CUP DISPENSING

• This is the first operation that the vending

machine activates - except for 'without cup' dispensing selection.

• The motor that engages the nozzle support

is actuated to retract the support and let the cup drop into the dispensing outlet.

• The motor inside the cup dispenser moves

the scrolls in order to separate and let the cup fall into the special support fork inside the dispensing outlet.

SAECO GROUP 500N E : version equipped with a plastic brew group, 4 instant products and 48 mm grinders.

SAECO GROUP 500N E PLUS: version equipped with a plastic brew group, 4 instant products and 64 mm grinders.

SUGAR AND STIRRER DISPENSING

Where provided for and required, a preset maximum dose of sugar is dispensed, with the possibility to stop the machine when the required dose has been reached.

Dispensing is divided in the following phases:

• the dragging motor of the channel is engaged and conveys the sugar into the cup.

• the gearmotor activates the sugar container screw, dispensing the desired quantity of product into the conveyor tube.

• the solenoid is activated, and the stirrer is directly dispensed into the cup through a special channel (fig.9).

INSTANT BEVERAGES

This process takes place only after the dispensing of the cup, the sugar and the stirrer. According to the beverage selected and the model of the vending machine the following processes are enabled for the beverage brewing. model of the vending machine the following processes are enabled for the beverage brewing.

• If fitted, the motor mixer is engaged.

• The solenoid valve for instant products (ref. '1' fig.7), installed on the coffee boiler, is engaged and conveys the programmed quantity of water into the mixer. Then, the pump (ref. '2' fig. 7) is engaged and, controlled by a special electronic device (volumetric counter ref. '3' fig. 7), it dispenses the programmed quantity of water.

fig. 7

• The gearmotor of the instant product engages the screw container, dispensing the desired quantity of product into the mixer.

• Once the preset quantity of water and powder is dispensed, the mixer is disconnected.

• controlled by the appropriate electronic device (volumetric counter - ref. '3' fig.7), the pump dispenses the preset quantity of water sucked from the coffee boiler.

fig.7

• the brew group gearmotor goes back to its rest

position while the used coffee tablet is ejected.

According to the type of program set (see programming menu), the above procedure for the grinder and dosing unit engagement can take place in reverse.

fig.9

• the group rotation gearmotor moves the group onto the brewing position and compresses the coffee tablet (fig.9).

6.4 Water mains connection

Before connecting the vending machine to the water mains, make sure the water:

- is drinking (if possible by means of test laboratory certification)

- has a pressure ranging between 1.5 bars and 8 bars, otherwise use a pump or a water pressure reducer accordingly

- if not already fitted, install a tap in an accessible position, so as to separate the equipment from the water mains, should it be necessary (fig.17).

- connect the tap to the vending machine, using a copper or nylon pipe, suitable for foodstuffs and for the purpose of bearing the water supply pressure. should a flexible hose be used, it is necessary to assemble the reinforcement bearing inside, supplied with the machine.

- The connection provided for is a 3/8 gas-type fitting.

6.5 Electric Mains connection

The vending machine is designed to operate with single phase voltage at 230 Volts and is protected by 8A rapid fuses.

We suggest checking the following:

- the mains voltage of 230 V shall not exceed a ± 6% fluctuation;

- the power supply must be suitable to the machine.

- a diversified protection system shall be connected

fig.17

- let some water flow out of the tap so that to eliminate possible traces of impurities and dirt (fig. 18).

The machine shall be earthed in observance with operating safety rules in force.

For this reason, verify the system earth wire connection to ascertain that it is efficient and in compliance with national and European electric safety standards.

If necessary, have the system inspected by qualified personnel.

- The vending machine is provided with a power cord (fig. 19)
