My friend has one of these and it is not producing any chlorine. His chlorine tests show no chlorine in the water. He is treating his water with tablets. We suspect it is hooked up wrong, a year ago. The people who installed it had never installed one. The people who sold it to him ( the installer) did not know how to operate it. We are in Madison, MS and noone knows anything about this product. The company refuses to help resolve situation. Question is, does anyone know about this unit and how we can troubleshoot it. I am going back in the morning and take pictures of the plumbing. Any advice.
