All Systems above tested at 35psi +/- 5 psi, pH of 7.5 +/- 0.5, Capacity Testing Flow Rate = 50% of the rated service flow rate for
the various size systems.
These water softener systems have been tested by WQA and conform to NSF/ANSI 44 for specific
performance claims as verified and substantiated by test data. The rated salt efficiencies above were
also determined in accordance with NSF/ANSI 44 and are only valid at the salt dosage referenced above.
An efficiency rated water softener is a demand initiated regeneration (DIR) softener which 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 that
3350 grains of total hardness exchanged per pound of salt (based on NaCl equivalency) (477 grams of
total hardness exchanged per kilogram of salt), and shall not deliver more salt than its listed rating. The
rated efficiency of the water softener, the salt dosage at that efficiency, the capacity at that salt dosage
and that of the efficiency is only valid at the stated salt dosage. Efficiency is measured by a laboratory test
described in NSF/ANSI 44. The test represents the maximum possible efficiency 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 contaminants that reduce the water softener’s capacity. These systems are not intended to be used
for treating water that is microbiologically unsafe or of unknown quality without adequate disinfection
before or after the system. Refer to the system Installation and Service Manals for set-up and programming
instructions.
