4 INSTRUCTIONS FOR TECHNICAL STAFF

4.1 Plumbing hookup

PLUMBING HOOKUP

The water pipelines and electricity supply cable lead out of the bottom right-hand corner of the appliance.

Connect the water intake hose to a connector with ¾” gas threaded fitting, fitting the filter A provided (in

models with Acquastop, the filter and ring-nut form a single unit). The connection to the water mains must

only be made with new hoses; the use of old or worn hoses is not permitted.

FOR MODELS WITH A WATER SOFTENER

an ‘approved’ double check valve or some other no less effective device providing backflow prevention protection to at least

fluid category two shall be fitted at the point of connection between the water supply and the fitting or appliance.

FOR MODELS WITHOUT A WATER SOFTENER

an ‘approved’ single check valve or some other no less effective device providing backflow prevention protection to at least

fluid category two shall be fitted at the point of connection between the water supply and the fitting or appliance.

The dynamic water supply pressure must be between 1 and 6 bar; if it is higher, installation of a pressure reducer is necessary.

If the pressure is less than 2.5 bar it might be necessary to fit a special pump on the appliance to ensure optimal performance.

Contact the After-Sales Service. It is essential to fit a main stop tap on the water intake deliver pipeline; the tap must be

accessible after installation of the appliance, so do not install it behind the dishwasher. The stated cycle duration applies to

appliances supplied with hot water >50°C<60°C. If the dishwasher is supplied with cold water, the cycle duration might increase

depending on the intake water temperature. Drainage: The dishwasher is fitted with a drain pump and can operate with drain

connections on the floor or wall. Refer to the connection diagram for the maximum permitted height of wall drains – (see

TECHNICAL DATA)

Warning: make sure that the intake and drain hoses are not bent, constricted or crushed after installation.

When installing the drain hose to a siphon with valve, the maximum height of the drain outlet is reduced to 600 mm.

4.2 Electrical connection

The dishwasher and any additional equipment must be connected to the electrical system by authorised,

skilled staff, in accordance with the relevant regulations; also comply with the technical instructions for the

connection. The total rated power is stated on the appliance’s technical data plate. The electrical protection

devices fitted for the dishwasher must serve this appliance only. The user must have a master switch and a

differential safety breaker, with rating suitable for the appliance’s characteristics, installed on the electricity

supply line in accordance with the relevant regulations. These switches must be installed close to the

dishwasher, be easily accessible after installation, and provide complete disconnection from the electrical

mains in overvoltage class III conditions.

Warning!

The dishwasher is always powered up unless the master switch is turned off.

Connect the appliance to the user’s earth system. The terminal for the connection is in the bottom right-

hand corner of the appliance. The earth wire (PE) is yellow-green in colour, the neutral wire (N) is blue and the

live wires (L1, L2, L3) are black, grey and brown. In the event of single-phase connection (230V-1N~), the

connection to the electrical mains must be made using a cable with plug compliant with the relevant

regulations.

THE POWER SUPPLY CABLE, IF FITTED, MUST BE REPLACED BY THE MANUFACTURER OR AN AUTHORISED

SERVICE CENTRE IN ACCORDANCE WITH THE TECHNICAL DATA SPECIFIED ON THE WIRING DIAGRAM

SUPPLIED WITH THE APPLIANCE, TO PREVENT ALL RISKS.
