Specifications & Performance Claims
This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose. This system has a
demand initiated regeneration (D.I.R.) feature that complies with specific performance specifications intended to min-
i
mize the amount of regenerant brine and water used in their operation.
T
his water 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
s
ustained maximum service flow rate greater than its listed rating. This system 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 lab-
oratory 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.
*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.
**Capacity to reduce clear water iron is substantiated by laboratory test data. State of Wisconsin
requires additional treatment if water supply contains clear water iron exceeding 5 ppm.
This system conforms to NSF/ANSI Standard 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.
