*Salt dosages can be set to maintain desired efficiencies or changed to auto adjusting, salt-efficient demand, or boiler operation. See manual for details. **Grains capacity is for counter-current regeneration sizing purposes. The actual capacity could be 5% 10% greater than shown for each salt dosage.
The optional adapters provide for direct connection of 1.5" copper tube to the 1" service valve.
