Features

  • HydroLink Plus® Wi-Fi and Smartphone App Monitoring
    HydroLink Plus® – Wi-Fi enabled technology sends continuous and excessive water use, system error, low salt and service reminder alerts, including a water-to-drain sensing alert notifying you when an excessive amount of water is going to drain.
    HydroLink® – Patented two-way remote monitoring also available.
  • Water Meter – Allowing for chemical feed dosing, flow switch operation and water use information.
  • Patented Electronics Digital Demand Module – Sophisticated, yet easy-to-use electronics capture historical usage patterns to predict future needs for precise regenerations.
  • High Quality Fit and Finish
  • Multi-Wrap Fiberglass Reinforced Resin Tank – Durable tank liner will not deteriorate, rust, or corrode.
  • Full One-Inch Riser with Self-Cleaning Distributors – One-inch diameter for increased flow rates, which ensures that household demand is adequately met. Distributors exhibit excellent flow rates and are cleaned automatically by counter-current water pressure.
  • Coconut-Shell Carbon with Lifetime Warranty – Filters the water throughout the home without compromising water flow. Reduces chlorine taste and odor, extends resin life and eliminates the need for a separate carbon filter and filter changes.
  • Patented Stratified Resin Bed with Lifetime Warranty – Layered mix of fine and standard size resin provides superior filtration and iron removal without sacrificing flow rate capability.
  • Positive-Action Brine Valve – Snap-together construction eliminates use of solvents that may contaminate water. Positive action helps prevent overfilling.

1Intermittent flow rate does not represent the maximum service flow rate used for determining the refiner’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. 2When operated at 35 psi water pressure.
3Maximum pressure for Canadian use is 7.0 Kg/cm2.
4Typical residential chlorine concentration is 0.5 to 1.0 ppm. 5From independent laboratory test data.
