What size softener is it? There's a label on the tank somewhere and the model number is the diameter and height I.E. 0948 is a 9" x 48" tank and that says you have a 1.0 cuft softener. Then you set the salt dose for 15 lbs per cuft and do two manual regens with no water use until they are both finished. After the first one finishes, wait two hours before doing the second one.
