Hydrotech 7000 SXT Valve nextSand Turbidity & Sediment Filter Operation Manual - Manual (Page 3)

How Your 7000SXT Water Filter Works
Raw water enters your home through the main supply line, enters your filter, and passes downward through the media
bed. Impurities such as turbidity and sediment (nextSand filter) are removed from the water. The filtered water then
flows into your household water lines. Periodic regeneration is required to flush entrapped material from the system.
In normal operation, the Time of Day display will alternate being viewed with the Volume Remaining display. This display
will be in gallons, liters or cubic meters. 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
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.
