3Congratulations on your purchase of a RainSoft water treatmentsystem.This Owner’s Manual is designed to assist with the operation, mainte-nance, and installation of your water treatment system. It is our sincerehope that this manual is clear, concise, and helpful to you as a newowner.Questions? If you have any questions regarding the installation, oper-ation, or servicing of this system, please contact your local RainSoftDealer. Your local RainSoft Dealer is familiar with your particularwater conditions, and is able to address your concerns promptly andefficiently.Information on Water TreatmentSystemsThere are many misconceptions that have been developed about watertreatment systems. The most common topic of confusion is theamount of sodium (Na), not table salt (NaCl), that is added to thewater from a water conditioner. In reality, ion exchange does replacethe hardness ions in your water with sodium ions, but the commonmisconception is the amount used.For every 1 grain of hardness, the exchange process will deliverapproximately 8 milligrams of sodium per 1 liter of water. The amountof sodium present in a standard 8 ounce glass of treated water, that was10 grains hard prior to treatment, would be around 19 milligrams ofsodium. This is an insignificant amount of sodium considering atypical slice of white bread has about 140 milligrams.Another common misconception that needs mentioning is theamount of salt used by the conditioner to regenerate the system. In thepast, water conditioners used more salt to regenerate, but that was dueto old technology and standards. Water conditioners do use salt forregeneration, but the amount of salt varies by water consumption andhardness levels. Fortunately, today’s technology allows us to dispensejust the right amount of salt for maximum efficiency, based on yourindividual water consumption needs.Application Limitations• On hardness levels of 60 grains and higher, the system may notachieve a hardness of less than 1 grain; due to high Total DissolvedSolids, some bleed through is possible. Bleed through can also becaused by sodium levels higher than 1000 parts per million. In eithercase, your system can be programmed to minimize these effects. Seeyour RainSoft Dealer for details.• Chlorine or Chloramine levels on municipality treated water shouldnot exceed 4 parts per million.* When Chlorine or Chloramine levelsare 4 parts per million* or greater, it can have adverse effects on yoursystem. In applications where high levels are a concern, pre-filtrationis necessary to reduce the Chlorine or Chloramine to an acceptablelevel. See your RainSoft Dealer for details.• When this system is installed on water with Ferrous iron, also knownas clear water iron, the maximum range of removal is based on localwater conditions. The range is generally 2 to 10 parts per million.Your equipment may require special programming, along with anadditive to the brine tank, to maximize the equipment’s ability toremove iron. See your RainSoft Dealer for details.!Important Note: Oxidizing agents,such as Chlorine or Chloramine inexcess of 4 ppm, and/or Ferrousiron will foul the resin bed. Fouledresin is not eligible for warrantyreplacement.!Important Note: This system maybe in-stalled on well water ormunicipality treated watersupplies.!Important Note: Most municipalitytreated water supplies containChlorine as a disinfectant. Manymunicipalities also inject ammoniainto the water supply, creatingChloramine.Maximum disinfectant level ofChlorine or Chloramine recom-mended from the EPA.*Helpful Tip: Another commonmisconception of water treatmentsystems is the idea that soft waterwill produce clear ice cubes.Cloudy or white, hazy ice cubesare caused by air that is slowlybeing released from the waterduring the freezing process, whichhas nothing to do with the perform-ance of your system.
