Tip: If your tap water falls into the categories "very hard or
extremely hard" we recommend using bottled water. Please
note: If you use the Clearyl Filter with such hard water we 
recommend  decalcifying the machine once or twice a year
(chapter 18.3).

Please note: If you use Spring Water or Bottled Water you can
set the hardness level to 3ºdH, "extremely soft water".

• Push and hold the P button (Fig. 4) until the display shows

.

• Turn the Rotary Dial until desired hardness level is displayed.

. 

• Push the P button. 

The machine will automatically remind you when it is time to
decalcify (chapter 18.3).
Please note: You can set the hardness monitor to 

. 

In this case you must use distilled water.

17. CLEARYL WATER FILTER CARTRIDGE
To avoid decalcifying and to always have fresh water we recom-
mend using the Clearyl Water Filter. The ENA comes with one
Clearyl Water Filter Cartridge.
To reorder cartridges, see chapter 31.
The Clearyl cartridge
• transforms your tap water into pH-neutral water and reduces

water hardness up to 75%,

• cleans the water through an upward current principle (Fig. 8)

just before the brewing cycle starts, ensuring freshly filtered
water every time you make coffee,

• removes (if present) up to 85% chlorine, up to 90% lead, up to

95% copper and up to 67% aluminum,

• contains only pure organic materials (ion exchangers and

active carbon) with no chemical additives,

• preserves fluorides and minerals,
• eliminates decalcifying except when using very hard

water (20 grains or higher), see chapter 16. In this case we
recommend to decalcify the machine once a year.

: Never install the cartridge before or during

"Preparing Machine For The First Time" (chapter 6).
