I installed a new to me Blue Works Model LPH40-B-T. I got an awesome deal on it from a friend of mine. It is supposed to be for a pool up to 40,000 gallons. My pool is a bout 24,000 gallons. I have had it installed for about 2 weeks now, and it is working great! I have not added a drop of liquid Chlorine since the install. I currently have the generator set on 16% and my chlorine level stays right at 4 PPM . I started out with the generator set on 50% but my chlorine levels were as high as 10 to 14 PPM so I started to turn the dial down until I got to where the chlorine level is now. The only thing that seems weird to me is whenever the cell is generating it shows a negative amperage. I know it runs reverse polarity to clean the cell, but I have never saw a positive amperage shown on the display. Is it possible that I wired something wrong? Should I even be concerned about this since everything else seems to be working great?
