particles into the spray arm jets, and
rinse well under running water.
Remove the spray arms as follows:
Take any mobile units out of the wash
cabinet.
Spray arms in the wash cabinet:

Use an SW 60 spanner to loosen the
connection and then pull the spray
arm upwards or downwards.Spray arms in mobile units/modules:
Turn the nut (left hand thread)
together with the spray arm
clockwise and then pull the spray
arm downwards and off.
After cleaning the spray arms screw
them back into position.
After replacing the spray arms rotate
them to make sure they move freely.

							All electrical work must be carried
out by a suitably qualified and
competent person in accordance
with local and national safety
regulations (BS 7671 in the UK).
–Connection should be made via a
suitable isolator with an on-off switch
which is easily accessible for
servicing after the machine has been
installed.
–An electrical safety test must be
carried out after installation and after
any servicing work. It is therefore
essential that the on-off switch is
easily accessible.
– When switched off there must be an
all-pole contact gap of at least 3 mm
in the isolator switch.
– For extra safety it is advisable to
protect the machine with a suitable
residual current device (RCD).
–
Check that the phase rotation is
correct when connecting the
machine. Failure to do so could have
an adverse effect on the circulation
pump and impair the wash quality.
–
Equipotential bonding should be
carried out.
–
For technical data see data plate or
wiring diagram supplied.The machine must only be operated
with the voltage, frequency and fusing
shown on thedata plate.
Further notes on electrical

connected to the mains water
supply and to the drainage system
in accordance with local and
national water regulations. Please
refer to the installation diagram
supplied with the machine.
–If the water supply has a high iron
content there is a danger of
corrosion occurring on items being
processed in the machine, as well as
in the machine itself.
If the chloride content of the water
exceeds 100 mg/l the risk of
corrosion to items being processed
in the machine will be further
increased.
