Hydrotech 9100 SXT Valve Meter Initiated Water Softener - Manual (Page 2)

How Your 9100SXT Downflow Water Conditioner Works
Hard water enters your home through the main supply line, enters the softener and passes down through a resin mineral
bed which softens the water. An ion exchange process takes place in which the resin beads capture and hold calcium and
magnesium, the hardness minerals, while the water takes on sodium ions. The soft water then flows into your household
water line.
In normal operation, the Time of Day display will alternate being viewed with the Volume Remaining display then the Tank
in Service. This display will be in gallons, liters or cubic meters. The tank in service will be shown as U-I or U-2. As treated
water is used, the Volume Remaining display will count down from a maximum value to zero or (---).Once this occurs, a
regeneration cycle will be initiated at the Set Regeneration Time. Water flow through the valve is indicated by the Flow
Indicator that will flash in direct relationship to flow rate.
Example 833 Gallons of Treated
Water Remaining
Tank In Service
0 Gallons of Treated
Water Remaining
Control Operation During Regeneration
In regeneration, the control will display a special regeneration display. In this display, the control will show the current
regeneration step number the valve is advancing to or has reached and the time remaining in that step. The step
number displayed will flash until the valve has completed driving into this regeneration step position. Once all
regeneration steps have been completed, the valve will return to Service and resume normal operation.
Example Less than 6 minutes
remaining in Regen
Step Rapid Rinse
Pushing the Extra Cycle Button during a regeneration cycle will immediately advance the valve to the next cycle step
position and resume normal step timing.

• Capacities are based on two tanks of resin. Eg: 9100SXT-30 set at 10lb/cf salt setting would provide
27,000 grains of hardness removal for one tank.
