Hello again. I had an inspection done on my boiler. I mentioned to the tech. that I have 0-1 gpg hardness and he stated that I should attempt to get 3 gpg because at 0 gpg hardness the water can be corrosive/acidic for the heat exchanges in the boiler and in the indirect hw tank. After crunching the numbers again:
28 gpg hardness + (2.0 ppm iron x 4) = 36 compensated hardness - 3gpg that I now want to keep = 33 compensated hardness
33 x 210 gallons per day x 8 days = 55,440 grains needed to be removed (62,370 gains if adding an extra day for reserve.)
Looking at charts, I am in the 8-9 lbs/ft for salt dose. Again, it is a 2.5 cu ft softener. fleck 7000sxt
Questions I have:
-Does this look correct?
-Will Iron start to appear in the water along with the hardness I am trying to keep in the water?
-My manual mentions a "Safety Factor" setting. Is this not the same thing as adding the extra days worth of reserve to the total grains? Is adding a reserve amount into the equation redundant when using the "Safety Factor"?
-Is my "Unit Capacity" setting supposed to be at 80x1000 since I have an 80,000 grain system, or is this setting referring to something else?
-What should I set my "feedwater hardness" setting to. I would assume that it should now be set to 33, since this is my compensated gpg hardness?
-From re-reading the above posts, it appears that I set the desired salt dose by changing the times of the "regeneration cycle step times". If this is the case, what does the "feedwater hardness" setting do?
thanks in advance,
Dustin
