Features

  • Patented Electronics Digital Demand Module – Sophisticated, yet easy-to-use electronics capture historical usage patterns to predict future needs for precise regenerations.
  • Time Keeper – Permanent program memory with capacitor-backed time retention. Maintains time for at least 6 hours in case of power loss.
  • Multi-Wrap Fiberglass Reinforced Resin Tank – Durable fiberglass-wrapped tank liner, doesn’t deteriorate, rust, or corrode.
  • Self-Cleaning Distributors – Distributors exhibit excellent flow rates and are cleaned automatically by preventing clogging.
  • Brine Valve – Controls water flow in and out of salt tank. Features automatic shut-off to prevent overfilling.
  • Bypass Valve (optional) – Brass-free and lead-free bypass valve lets you manually bypass the system.
  • Energy Efficient Power Supply – Simplifies installation, maintenance and reduces electrical hazards.
  • Barium and Radium Reduction, and Low Lead Content – This softener has been tested and certified by NSF International against NSF/ANSI Standard 44 for the reduction of Barium and Radium 226/228, hardness reduction and efficiency and NSF/ANSI 372 for low lead content.

1Intermittent flow rate does not represent the maximum service flow rate used for determining the softener’s rated capacity and efficiency. Continuous operation at flow rates greater than the certified flow rate
may affect capacity and efficiency performance. The validity of these flow rates is verified by NSF. 2Increased amounts of clear water iron can reduce softeners efficiency. Refer to owner’s manual for details.
Wisconsin requires additional treatment if water supply contains greater than 5 pm clear water iron. 3When operated at 35 psi water pressure. 4Maximum pressure for Canadian use is 7.0 Kg/cm2.
