This machine is built with high quality materials in particular AISI 304 stainless steel (AISI 316 for boilers and tanks) and in
high thickness to ensure a longer lifetime.
The machine is built in different sections:
Pre-wash module C (the presence depends on the model chosen): a preliminary rough washing is carried out with low
temperature thermostatically controlled to melt the alimentary residuals and avoid the proteins denaturation.
On machines with pre-wash, the initial tanks filling occurs in several phases:
- Phase 1: wash tanks only filling
- Phase 2: filling interruption. Water heating using the heating elements until a proper pre-wash temperature is reached
(factory-set)
- Phase 3: resume and filling conclusion
- Phase 4: resume and heating conclusion.
Wash module(s) D: a proper washing of the crockery is performed with temperature thermostatically controlled.
Rinse module F: a pre-rinse is performed that removes most of the detergent, then a final rinse is performed with high
temperature thermostatically controlled.
Autotimer: the Autotimer function (activated by default) allows stopping the machine if it is in start-mode but not operating
at the moment.
It can happen in these cases:
1. The machine is working in vain (it is in operation but it is not used).
2. The machine is in operation but an objects accumulation exiting the machine causes the limit switch SQ1 to trip (F1).
3. The machine is in operation with the drawer Mopen.
In these cases, the timer set by default at 300 seconds trips. When the time is over the energetic saving mode turns on.
By inserting some objects, clearing the exit or closing the drawer the machine restarts automatically to operate.
Automatic drain:
Each tank is provided with dedicated motorized valve. The end work draining occurs when the machine is in stand-by by
pressing the dedicated key and without having to open the doors and getting in touch with the washing solution.
If there is the Pre-wash module or the Automatic shower with drawer strainer optional, it is possible to drain only the pre-
wash tanks and then to ensure the pre-wash tanks regeneration (where most of the residuals accumulate) and to keep an
ecient and low consumption washing.

Dishes and cutlery loading
Before loading the dishes it is necessary to carry out a proper cleaning off of the food residuals.
It is not necessary to rinse the dishes with water before the loading.
Follow these tips:
• Crockery and cutlery must not lie inside one another, covering each other.
• Place the dishes so that all the surfaces can be reached by the water; otherwise the dishes cannot be washed properly.
• Make sure that the dishes are placed in a stable position and that the empty containers (cups, glasses, bowls, etc.) do
not turn upside down.
• Place all the empty containers like cups, glasses, etc., upside down.
• Place in tilted position the dishes with deep hollows, so that the water can drain.
• Make sure that the smaller dishes do not fall from the belt.
• Check that the dishes are not too tall or protruding.
• Do not wash trays horizontally.
Some food, like carrots, tomatoes, ketchup, may contain natural colorant substances that may alter the dishes and plastic
parts if they are in large quantity.
The eventual color alteration does not mean that the plastic is not thermo-resistant.
Dishes to not wash in a dishwasher
Dishes not suitable to be washed in a dishwasher:
• Wooden crockery and cutlery or with wooden parts; wood wraps and loses its characteristics if it is exposed to high
temperatures. In addition the glues used are not suitable for dishwashers; a consequence may be the handles detachment.
• Hand-made objects, valued vases or decorated glasses.
• Plastic dishes not thermo-resistant.
• Copper, brass, pewter or aluminum objects can discolor or become opaque.
• The decorations on glass can lose sparkle after a certain number of washes.
• Fragile glass or crystal objects can become opaque if washed many times.
It is suggested to purchase only crockery and cutlery suitable for washing in dishwashers.
Glasses can become opaque after many washes.
If after the washing the dishes are not clean or they have washing residuals (glasses, cups, bowls, etc., with liquid
on the inside) it is mandatory to repeat the procedure.
WARNING: Do not wash items contaminated by petrol, paint, pieces of steel or iron, ash, sand, wax,
lubricating grease. These substances damage the machine. Do not wash fragile items or made of
material that do not stand the washing process.

ECOLOGICAL ASPECTS
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
MAINTENANCE).
Non-compliance with the above points and all the information described in this manual could determine a waste of
energy, water and detergent, with consequent increase in operating costs and/or decrease in performance.
