Determining The Water Hardness; Service Life - Schaerer Coffee Club Guía Breve

Commissioning | Commissioning programme
Inserting the water filter for the water tank
(optional)
This point is a step taken during the commissioning
programme.
For drinking water with a carbonate hardness above
5°dKH, a Schaerer water filter should be installed,
as otherwise the coffee machine can be damaged
due to calcification.

Determining the water hardness

* Obtain the water hardness of the drinking water
from the water supplier or use the carbonate
hardness tester (with instructions) in the
accessories.
The carbonate hardness test is included in the
accessories.

Service life

The supplied water filter for the water tank
(200 l) at 10 °dkH has a service life for
200 litres of water. The actual service life is
dependent on the drinking water hardness and can
be found in the following table.
