ELECTRICAL INSTALLATION
The Australian installation shall be in accordance with The Plumbing Code of Australia (PCA).
This appliance should be connected to a hot water supply (Max 65°C ) for in accordance
with Australian Standard AS/NZS 3500.1. for optimum performance.
The water supply pressure should be a minimum 200 kPa at all times and flow rate should
be at least 10 litres per minute. A static pressure higher than 600 kPa (73.5 psi) requires a
pressure reducing valve upstream of the supply line. If water pressure is below 150 kPa,
the use of a rinse booster pump is recommended.
This appliance is designed to drain to a tundish. Waste connection to a spigot is not
recommended and may cause draining issues.
The drainpipe should withstand 70°C (158°F) in continuous duty conditions.
The grey water drain hose must have a fixed watertight seal above the tundish in
accordance with the Australian Standard AS/NZS 3500.2.

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 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).

hardness.
By request the dishwasher can be equipped with an electric detergent dispenser (always recommended).
1cm. of the product drawn into the tube is equal to about 0.15 g. A correct amount of detergent is very important for a
successful wash.
Should the detergent lack, the display will show NO DE (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.

N.B.: The machine must not be switched ON during the emptying phase.
IMPORTANT: Always turn the main wall switch offand close the water tap at the end of use.
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 filters, nozzles and piping.
• Drain the wash tank and clean the filters 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 finger marks.
• Do not dry or polish the washed objects with cloths, brushes or rags that are not sterile.

ECOLOGICAL ASPECTS
Recommendations for optimal use of energy, water and additives
Chemical dosing: A pre-set (by the manufacturer) quantity of Chemical is injected in the resins at each cycle.
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 once a year. Excess product pollutes rivers and seas while an
insufficient dose results in unsatisfactory objects 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 effective washing.
For effective washing routine dishwasher cleaning and maintenance is advised (see chap. MAINTENANCE).
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.
