@H2O MAN,
Dear H2O Man,
I'm new to this site and have read a lot of your replies to other's questions. It appears that you are the one who actually knows what he's talking about. I am sending this email to ask for your help. I recently bought a used Rainsoft EC4 50CT system and have installed it. However, I have completely positioned the cart before the horse and do not have any idea on how to get the thing working. I was stupid enough to think that all I had to do was plug it in and "follow the on screen instructions" after I had the plumbing connected. I would appreciate any help you can provide regarding set up manuals, trouble shooting, ect. Thanks
