8.2 Recommendations
• Use only regeneration salts designed for water softening in accordance with EN973;
• for optimal system operation, the use of clean salt, free from impurities, is recommended (for
example salt pellets);
• do not use ice melt, block, or rock salts;
• the sanitizing process (both with liquid and electrochlorination) may introduce chlorine

guides for resins in common use, providing necessary checks on the system.
