INSTALLER SECTION
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 effect on the stainless steel plates, even to perforation.
Moreover, the machine has a clamp at the back indicated by the symbol
used as equipotent connection among different apparatuses (see electrical safety
standards).
IMPORTANT: connect the 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 INSTRUC-
TIONS AND WIRING DIAGRAM ATTACHED TO THE APPLIANCE.
PAY ATTENTION TO THE CORRECT PUMPS ROTATION, IN CASE OF THREE-PHASE
SUPPLY.
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.

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).

Rinse aid dispenser operation (image 1 - 2)
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
installed in the wash pump's delivery side.
2) Connect the black rubber hose from the hose connection
boiler (injector).
3) Make sure that the green suction tube is inserted on the connection
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
amount, turn the screw anticlockwise (about 20 complete turns).
For proper chemical product dosage see the chemical-product manufacturer recommen-
dations (see also par. 5.2).
N.B.:
for each screw rotation the rinse product dosage varies by 1,6 cm pulled into the hose,
equal to 0,2 cc/rotation (about 0,21 g/rotation with product density of 1,05 g/cc).
The rinse aid dispenser cannot function properly if there is a slope of over 80 cm between
the bottom of the machine and the canister.
THE DISPENSERS ARE PRE-CALIBRATED AT A SUCTION OF 5 CM OF TUBE (0,65 gr.)
FOLLOWING OPERATIONAL VERIFICATION AND INSPECTION. THIS PARAMETER
SHALL BE MODIFIED UPON RINSE-AID TYPE AND WATER HARDNESS.

Peristaltic rinse aid dispenser operation (optional - image 3)
Operation: The rinse aid dispenser is a peristaltic pump.
The rinse aid dispenser is also activated when the tank is loaded.
Water connection:
Make sure that the green product suction tube is inserted on the special
fi tting
