A Fully Automatic, Chemical-Free Whole-House Problem Water Filtration System

EC5 OxyTech Features

Immediate Condition Response: Push any button and the EC5 OxyTech wakes up to display the system status with any applicable instructions or messages.

Power Outage Recovery: If power is lost during the regeneration process, the EC5 OxyTech will automatically recover and complete the process once power is restored. This feature ensures that filtered water is always available.

Service Required Alarm: The EC5 OxyTech supports an alarm that informs the user of service required or other regular maintenance.

Large Interactive Display: The EC5 OxyTech provides easy-to-read and understand system information via a two-line LCD display. Messages scroll across the display identifying the menu being accessed.

Information Center: Simple access to the EC5 OxyTech’s Information Center menu provides the customer with information about their system, water quality, usage profile and general support data. Aids both the customer and the dealer when troubleshooting the unit.

Filter Media

The EC5 OxyTech media is a special blend of four minerals, each with specific removal characteristics. This mineral maintains a long material life with a relatively low attrition loss and a wide temperature performance range.

How the EC5 OxyTech Works

Step 1: Water enters the EC5 OxyTech compressed aeration chamber. As the water passes through the compressed air chamber, the water becomes highly oxygenated. As the water continues to flow though the tank, the oxygenated water converts the iron, manganese and hydrogen sulfide from dissolved minerals and gasses to physical particles.

Step 2: The highly oxygenated water then flows through the multimedia filter bed where iron, manganese and elemental sulphur are trapped in the multimedia bed.

Step 3: At pre-determined intervals the system will backwash and reduce all contaminants from the filter media.

Application Limitations

pH – The influent water must be between 6.8–9.0.

Iron – Maximum of 10 ppm of ferrous (clear water) and/or ferric (red water) iron. If iron is present, the pH should be below 8.5. Higher pH conditions may cause the formation of colloidal iron, which is very difficult to remove.

Iron Bacteria – If iron bacteria are present, frequent service may occur and the life of the system may be limited. By properly controlling the iron bacteria with chlorine or other approved methods for bacterial reduction, the system will function properly.

Hydrogen Sulfide – Maximum of 10 ppm.

Manganese – Limit 2.0 ppm; amounts over 2.0 ppm may gradually prevent iron removal. For optimum manganese reduction, the pH should be between 8.0–9.0. If iron is also present, the pH should be below 8.5.

Chlorine – The presence of chlorine in the raw water supply should be limited to a maximum of 1.0 ppm.

Organic Matter (Tannins) – The presence of organics above 2.0 ppm may hinder the operation of the system.

Maintenance Requirements

The filtering media will eventually become exhausted or consumed and will need replacement. The replacement schedule will depend on the incoming water quality and the amount of water you use. Your local authorized RainSoft dealer can provide you with replacement schedules based on your water-using habits and your incoming water quality.

The regeneration valves are designed to last a lifetime. Annual cleaning or replacement of internal parts will be necessary since these parts are exposed to untreated water. Your water quality and the amount of regenerations will affect this schedule. Your dealer is knowledgeable in different water qualities and the necessary parts required in completing this service.

Upon installation, your system will be programmed with an alarm to remind you when either of the above services are required.

Operating Features

  • New LCD display prompts the user with easy-to-understand system information and messages.
  • Control automatically compensates and adjusts for daylight saving time.
  • The system maintains time up to 1 week without a battery backup in case of a power outage. Program settings are maintained indefinitely, eliminating the need to reprogram.

CALIFORNIA RESIDENTS: Water treatment devices sold to retail consumers in California accompanied by certain health claims must be certified by the California Department of Health Services. The EC5 OxyTech series is not certified by the State of California for the purpose of making health claims.
