SPECIFICATIONS AND PERFORMANCE CLAIMS
This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose. This 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.

Y
Intermittent flow rate does not represent the maximum service flow rate used for determining the softeners rated capacity and efficien-
cy. Continuous operation at flow rates greater than the service flow rate may affect capacity and efficiency performance.
H
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.
