3. Safety precaution

3-1.At time of delivery

Check packaging and dishwasher immediately for signs of transport damage. If the appliance is

damaged, do not put it into use but contact your supplier or customer service without delay.

Please dispose of packaging materials properly.

3-2.During installation

Site the dishwasher and connect it up in accordance with the installation instructions.

The dishwasher must not be connected to the electricity supply while installation is being carried

out.

Ensure that the domestic wiring is properly earthed.

The mains electricity supply must conform to the details shown on the dishwasher nameplate.

Do not connect the dishwasher to the electricity supply via an extension cable.

Built-under and built-in appliances should always be installed under a continuous work surface

which is attached to the adjacent cupboards, in order to ensure that the appliance is entirely

stable.

After the appliance has been installed, the mains plug should still be easily accessible.

Not on all models:

The plastic housing on the water inlet contains an electrically operated valve. The connecting

wires are inside the inlet hose. Do not cut through this hose and do not immerse the plastic

housing in water.

During installation, the power supply cord must not be excessively or dangerously bent or

flattened.

3-3.During normal use

The dishwasher must only be used by adults for the washing of household dishes and cooking

utensils.

This appliance cannot be installed outdoor, not even if the area in which it is installed is covered

by a roof; it is also very dangerous to leave it exposed to the rain and elements.

Do not place any heavy objects or stand on the door when it is open. The appliance could tip

forward.

The water inside the dishwasher is not suitable for drinking.

Do not use solvents of any kind inside your dishwasher. They could cause an explosion danger.

Open the door very carefully if the dishwasher is operating. There is a risk of water squirting out.

Do not touch the heating element during or after a wash cycle.

Fundamental rules to follow when using the appliance:

Never touch the dishwasher when barefoot or with wet hands or feet;

We discourage the use of extension cords and multiple sockets;

If the appliance is not operating properly or maintenance must be performed, disconnect the

appliance from the power supply.

4-4.Positioning the appliance

Positioning the appliance in the desired location. The back should rest against the wall behind it,

and the sides, along the adjacent cabinets or wall. The dishwasher is equipped with water supply

and drain hoses that can be positioned to the right or the left to facilitate proper installation.

4-5.Leveling the appliance

Once the appliance is positioned, adjust the feet (screwing them in or out) to adjust the

dishwasher, making it level. In any case, the appliance should not be inclined more than 2°. If the

appliance is level, it will help ensure proper performance.

4-6.Cold water connection

Connect the water supply hose to a threaded 3/4 (gas) connector,

making sure that it is fastened tightly in place (see fig.A).

Some models are fitted with an "Aquastop" water supply hose (see fig.B)

in which the small filter is already housed in the threaded end.

If the water pipes are new or have not been used for an extended period

of time, let the water run to make sure that the water is clear and free of impurities. If this

precaution is not taken, there is a risk that the water inlet can get blocked and damage the

appliance.

Warning

The appliance is to be connected to the water mains using new hose-sets and that old

hose-sets should not be reused.

4-7.Drain hose connection

Insert the drain hose into a drain pipe with a minimum diameter of 4cm, or let it run into the sink,

making sure to avoid bending or crimping it. If necessary, fit a syphon trap (U-bend) with a

connecting piece for the drain hose (fig.C). The free end of the hose must be at a height between

40 and 100 cm and must not be immersed in water.

Rev.

Attention:

The connecting piece for syphon trap (U-bend) must be securely fastened to the wall to

prevent the drain hose from moving and allowing water to spill outside the drain.

4-8.Electrical Connection

After making sure that the voltage and frequency values for the current in the home correspond to

those on the rating plate (located on the stainless steel inner door of the appliance) and that the

electrical system is correct for the maximum voltage on the rating plate, insert the plug into an

electrical socket which is earthed properly (the earthing of the appliance is a safety requirement

mandated by law).

If the electrical socket to which the appliance must be connected is not appropriate for the plug,

replace the whole cable, rather than using adaptors or the like as they could cause overheating

and burns.

Caution:

The dishwasher plug must be accessible even when the appliance is installed as a built-in

unit so that maintenance can be done safely.
