■ ■ ■■■■■■■■■■■■■■Please note: We recommend to set the time (chapter 26.7). If
you have not used 75 liters of water in three months, the filter
monitor will indicate that a filter change is necessary.
Important: Once the filter has lost its calcium suppressing
abilities, calcium will build up inside the machine. Since the
Water Hardness Selector is off, the machine will not remind you
when to decalcify. This could clog and ruin your machine.
•Push the Rinse Button. INSERT FILTERPRESS BUTTON.
•Remove the old filter and set the extension rod aside. The
used filter cartridge is environmentally friendly and can be
disposed with your regular household trash.
Important: Keep the Extension Rod
•Make sure the water tank is empty.
•Remove the new cartridge from its bag and rinse under
running water. Now install as explained in chapter 23A.
•Place a 20 oz. container under the Auto Cappuccino System.
•Push and hold the Rinse Button until the display shows
FILTER RINS.For the next 90 seconds the Z5 will push
water through the cartridge and out through the milk nozzle.
Initially, the water may have a slight discoloration. The program
will stop automatically. The display shows UNIT IS HEATING
and then COFFEE READY.
24. WATER HARDNESS MONITOR
If you do not use the Clearyl Filter Cartridge (chapters 23 – 23B.)
the Z5 will remind you when it is time to perform a decalcifying
cycle. The machine is set to medium hard water. If you have
harder water you need to set it to a higher level. If you have soft-
er water you can set it to a lower level. If you are not sure about
the hardness of your water, ask your local water company for the
"Water Hardness in Grains." The Z5 will show you the water
hardness in the German hardness scale (which is a bit different
from the American "Grain" scale (see chart below).
You can also use the enclosed water hardness indicator strip to
determine the water hardness:
•Insert the stick for one second into the water you want to
use. Shake off any access water and wait for one minute.
•If all five fields of the test stick turn reddish, set the hardness
level to 5 squares. If four fields turn reddish, set the hardness
level to 4 squares and so on.
Please note: If you use Spring Water or Bottled Water you can
set the hardness level to 1, "extremely soft water".
The Z5 will give you the following options:
Not Active* Not Active — — —
1. extremely soft water 1-4 1-5 None
2. soft water 5-9 6-11 1 to 2
3. medium water 10-14 13-18 2 to 3
4. hard water 15-19 19-24 3 to 4
5. very hard water 20-24 25-30 4 to 5
6. extremely hard water 25 + 32 + All 5
*Not Active: You can only use this setting for distilled water.
Level 5 and Level 6: If your tab water is very hard and falls into
these two categories, decalcifying will be frequent. In this case
bottled water is recommended.
