(1) Special model for high baskets

5
This machine is built with high quality materials in particular AISI 304 stainless steel (AISI 316 for boilers and tanks) with a
wall thickness to ensure a long lifetime.
Pre-wash module (the presence depends on the model chosen): a preliminary washing is carried out with low temp-
erature thermostatically controlled to melt the alimentary residuals and avoid the proteins denaturation.
Wash module: a proper washing of the baskets is performed with temperature thermostatically controlled.
Rinse module: 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 two cases:
1. The machine is working in vain (it is in operation but it is not used).
2. The machine is in operation but a basket accumulation exiting the machine causes the limit switch SQ1 to trip (F1).
In these cases, the timer set by default at 300 seconds trips.
By inserting a basket or clearing the exit the machine restarts automatically to operate.
Available options
Dryer E:
It conveys hot and dry air that creates the ideal conditions for rapid drying.
The dryer heating can be turned on or off by the operator.
Stage dryer E:
An air knife removes the water from the basket, by using a narrow focused stream of air.
Heat recovery G:
The goal is the recovery of the steam heat exiting the machine that otherwise would be dispersed, and use it to pre-heat
the water entering the boiler.
The machine must have a cold water supply for the rinse.
Heat recovery with heat pump G:
The goal is the recovery of the steam heat exiting the machine that otherwise would be dispersed, and use it to pre-heat
the water entering the boiler.
It exploits a heat pump to further increase the water temperature entering the boiler.
The machine must have a cold water supply for the rinse.
WARNING: If this optional is present the Autotimer must be set to a minimum value of 300 seconds.
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.
Upper loading system H
Pressure Increase Pump:
It allows a proper machine operation when the feeding water pressure of the machine is lower than 200 kPa.
Inverter:
It allows adjusting the speed of the conveyor in 5 steps and reaching the DIN speed.

Baskets loading
Before loading the baskets it is necessary to carry out a proper cleaning offof the food residuals.
Follow these tips:
• Baskets must not lie inside one another, or be covering each other.
• Place the baskets so that all the surfaces can be reached by the water; otherwise the baskets cannot be washed properly.
• Make sure that the baskets are placed in a stable position and that they do not turn upside down.
• Place the baskets upside down for washing.
Some food, like carrots, tomatoes, ketchup, may contain natural colorant substances that may alter the baskets and plastic
parts if they are in large quantity.
The eventual color alteration does not mean that the plastic is not thermo-resistant.
Items not suitable to be washed in a dishwasher:
• Wooden baskets 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.
• Plastic baskets not thermo-resistant.
It is suggested to purchase only baskets suitable for washing in dishwashers.
The washing and drying effectiveness is determined by the baskets conformation. A basket with smooth and linear surfaces,
without any ribs and hollows where washing water could stand, gives the best drying results.
If after the washing the baskets are not clean or they have washing residuals it is mandatory to repeat the procedure.
If the machine is equipped with an upper loading system, do not to push forcefully the baskets on the machine, as
they must be gently placed and accompanied.

DETERGENTS
Using detergent
The detergent must be of good quality, of NON-FOAMING type, specific for use in automatic washing equipment.
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 baskets characteristics.
The detergent has to be inserted only in the wash tank 1. For manual dosing remember that the wash tank contains about
85 litres of water.
Note: It is highly recommended NOT to use detergents with chlorine-based reagents as they may damage stainless steel
Using rinse aid
It is possible to use the rinse aid to get quicker drying.
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 pump.
Too much chemicals might leave residuals on the baskets.
OBSERVANCE OF THE RULES OF HYGIENE AND H.A.C.C.P.
In order to meet the correct H.A.C.C.P. procedures remember to prepare a sheet with tables where the shift operator enters
the date and time the washing starts, the time the washing ends, the tanks and boilers temperatures and any other note/

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 basket
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 offthe baskets 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 par. MAIN-
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.
