Joe, you're still making chlorine so not much to do but install equipment, add salt, turn on. it takes a few days to get an accurate reading of salt level. add just a little too much and the level jumps way up. only way to lower salt level is take out enough water until level drops. I add less than required amount, run a few days and check again. one morning after adding salt it can be 2600ppm and that afternoon 4500ppm. 28-3200 is good on the systems I use. too low it stops producing, too much same thing. a recent install owner told me he did not have to add ANYTHING for 3 months, and then just some salt from backwashing loss. you will get more staining, but metal remover and asorbic acid will take those off in a day or two.repeat when needed, (6-10 weeks depending on metals in city water) no equipment changes other than adding the unit. takes me about an hour to install, but that's while I'm plumbing everything so I lay it out so I have room. the system I use needs 16" straight run for the flow meter, but the 12" unit can be used before the flow meter. you may have to re-plumb to get that length, but it's just PVC. the chlorine level is a trial and error thing. run a few days/week, check level and adjust output level. every 3 months check element light comes on. remove unit, check for scale, wash with 10-20% muriatic acid and water, reinstall. 15 minutes. one customer left his at 100% for a month or two. took 3 months with unit off for cholrine level to drop. yes, pool stores hate chlorine generators. chlorine prices have doubled since last year.. so it shouldn't take too long to recoup investment
