POSITIONING:
4 INSTRUCTIONS FOR TECHNICAL STAFF
4.1 Plumbing hookup
Water supply and drain hookup
The water pipelines and electricity supply cable lead out of the bottom righthand 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
aquastop, 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.
The dynamic water supply pressure must be between 1 and 6 bar; if it is higher, installation of a
pressure reducer is necessary.
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. 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)
Caution: 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.
Caution: the indoor system and premises in which equipment for institutions is installed
must comply with the relevant regulations.
The manufacturer declines all liability for direct or indirect injury or damage deriving from failure
to comply with these regulations.
Before installation, check that there are no objects or materials in the vicinity which may be
damaged by steam or splashes of washing solution, or that any such items are suitably protected.
Place the dishwasher in the chosen point and remove the protective film.
Level the dishwasher (with the aid of a spirit level) on its adjustable feet to ensure that it is stable;
all other mounting solutions must be approved by the manufacturer.

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 MUST BE REPLACED BY THE MANUFACTURER OR AN
AUTHORISED SERVICE CENTRE TO PREVENT ALL RISKS.
