Depending on the water volume used, regularly verify
the salt consumption. If necessary, refill some regene-
ration salt (use only quality complying with EN 973).
Observe the necessary hygiene requirements when
refilling salt. For instance, the salt packages should be
cleaned prior to use to prevent impurities from getting
into the salt tank. The regenerating salt should be pou-
red in the salt tank as soon as the package is opened.
Make sure not to overfill the salt tank and close it
properly when the work is completed. Avoid the use of
already opened packages. Store the salt exclusively in
clean and dry rooms.

The external surface of the water softening system
can be cleaned with a usual household cleaner (soft
soap). Solvents, detergents with alcohol and lacquers
affect the durability of synthetic parts (danger of
breaking) and shall not be used.
Should the water supply to the water softener be
interrupted (main isolation closed or on "bypass"),
unplug the water softening system.
