Hello H2O Man,
I just purchased a used Rainsoft gold series water treatment system. This one has the square salt tank, and two fiberglass tanks. I believe the first tank is a carbon filter, and the second tank which has the control head on top of it is the softener.
I have been researching all over on how to set it up and set the hardness level. I keep finding threads that ask you to email people a pdf that tells how to access the secret gold raindrop button menu which allows you to set the hardness among other things. Do you still have access to this and if so could you email it to me? My email address is [email protected]
The model # for my unit is QRS 844 SH
Serial # is 515430
manufacturer date is 01/13/03
