Capresso IMPRESSA C5 - Manual (Page 17)

(hand tight) and the frother is completely pushed up against the
steam nozzle (Fig. 15).
CAUTION: If the tip of the frother is blocked by hardened milk
deposits it is possible that the frother can be pushed off during
steaming. This can cause burns and injuries.
14. WATER CARE
The C5 works with tap water, bottled water, distilled water. We
recommend using tap water or bottled water. Distilled water has
no minerals and does not improve the taste of coffee. Water that
is heated inside the machine leads to calcium deposits.
Tap water has a varying degree of water hardness (chapter 14a).
Most bottled water has a low level of water hardness.
IMPORTANT: do not use carbonated water or any other liquid in
the water tank.
You have the following options to take care of the water.
• Decalcifying System (chapter 18). The machine is factory
pre-set to automatically remind you to decalcify.
• Clearyl Blue Water Filter Cartridge (chapter 15a).
14a. WATER HARDNESS MONITOR
The C5 is set to a medium hard water level (level 2 below). The
C5 can be set to five different water hardness settings (see
below). If you are not sure about the hardness of your water ask
your local water company for the "Water Hardness in Grains."
You can also use the water hardness indicator strip ("Aquadur"
Fig. 1,16) to determine the water hardness:
• Insert the strip for one second into the water you want to use.
• Shake off any access water and wait for one minute.
One or more sections of the indicator strip will turn reddish.
The more sections turn reddish the harder your water is. If all
four sections turn reddish your tap water is very hard (level 4
below). You might want to consider using bottled water.
• Change the water hardness setting according to the table
below.
Level Water hardness Cup symbols highlighted
Level in grains in programming...
0 Hardness monitor is off no cup symbol on
1 2 to 9 grains one cup symbol on
2 10 to 19 grains two cup symbols on
3 20 to 29 grains three cup symbols on
4 30 + grains four cup symbols on
Please note: If you use Spring or Bottled Water with low calcium
levels you can set the hardness to level 1 above.
14b. CHANGING THE WATER HARDNESS MONITOR
Example: Change the hardness setting from level 2 to level 1.
Your machine is turned off, but in stand-by mode. Only the
On symbol is visible.
• Open the Access Door (Fig 1,2a).
• Push and hold the DECALCIFYING button until its light is on.
Two of the cup symbols above the DIAL will be highlighted.
• Turn the DIAL until only one symbol is highlighted.
• Push the DIAL to confirm the new setting.
The machine will return to stand-by mode.
Please note: You can turn off the hardness monitor (level 0). In
this case you must use distilled water. The machine will not
remind you to decalcify the inner parts.
