INSTALLER SECTION
1.2 Reception of the appliance
After removing the packing, ensure that the appliance has not been damaged in transport. If it has, inform
the retailer. If safety has been compromised, do not install the machine.
Double check the fi rm tightness of all hose-clamps on piping, nuts and bolts, and fasteners, that
might come loose with the transport, to prevent water dripping or leakages, or other damages,
during the machine's operation.
For disposal of the packing, see chap.

.
1.3 Water 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 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 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 (see par.
5.5
).
All damages caused by the hydraulic limestone (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.
Machines shall be made with extra power in case of cold water infeed.
Each machine is provided with a rubber tube with a ¾" threaded attachment for water fi lling.
Connect the emptying tube, supplied with the appliance, to the union elbow located under the tub so that water fl ows 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 Directive 98/83/EC.
The inlet water must also meet the parameters given in the table 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 softner 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
Desired value: Out of range values might lead stainless steel blackening/tarnishing.
It is recommended a water test once a year.
