1.2 Reception of the appliance
Before accepting the machine, verify that all the data on the data-plate corresponds to the
required ones and to the ones of the available electrical supply (see paragr. 1.1 Dataplate).
After unpacking, make sure the machine has not been damaged during transportation. If so, do
notify the seller immediately about the problem. If the damage might question the machine safety,
do not install it.
The installation and the starting of the machine must be carried out by trained operators only,
even if the machine is coming from another site and it has been used, already.
For disposal of the packing see chap. 7. ENVIRONMENTAL ASPECTS.
1.3 Hydraulic connection
Connect the machine's water supply with an interrupt valve capable of quickly and completely shutting off water intake. Make
sure that the water supply pressure comes within the values given in the table Tab. 1. If it is less than 2 bar dynamic pressure
(200 kPa) a pressure pump must be installed to guarantee optimal machine operation (by request, the dishwasher can be
supplied with a pump). If, however, the water supply pressure is greater than 4 bar (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. By request, the machine can be equipped with a water softener
If the machine is equipped with a water-softener, a regeneration of the resins shall be done on regular basis. In machines
equipped with optional regeneration device it is advisable to use water at a temperature not above 40 °C, so as not to alter the
characteristics of the resins.
Note: Any damage caused by limestone (calcareous water higher-up than 8 °f and without water-softener) will not be covered
by warranty.
In order to ensure the optimum performance, the water supply temperature must come within the range given in table Tab. 1.
Machines shall be made with extra power in case of cold water infeed.
Each machine is provided with a rubber tube with a 3/4” threaded attachment for water filling.
Connect the emptying tube, supplied with the appliance, 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.

1.3.1 Water supply characteristics
The machine water supply must be potable, in compliance with the legislation in force.
The inlet water must also meet the parameters given in the table Tab. 2.

1
Out of range values might lead to corrosion and jeopardize the life of the machine.
2
Should the water hardness is higher it is compulsory to install a water softener and check periodically its operation.
3
Out of range values might lead scaling and sediments with a consequent lower performance, functionality, and expected life
of the machine.
4
4 Desired value: Out of range values might lead stainless steel blackening/tarnishing.
It is recommended a water test once a year.
