Blending Valve
The 3/4-inch or 1-inch I/O Adapter Assembly may come with a blending valve.
In some situations, a blending valve may be desired. The amount of hardness blended back into the water line
is determined by the hardness of the incoming water and the setting of the blending valve. Where extremely
hard water is present, the blending valve may only need to be “cracked” open. Where the incoming water has
relatively low levels of hardness, the blending valve will need to be opened further.
The blending valve is located between the input and output connections on the top of the 3/4-in or 1-in I/O
Adapter Assembly. See Figure 18. It is adjusted by placing a flat blade screwdriver in the slot provided and
turning clockwise to open. Total movement of the blending valve from full closed to full open is 1/4 revolution.
Precise setting of the blending valve will require “trial and error” testing. The initial setting should be
conservative. Because of the blending valve’s ease of access and adjustment, you can increase or decrease
the setting according to your preference over a period of time.
Use of the blending valve is not recommended where objectionable concentrations of ferrous iron or sediment
are present. Because the blending valve is mixing “raw” water with softened, any ferrous iron or sediment in the
“raw” water will also be blended and reintroduced into the softened water line.
Note:
If the appliance is installed for barium and/or radium reduction, the blending valve must remain in the fully
closed position at all times.
