The Latest Technology for Water Treatment

1

HydroLinkPlus® Wi-Fi and Smartphone App Monitoring

HydroLinkPlus® – 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.

2

Patented Electronics Digital Demand Module

Sophisticated, yet easy-to-use electronics capture historical usage patterns to predict future needs for precise regenerations.

3

High Quality Fit and Finish

including a dampened hinge salt cover

4

Multi-Wrap Fiberglass Reinforced Resin Tank

Durable tank liner will not deteriorate, rust, or corrode.

5

Washed Quartz Underbedding

Helps provide a cleaner, more thorough regeneration of the resin.

6

Patented Stratified Resin Bed

Layered mix of fine and standard size resin provides superior filtration and iron removal without sacrificing flow rate capability.

7

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.

8

Positive-Action Brine Valve

Snap-together construction eliminates use of solvents that may contaminate water. Positive action helps prevent overfilling

1 Intermittent flow rate does not represent the maximum service flow rate used for determining the conditioner’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.

2 Increased amounts of clear water iron can reduce conditioners efficiency. Refer to owner’s manual for details. Wisconsin requires additional treatment if water supply contains greater than 5 ppm clear water iron.

3 When operated at 35 psi water pressure.

4 Maximum pressure for Canadian use is 7.0 Kg/cm2
