INSTALLER SECTION
2.3 Electrical connection
The electrical connection must be made according to current technical standards.
Ensure that the mains voltage corresponds to the value given on the machine dataplate.
Install a suitable omnipolar thermal magnetic circuit breaker, dimensioned according to absorption, with opening contact,
in according to current standards.
This circuit breaker must be exclusively used for this purpose and installed in the immediate vicinity.
The machine must be turned off with this switch.
Make sure that the electrical systems are suitably earthed.
On the back of the appliance there is a terminal marked with the symbol
which is provided for equipotential connection
between different appliances. The special dataplate gives the max. power value in watts (W), amperes (A) and fuse, for
dimensioning of the line, cable and switches.
The dealer/importer/installer must adapt the power cable insulation class according to the work environment, in
conformity with current Technical Standards.
Cable characteristics:
Use copper cables only, correctly dimensioned for the amperage indicated on the machine
and made to operate at minimum 167°F (75°C).
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 - see pict. 2). The problem does not exist if the pump is single-phase (standard).
2.4 Temperature adjustment
If necessary, the water temperature of the wash and rinse cycles can be adjusted by means the respective
thermostats.
The recommended temperatures are 160°F (71°C) for the wash cycle (tub) and 185°F (85°C) for the
rinse cycle (boiler).
2.5 Rinse aid dispenser operation
Technical characteristics:
Operation:
it utilizes the wash pump starting pressure and the water circuit pressure in the rinse phase. Min. water pressure
30 Psi (200 kPa).
Water connection:
1) Connect the dispenser tube fitting
A
to the pump, by means of the rubber tube installed in the appliance (pump pressure).
2) Connect the small black rubber tube by the brass delivery fitting
B
to the connection near the boiler (injector).
3) Make sure that the green product suction tube is inserted on the special fitting
C
and that the small filter and the ballast
are inserted 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 2 cubic inches (from 0 to 4
cm
3
), equivalent to a length of 0 to 11 inches (from 0 to 30 cm).
Min. delivery is obtained by turning the adjustment screw
D
clockwise all the way, whereas max. delivery is obtained by
turning the adjustment screw approx. 20 turns anticlockwise.
For the right amount of product see the paragraph
Rinse aid use
.
Note:
for every turn of the screw the amount of rinse aid drawn in the tube varies by 5/8 inches (1,6 cm) equal to 13/16 cubic
inches/run (0,2 cm
3
/turn - approx 0,01 onces/run - 0,21 gr/turn with rinse aid density of 0,60 onces/cubic inches - 1,05 g/cm
3
).
The rinse aid dispenser cannot work correctly if the difference in level between the bottom of the machine and the tank is
more than 31 inches (80 cm).
THE DISPENSERS ARE PRESET FOR DRAWING 2" (5 cm) FOLLOWING A FUNCTIONAL CHECK DURING THE TESTING
PHASE. THIS VALUE MUST ALWAYS BE MODIFIED ACCORDING TO THE TYPE OF RINSE AID AND THE HARDNESS
OF THE WATER.
