1.3 Electrical connection
Electrical connection must be carried out in compliance with current standards.
Make sure the line voltage matches that given on the special machine dataplate. An
omnipolar thermal magnetic switch with contact breaking distance of at least 3 mm and
adequate for the absorption must be installed.
The switch must be used only and exclusively for this use and installed in the immediate
vicinity. The machine must be turned off with this switch.
Ensure that the system has an efficient earth.
On the back of the machine there is also a terminal marked by the symbol (see fig.1)
usedforthe equipotential connectionbetweendifferentappliances. The specialdataplate
gives the max. power value in watts (W) and amperes (A), for dimensioning of the line,
cable and switches.
N.B.: for machines with 400Vac3N, H05RN-F or H07RN-F type cables
mustbeused,orreplacethemwithothersifdifferentfromthestandards
in the country where the dishwasher is installed. The dealer/importer/
installer must adapt the power cable insulation class according to the
work environment, in conformity with current Technical Standards.
Warning: some versions of this machine can dissipate more than 10mA to earth.
If the machine is fitted with a three-phase pump, check correct motor rotation (direction
of arrows on the casing). The problem does not exist if the pump is single-phase
(standard).
1.4 Rinse aid dispenser operation
Technical specifications:
Operation:
Phase 1 - it utilizes the wash pump starting pressure and the water circuit pressure in
the rinse phase (phase 1: injects the product in boiler; phase 2: draws from the tank).
Min. water pressure 200 kPa.
Water connection:
1) Connect the dispenser by its hose holder fitting (A) to the pump, by means of the
rubber hose installed in the machine (pump pressure).
2) Connect the black rubber tube by its delivery connection (B) to the union located near
the boiler (injector).
3) Ensure insertion of the green product suction tube in the special connection (C) and
the filter and ballast in the rinse aid tank.
Priming:
To carry out priming, start the machine and carry out a few complete wash and rinse
cycles. To speed up restoration, press the adjustment screw (D) during the wash cycle
and open the hood; press pin (D) again and close the hood; press pin (D) again and
close the hood for a few seconds, open the hood again and press pin (D) again and
close the hood. Repeat this operation until the green tube is completely filled.
Adjustment:
With every rinse the dispenser draws a quantity of rinse aid adjustable from 0 to 4 cm3
equivalent to a length of 0 to 30 cm drawn in the tube.
Min.delivery is obtainedbyturning theadjustmentscrew Dclockwiseall the way,whereas
max.deliveryis obtained by turning the adjustmentscrewapprox.20 turns anticlockwise.
For the right amount of product see the paragraph “Rinse aid use”.
N.B.: for every turn of the screw the amount of rinse aid drawn in the tube varies by 1.6
cm, equal to 0.2 cm³/turn (approx. 0.21g/turn with rinse aid density of 1.05 g/cm³).
The rinse aid dispenser cannot work correctly if the difference in level between the
bottom of the machine and the tank is more than 80 cm.
