SCClub operating instructions
Commissioning
Inserting the water lter 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 lter should be installed, as
otherwise the co󰀨ee machine can be damaged due
to calcication.
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 lter 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.
