5.1 - WATER SOFTENER
Use appropriate salts or kitchen salt (SODIUM CHLORIDE) Na CL to reactivate the water softener when necessary. Hard water is caused by calcium
and magnesium. Hard water is not harmful or a health hazard but it can cause scaling in the pipes and water collection tanks.
Water is hard when it reaches 30-45° on the French hardness scale and is very hard at above 45°. To measure the hardness of your water, use the
testing kits sold in chemists or at one of our after-sales service centres.
Using a water softener will save on electricity and maintenance costs.
