I have added the 'Hardness Table' below for you. You water at 17 grains/gal is considered extremely hard. Set the softener at highest setting for starters, then move back a little at a time until you notice a difference. Then hold there or close to that setting.
there is a SLEP setting BUU setting BR setting and a CAPG SETTNG any thoughts where they shoud be?
These all set the backwash and salt dosage
Do up you have the manual?
This is out of a similar model, I need any other information on the model you have
These settings are the same for you
ok, thanks for your help
