8.6 Check the water hardness
The hardness of the drinking water and the set
hardness of the outlet water must be checked during
start-up and once a month thereafter, and corrected
if necessary.
Information about the outlet water hardness
The Trinkwasserverordnung (German drinking
water ordinance) stipulates a sodium limit of
200 mg/l. The limit has been set this low so that
people on a low sodium diet can still consume
drinking water and use it for cooking.
Reducing the hardness of drinking water by
1°dH increases the sodium content by 8.2 mg/l.
(Drinkingwaterhardness–Outletwaterhardness)
x 8.2 mg/l = increase in sodium content.
Test the water hardness
Fully open the tap at the nearest cold water tap point
upstream and downstream of the water softener and
run the water for 1 minute. Use AQUATEST to test
the hardness of the water and make a note of it.
