CAUTION
When you use the machine for the first time, you must set the water
hardness. If you do not know the hardness of your water, you can
find this out first. Use the Aquadur® test strips supplied with the
machine.
T Hold the test strip briefly (for 1 second) under flowing water.
Shake off the water.
T Wait for about 1 minute.
T You will then be able to read the degree of water hardness
from the discolouration of the Aquadur® test strip and the
description on the packaging.
If the machine is operated with a defective mains cable, there is a
danger of potentially fatal electric shock.
T Never use a machine which is damaged or has a defective
mains cable.
