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.

ATTENTION: 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:

  • 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 fl ow 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).
Detergent use
By request the dishwasher can be equipped with an electric detergent dispenser (always recommended). The machine automatically sucks the detergent.
The detergent shall be the NO FOAM type, suitable for industrial dishwashers. The use of good quality liquid detergents is recommended.
Follow the manufacturer’s recommendations for chemical dosage, related to the local water hardness.
A correct amount of detergent is very important for a successful wash.
Should the detergent lack the F10 indicator on the display fl ashes (only with optional “Sensor for Chemicals Low Level”).

Rinse aid use
The machine has a standard rinse aid dispenser. The machine automatically sucks the product.
The rinse-aid chemical, shall be suitable for professional glass and dishwashers. It is advisable to rely on specialized retailers in the sector.
Should the rinse-aid chemical lack the F19 indicator on the display fl ashes (only with optional “Sensor for Chemicals Low Level”).

Drain pump system (option)
The cycle drain pump works in an automatic and independent way.
At the end of the day, to completely empty the tank:
Remove the overfl ow.
Press the KEY D; the tank draining indicator F3 and the totalizer turn on for the time set by the program.
After the draining is complete, the machine turns automatically in STAND-BY mode.

This operation is also possible with machine in stand by-mode. Once fi nished, the machine returns to the initial mode.
See chap. 8 if an alarm appears.
Note: The machine must not be switched ON during the emptying phase.
IMPORTANT: Always turn the main wall switch off and close the water valve at the end of use.

Regeneration function (option)
Should the machine be equipped with a water-softener circuit, this will be fully automatic.
When needed, a 120” regeneration cycle will automatically activate (machine ON). During this phase the indicator F6 switches on (steady).

If needed the cycle can be activated even during the wash-tank loading. If the activation is made during the wash-cycle, this will be longer.
The circuit board is designed to call periodically for a 20 min. manual regeneration cycle (according with the water hardness adjusted). This regeneration cycle can also be activated by the user, should the rinse quality be dissatisfactory. The indicator F6 fl ashes.

IMPORTANT: Before starting a regeneration cycle check if there is salt in the special container.
When the indicator F8 fl ashes on the display it means that the salt level in the bowl is low (only on machines equipped with the optional Water Softener).

To add salt, open the machine door and unscrew the salt container plug inside the tank.
Fill the special container with specifi c coarse salt for regeneration (coarse salt: 0,500kg – 1-4 mm grains), being careful not to spill it into the tank. A strong concentration of salt can negatively aff ect the correct functioning and service life of the machine and generate rust and the steel corrosion. After fi lling with salt, lock the plug tightly.
To start a complete regeneration cycle it is needed to switch off the machine with the key E.
The indicator F4 turns on.
Drain the tank. Remove the overfl ow. For machines equipped with drain pump see par. 3.5.
Press the key B. The indicator F6 turns on. The machine carries out with the various phases.
The cycle is fi nished when the indicator F6 goes off after around 20 minutes.

The machine returns to stand by-mode (indicator F4 lighted).
Note: Regeneration times will be blocked only if the door is opened.
The optional regeneration is not allowed in the following conditions:

  • During programming.
  • During the wash cycle.
  • During manual draining.
  • If the tank is fi lled; in this case the message drAIn tAnk will be displayed for about 4sec.
  • If the machine is ON.

In the case of water hardness above 35°f it is advisable to install an external water softener

Door opening piston function (option)
The machine can be equipped with an automatic hood lifting device.
The piston operation always performs as follows

  • The hood lifts for about 3 cm to allow the fi rst dripping and steam exhausting from the wash tank.
  • Stand-by for 3 sec.
  • The hood is fully lifted.

Inlet water temperature probe (option)
The machine can be equipped with a built-in inlet water probe that allows verifying the boiler inlet water-temperature.
With machine in ready-mode, by pressing both the key A and C it is possible to visualize the temperature.

ECOLOGICAL ASPECTS

Recommendations for optimal use of energy, water and additives
Salt dosing: A pre-set (by the manufacturer) quantity of salt is injected in the resins at each regeneration cycle. It is important to observe the number of regeneration cycles recommended in paragraph 3.6 Regeneration device in order to avoid salt spills or lime deposits.
Use the machine fully loaded when possible: This shall prevent detergent, rinse aid, water and energy consumption waste.
Detergent and rinse-aids: Use detergents and rinse-aid chemicals with high biodegradability, to best respect the environment.
Verify proper dosage in relation to water hardness at least three times a year. Excess product pollutes rivers and seas while  an insuffi cient dose results in unsatisfactory dish washing and/or hygiene.
Boiler and Wash-Tank temperatures: The boiler and tank temperatures are set by the manufacturer in order to obtain the best washing results with detergents on the market. The temperatures can be reset by the installer in relation to your detergent.

Pre-washing: Carefully pre-wash with a moderate amount of water at room temperature to facilitate the removal of animal fats. To remove encrusted materials warm water soaking is recommended.
Note: Wash objects as soon as possible to avoid deposits from drying and compromise eff ective washing.
For eff ective washing routine dishwasher cleaning and maintenance is advised (see chap. 6).
Disregarding the points listed above and of any the information contained in this manual can cause energy, water and detergent waste with a subsequent increase in running costs and/or performance reduction.

H.A.C.C.P. AND HYGIENE REGULATIONS

  • 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.

  • Remove carefully all solids from the objects to be washed, to avoid obstruction of fi lters, nozzles and piping.

  • Drain the wash tank and clean the fi lters at least twice a day.

  • Check if the detergent and rinse-aid dosage are correct (as recommended by the manufacturer). In the morning, before starting the machine, check that the quantity of chemicals in the canisters is enough for daily supply.

  • Keep your working tables clean.

  • Extract the rack with clean hands or gloves to avoid fi nger marks.
