Rain Soft Gold Series Water Treatment System Installation & Service Manual (w/ Advanced Settings)
I have a Rain Soft Gold Series Water Softener that we bought approx. 2008. I found an A2K Thread on this subject and joined A2K specifically to to answer the many inquiries about this, but there are no REPLY buttons in the thread even though the last post was in 2020. (
https://able2know.org/topic/139017-1) I contacted Rain Soft this year (2021) and told them that I needed a copy of the Gold Series ADVANCED SETTINGS instructions, because there are no longer any RainSoft technicians in my region of the US. This is what they sent me. For everyone wanting access to the Advanced Settings instructions for your RainSoft Gold Series Water Softener, they are contained within this RainSoft Technicians/Installers Service Manual PDF. I posted the pdf on line and you can view, go full screen and read, and download it here at this link. I guess they decided it's no longer a company secret since they sent it to me, so here it is for everyone that has been searching for a copy. Finally....
