressing the key relevant to the desired beverage, you will start the dispensing cycle. This one basically consists of:

BEVERAGE SELECTION

The machine can dispense 8 beverages. A beverage can be selected according to the following conditions:

 the vending machine has reached the set

temperature after start-up. Otherwise, once a key is pressed, the display shows the message  PLEASE WAIT.

English

 the available credit is sufficient or the vending

machine has been set in free mode. If this is not the case, the display shows the message INSERT ...;

 there is no error condition that prevents

beverage brewing. If it is not the case the display shows the error message BEVERAGE... OUT OF SERVICE alternated to a NOT AVAILABLE message;

 the selected beverage has been enabled. If

this is not the case, the message NOT AVAILABLE will be displayed;

 the selected beverage is not prevented.

Otherwise, before pressing the key, the message BEVERAGE ... alternated to a NOT AVAILABLE message is displayed. After pressing the key, the display shows NOT AVAILABLE;

During hot beverage brewing:

- payment systems are disabled;

- the first line on the display shows the

programmable dispensing message (default message is: WAIT FOR PRODUCT).

Beverage selection

If the vending machine has not been programmed to freely dispense beverages insert the required credit Press the key corresponding to the beverage requested. After beverage dispensing, the message REMOVE CUP is displayed. Take the beverage from the dispensing outlet.

Warning

Not to burn your hand, wait for the signal REMOVE CUP- before introducing your hand. Do not open the dispensing outlet door while the VM is brewing. In case of failures or product missing during the brewing phase, the display indicates the causes.

CUP, SUGAR AND STIRRER DISPENSING

This is the first operation that the vending machine activates (except for without cup dispensing selection):

 the cup bracket motor is activated and moves

under the cup chute. At the same time, it operates the cup scrolls to separate the first cup and let it drop into the special support fork.

 The same motor draws the cup under the

sugar dispenser  there it stops for 2 seconds. In this way dispensing is enabled and, where it is set or required, a stirrer is dispensed. Finally, it sets the cup under the beverage brewing nozzles.

 The stirrer dispensing is controlled through a

solenoid which actuates the stirrer ejector. The stirrer is then dropped into the cup by means of the proper chute.

When selecting a beverage, sugar is dosed through a motor that activates the sugar hopper screw.

INSTANT BEVERAGE BREWING

This process takes place after dispensing of cup, sugar and stirrer. According to the type of beverage selected and machine model, the following processes are activated.

 If present, the motor mixer starts.

 the instant product solenoid valve (ref.1' fig.5),

located on the coffee boiler, starts and allows to fill the mixer with the preset amount of water. The pump (ref.2' fig.5) is then activated and the preset amount of water dispensed, under the control of an appropriate electronic device (volumetric meter) (ref.3' fig.5).

 the unit rotation gear motor activates, thus

moving the unit to the brewing position. The coffee tablet is pressed simultaneously.

 the pump brewing the set quantity of water

activates, under the control of an appropriate electronic device (volumetric meter) (ref. 3 fig. 5).

 the brew group gear motor is restarted, and

goes back to the rest position. During this movement the coffee tablet is ejected.

The grinder and dosing unit activation sequence can take place in reverse order, according to the program selected (see programming menu).

 once the pre-set amount of water and product

is dispensed, the mixer is disconnected.

ESPRESSO COFFEE BREWING

This process takes place only after the dispensing of cup, sugar and stirrer.

 the grinder (ref.1 fig.6) is activated until the

quantity of coffee set on the dosing unit (ref.2 fig.6) is reached

 the activation of the dosing unit solenoid (ref.

3 fig. 6) causes the door to open and, as a consequence, the coffee is dispensed into the cup.

6.7 Installation

IMPORTANT: When switched on, the machine automatically fills the water circuit and the related boilers. For a correct automatic installation in case of a water softener system being used, it is necessary that the latter is completely filled with water and properly relieved of any air bubbles.

6.7.1 Cleaning and filling of resinbased water softener

IMPORTANT: Before installing the water softener in the machine and using it, clean the resins and fill the water softener. Then install the

water softener already filled with water and cleaned.

- fill up the water softener and let the water flow out of the drain hose until it is clear (fig.20).

In order to fill in the water softener before installing it on the machine, stick to the following instructions:

- Insert the hose of the bottom tap into a drain container suitable for this purpose.

- open the bottom tap (fig. 19) and the upper plug of the water softener so as to remove the air bubble.

fig.20

- close upper plug and turn off the bottom tap

fig.19

6.7.2 Water circuit filling

The machine automatically activates the pump and starts filling the espresso coffee boiler.

English

During the setting-up phase:

- the coffee boiler and the water tank are filled up

IMPORTANT:

Before powering the machine, thus starting the automatic installation:

1. Make sure that the water softener is filled with water and the air bubbles removed.

2. Load the reachable columns of the cup holder.

NOTE:

If the filling of the boiler is not successful, the machine cannot be set into service. A failure message will be shown on the display. Should it be the case, eliminate the cause and reset the error recorded (section 8 Programming and maintenance menu), then repeat the automatic installation, switching the machine on once again. After a testing phase on start-up, the machine automatically fills the water circuit of the tray equipped with a float and of the brew group boiler. During this stage, the heating element of the boiler remains automatically off. If the machine detects that the boiler is already filled, it passes to the heating stage.

- once the water circuit is filled, the heating phase starts up, thus switching on automatically the boiler heating element.
