Specifications & Performance Claims
*
Capacity to reduce clear water iron is substantiated by laboratory test data. State of Wisconsin
requires additional treatment if the water supply contains clear water iron exceeding 5 ppm.
**Intermittent flow rate does not represent the maximum service flow rate used for determining
the softener’s rated capacity and efficiency. Continuous operation at flow rates greater than
the service flow rate may affect capacity and efficiency performance.
This system conforms to NSF/ANSI 44 for the specific performance claims as verified and
substantiated by test data.
Variable Salt Dose:
The salt dose is selected by the electronic controls at regeneration time
based on the amount needed.

This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose and rated service flow.
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.
This softener has a rated softener efficiency of not less than 3,350 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 tests
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 rated efficiency, due to individual application factors including water hardness, water usage, and other
contaminants that reduce a softener's capacity.
