ADJUSTING YOUR WATER HARDNESS
The blend adjusting knob (Figure 16) gives the
ability to finely adjust hardness of the treated water
leaving the water softener. If slightly harder water
is desired than is normally delivered by the water
softener, the blend adjusting knob can divert a small
stream of hard water and blend it with the soft water
entering the home. The amount of water diverted is
controlled by turning a blend adjusting knob on the
end cap of the valve stem.
NOTE: To get full performance from your water
softener leave blending valve in the factory closed
position.
To make adjustments to water hardness:
1. Hold bypass handle to keep the valve stem
from rotating (see Figure 16). Loosen hex nut on
blend adjustment knob by turning the hex nut
counterclockwise, (see Figure 17).
2. TO INCREASE HARDNESS: With the bypass in
the service position (see Figure 16) hold the handle
to keep the valve stem from rotating and turn the
blend adjusting knob counterclockwise up to 2
turns from the closed position. It is recommended
that adjustments be made in quarter turn
increments over several weeks until the desired
hardness is achieved. NOTE: Once an adjustment
is made to the blend valve knob the change in
water hardness at the homes faucets or shower
heads may take several days to be noticed. This
delay is due to the large amounts of already
conditioned water in the pipes and water heater
that must be exchanged before a change in
hardness can be noticed. Have the water tested
to determine the actual water hardness.
3. TO DECREASE HARDNESS: With the bypass in
the service position (see Figure 16) hold the handle
to keep the valve stem from rotating and turn the
blend adjusting knob clockwise. When the knob
will not turn anymore, hard water is no longer
being blended into the soft water.
4. Once the desired hardness is achieved tighten the
hex nut (see Figure 17) clockwise until it comes in
contact with the bypass stem.
NOTE: To meet the water softener performance
specifications and reduction of barium and radium
claims the adjustable hardness must be kept in
the "OFF" position. The off position is achieved
when the blend adjusting knob is fully rotated
clockwise until it stops.

CAUTION!
serviced or disconnected from the bypass valve,
the blend adjusting knob must be turned all the
