This product is efciency rated according to NSF/ANSI 44. The stated efciencies are valid
only at the specied salt dosage and 7.0 gpm (26.5 L/min):
An efciency-rated water softener is a demand-initiated regeneration softener that
also complies with specic performance specications intended to minimize the
amount of regenerant brine and water used in its operation.
Efciency-rated water softeners shall have a rated salt efciency 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.
Efciency is measured by a laboratory test described in NSF/ANSI 44. The test represents
the maximum possible efciency that the system can achieve. Operational efciency is
the actual efciency achieved after the system has been installed. It is typically less than
the efciency due to individual application factors including water hardness, water
usage, and other contaminates that reduce the softeners’ capacity.
