*Capacity to reduce clear water iron is substantiated by WQA test data. State of Wisconsin
requires additional treatment if water supply contains clear water iron exceeding 5 ppm.
**Intermittent flow rate does not represent the maximum service flow rate used for deter -
mining the softener’s rated capacity and efficiency. Continuous operation at flow rates
greater than the service flow rate may affect capacity and efficiency performance.
***Typical residential chlorine concentration is 0.5 to 1.0 ppm.
§ From independent laboratory test data.
This system conforms to NSF/ANSI Standards 42 & 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. The softener has a
demand initiated regeneration (D.I.R) feature that complies with specific performance specifications intended to mini-
mize 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 maxi-
mum 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.
While testing was performed under standard laboratory conditions, actual performance of the system may vary based
on local water conditions. This system has been tested according to NSF/ANSI Standard 42 for the reduction of
chlorine taste and odor. The concentration of the indicated substance in water entering the system was reduced to a
concentration less than or equal to the permissible limit for water leaving the system, as specified in NSF/ANSI
Standard 42.
