Culligan knows the more informed you are about your water treatment systems, the more confident you will be about
its performance. It’s because of this and more than seventy years of commitment to customer satisfaction that Culligan is
providing this Performance Data Sheet to its customers.
NOTICE Read this Performance Data Sheet and compare the capabilities of this unit with your actual
water treatment needs. It is recommended that before purchasing a water treatment unit, you
have your water supply tested to determine your actual water treatment needs.

Contaminant Level pH Flow Rate Pressure
Barium 2.0 mg/L 7.5 + 0.5 9.0 gpm 11 (psig)
Radium 226/228 5 pCi/L 7.5 + 0.5 9.0 gpm 11 (psig)
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. Hardness test strips have been included. Additional strips are available
from your local Culligan dealer.
The Culligan High Efficiency Series 9” 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 (cal-
cium and magnesium), barium, and radium 226/228, as verified and substantiated by test data.
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 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.
