S4: hard water (46-60 °F or 26-33 °H) - salt recommended
S5: very hard water (61-90 °F or 34-50 °H) - salt recommended

How to set the S level

The regulator is located under the cover of the salt compartment and can be turned using a coin. The recommended default position is 4, but you should adjust it according to the actual hardness of your local water. Contact your water supplier to find out the hardness level in your area.
