with explosion risk (ATEX).
Any accessories may only be installed on the appliance if authorised by the manufacturer.
Do not install the dishwasher next to appliances which irradiate strong heat (e.g. gas burners,
stoves, etc.) since they could cause damage.
If the dishwasher is installed above the ground, make sure that the stand and dishwasher are
secured properly and do not constitute a hazard.
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.
A circuit breaker and overcurrent protection device (magnetothermal switch or fuses) must
be installed in an easily accessible position on the dishwasher's power supply line. This
device must only serve the dishwasher and must be suitable for its rated electrical
characteristics.
Do not connect the dishwasher to the electrical mains by means of adapters or extensions,
since they do not guarantee the safety required.
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 on electrical systems. The power plug
must be easily accessible after the appliance has been installed.
Only use new hoses for connection to the water supply. Old hoses or hoses salvaged from
previous installations must not be used.
The drain connection must be made in accordance with the relevant national regulations.
Substandard connections may cause flowback and in some cases pollution.

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: 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 (withthe
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 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.

10
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 hoseclamps 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.
