Name of Substance
USEPA Max. Contaminant Level
Barium
Radium 226/228
This system is certified for barium and radium 226/228 reduction based on hardness reduction.
It is recommended you test your water every 6 months to ensure the system is performing properly
and that hardness, and therefore barium and radium 226/228, are being reduced.
The Culligan High Efficiency Twin 12" Water Softeners with Soft-Minder® Meter are tested
and certified by WQA against NSF/ANSI Standard 372, CSA B483.1, NSF/ANSI Standard 44
for the effective reduction of hardness (calcium and magnesium), barium, and radium 226/228,
as verified and substantiated by test data. To maintain product certification and ensure uniform
performance, the product is retested on a consistent basis.

Soft-Minder® Meter are registered under Iowa Water Treatment Device Registration Number 20616.
An efficiency rated water softener is a DIR softener which also complies with specific performance specifications
intended to minimize the amount of regenerant brine and water used in its operation. Efficiency rated water softeners
shall have a rated salt efficiency of not less than 3350 grains of total hardness exchange per pound of salt (based on
NaCl equivalency) (477 grams of total hardness exchange per kilogram of salt), and shall not deliver more salt than
its listed rating. The efficiency is measured by a laboratory test described in NSF/ANSI 44. The test represents the
maximum possible efficiency the system can achieve. Operational efficiency is the actual efficiency achieved 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.
Refer to the Specifications, Familiarization and Warranty section of this Owner's Guide (P/N 01023052) for more
specific product information. To avoid contamination from improper handling and installation, your system should
only be installed and serviced by your Culligan Man. Performance will vary based on local water conditions. The
substances reduced by this system are not necessarily in your water.
Culligan water softeners are designed to work with any salt of good quality, although it is recommended that
you ask your local Culligan Man for his suggestion on the best type and grade of salt to use in this softener.
NOTICE
This softener is not intended to be used for treating water that is microbiologically unsafe
or of unknown quality without adequate disinfection before or after the system.
The efficiency rated dosage is only valid at the 7 lb. salt dosage and maximum service flow rate for 12" models.
