2 Preparing and using your IMPRESSA for the first time
Lift the cartridge holder and insert the filter cartridge into
the water tank, applying slight pressure.
Close the cartridge holder. It will click into place audibly.
Fill the water tank with fresh, cold water and reinsert.
Place a receptacle (containing at least 500 ml) under the
cappuccino nozzle.
Turn the selection lever of the nozzle to the steam position n.
c T Press the maintenance button.
FILTER RINS., water will flow out of the nozzle.
You can interrupt filter rinsing at any time by pressing any
button.
The water may be slightly discoloured. This is not harmful to
health and does not affect the taste.
Filter rinsing stops automatically after approx. 500 ml.
COFFEE READY appears on the display. The filter is now
activated.
The harder the water is, the more frequently the IMPRESSA needs to
be descaled. It is therefore important to adjust the water hardness.
The water hardness can be adjusted on a continuous scale between
1° dH and 30° dH. This can also be deactivated, which means that
the IMPRESSA will not let you know when it has to be descaled.
However, if you are using the CLARIS plus filter cartridge and
have activated it, you will not be able to adjust the water hard-
ness.
You can find out what the water hardness is by using the Aquadur®
test strips supplied as standard.
Hold the test strip briefly (for one second) under flowing
water. Shake off the water.
