This product is efficiency rated according to NSF/ANSI 44. The stated efficiencies are valid
only at the specified salt dosage and 7.0 gpm (26.5 L/min):
An efficiency-rated water softener is a demand-initiated regeneration softener that
also complies with specific performance specifications intended to minimize the
amount of regenerant brine and water used in its operation.
Efficiency-rated water softeners shall have a rated salt efficiency of not less than
3,350 grains of total hardness exchange per pound of salt (based on NaCI equivalency)
(477 grams of total hardness exchange per kilogram of salt), and shall not deliver
more salt than its listed rating.
Efficiency is measured by a laboratory test described in NSF/ANSI 44. The test represents
the maximum possible efficiency that the system can achieve. Operational efficiency is
the actual efficiency achieved after the system has been installed. It is typically less than
the efficiency due to individual application factors including water hardness, water
usage, and other contaminates that reduce the softeners’ capacity.
