5. Installation
5-1.Positioning the appliance
Positioning the appliance in the desired location. The back of the appliance should rest against
the wall, 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.
5-2.Leveling the appliance
Once the appliance is positioned, adjust the feet (screwing them in or out) to adjust the
dishwasher, making it level. The appliance should not be inclined more than 2°. If the appliance is
level, it will help ensure proper performance.
5-3.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).
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.
fig.A
Warning
The appliance is to be connected to the water mains
using new hose-sets and that old hose-sets should not
be reused.
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.
fig.B
WARNING:HAZARDOUS VOLTAGE!
Under no circumstance should the water inlet hose be cut as it contains live electrical parts.
5-4.Anti-Flooding protection
The dishwasher is equipped with a system that stops the supply of water in the event of a problem
with the water supply hose, or leaks within the unit, in order to prevent damage to your home. If
for any reason the box containing the electrical components happens to get damaged, turn off the
power supply and remove the plug for the appliance from the socket immediately. In order to
guarantee that the anti-flooding feature operates properly, the "A" box with water supply hose
must be attached to the water supply tap as shown in fig.B. No other type of connection is
acceptable.The water supply hose must not, under any circumstances, be cut,as it contains

electrical parts which are live. If the length of the hose is not adequate to make a proper
connection, the hose must be replaced with one which is long enough. This hose is available
upon request from specialised retailers and approved service center.
5-5.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 siphon trap (U-bend) with a
connecting piece for the electrical 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.

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.

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
