Operation

5.1. Recommendations
• Use only regenerate salts designed for water softening 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) introduces chlorine elements which may reduce the life of
the ion exchange resins. Refer to the technical guides for resins in common use, providing necessary checks on the system.
