I am having a new pool installed and purchased the Si-45 system. The pool contractor installed the system last week. The water temp here is not warm enough to generate salt yet so the cell was not installed, just a pipe in it's place. The panel powers on and interestingly, has a salinity reading of 3200 although no salt has been added to the new pool. Check the salinity with a test strip and it is next to nothing. I thought that maybe the cell had to be installed to get a correct reading to I put it on for about 15 minutes with no change in the salinity reading. I called tech support where I bought the system and the tech did not seem to have an answer for it but was quick to tell me that there was not a problem with the panel. He then said that the 3200 was an average salinity reading which did not make sense because not salt has been added to pool. When I reminded him of that, he simply told me that I did not understand. He said I should just add salt to the pool. Has anyone else had this experience with a new unit? And by the way, I do know which reading the "salinity" level is. The tech also insinuated that I did not. Do not know what else would be reading "3200."
