Pentair PENTAIR 520554 PENTAIR 520554 (Open Box)

t is installed exactly as instructions say. I was just a replacement for the same model, so hook it up and plug it in. All lights are working, however, it is not producing chlorine. Had all levels tested according to instructions, installed it,shocked the pool with dry chlorine, set it on 100% for three days, tested three days later, zero chlorine in the pool. Test (at the pool store) said it needed a gallon of chlorine (they said power was the same), however, put a gallon of liquid chlorine in the 11,000 gallon pool. Tested 3 day later, zero chlorine. It has all the right ph, salt, etc. levels correct (I had all these tested before installation, before the powered chlorine, after and prior to and after the liquid chlorine application. The unit's lights are all correct however it is still not producing chlorine. Next I am going to super shock the pool with five gallons of chlorine and leave the unit at 80 or 100% and test three days later, if it is zero chlorine, the unit is not working and will have to be returned for a replacement. Perhaps the store that sold this through Amazon could call or email me with trouble shooting. 850-233-3229 SailorBoyRecords@aol.com Mr. E. F. Mitchell
