These softeners conform to NSF/ANSI 44 for the specifi c performance claims as verifi ed and substantiated by test data. These models are effi ciency rated. The effi ciency rating is valid only
at the stated salt dose and maximum service fl ow rate. They have a demand initiated regeneration (D.I.R.) feature that complies with specifi c performance specifi cations intended to minimize
the amount of regenerant brine and water used in their operation. These softeners have a rated softener effi ciency 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. The rated salt effi ciency is measured by laboratory tests described in NSF/ANSI Standard 44. These
tests represent the maximum possible effi ciency that the systems can achieve. Operational effi ciency is the actual effi ciency after the system has been installed. It is typically less than the
effi ciency 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/opera-
tion manual and limited warranty for further details on installation, parts and service, maintenance and further restrictions or limitations to the use of the product.
