11SYMPTOM: Cloudy water conditions even though the unit appears to be operating properly.SYMPTOM: Water is backing into the ozonator when the system is ON or OFF.SYMPTOM: The red LED light is not lit.When your system is in its ON cycle, a suction of air is being pulled through the tubingfrom the ozonator to the return line. When the system is in its OFF cycle, water tendsto flow back in the tubing toward the ozonator. Therefore, mounting your ozone unit ashigh as possible in relation to the spa water level is important. There is also a one-waycheck valve provided to prevent the back flow of water from reaching the ozonator. As asecondary precaution, a Hartford Loop in the tubing will help prevent water damage to theAquatic 2. Keep in mind, the Hartford Loop should also be hanging above water level.This means there is no power to the Aquatic 2. Check the electrical connections and thenthe fuse.TROUBLESHOOTINGPossible Cause Corrective ActionThe unit and pump did not operate longenoughIncrease the operating time (minimum 6 hours isrecommended)Total alkalinity is not correct Adjust total alkalinity between 80 and 150 ppmpH is not correctly balanced Check for proper pH between 7.2 and 7.6Not enough suctionClear any obstruction in the water lines or return fitting,straighten any kinks in the water or ozone plumbing,and clean the spa filter.The filter is dirty, loose or cracked Check/replace the spa filter as needed.There are metals or minerals in the waterOzone may react with metals or minerals in the water(this is common when new water is added) causingcloudy water. Check alkalinity, pH and clean filter. Runfiltration system and ozone 24 hours.
