2. MACHINE INSTALLATION
2.1 Receiving the machine
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.
Double check the firm tightness of all hose-clamps on piping, nuts, bolts and electrical connection
that might have come loose during transportation, to prevent water dripping leakages, or other
damages, during the machine operation.

for disposing the packing material.
2.2 Water connections
Connect the machine's water supply with an interrupt valve capable of quickly and completely shutting off water intake.
The Water system must have characteristics between the parameters specified in table 1.
If it is less than 30 Psi dynamic pressure (200kPa) a pressure pump must be installed to guarantee optimal machine operation.
If, however, the water supply pressure is greater than 60 Psi (400 kPa), a pressure reducing device must be installed.
For water with average hardness greater than 10°f, a water softener must be used. This will result in cleaner dishes and
longer life of the appliance.
Each machine is provided with a rubber tube with a ¾" threaded attachment for water filling.
It is advisable to connect the hose to a water supply not above 150°F (65,5°C), if connected to the hot water.
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.
