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 Twin 10” Water Softeners with Aqua-Sensor® Sensing Device 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.
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 neces-
sarily 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 6lb. salt dosage and maxmum service flow rate for 10” models.
