If already softened hot or cold mains water is available with a hardness value of less than 15°F (expressed in French degrees) or 8°D (expressed in German degrees), the regeneration cycle of the built-in softener must be inhibited and salt must not be added to the softener.
Če je že na voljo mehka vroča ali mrzla voda iz vodovoda s trdoto manj kot 15°F (izraženo v francoskih stopinjah) ali 8°D (izraženo v nemških stopinjah), je treba regeneracijski cikel vgrajene naprave za mehčanje vode onemogočiti, mehčalcu pa se ne sme dodati soli.
