To cycle the RainSoft EC5 Series system, follow these steps:

1. From the home screen, press any key to access the main menu.
2. Select "START REGENERATION."
3. Press ENTER or the RIGHT button to enter the manual regeneration menu.
4. Choose one of the two options:
- "Regen Now": Highlight this option and press ENTER.
- Confirm "REGEN NOW" by pressing ENTER again when “YES” is highlighted.
5. The system will begin a 10-second countdown before starting regeneration.
6. The system enters Cycle 1 (Brine Refill), with the piston rod indicator aligned with position number 1.

The EC5 system will then proceed through the regeneration cycles automatically.

  • Page 3: Application Limitations

    Application Limitations On hardness levels of 60 grains and higher, the system may not achieve a hardness of less than 1 grain, due to high Total Dissolved Solids; some bleed through is possible. Bleed through is also caused by sodium levels higher than 1000 parts per million. In either case, the system can be programmed to minimize these effects.

    Water Flow Diagrams When servicing water treatment equipment, it is important to study the operation and flow of the valve. Service The untreated water enters the valve and flows around the piston between the number 2 and 4 seals. The water flows down the side of the valve and down through the mineral tank where the water is treated.
  • Page 26 Brine Make Up Helpful Tip: In this cycle, the system is providing treated water to the outlet. The valve rests in the Service position for 2 hours, while the water dissolves the salt in the brine tank. Backwash The piston moves slightly down and away from the 4th seal. The water Helpful Tip: In this cycle, the system is on enters the valve and flows around the 4th seal and into the outlet port.
  • Page 27 through the resin, it flows up the riser and through the center of the piston. The water flows over the top of the piston past the number 1 seal and out through the drain. See Figure 13. Slow Rinse Helpful Tip: In this cycle, the system is on After all the brine solution is pulled from the brine tank, the air check internal bypass.

    Troubleshooting Guide for the 8 Steps to Successful Service 1. Understanding the Nature of the Service Call • If the customer reports that the system is producing hard water, the problem is either mechanical or programming in nature. • If the customer describes salty water, noisy operation, the system is using too much salt, or water running to the drain, the problem is not mechanical in nature.
