Rainsoft Gold System

A friend gave me a working AQC 50CV Softner and a RFC 150P Y Acid Neutralizer that have not been used for the last two years. Both units were new in 2006 and I have downloaded the owner's manuals. I am very capable of hooking this system up but am looking for some advice. I already know I have an elevated clear water iron level and low PH and will be getting my water tested before installing. Will this system effectivly remove iron? Should I replace the media in the Neutralizer? How can I reprogram the Softener myself? I have searched everywhere and cannot find the "Secret Rainsoft Programming Manual". I have self performed all maintenence on my house for the last 25 years and refuse to have some rip-off rep come in to press a few buttons. Any help is appreciated..........
