ELECTRICAL INSTALLATION

This appliance is intended to be connected to a 3 x 11 Amps electrical supply and must be earthed.

PLUMBING 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.

ECOLOGICAL ASPECTS

Recommendations for optimal use of energy, water and additives

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.
Excess product pollutes rivers and seas while an insufficient 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 themarket. 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.
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.
