INSTALLER SECTION

1. MACHINE INSTALLATION

1.1 RECEPTION OF THE APPLIANCE
After removing the packing, ensure that the appliance has

not been dam­aged in transport. If it has, inform the retailer. If safety has been compro­mised, do not install the machine.

Double check the firm tightness of all hose-clamps on

piping, nuts and

bolts, and fasteners, that might come loose

with the transport, to prevent
water dripping or leakages, or other damages, during the machine's
operation.

For disposal of the packing, see chap. 8.

ATTENTION:

At the end of installation make sure to remove the parts of this booklet
relevant to the installer, for future consultation.

1.2 WATER CONNECTION

Connect the machine's water supply with an interrupt valve

capable of
quickly and completely shutting off water intake.
Make sure that the water supply pressure comes within the values given
in the Table 1.
If it is less than 2 bar dynamic pressure (200 kPa) an external

pressure
pump must be installed to guarantee optimal machine operation.
If, however, the water supply pressure is greater than 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.
Note: All damages caused by the hydraulic limestone (calcareous water
higher-up than 10°F and without watersoftner) are not are not covered
by warranty.
In order to ensure the optimum performance, the water supply temper­ature must come within the range given in table 1.
Each machine is provided with a rubber tube with a ¾" threaded attach­ment for water filling.
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 leve

l 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.

table 1

Pressure Table Min Max
Static Pressure 250 Kpa 400 Kpa
Dynamic Pressure 200 Kpa 350 Kpa
Water hardness 2°f 10°f
Hot water-supply temperature 5°C ≤ t < 50°C 50°C≤ t ≤ 60°C

1.4 TEMPERATURE ADJUSTMENT
If necessary, the water temperature of the wash and rinse cycles can be
adjusted by means of the fine-adjustment screws on the respective ther­mostats.
The recommended temperatures are 55°C for the wash cycle (tub) and
85-90°C for the rinse cycle (boiler).
Machines with boiler inside the washing tub have only one thermostat
which should be set at 75-80°C.

1.3 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.

A suitable omni-polar, one-way switch shall be installed and sized accord­ing

to the absorption provided, with a contact opening of at least 3 mm.
This switch shall be solely and exclusively used for this purpose and
installed in the immediate vicinity of the machine.
Make sure that the facility is equipped with efficient ground connection.
WARNING: check very carefully if the “ground connection” of the machine,

is properly sized and fully efficient, 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.

The machine has a connection at the back, indicated by the symbol ,
that is meant to link the steel structure and masses among different
apparatuses.
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.

1.5 RINSE AID DISPENSER OPERATION

Technical characteristics
Operation: It utilizes the difference in combined pressure caused by turn-

ing the washing pump on and off, and the rinse pressure.

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 in 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 tub.

Priming:

To prime the dispenser, turn on the appliance and carry out several com­plete wash cycles or press the adjustment screw (D) during the wash
cycle and open and close the door combined with pressing the pin (D).
This method speeds up the refill process.

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.
In order to regulate the dispenser to the minimum amount, turn the ad­justment screw (D) completely clockwise. For the maximum amount, turn
the screw anticlockwise about 20 complete turns.
For the correct amount of rinse aid, see the paragraph 5.2 Use of rinse aid.
Note: for each turn of the screw the amount of the product drawn into
the tube varies by 1.6 cm, equivalent to 0.2 cc/turn (about 0.21g/turn with
a concentration of 1.05 g/cm³ of rinse aid). The rinse aid cannot function
properly if the difference in level between the bottom of the machine and
the container exceeds 80 cm.
THE DISPENSERS ARE PRE-SET TO A 5 CM OF TUBE (0,65 gr.) INTAKE
OF PRODUCT FOLLOWING A TEST PHASE SYSTEM CHECK. THIS MEAS­UREMENT SHOULD BE ADJUSTED ACCORDING TO THE TYPE OF RINSE
AID USED AND WATER HARDNESS.

2.1 ELECTRICAL CONNECTION
Follow the wiring diagram attached to the machine.

2.2 WATER CONNECTION
a) A Ø 12 hole must be made on the back of the ap-

pliance. In some appliances the hole has already
been made and is closed with a plastic cap.
Remove the cap from the hole and fi t the delivery
connection.

b) Otherwise, drill one of the same diameter as the

injector on the back part of the tub (see image 4).
This operation must be carried out by the Technical
Service.
The hole must be made above the water level.
Important: make the hole in a position distant from
the overflow tube, so that detergent does not flow
out immediately. Fix the dispenser in a vertical

position with tube connectors turned downwards,
making sure not to place it on energized components.
Clean the inside of the machine from any drilling
residual.

c) Correctly mount the injector "C" using the appro-

priate fi xtures.

d)

Connect the suction tube to the suction attachment
of the dispenser (see image 4 point "A").

e) Connect the delivery tube to the other attachment

of the dispenser, and the delivery fitting (see image
4 point "B").

f)

Insert the suction tube with fi lter in the detergent tub.

g) Prime the detergent and proceed to dispense.

2.3 DISPENSING THE DETERGENT
The detergent dispenser capacity can be adjusted
using a screwdriver as shown in pict 3.
Every 2 cm of product drawn into the tube corre-

sponds to 0.25 cm³ equivalent to 0.3 g (with a con­centration of 1.2g/cm³). For proper dispensing see
paragraph 5.1.
