1.2 Reception of the appliance
Before accepting the machine, verify that all the data on the data-plate corresponds to the
required ones and to the ones of the available electrical supply (see paragr. 1.1 Dataplate).
After unpacking, make sure the machine has not been damaged during transportation. If so, do
notify the seller immediately about the problem. If the damage might question the machine safety,
do not install it.
The installation and the starting of the machine must be carried out by trained operators only,
even if the machine is coming from another site and it has been used, already.
For disposal of the packing see chap. 7. ENVIRONMENTAL ASPECTS.
1.3 Hydraulic 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 Tab. 1. If it is less than 2 bar dynamic pressure
(200 kPa) a pressure pump must be installed to guarantee optimal machine operation (by request, the dishwasher can be
supplied with a pump). If, however, the water supply pressure is greater than 4 bar (400 kPa), a pressure reducing device must
be installed.
For water with average hardness greater than 8 °f, a water softener must be used. This will result in cleaner dishes and longer
life of the appliance. By request, the machine can be equipped with a water softener
If the machine is equipped with a water-softener, a regeneration of the resins shall be done on regular basis. In machines
equipped with optional regeneration device it is advisable to use water at a temperature not above 40 °C, so as not to alter the
characteristics of the resins.
Note: Any damage caused by limestone (calcareous water higher-up than 8 °f and without water-softener) will not be covered
by warranty.
In order to ensure the optimum performance, the water supply temperature must come within the range given in table Tab. 1.
Machines shall be made with extra power in case of cold water infeed.
Each machine is provided with a rubber tube with a 3/4” 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 level 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.

1Out of range values might lead to corrosion and jeopardize the life of the machine.
2Should the water hardness is higher it is compulsory to install a water softener and check periodically its operation.
3Out of range values might lead scaling and sediments with a consequent lower performance, functionality, and expected life
of the machine.
44 Desired value: Out of range values might lead stainless steel blackening/tarnishing.
It is recommended a water test once a year.
pag. 8

1.4 Electrical connection
Electrical connection must be carried out in compliance with the legislation in force and the relevant technical standards.
Make sure that the voltage is the same as reported on the data-plate.
It is necessary to install a suitable omni-polar automatic fuse switch sized according to the absorption that assures
the complete disconnection from the network in an overvoltage category III condition.
This switch must be incorporated in the supply network, dedicated only and exclusively to this circuit and installed in
the immediate vicinity.
The machine has to be absolutely turned off by this switch: only this switch gives the full warranty of complete
detachment from the electric network.
Make sure the appliance is linked to an efficient ground connection.
The machine is also provided with a terminal (marked with the symbol ) placed on the back end. It shall be used to
bond different appliances via the external bonding conductor, in order to avoid the risk of electric shock.
ATTENTION: Check very carefully if the “ground connection” of the machine is properly sized and fully
efficient, and that not too many units are connected to it. An undersized or poor “ground connection”
might lead to corrosion and/or pitting effect on the stainless steel plates, even to perforation.
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.

• Turn switch 0-1 to position 1(pressed). The operation is signalled by the switch indicator lighting up
or by the indicator with the symbol F1. The machine will automatically fill the tub with water (indicator
F2 when present will turn on, indicating the tub is full).
• Should the machines be equipped with the WRAS certified Break Tank, the tank filling phase is
extended.
• Then the heating phase begins. Indicator F5 comes on when the water temperature is reached.
• Insert the rack filled with dishes to wash. The plates must be correctly placed in the rack (see
paragr. 4.1 Cutlery and crockery loading).
• On machines with selector 3, select the wash cycle required (see chap. 3. CONTROL PANELAND
RELATIVE SYMBOLS).
• Before starting the wash-cycle, in absence of an automatic dosing system, pour the detergent in
the wash-tank.
• When the temperature indicator F5 will turn on, press the 1 START button for at least a second. The
beginning of the cycle is indicated either by the light on the button itself or on the F3 lamp.
• At the end of the washing cycle, a hot rinse cycle will take place.
• The indicator light of the 1 START or the F3 lamp will turn off when the cycle has finished (see chap.
3. CONTROL PANELAND RELATIVE SYMBOLS).
• Note:At cycle end with the door closed, dishes do not get dried Take out the baset or keep the door
open to allow the evaporation and the drying of the dishes. o carry out a cooling glasses cycle, on
appliances equipped with this option, press button 6and hold it down for the desired length of time
after the indicator light F3 goes off.After this cycle, the glasses remain wet (see chap. 3. CONTROL
PANELAND RELATIVE SYMBOLS).
• The appliance is now ready for a new wash.
• At the end of the day, clean the machine (see chap. 5. MAINTENANCE).
• Turn off the machine and the water tap.
• Turn off the main wall switch.
pag. 14

4.1 Cutlery and crockery loading
Before cutlery and crockery loading in the machine, coarsely clean them from the leftover food.
It isn't necessary to rinse the cutlery an crockery under water.
WARNING: Do not wash articles polluted with petrol, paint, chips of steel or iron, ash, sand, wax,
lubricant grease. These substances damage the machine. Do not wash fragile objects or material not
resistant to the washing process.
Pict. 3
Note the following recommendations:
• Crockery and cutlery should not be inserted inside one another, covering each other.
• Place the crockery in order to all surfaces can be reached by water; otherwise the dishes are not
washed.
• Make sure all the crockery are in a stable position and that the hollow containers don't overturn
(cups, glasses, bowls, etc.).
• Place in the rack all the hollow containers such as cups, glass, etc. upside-down.
• Place the crockery with deep hollow with upper face downwards, so that water can flow out.
• Make sure the smaller crockery do not fall from the rack.
• Check all the wash arms runs freely and they are not blocked by too tall or too prominent crockery.
Eventually, run a manual rotation of the arms to check it.
Some foods, such as carrots, tomatoes, and others, may contain some natural dyes substances, that in large amounts, can
alter the crockery and plastic parts colors.
Any discoloration does not mean that the plastic is not heat resistant.
Crockery and cutlery not suitable for dishwasher
Not suitable for dishwasher:
• Wooden crockery and cutlery or with wooden parts; water at high temperature causes deformation to wood. Also the
adhesives used are not suitable for treatment in the dishwasher; a consequence could be the handles detachment.
• Crafts, precious vases or decorated glasses.
• Not heat-resistant plastic crockery.
• Copper, brass, pewter or aluminum objects: they may become discolored or opaque.
• The decorations on glass, after a certain number of washes, can lose gloss.
• Fragile glasses or crystal items, if often washed, can become opaque.
We recommend to buy exclusively crockery and cutlery suitable for dishwashing.
After several washes, the glass can become opaque.
It is mandatory to repeat the washing cycle if at the end of the cycle the crockery are not well clean or if there are
washing residues (glasses, cups, bowls, etc. with liquid inside).
4.2 Use of detergent
By request the dishwasher can be equipped with an electric detergent dispenser (always recommended). If provided, the
machine will automatically take the needed detergent amount.
The detergent must be of good quality, of NON-FOAMING type, specific for the mechanical washing of dishes.
The use of liquid detergents is recommended.
The dosing has to be done following the recommendations of the detergent manufacturer and in accordance with the water and
dishes characteristics.
The detergent has to be inserted only in the wash tank. 1cm of the detergent drawn into the tube is equal to about 0,15 g. A
correct amount of detergent is very important for a successful wash.
Note: It is forbidden to use detergents with chlorine-based reagents.
pag. 15

4.3 Use of rinse aid
It is possible to use the rinse aid to get quicker drying and polishing.
The machine is equipped with a rinse aid dispenser. The machine automatically draws the rinse aid chemical.
The dosing has to be done following the recommendations of the rinse aid manufacturer and in accordance with the water
characteristics.
Note: Too much chemicals produces foam that reduces the effectiveness and lifetime of the washing pumps.
Too much chemicals might leave residuals on the dishes.
4.4 Regeneration device (optional)
Resin regeneration by the water softener is very important.
Resin regeneration: Resin regeneration should be carried out according to the number of cycles as indicated in the picture
below Ex.: 27 °f (or 15 °d) = 39 cycles.
To carry out the purifying cycle, follow these instructions:
•Open the water tap and plug in the main switch.
•Turn the main switch 2to 1 (ON) (see chap. 3. CONTROL PANELAND RELATIVE SYMBOLS).
•Open the door.
•Remove the overflow tube and empty all the water in the tub.
•Once the tank is empty check and fully replenish the salt, being careful not to spill it on the tank itself.A strong concentration
of salt can negatively affect the correct functioning and service life of the machine. Fill the special container, placed on the
inside of the tub, with coarse salt (1-2 mm. grains - the maximum capacity of the bowl is 500 g. - see Pict. 4).
•Close the door, press button 5for 5 seconds and wait for the cycle indicator F4 to light up (see chap. 3. CONTROL PANEL
AND RELATIVE SYMBOLS). The resins contained in the water softener will be automatically regenerated in about 20
minutes. The cycle is completed when the indicator light F4 goes off.
•Wait 20 seconds before opening the door.
•After the softening cycle, switch the machine OFF (button 2 - see chap. 3. CONTROL PANELAND RELATIVE SYMBOLS).
•Turn off the main wall switch.
Resin regeneration by the water softener is very important.
Resin regeneration: Resin regeneration should be carried out according to the number of cycles as indicated in the picture
below Ex.: 27 °f (or 15 °d) = 39 cycles.
To carry out the purifying cycle, follow these instructions:
Pict. 4
Note: Once the cycle has begun it cannot be stopped.
If a water conditioner is installed externally, follow the instructions given in the relative manual to regenerate the resins.
The flashing of the cycle lamp during the softening cycle, indicates a malfunction or a missed draining of the wash-tank (see
chap. ALARMS).
WARNING: In the case of water hardness above 35 °f it is advisable to install an external water softener
pag. 16

4.5 Drain pump system (optional)
To drain completely the wash-tank keep the machine ON, extract the overflow pipe and shut the door. Press the button 4for at
least a second (see chap. 3. CONTROLPANELAND RELATIVE SYMBOLS). The drain pump will automatically drain the wash-
tank.
When the drain is completed, turn the machine OFF.
Turn the machine OFF and, after 5 seconds, ON by pressing the button 2 to fill the wash-tank and run a new cycle (see chap. 3.
CONTROL PANELAND RELATIVE SYMBOLS).
Opening the door will stop the machine that will re-start when the door is shut.
During the wash-rinse cycle the water in excess is automatically drained.
Pict. 5
4.6 Compliance with hygiene regulations and H.A.C.C.P.
• When starting the machine ON, no wash-cycle will be starting until the set boiler and wash-tank temperatures are reached.
During operation, the machine will not start the rinse cycle till the set boiler temperature is reached.
• The machines are equipped with a temperature indicator F5 which lights up when the boiler and the tub have reached the
preset temperature (see chap. 3. CONTROL PANEL AND RELATIVE SYMBOLS - values set by the manufacturer). It is
recommended to wait for this light to go on before starting the next cycle.

8. ECOLOGICAL ASPECTS
8.1 Recommendations for optimum use of energy, water and additives
Dispensing of salt: A pre-set quantity (by the manufacturer) of salt is injected in the resins every
regeneration cycle. t is important to observe the number of regeneration cycles recommended in paragraph
4.4 Regeneration device (optional) in order to avoid salt spills or lime deposits.
If possible, use the machine at full load: This will avoid wasting detergent, rinse aid, water and energy.
Detergents and rinse aids: Use detergents and rinse aids having the highest biodegradability so that the environment is better
respected. Have the correct dosage according to the water hardness checked at least once a year. An excess of product
pollutes rivers and seas, whereas an insufficient amount compromises dish washing and/or hygiene.
Tank and boiler temperatures: The temperatures of the tank and boiler are set by the manufacturer so as to get the best
washing results with the majority of detergents on the market. These can be reset by the installer according to the detergent
used.
Cleaning off: Carefully clean off the kitchenware using water at ambient temperature with moderation so as to make removal
of animal fats easier. To remove encrusted matter, soaking in hot water is recommended.
Notes: Wash the objects as soon as possible in order to prevent the deposits from drying and jeopardizing the effectiveness of
the washing.
To get an efficient wash, it is advisable to regularly clean and maintain the dishwasher (see chap.5. MAINTENANCE).
Non-compliance with the above recommendations or with any and all information within the manual could result in
a waste of energy, water, and detergent, further causing an increase in user costs and/or a reduction in
performance.
