Adjusting Filter Monitor
(Optional):
The filter-life monitor is factory-set to 9001 litres
(default) which is suitable for most parts of the
UK with average or medium water hardness.
Hard and Soft Water: The effectiveness of
the filter will be reduced in hard water areas
(and should be replaced more frequently), or
extended in soft water areas where scale is less
of a problem.
If in doubt as to the hardness of water
supplied in your area, consult your local
water authority or Instanta Technical
Support.
The filter-life monitor can be changed from the
default setting, to suit the local water conditions
in your area. As an example; locations with soft
water might set the monitor between 11,000 to
14,000 litres, whereas locations with particularly
hard water may choose to set between 5,000 to
7,000 litres.
