4 INSTALLATION INSTRUCTIONS FOR THE AFTER-SALES SERVICE
4.1 Water connection
Water supply and drain connection:
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 Aprovided (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 2 and 7 bar; if it is higher a pressure reducer must be
installed. If the pressure is less than 2 bar it might be necessary to fit a special pump on the appliance.
Contact the After-Sales Service.
It is essential to fit a main stop tap on the water intake 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)
Caution: make sure that the intake and drain hoses are not bent, constricted or crushed after
installation.
If the drain connection is to an outlet with valve, the maximum height of the drain is reduced to 600 mm.
In all cases, after installation check that the drain is fully functional by pumping out the tank completely (P0
cycle).

7
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
machine’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..
IN THE EVENT OF DAMAGE TO THE SUPPLY CORD, HAVE IT REPLACED BY THE MANUFACTURER
OR AN AUTHORIZED TECHNICAL SERVICE CENTRE IN ORDER TO AVOID ANY RISK.

5 START-UP
FIRST START-UP
The electrical protection system must undergo a functional test before the appliance is put into operation.
The appliance must be installed and/or inspected by the qualified staff, who will start it up for the first time and
provide the relevant operating instructions.
PREPARING FOR USE
Important:
The rinse aid dispenser is fitted on all models, the detergent dispenser only on some.
If both dispensers are present put the external detergent and rinse aid containers in
place and insert the respective intake hoses on the rear of the machine into them.
Red hose: detergent
blue hose: rinse aid
Before inserting the hoses into the containers, fit the weights (needed to ensure that
they always draw in liquid from the bottoms of the containers) and the filters onto their
ends as shown.
If the detergent dispenser is not factory-fitted, it can be by ordering the relative kit.
As an alternative an external dispenser can be fitted, making the electrical connection by means of an H05 RN-
F 2x0.5 mm electrical cable, which can be laid along the route shown in the TECHNICAL DATA diagram and
connected as shown in the wiring diagram supplied with the dishwasher.
The dispenser must operate on 230V/50 Hz with maximum power absorption of 15 W.
Connect to the detergent dispenser outside the dishwasher using the red hose mentioned above.
IMPORTANT:
Whenever the type of detergent or rinse aid is changed, it is ABSOLUTELY ESSENTIAL to flush out the
peristaltic pumps by placing the external intake pipes in water for a few cycles.
Always use only products specifically recommended for use in a dishwasher.
The internal pipes of the detergent and rinse paid pumps should be replaced by the After-Sales Service
every 12 months or 15,000 wash cycles.
Failure to comply with this recommendation leads to forfeiture of the warranty entitlement on the
appliance’s water system.

10MAINTENANCE AND CLEANING
Although no particular scheduled maintenance is required, users are advised to have the dishwasher checked by a
specialist technician twice a year.
N.B.: the manufacturer accepts no liability for wilful damage or damage deriving from carelessness, neglect, failure
to comply with instructions, regulations and standards or incorrect connections.
9.2 Daily cleaning
The dishwasher has IPX4 protection, but the use of direct water jets for cleaning is forbidden.
Cleaning the filter during th day
Remove the filters (simply lift them out as shown here), taking care that
no large residues fall into the sump underneath.
Clean them to remove residues and rinse with plenty of water, then put
them correctly back in place; do not use sharp or pointed tools.
Clean away any limescale deposits to prevent excessive build-ups;
‐If possible, leave the door ajar when not in use;
‐Clean surfaces thoroughly and often with a damp cloth; use
neutral, non-abrasive detergents which do not use chlorine
compounds, which corrode and damage stainless steel.
Do not use the products mentioned above even when cleaning the floor underneath or in the vicinity of the
dishwasher, to ensure that fumes or drops cannot damage the steel surfaces.
IMPORTANT: The dishwasher automatically performs program “P0” at the start of the day if water has been
left in the tank and has dropped below the temperature of 40°C
9.3 Periodic checks
Remove the top and bottom spray arms by unscrewing the central screw and unscrew the caps from the ends of
the rinsing arms as shown. Do not unscrew the nozzles.

Clean the outside of the appliance with a damp cloth and neutral soap, rinsing and drying thoroughly.
9.4 Lengthy periods out of use
If the dishwasher is to be out of use for a fairly long period of time, the detergent and rinse aid dispenser
devices must be emptied to prevent crystallisation and damage to the pumps: Remove the intake hoses
from the detergent and rinse aid containers and place them in a container of clean water, then perform a few wash
cycles followed by a complete pump-out.
Finally, turn off the master switch, close the water intake valve and leave the door ajar until the interior is
completely dry. The detergent and rinse aid intake hoses must be put back into the containers when the
dishwasher is returned to service, taking care not to swap them over (red hose = detergent, blue hose = rinse
aid).
