* Meets California efficiency requirements of 4000 grains exchanged per pound of salt used. Efficiency is only
certified at the low salt dosage and was determined in accordance with NSF/ANSI 44.
** Two (2) Tanks
*** Peak flow rates are not the maximum service flow rate used to determine rated capacities and efficiency - continuous
operation at flow rates greater than the max service flow may affect capacity and efficiency performance.
Sodium Information: Systems using sodium chloride for regeneration will add sodium to the water. The
amount of sodium added is proportionate to the amount of hardness removed. People who are on sodium-
restricted diets should consider the added sodium as part of their overall sodium intake.
