1.9 Electrical connection - Characteristics
Electrical connection must be carried out in compliance with the legislation in force and the relevant technical standards.
Make sure that the supply voltage is the same as reported on the machine plate and that the network can stand the needed
power absorption shown on the same 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.
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.
1.10 Water supply connection - Characteristics
Water connections must be carried out in compliance with the legislation in force and the relevant technical standards.
The water system must have characteristics between the parameters specified in Tab. 1

Connect the machine's water supply with an interrupt valve capable of quickly and completely shutting off water
intake.
*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 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.
Note: Any damage caused by limestone (calcareous water higher-up than 8 °f and without water-softener) will not be covered
by warranty.
A periodical check of the supplied water hardness is highly recommended.
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.
The machine must be supplied with cold water (max 15 °C), if equipped with the Heat Recovery System. A hot water supply on
that connection will not allow any energy recovery or steam reduction.
WARNING: Heat Recovery system and Steam Condenser - installation (optional)
It is strictly forbidden to connect the machine’s vent directly with the outdoor!
Cold weather conditions might seriously damage the Thermal Recovery system or the Steam
Condenser (outside temperatures).
****The water supply temperature shall never exceed 55 °C.

4.2 Objects loading
Before objects loading in the machine, coarsely clean them from the leftover food.
It isn't necessary to rinse the objects 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.
Note the following recommendations:
• Objects should not be inserted inside one another, covering each other.
• Place the objects in order to all surfaces can be reached by water; otherwise the objects are not
washed.
• Make sure all the objects are in a stable position and that the hollow containers don't overturn
(baskets, pots, pans, bowls, etc.) .
• Place in the rack all the hollow containers such as baskets, pots, pans, bowls, etc. upside-down.
• Place the objects with deep hollow with upper face downwards, so that water can flow out.
• Make sure the smaller objects do not fall from the rack.
• Check all the wash arms runs freely and they are not blocked by too tall or too prominent objects.
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 objects and plastic parts colors.
Any discoloration does not mean that the plastic is not heat resistant.

adjusted).
Not suitable for dishwasher:
• Wooden objects 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 or precious vases
• Not heat-resistant plastic objects.
• 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.
We recommend to buy exclusively objects suitable for dishwashing.
It is mandatory to repeat the washing cycle if at the end of the cycle the objects are not well clean or if there are
washing residues (baskets, pots, pans, bowls, etc. with liquid inside).
4.3 Use of detergent
The detergent must be of good quality, of NON-FOAMING type, specific for the mechanical washing of dishes.
By request the dishwasher can be equipped with an electric detergent dispenser (always recommended).

5.2 Special Maintenance
Once or twice a year have a qualified technician inspect the machine:
1 Clean the electrovalve filter.
2 To remove residual deposits.
3 To check the watertight of the seals for water loading and unloading connections.
4 Check the perfect state and/or wear of the components. If a component is damaged or oxidized replace it immediately with
genuine spare parts only
5 Check the efficiency of the dispensers
6 Check the efficiency of the door safety switch.
7 Tighten firmly all electrical connections.
Pay attention to do not wet the motor or any electric part.
Perform maintenance with the wall-mounted main switch turned OFF.
Every 3-4 years of machine use, double-check the tightening and the efficiency of all electrical contacts, with special
attention to the contacts of starters and relays.
Increase controls frequency if the machine is operating in heavy or intensive conditions.
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.
• Scrape food from the dishes carefully in order not to clog the filters, nozzles and pipes.
• Unload the wash tub and clean the filters at least twice a day.
• Check that the amount of detergent and rinse aid dispensed is correct (as suggested by the supplier of the product). In the
morning, before starting the machine, check that the quantity of chemicals in the canisters is enough for daily supply.
• Always clean the support floor of the dishes.
• Extract the rack with clean hands or gloves to avoid finger marks.
• Do not dry or polish the dishes with non-sterilized cloths, brushes, or dusters.
7. ECOLOGICAL ASPECTS
7.1 Recommendations for optimum use of energy, water and additives
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.
