Connect the machine’s water supply with an inter-
rupt valve capable of quickly and completely shut-
ting off water intake.
Make sure that the water supply pressure comes
within the values given in the Table 1.
If it is less than 2 bar dynamic pressure (200 kPa)
an external pressure pump must be installed to
guarantee optimal machine operation.
If, however, the water supply pressure is greater
than 400 kPa, a pressure reducing device must be
installed.
For water with average hardness greater than 8°f.,
a water softener must be used. This will result in
cleaner dishes and longer life of the appliance.
Note: All damages caused by the hydraulic lime-
stone (calcareous water higher-up than 8°f and
without watersoftner) are not are not covered by
warranty.
In order to ensure the optimum performance, the
water supply temperature must come within the
range given in table 1.
Each machine is provided with a rubber tube with
a ¾” threaded attachment for water filling.
Connect the emptying tube, supplied with the ap-
pliance, to the union elbow located under the tub
so that water flows freely. If it is not possible to
empty the water at a level lower than the drain of
the appliance, it is advisable to install an emptying
pump, which can be provided by request.
The emptying tube should always be connected to
a siphon to prevent odor back-up from the screen.
1.3 ELECTRICAL CONNECTION
The electrical connection must be made accord-
ing to current technical standards. Ensure that the
mains voltage corresponds to the value given on
the machine dataplate.
A suitable omni-polar one-way switch shall be
installed and sized according to the absorption
provided, in order to completely guarantee the
disconnection from the supply mains, under “cat-
egory III” overvoltage conditions.
This switch shall be included in the power net-
work solely and exclusively used for this purpose
and installed in the immediate vicinity of the ma-
chine. Always turn the machine off via this switch.
This is the only model of switch that guarantees
a total electrical power disconnection.
Make sure that the facility is equipped with
efficient ground connection.
WARNING: check very carefully if the “ground con-
nection” of the machine, is properly sized and fully
efficient, and that not too many units are connected
on it. An undersized or poor “ground connection”
might lead to corrosion and/or pitting effect on the
stainless steel plates, even to perforation.
On the back of the appliance there is a terminal
marked with the symbol , which is provided for
equipotential connection between different ap-
pliances (see electrical safety standards).
Feed cable: the retailer - importer - installer must
ensure that the feed cable complies with the cable
insulation category of the workplace, in conformity
with current Technical Standards.
