Start-Up Instructions
The water softener should be installed with the inlet, outlet, and drain connections made in accordance with the
manufacturer’s recommendations, and to meet applicable plumbing codes.
Turn the manual regeneraton knob slowly in a clockwise direction until the program micro switch lifts on top of
1.
the rst set of pins. Allow the drive motor to move the piston to the rst regeneration step and stop. Each time
the program switch position changes, the valve will advance to the next regeneration step. Always allow the
motor to stop before moving to the next set of pins or spaces..
NOTE: For electronic valves, please refer to the manual regeneration part of the timer operation
section. If the valve came with a separate electronic timer service manual, refer to the timer operation
section of the electronic timer service manual.
Position the valve to backwash. Ensure the drain line ow remains steady for 10 minutes or until the water
2.
runs clear (see above).
Position the valve to the brine / slow rinse position. Ensure the unit is drawing water from the brine tank (this
3.
step may need to be repeated).
Position the valve to the rapid rinse position. Check the drain line ow, and run for 5 minutes or until the water
4.
runs clear.
Position the valve to the start of the brine tank ll cycle. Ensure water goes into the brine tank at the desired
5.
rate. The brine valve drive cam will hold the valve in this position to ll the brine tank for the rst regeneration.
Replace control box cover.
6.
Put salt in the brine tank..
7.
.
NOTE: Do not use granulated or rock salt.

Timer Operation
Meter Immediate Control
A meter immediate control measures water usage and regenerates the system as soon as the calculated system
capacity is depleted. The control calculates the system capacity by dividing the unit capacity (typically expressed
in grains/unit volume) by the feedwater hardness and subtracting the reserve. Meter Immediate systems generally
do not use a reserve volume. However, in twin tank systems with soft-water regeneration, the reserve capacity
should be set to the volume of water used during regeneration to prevent hard water break-through. A Meter
Immediate control will also start a regeneration cycle at the programmed regeneration time if a number of days
equal to the regeneration day override pass before water usage depletes the calculated system capacity.
Meter Delayed Control
A Meter Delayed Control measures water usage and regenerates the system at the programmed regeneration
time after the calculated system capacity is depleted. As with Meter Immediate systems, the control calculates the
system capacity by dividing the unit capacity by the feedwater hardness and subtracting the reserve. The reserve
should be set to insure that the system delivers treated water between the time the system capacity is depleted
and the actual regeneration time. A Meter Delayed control will also start a regeneration cycle at the programmed
regeneration time if a number of days equal to the regeneration day override pass before water usage depletes
the calculated system capacity.
Time Clock Delayed Control
A Time Clock Delayed Control regenerates the system on a timed interval. The control will initiate a regeneration
cycle at the programmed regeneration time when the number of days since the last regeneration equals the
regeneration day override value.
Day of the Week Control
This control regenerates the system on a weekly schedule. The schedule is dened in Master Programming by
setting each day to either “off” or “on.” The control will initiates a regeneration cycle on days that have been set to
“on” at the specied regeneration time.
Control Operation During Regeneration
During regeneration, the control displays a special regeneration display. In this display, the control shows the
current regeneration step number the valve is advancing to, or has reached, and the time remaining in that step.
The step number that displays ashes until the valve completes driving to this regeneration step position. Once all
regeneration steps are complete the valve returns to service and resumes normal operation.
Pressing the Extra Cycle button during a regeneration cycle immediately advances the valve to the next cycle
step position and resumes normal step timing.
Control Operation During Programming
The control only enters the Program Mode with the valve in service. While in the Program Mode, the control
continues to operate normally monitoring water usage and keeping all displays up to date. Control programming is
stored in memory permanently
, eliminating the need for battery backup power.
Manually Initiating a Regeneration
When timer is in service, press the Extra Cycle button for 5 seconds on the main screen.
1.
The timer advances to Regeneration Cycle Step #1 (backwash), and begins programmed time count down.
2.
Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #2 (brine draw & slow rinse).
3.
Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #3 (rapid rinse).
4.
Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #4 (brine rell).
5.
Press the Extra Cycle button once more to advance the valve back to in service..
6.
NOTE: If the unit is a lter or upow, the cycle step order may change..
NOTE: A queued regeneration can be initiated by pressing the Extra Cycle button. To clear a queued regener-
ation, press the Extra Cycle button again to cancel. If regeneration occurs for any reason prior to the delayed
regeneration time, the manual regeneration request shall be cleared.

Timer Operation
Control Operation During A Power Failure
The SXT includes integral power backup. In the event of power failure, the control shifts into a power-saving
mode. The control stops monitoring water usage, and the display and motor shut down, but it continues to keep
track of the time and day for a minimum of 48 hours.
The system conguration settings are stored in a non-volatile memory and are stored indenitely with or without
line power. The Time of Day ashes when there has been a power failure. Press any button to stop the Time of
Day from ashing.
If power fails while the unit is in regeneration, the control will save the current valve position before it shuts down.
When power is restored, the control will resume the regeneration cycle from the point where power failed. Note
that if power fails during a regeneration cycle, the valve will remain in it’s current position until power is restored.
The valve system should include all required safety components to prevent overows resulting from a power
failure during regeneration.
The control will not start a new regeneration cycle without line power. If the valve misses a scheduled
regeneration due to a power failure, it will queue a regeneration. Once power is restored, the control will initiate
a regeneration cycle the next time that the Time of Day equals the programmed regeneration time. Typically,
this means that the valve will regenerate one day after it was originally scheduled. If the treated water output is
important and power interruptions are expected, the system should be setup with a sufcient reserve capacity to
compensate for regeneration delays.
