Installation Instructions
WATER PRESSURE: A minimum of 20 psi (1.3 bar) of water pressure is required for regeneration valve to operate effectively.
ELECTRICAL FACILITIES: An uninterrupted alternating current (A/C) supply is required. Note: Other voltages are available.
Please make sure your voltage supply is compatible with your unit before installation.
EXISTING PLUMBING: Condition of existing plumbing should be free from lime and iron buildup. Piping that is built up heavily
with lime and/or iron should be replaced. If piping is clogged with iron, a separate iron filter unit should be installed ahead of
the water softener.
LOCATION OF SOFTENER AND DRAIN: The softener should be located close to a drain to prevent air breaks and back flow.
BY-PASS VALVES: Always provide for the installation of a by-pass valve if unit is not equipped with one.
CAUTION: Water pressure is not to exceed 125 psi (8.6 bar), water temperature is not to exceed 110°F (43.3°C), and the unit
cannot be subjected to freezing conditions.
Installation Instructions
1.
Place the softener tank where you want to install the unit making sure the unit is level and on a firm base.
2.
During cold weather, the installer should warm the valve to room temperature before operating.
3.
All plumbing should be done in accordance with local plumbing codes. The pipe size for residential drain line should be
a minimum of 1/2” (12.7 mm). Backwash flow rates in excess of 7 gpm (26.4Lpm) or length in excess of 20’ (6 M) require
3/4” (99 mm) drain line. Commercial drain lines should be the same size as the drain line flow control.
4.
Refer to the dimensional drawing for cutting height of the distributor tube. If there is no dimensional drawing, cut the
distributor tube flush with the top of the tank.
5.
Lubricate the distributor O-ring seal and tank O-ring seal. Place the main control valve on tank.
Note: Only use silicone lubricant.
6.
Solder joints near the drain must be done prior to connecting the Drain Line Flow Control fitting
(DLFC). Leave at least 6” (15.2 cm) between the DLFC and solder joints when soldering pipes
that are connected on the DLFC. Failure to do this could cause interior damage to the DLFC.
7.
Teflon tape is the only sealant to be used on the drain fitting. The drain from twin tank units may
be run through a common line.
8.
Make sure that the floor is clean beneath the salt storage tank and that it is level.
9.
Place approximately 1” (2.54 cm) of water above the grid plate. If a grid is not utilized, fill to the
top of the air check in the salt tank. Do not add salt to the brine tank at this time.
10. On units with a by-pass, place in by-pass position. Turn on the main water supply. Open a cold
soft water tap nearby and let run a few minutes or until the system is free from foreign material
(usually solder) that may have resulted from the installation. Once clean, close the water tap.
11. Slowly place the by-pass in service position and let water flow into the mineral tank. When water
flow stops, slowly open a cold water tap nearby and let run until the air is purged from the unit.
12. Plug unit into an electrical outlet. Note: All electrical connections must be connected according to
local codes. (Be certain the outlet is uninterrupted).

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.
NOTE: The valve control may need to reset to the home position when it is powered up. If it does, the motor will
run and the display will read “UD SYNC” to show that it is synchronizing the upper drive. When this is complete,
the motor will stop and the display will show the time of day.
1. Press the extra cycle button and hold it for five seconds to trigger a manual regeneration and advance the
valve to the first regeneration position. Pressing the extra cycle button while the unit is in a regeneration cycle
will cause the valve to advance to the next position.
2. Position the valve to backwash. Ensure the drain line flow remains steady for 10 minutes or until the water
runs clear (see above).
3. Position the valve to the brine / slow rinse position. Ensure the unit is drawing water from the brine tank (this
step may need to be repeated).
4. Position the valve to the rapid rinse position. Check the drain line flow, and run for 5 minutes or until the water
runs clear.
5. Position the valve to the start of the brine tank fill cycle. Ensure water goes into the brine tank at the desired
rate. The brine valve drive cam will hold the valve in this position to fill the brine tank for the first regeneration.
6. Replace control box cover.
7. Put salt in the brine tank.
NOTE: Do not use granulated or rock salt.

Features of the SXT:
• Power backup that continues to keep time and the passage of days for a minimum of 48 hours in the event of
power failure. During a power outage, the control goes into a power-saving mode. It does not monitor water
usage during a power failure, but it does store the volume remaining at the time of power failure.
• Settings for both valve (basic system) and control type (method used to trigger a regeneration).
• Day-of-the-Week controls.
• While in service, the display alternates between time of day, volume remaining or days to regeneration, and
tank in service (twin tank systems only).
• The Flow Indicator flashes when outlet flow is detected.
• The Service Icon flashes if a regeneration cycle has been queued.
• A regeneration can be triggered immediately by pressing the Extra Cycle button for five seconds. During
regeneration, the user can force the control to advance to the next cycle step immediately by pressing the
Extra Cycle button.
• The Parameter display shows the current Cycle Step (BW, BF, RR, etc) during regeneration, and the Data
display counts down the time remaining for that cycle step. While the valve is transferring to a new cycle step,
the display will flash.
• The Parameter display will identify the destination cycle step (BW, BF, RR, etc) and the Data display will read
“----”. Once the valve reaches the cycle step, the display will stop flashing and the Data display will change to
the time remaining.
Setting the Time of Day
1. Press and hold either the Up or Down buttons until the programming icon replaces the service icon and the
parameter display reads TD.
2. Adjust the displayed time with the Up and Down buttons.
3. When the desired time is set, press the Extra Cycle button to resume normal operation. The unit will also
return to normal operation after 5 seconds if no buttons are pressed.

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 defined in Master Programming by
setting each day to either “off” or “on.” The control will initiate a regeneration cycle on days that have been set to
“on” at the specified 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 flashes 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.

Timer Operation
Manually Initiating a Regeneration
1. When timer is in service, press the Extra Cycle button for 5 seconds on the main screen.
2. The timer advances to Regeneration Cycle Step #1 (backwash), and begins programmed time count down.
3. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #2 (brine draw & slow rinse).
4. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #3 (backwash).
5. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #4 (rapid rinse).
6. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #5 (brine refill).
7. Press the Extra Cycle button once more to advance the valve back to in service.
NOTE: If the unit is a filter or upflow, the cycle step order may change.
NOTE: A queued regeneration can be initiated by pressing the Extra Cycle button. To clear a queued regeneration, press the Extra Cycle button again to cancel. If regeneration occurs for any reason prior to the delayed
regeneration time, the manual regeneration request will be cleared.
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 configuration settings are stored in a non-volatile memory and are stored indefinitely with or without
line power. The Time of Day flashes when there has been a power failure. Press any button to stop the Time of
Day from flashing.
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 overflows 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 sufficient reserve capacity to
compensate for regeneration delays.
