To avoid the build-up of calcium
deposits on glassware and the
machine, the water may need to be
softened (where the supply hardness
exceeds 107 ppm CaCO
3
).
To ensure a steady supply of soft water,
the water softener must always be:
1. correctly set (programmed) and
2. regenerated with salt as soon as the
"Recharge Softener" indicator
illuminates.
The water softener should be set to
correspond with the water hardness
upon installation of the machine.
Your local water authority can advise
you on the water hardness in your area.
Setting the water softener
The machine is set at the factory for a
water hardness setting of 19*,
corresponding to 339 ppm CaCO
3
. If
your water supply is harder or softer
than this, the setting of the controls
should be changed.
Where the water hardness fluctuates
e.g. between 160 - 310 ppm, always
program the machine to the higher
value, 310 ppm in this example.
