When switched on, the machine goes through a control rotine to determine which payment systems are actually installed and therefore configure the correct system.

CONNECTING THE MACHINE TO THE POWER SUPPLY

The machine operates under a single-phase 220 V~ 60 Hz voltage and is protected by 10 A fuses, located inside the support cabinet (see Fig. 9). 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 main switch is protected by a differential switch.

The switch, the power outlet and the plug must be located in an easily accessible position.

The power supply cable is of the type with a two-pole straight plug of the non-detachable type. Any replacement of the power supply cable should be made by qualified personnel only, using cables of the type H05 RN - F or H05 V V - F with a section of 3x1-1.5 mm2.

The electrical safety of the machine is ensured only when it is correctly connected to an efficient earthing system according to the safety standards in force.

This fundamental safety requirement must be duly verified, and if in doubt the system must be carefully tested by qualified technicians.

Do not use adapters, multiple sockets and/or extensions.

Before switching the machine on, ensure that the water tank is correctly filled.

THE MANUFACTURER DECLINES ALL RESPONSIBILITY FOR ANY DAMAGE CAUSED BY NON-COMPLIANCE WITH THE ABOVE MENTIONED SAFETY RULES.

DIFFERENTIAL SWITCH

The differential switch has the following characteristics:

- maximum current: 15 A

- maximum tripping current to earth: 15 mA

- breaking capacity: 1.5 KA This switch is fitted for the purpose of protecting from

any overcurrent and earth leakage, also protecting persons from contact with live parts.

If the switch is triggered again when is reset after tripping, the system must be tested by qualified personnel.

DOOR SWITCH

When opening the door a special microswitch (see Fig. 8) disconnects the power from the machine electrical system. The trasformer inside the support cabinet remains energised. The differential switch must be used to disconneted it.

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 machine from the power grid.

To energize the system with the open door, simply insert the special key into the slot (see Fig. 8).

All operations which require the machine to be energised with the door open must be carried out by qualified personnel who are aware of the specific risks of such condition.

WATER SOFTENER UNIT

The machine is sold without water softener. Should the water be very hard, a water softener cartridge can be installed, using the connections provided in the hydraulic circuit. The cartridge should be replaced according to the manufacturer’s instructions.

INSERTING THE PRODUCT LABELS

The menu and instruction labels are supplied with the machine and must be inserted at the time of installation according to the layout and to the language (see “selection dose” table).
