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.

product.
The detergent shall be the NO FOAM type, suitable for industrial dishwashers and must
comply with the EN 60335-2-58/A11 norms.
The use of good quality liquid detergents is recommended.
Follow the manufacturer’s recommendations for chemical dosage, related to the local water
hardness. 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 "DETERGENT LEVEL" (only with optional
"Sensor for Chemicals Low Level").
Rinse aid use
The rinse-aid chemical, shall be suitable for professional glass and dishwashers and must
comply with the EN 60335-2-58/A11 norms.

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 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.
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 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.
(see chap. MAINTENANCE)
• Do not dry or polish the washed objects with cloths, brushes or rags that are not sterile.

TROUBLESHOOTING
Type of Problem Possible Causes Cure
The machine does not
load water. Rinse area nozzles or solenoid-
valve filter blocked and/or scaled
with limestone.
Clean the rinse arm nozzles, conductors and solenoid-valve
filter. Contact the Rhima Service Department.
Defective pressure-switch.
Washing results are
unsatisfactory.
The washing nozzles are obstructed
or the rack does not rotate.
Clean the nozzles carefully, and check the right positioning
of the wash-arm, tightening firmly.
Foam is present. Use no-foam detergents or reduce the dose in use. Check
the rinse-aid dosage.
Fats or starches not removed. Insufficient detergent concentration.
Filters are dirty. Remove filters, clean with brush under a jet of water and
replace in original position.
Check tank temperature (which
must be between 55°C and 60°C).

porous for material wear.
Replace type of objects used. If the dirt on the objects is
dry and old, soak before washing.
Streaks and spots on
objects.
Too much rinse-aid chemical.
Too hard water. Check the water quality. Water must not exceed 8°f in
hardness.
