These systems conform to NSF/ANSI 44 for
the specific capacity claims as verified and
substantiated by test data.
*
Testing was performed using pellet grade
sodium chloride as the regenerant salt.
** Efficiency rating is valid only at the lowest
stated salt dosage. These softeners were
efficiency rated according to NSF/ANSI 44.
*** Extent of iron removal may vary with
conditions. The capacity to reduce clear water
iron is substantiated by WQA test data. State
of Wisconsin requires additional treatment
if water supply contains greater than 5 ppm
clear water iron. Refer to Cleaning Iron Out of
the Water Softening System section.
**** Canada working pressure limits: 1.4–7.0 kg/cm

.
This model is efficiency rated. The efficiency rating is valid only at the minimum stated salt dose. The softener has a demand
initiated regeneration (D.I.R) feature that complies with specific performance specifications intended to minimize the amount
of regenerant brine and water used in its operation.
The softener has a rated salt efficiency of not less than 4,000 grains of total hardness exchange per pound of salt (based on
sodium chloride), and shall not deliver more salt than its listed rating or be operated at a sustained maximum service flow
rate greater than its listed rating. This softener has been proven to deliver soft water for at least ten continuous minutes at
the rated service flow rate. The rated salt efficiency is measured by laboratory test described in NSF/ANSI Standard 44. These
tests represent the maximum possible efficiency that the system can achieve. Operational efficiency is the actual efficiency
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 softener’s capacity.
