2. Installation and hook-up
Remove the polystyrene basket retainers.
Position the appliance in the desired place of installation. The back or sides of the dishwasher may
be placed up against walls or other furniture units.
If the dishwasher is installed near a heat source, fit the special insulating panel to prevent
overheating and malfunction of the appliance.
To ensure stability, install integrated or built-under dishwashers only under continuous worktops,
and screw them to the adjacent units.
To facilitate the installation procedure, the intake and drain hoses can be positioned in any
direction; make sure that the hoses are not kinked, crushed or pulled too tightly.
Level the appliance on the floor using its adjustable feet. This operation is essential for ensuring
correct operation of the dishwasher.
Some models are equipped with only one adjustable foot at the rear, which can be adjusted by
turning the screw on the lower front part of the appliance.
2.1 Water supply connection
Preventing the risk of clogging or damage: if the water pipe is new or has not been used for a
long time, before connecting to the water supply check that the water is clear and free of impurities,
to prevent damage to the appliance.
The dishwasher must always be connected to the water system with new hoses; old or used hoses
must never be reused.
CONNECTING TO THE WATER SUPPLY
Connect the intake hose to a cold water supply with 3/4” gas thread, inserting the filter Asupplied
with the dishwasher.
Take care to screw the hose firmly into place with your hands and then complete by
tightening about 1/4 of a turn with pliers. In dishwashers equipped with the ACQUASTOP
device, the filters is already fitted inside the threaded ring.
The dishwasher can also be connected to a hot water supply not exceeding 60°C. Supplying the
appliance with hot water cuts down the washing time by approximately 20 minutes, but slightly
reduces its effectiveness. Make the connection to the domestic hot water supply using the same
procedure described for connecting to the cold water supply.

Installation instructions
29
DRAIN CONNECTION
Insert the dishwasher’s drain hose into a drain pipe
having a diameter of at least 4 cm, or alternatively,
place it inside the kitchen sink using the plastic support
provided, taking care not to crush or excessively bend
the hose. It is important to prevent the hose from
coming loose and falling. For this purpose, the plastic
support is equipped with a hole for tying it to the wall or
water tap.
The free end should be positioned at a height of
between 30 and 100 cm, and should never be
submerged in water.
If a horizontal drain extension hose is used (for a
maximum of 3 m) the drain hose can be placed at a
maximum height of 85 cm from the ground.
2.2 Electrical connection
Plug the power cord into a suitable electrical outlet, according to the instructions given in chapter
"1. Safety and operating instructions".
