Finally had it installed yesterday! The salt level is reading 4600ppm so I took a sample up the pool store. Their reading was 3900, I bought a drop test kit and did that when I got home. My reading is 4600 exactly what the Dig-220 reads. Should I be concerned with that high level or just sit back and let it drop with backwashing and splash outs?
The installer put 9 bags of salt in my pool (which I think is around 20k gal). I dont even think he checked the salt level in the pool before dumping it in because he was going to give me some test strips but said he was out of them. Would my pool have salt already in it from another source?
Also, I had a new Pentair PNS Plus 48sqft DE filter installed yesterday, finally getting rid of the cartridge filter that wasnt doing a good job (old cartridges). My pressure rose 14psi overnight cleaning up the pool, so I decided to backwash it. My Autopilot directions say you push the "pump" button to turn it off, which I did, but it just displays "high pump" not "off for maintance". I have a 2 speed pump and I changed modes from "external timer" to "2 speed pump", is that the correct setting? Why doesn't it switch off for maintance? Maybe I'm not doing it right?
