Recommendations
• Use only regeneration salts designed for water softening upon regulation EN973;
• for optimal system operation, the use of clean salt and impurities free is recommended (for
example salt pellets);
• the sanitizing process (both with liquid and electrochlorination) may introduce chlorine
compounds which may reduce the lifetime of the ion exchange resins. Refer to the technical
guides for resins in common use, providing necessary checks on the system.
