SOFTENER SPECIFICATIONS
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 Culligan Mark 100 water softeners are tested and validated by WQA against ANSI/NSF Standard 44 for the effective reduction of
calcium and magnesium (hardness) along with Barium and Radium 226/228*.
Refer to the Specifications, Familiarization, and Warranty sections 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.
