| - Depending on the frequency of use and the general operating conditions, the salt solutions maintain their characteristics for 6 - 12 months, after which they must be replaced. Perform a visual check every 2 - 3 months. There must be a minimum of 10 % of undissolved salt at the bottom of the chamber (max. 90 %). The salt must be clean, otherwise it must be reprepared. | - Depending on the frequency of use and the general operating conditions, the salt solutions maintain their characteristics for 6 - 12 months, after which they must be replaced.
