5PREPARING THE APPLIANCE FOR USE
Convey the dishwasher to the installation site, remove the packaging and check the appliance and
components for damage; any damage found must be reported to the transporter in writing. The
packagingcomponents(plasticbags,expandedpolystyrene,nails,etc.)mustnotbe leftwithinreach
of children and pets since they are potentially dangerous. All packaging materials used are
environment-friendly. They can be kept without constituting any hazard, or may be disposed of at
a specialist waste disposal centre. The plastic components suitable for recycling are marked as
follows:
PE -polyethylene: externalpackaging film, bag containing the instructions, protective bags.
PP - polypropylene: straps used to close the packaging.
PS -expanded polystyrene: cornerguards, top of packaging.
Wooden and cardboard components can be disposed of in accordance with the local regulations.
5.1 Positioning and installation
Place the dishwasher in the chosen point and remove the protective film. Level the dishwasher
(with the aid of a spirit level) on its four feet, adjusting them to ensure that it is stable. If the
dishwasher is installed above the ground, make sure that the stand and dishwasher are secured
properly and do not constitute a hazard.
All operations described in this section must be carried out and/or checked by the
qualified staff who install and commission the dishwasher.
The systems and premises in which the dishwasher is installed must comply with the
relevant regulations.
If the dishwasher is installed next to another appliance, also check the
recommendations provided by the manufacturer of the adjacent appliance.
Installations other than those described must first be approved by the manufacturer.
Use only professional furnishings and units in the vicinity of the dishwasher. Any
other types of furnishing may be damaged.

14
5.2 Connection to the water supply
Check that the intake water pressure, flow rate and temperature are as stated in the dishwasher's
technical characteristics. If the dynamic pressure exceeds the limit stated in
the technical characteristics, a pressure reducer must be installed. If the
pressure is lower, it might be necessary to fit a special pump to ensure
optimal performance. Connect the water intake hose to a connector with ¾”
gas threaded fitting, inserting the filter "A" provided. The tap must be easily
accessible after installation of the appliance.
5.3 Drain connection
The dishwasher is fitted with a drain pump and can operate with drain connections on the floor or
wall. Before connecting the hose, check that the diameter and height of the wall drain connection
are as stated in the dishwasher's technical characteristics. When connecting the dishwasher's
drain hose, take care to avoid kinks, sharp bends orcrushing. Since the drain water temperature
can be very high, the end of the drain hose must be fixed to the drain connection using the hose
clamps provided.
Only use new hoses for connection to the water supply. Old hoses or hoses salvaged
from previous installations must not be used.
If the water supply system has been unused for a long time or if work has been done
on it, before connecting the appliance's intake hose run the water to flush the air
and dirt from the pipes.
FOR MODELS WITH A WATER SOFTENER
An “approved” double check valve or some other noless 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 drain connection must be made in accordance with the relevant national
regulations. Substandard connections may cause flowback and in some cases
pollution.
No extensions must be added to the drain hose supplied with the appliance. Any
extensions might cause drainage problems.

15
5.4 Connection to the electricity supply
The dishwasher 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 provided with the appliance. The dishwasher's rated electrical characteristics are
provided on its technical data plate. A circuit breaker with contact gap rated for category II
overvoltage and an overcurrent protection device (magnetothermal switch or fuses) must be
installed in an easily accessible position on the dishwasher's power supply line. These devices must
only serve the dishwasher and must be suitable for its rated electrical characteristics. The
electrical protection devices must undergo a functional test before the dishwasher is put into
operation. If the dishwasher is connected to the electrical mains by means of a plug, it must be of
the same type as the power socket, suitable for the appliance's rated electrical characteristics and
compliant with the relevant national regulations. The power plug must be easily accessible after
the appliance has been installed.
Electrical safety is only ensured if the dishwasher is connected to an earth conductor
compliant with the relevant electrical regulations. If in doubt, have the system
inspected by a qualified electrician.
Donot connect the dishwasher tothe electrical mains by means of adapters or
extensions,since they may cause dangerous overheating.
Connect the appliance to the earth system. The earth connection terminal is low
down on the back of the appliance and is marked with the symbol.
The dishwasher is always powered up unless the master switch is turned off or, on
appliances with power plug, the plug is disconnected.

16
6FIRST START-UP
6.1 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 qualified staff, who will start it up for the first
time and provide the relevant operating instructions.
6.2 Preparing for use ( Important )
The rinse aid dispenser is fitted onall 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 appliance 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 thefilters onto their ends as shown. If the detergent dispenser is not
factory-fitted, it can be retrofitted after ordering the relative kit.
6.3 Using the water softener (on models with this feature only)
The quantity of lime in the water (which indicates its hardness) causes
whitish marks on dry dishes and dishes alsotend to lose their shine over
time. The dishwasher is equipped with an automatic water softener which
removes the substances that cause hardness from the water with the aid of
regenerating salt.
The first time the dishwasher is used, a litre of water must be poured into the
tank with the salt. Whenever the tank is filled, always take care to ensure that
the cap is firmly closed. The mixture of water and detergent must not get into
the salt tank, as this would impair operation of the regeneration system. In
this case warranty cover will be forfeited.
IMPORTANT:
Wheneverthetypeofdetergentorrinseaidis changed,itisABSOLUTELYESSENTIALtoflushout
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 professionaldishwasher. Failure to comply
with this recommendation leads to forfeiture of the warranty entitlement on the appliance’s
watersystem.Replacementoftheinternal tubeofthe detergentandrinseaidperistalticpumps
