Specifications and Performance Claims.
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.
