Rated Capacity at Chlorine Concentration***** of:
This system conform to NSF/ANSI 42 & 44 for the specific performance claims as verified and substantiated by
test data.
* Testing was performed using pellet grade sodium chloride as the regenerant salt.
** Efficiency rating is valid only at the lowest stated salt dosage. These softeners were efficiency rated
according to NSF/ANSI 44.
*** Extent of iron removal may vary with conditions. The capacity to reduce clear water iron is substantiated by
WQA test data. State of Wisconsin requires additional treatment if water supply contains greater than 5 ppm
clear water iron. Refer to Cleaning Iron Out of the Water Softening System section.
**** Canada working pressure limits: 1.4–7.0 kg/cm
*****Typical residential chlorine concentration is 0.5 to 1.0 ppm.
