This model is efficiency rated. The efficiency rating is valid only at the minimum stated salt dose.
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.
The softener has a rated salt efficiency of not less than 4,000 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 test 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 efficiency, due to individual application factors including water hardness, water usage,
and other contaminants that reduce the softener’s capacity.
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. While testing was performed under standard laboratory
conditions, actual performance of the system may vary based on local water conditions.
