These softeners conform to NSF/ANSI Standard 44 for specifi c performance claims.  When set at the Salt Effi cient setting, these softeners meet or exceed Std. 44 requirement for salt effi ciency.  Effi ciency claim is only 
valid at the Salt Effi cient Setting.
NOTES: For satisfactory performance, indicated fl ow rates and duration should not be exceeded.  Flow rates specifi ed are adequate for normal residential applications.  Do not use Service Flow Rate if treated water is to 
supply a geothermal heat pump, swimming pool, etc. (contact our Customer Service Department at 1-866-990-9785 before selecting equipment).  Service fl ow rates have been tested against NSF Standard 44.
