§
*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 effi-
ciency. 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 model is efficiency rated. The efficiency rating is valid only at the minimum salt dose. The softener has a demand ini-
tiated 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.
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.
