*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 adaptors provide for direct connection of 1.5" copper tube to the 1" service valve.
All specifications listed are for a SINGLE unit operation.
