My sister-in-law just bought a house that has an old Rain Soft water softener in it. The only thing I can find on the head is an electronic brain. I would like to find an owner's manual, but don't know how to proceed. Can you help?
Thank you,
Terry Miller

There should be Manufacturer's sticker somewhere on the unit itself. See if you can find it. Copy the info and either Google it or call the number on the sticker. Back to you. Milo
