7.0.4 Replacing the filter
D Note:
Switch off the pure water dispenser before you
replace the filter.
The filter has a capacity of up to 3000 litres.
When 00 litres have passed through the
filter, the filter indicator c starts flashing to indicate
that you need to replace the filter. At this point,
the appliance can still dispense another 300 litres
of water, giving you time to arrange a new filter.
The filter indicator keeps flashing until 3000 litres
have passed through the filter. Then the filter
indicator lights up red continuously and the pure
water dispenser does not dispense water until you
replace the filter.
D Note:
We advise you to change the filter every
6 months, even though you might not have
consumed 3000 litres. Filter life is subject to the
actual level of impurities in your water supply.
The filter may therefore expire before 3000
litres without any warning period.
