Due to the unique filter formulation and technology,
conventional hardness test strips or digital meters cannot
accurately show if the ION media (boiler scale protection
and hardness reduction media) within the filter has been
exhausted.
The only way of judging if the ION media is exhausted and
therefore your filter needs to be replaced is by following the
subsequent steps:
1.
Press and hold the MENU and DOWN SCROLL button
simultaneously.
2.
You should see a similar information screen to this
example (Fig. 7.1).
3.
Take note of the "WATER USAGE" value then press the
POWER button to return from this menu.
4.
Take your GB Clark hardness value and add 2°
(otherwise use the PPM hardness value and add 30PPM).
Now compare this NEW HIGHER Clark hardness value against
the table in conjunction with the WATER USAGE value.
If the WATER USAGE figure is higher than the value
*REPLACE LITRES value in the table then filter will require
replacing.
Worked Example: WATER USAGE = 0862 litres, your local
water hardness is 11 °Clark, add 2 °Clark, then the 'REPLACE
LITRES' value in the table for 13 °Clark is 850 litres. In this
example the 'WATER USAGE' is more than 'REPLACE LITRES'
so the filter requires replacement.
Replacement filters can be obtained by contacting the service
agent number on the sticker on the top of the boiler.
If the filter does not need replacing (for instance you have
installed the product in a soft water supply area), you can
reset the filter reminder beep & indicator bar by pressing and
holding both the up () and down () buttons together.
IMPORTANT: Before you reset the filter counter you must
keep a written note of the WATER USAGE value for when you
next check your filter. When you come to recheck the WATER
USAGE you must add the 'new' and 'previous' WATER usage
totals together and use the combined total against the chart.
Whilst you get used to your likely personal filter replacement
schedule, we recommend re-checking filter life frequently to
protect the boiler from scale.
Due to our policy of continual improvement, we reserve the right to change specifications without prior notice.
