Efficiency Statement
Performance Data Sheet
These models are efficiency rated. The efficiency rating is valid only at the stated salt dose
and maximum service flow rate. They 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 3350 grains of total hardness exchange per pound
of salt (based on sodium chloride) and shall not deliver more salt than their listed ratings.
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. These
systems are not intended for use with water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after the system. For best results, use
plain, white block salt. Refer to Installation/operation manual and warranty for further
details on installation, parts and service, maintenance and further restrictions or limitations
to the use of the product.
