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 packaging
components (plastic bags, expanded polystyrene, nails, etc.) must not be left within reach 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: external packaging film, bag containing the instructions, protective bags.
PP - polypropylene: straps used to close the packaging.
PS -expanded polystyrene: corner guards, 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 (withthe
aid of a spirit level) on its four feet, adjusting them to ensurethat it is stable. If the dishwasher is installed
above the ground, make sure that the stand and dishwasher are secured properly and do not constitutea
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.

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 ensureoptimal
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 or crushing. Since the drain water temperature can be very high, the end ofthe
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.
To run the beer cycle, only present on some models (see programs table), a cold water
supply is required. This increases the washing times forall programs.
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 areprovided 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 bymeans ofa 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 afterthe
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.

6FIRST START-UP
6.1 First start-up
The electrical protection system must undergo afunctional test before theappliance is put into operation.
The appliance must be installed and/or inspected by qualified staff, who will start it up for the firsttime
and provide the relevant operating instructions.
6.2 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 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 the filters
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 also tend to lose their shine overtime. 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 theregeneration system. In this case warranty cover
will be forfeited.
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 professional dishwasher. Failure to comply with this
recommendation leads to forfeiture of the warranty entitlement on the appliance’s water system.
