cium content, the harder the water is.
The machine monitors the volume of water passing
through it in conjunction with the hardness of the
water. Descaling will have to be done more often for
hard water.
The local water authority will be able to tell you the
hardness of water in your area or you can measure
the hardness yourself using the enclosed test strip:
Dip the strip in your drinking water for one sec-

700 ppm), the water
