Adjust The Blending Valves
There are two (2) valves that are adjustable to provide a blend
of RO permeate and incoming water to suit the application.

To adjust the blend:
1. Determine the desired TDS for the application.
2. Locate the two (2) Blend Valves above the filter
manifolds.
3. OPEN the RO Blend Valve fully, see Figure 15. This allows
maximum flow of the RO permeate water.
4. CLOSE the Hard Water Blend Valve, see Figure 15.
NOTE: This configuration provides only RO permeate water
with no hard water blend.
5. OPEN the Hard Water Blend Valve one (1) full rotation.
6. OPEN the Soft Water and the Hard Water Inlet Valves.
7. With the system turned ON, run water out of the Blended
Water Outlet Valve for two (2) minutes.
8. Test the TDS or check the post-filter status screen.
9. If the TDS is too high, then CLOSE the Hard Water Blend
Valve in small increments and retest. If the TDS is too
low, then OPEN the Hard Water Blend Valve in small
increments and retest. Allow water to flow for two (2)
minutes between tests.
10. When the blend is correct, mount and secure the HE-3
Processor Cover. Place the system into full operation.
