3 Miracle Water Installation & Operation Manual
Product Specifications
These models are efficiency rated. The efficiency rating is valid only at the minimum salt dose.
These softeners have 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 their operation.
These softeners have 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 their
listed rating or be operated at a sustained maximum service flow rate greater than their listed
rating. These softeners have been proven to deliver soft water for at least ten continuous min-
utes 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.
