Machine Positioning
Unpack machine, check for damage and complete delivery.
Install machine on sound waterproof self-draining floor and use adjustable feet to level
machine.
NOTE: Failure to level the machine correctly may result in leaking during the cycle,
overflowing from the door sill, poor hygiene through the wash tank not being able to
drain correctly, and/or visibly uneven door.
Allow room for detergent to one side of machine or in adjacent cupboard. 20 litre container
requires approximately W 250mm x D 350mm x H 450 mm, but smaller containers are
available from many suppliers.
Inlet Water
Incoming water should be within the following standard requirements:
Temperature: 6C.
NOTE: Low temperatures will increase the recovery time between cycles and depending
on the chemical being used, may result in excessive foaming if the machine is started
before the wash water is up to a suitable temperature.
NOTE: Excessively high temperatures may damage the solenoid which can result in
flooding should this component fail. High temperature solenoids are available and can be
retrofitted if necessary.
Connection: 20 mm (3/4BSP) male flexible hose supplied.
NOTE: Flush supply line before connection. Poor quality supply or excessive water
hardness may affect performance or damage machine filtration and/or softening is
recommended.
Flow rate: minimum 20 litres per minute.
Pressure: between 200 and 350 kPa.
NOTE: If above 350kPa fit pressure limiter valve (LPV). Do not use small diameter plastic
supply lines.
Consumption: Approximately 2.6 litres per cycle.
Backflow prevention: Atmospheric Vacuum Breaker (AVB) fitted standard.
Water Quality Requirements
The incoming water should also be within the following parameters:
Hardness ppm pH
min 20 7
max 100 8
Ions Cl- SO
4
Fe Mn Cu Cl
2
Max mg/L 100 400 0.1 0.5 0.05 0.1
NOTE: Levels above or below the stated requirements can be expected to increase
component wear and reduce the expected useful life of the dishwasher. If in doubt, it is
best to consult a water specialist and have the incoming water professionally tested and
treated if necessary.
Power
Electrical supply required is 15A 240V 50Hz via switched outlet adjacent to machine.
Easily upgradeable to three phase 15A 415V 50Hz.
NOTE: Equipment contains dangerous voltages and can be hazardous if installed or
operated incorrectly. Non –compliance with warnings or failure to follow the
instructions contained in this manual can result in loss of life, severe personal injury or
serious damage to property.
