Specifications and Performance Claims
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.

substantiated by test data.
*
Testing was performed using pellet grade
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.
