Jura Capresso IMPRESSA C9 - Manual (Page 20)

Please note: If you use Spring or Bottled Water with low calcium
levels you can set the hardness to 3ºdH, "extremely soft water".
12b. CHANGING THE WATER HARDNESS MONITOR
READY .
Example: Change the hardness setting from 10ºdH to 20ºdH
• Push the Rotary Dial (Fig. 3.8) until display shows
RINSE .

The machine automatically reminds you when it is time to
decalcify (chapter 17.1).
Please note: You can set the hardness monitor to
INACTIVE . In
this case you must use distilled water. In this setting the C9 OT
will not remind you to decalcify the machine.
13. CLEARYL WATER FILTER CARTRIDGE
The machine comes with one Clearyl Water Filter Cartridge. The
Clearyl cartridge
• Reduces the water hardness up to 75%.
• Removes (if present) up to 85% chlorine, up to 90% lead, up
to 95% copper and up to 67% aluminum.
• Cleans the water through an upward current principle (Fig. 10)
just before the brewing cycle starts, ensuring freshly filtered
water every time you make coffee.
• Lasts for 75 liters (~2,500 oz.) of water or up to two months.
• Eliminates decalcifying except when using very hard water
(25 grains or higher), see chapter 12. In this case we recom-
mended to decalcify the machine once or twice a year.
• To reorder cartridges, see chapter 20.
13a. INSTALLING & ACTIVATING THE CLEARYL CARTRIDGE

*INACTIVE: You can only use this setting for distilled water.
Level 5 and Level 6: If the tap water falls into these two cate-
gories, decalcifying will be frequent. In this case bottled water is
recommended. Most bottled water has a low calcium level.
Please note: If your water has a high calcium content (level 5 or 6)
and you use the Clearyl Filter Cartridge we recommend to decalcify
the machine once or twice a year (chapter 17.2).
