STARTUP 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.
1. Turn the manual regeneraton knob slowly in a clockwise
direction until the program micro switch lifts on top of the
first set of pins. Allow the drive motor to move the piston
to the first 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.
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.
• The Parameter Display displays 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. During regeneration,
the user can force the control to advance to the next cycle
step immediately by pressing the extra cycle button.
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.
