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.

• Switch the main power switch OFF.

At the end of the washing cycle, a hot rinse cycle will take place.

The button START E will ﬂash when the cycle is completed.

N.B.: At cycle-end, keeping the door closed, objects will not dry. Take out the rack or keep the door open to allow the

evaporation, helping the drying of the objects.

crockery loading

• Drain the water by removing the overﬂow pipe.

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).

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.
