1.4 Electrical connection
The electrical connection shall be carried out by qualifi ed personnel, in accordance to the local laws in force.
Make sure that the supply voltage is the same as written on the machine plate.
On the back of the appliance there is a terminal marked with the symbol , which is provided for equipotential
connection between diff erent appliances (see electrical safety standards).
The machine’s sound level is LpA = 70dBA ± 2.5. **
**test made according to EN 60335-2-58/A11
1.5 Temperature adjustment
If necessary, the water temperature of the wash and rinse cycles can be adjusted by means of the fi ne-adjustment
screws on the respective thermostats.
The recommended temperatures are 55-60°C for the wash cycle (sump) and 85-90°C for the rinse cycle (boiler).
1.6 Rinse aid dispenser operation
Operation: The dispenser utilizes the pressure gap determined by the functioning of the
wash pump, and the pressure of the water supply.
Hydraulic connection (for replacement only):
1) Connect the dispenser hose connection A to the pump, by means of the rubber hose
installed in the wash pump’s delivery side.
2) Connect the black rubber hose from the hose connection B to the connection on the
boiler (injector).
3) Make sure that the green suction tube is inserted on the connection C and that the small
fi lter and the ballast are properly inserted in the rinse aid tank.
Priming: To prime the dispenser, turn ON the appliance and run some complete wash cycles.
Adjustment: With each rinse cycle, the dispenser draws an amount of rinse aid, adjustable from 0 to 4 cc, equivalent to a
length of 0 to 30 cm drawn into the suction tube.
To reduce the fl ow turn the adjustment screw D completely clockwise. For the maximum amount, turn the screw anticlockwise
(about 20 complete turns).

IMPORTANT: connect that clamp to other appliances.
To dimension supply cables and switches, please refer to the maximum power expressed in Watts (W) and
Amperes (A) specifi ed on the machine serial number plate.
FOR APPLIANCES USING A THREE-PHASE POWER SUPPLY, FOLLOW THE INSTRUCTIONS AND WIRING
DIAGRAM ATTACHED TO THE APPLIANCE.
Main supply cable: The installation engineer must adapt the main supply cable isolation class to the actual
working environment, in accordance with the local Technical Regulations.
WARNING: check very carefully if the “ground connection” of the machine, is properly sized and fully effi cient,
and that not too many units are connected on it. An undersized or poor “ground connection” might lead to
corrosion and/or pitting eff ect on the stainless steel plates, even to perforation.
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 “category III”
overvoltage conditions.
This switch shall be included in the power network solely and exclusively used for this purpose and
installed in the immediate vicinity of the machine.
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 effi cient ground connection.
