The Culligan Soft-Minder Twin Water Softeners are tested and certified by WQA against WQA S-100 for the effective reduction of
calcium and magnesium (hardness).
This softener is efficiency rated, it has a Demand Initiated Regeneration (D.I.R.) feature which complies with specific performance
specifications intended to minimize the amount of regenerant brine and water used in their operation. The softener has a rated salt
efficiency of not less than 3350 grains of total hardness exchange per pound of salt used (based on NaCl equivalency), and shall
not deliver more salt than its listed rating. The efficiency is measured by a laboratory test described in NSF/ANSI Standard 44.
This test represents the maximum possible efficiency that the system can achieve. Operational efficiency is the actual efficiency
achieved after the system has been installed. Operational efficiency 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 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 3 lb salt dosage for Soft-Minder 61 models.
