ESD 500ecowater series • water softener

Bypass Valve (optional) Brass-free and lead-free bypass valve lets you manually bypass the system.

Patented Electronic Digital Demand ModuleSolid-state electronics record usage patterns and controlregeneration frequency based on predicted needs.

Time KeeperPermanent program memory with capacitor-backed time retention.Maintains time for at least 6 hours in case of power loss.

Multi-Wrap Fiberglass Reinforced Resin TankDurable fiberglass-wrapped tank liner, doesn’t deteriorate, rust or corrode.

Self-Cleaning DistributorsDistributors exhibit excellent flow rates and are cleanedautomatically by counter-current water pressure.

Positive-Action Brine ValveSnap-together construction eliminates use of solvents that maycontaminate water. Positive action helps prevent overfilling.

Energy Efficient 24-Volt Transformer Simplifies installation, maintenance and reduces electrical hazards.

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 ratesgreater 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 containsgreater than 5 ppm clear water iron.3When operated at 35 psi water pressure4Maximum pressure for Canadian use is 7.0 Kg/cm2
