INSTALLATION
Water Pressure
A minimum of 20 psi (1.4 bar) of water pressure is required for
the regeneration valve to operate effectively.
Electrical Facilities
An uninterrupted alternating current (120 VAC) supply is
required. The control uses a transformer to supply 12 VDC.
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.
Outdoor Locations
When the water conditioning system is installed outdoors,
several items must be considered.
• Moisture — The system is not designed to withstand
extreme humidity or water spray from below. Examples
are: constant heavy mist, near corrosive environment,
upwards spray from sprinkler.
CAUTION
This unit is for dry location use only unless used
with a Listed Class 2 power supply suitable for
outdoor use.
• Direct Sunlight — The materials used will fade or
discolor over time in direct sunlight. The integrity of the
materials will not degrade to cause system failures. If
it is necessary to locate the system in direct sunlight, a
protective outdoor cover (P/N 61994) over the valve and
controller is necessary.
• Insects — If installing in an environment that may expose
the system to insects or other small animals, a protective
cover is required. The protective outdoor cover (P/N
61994) has been designed to keep all but the smallest
insects out of the critical areas. The cover should be
installed securely in place.
Bypass Valves
Always provide for the installation of a bypass 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°C),
and the unit cannot be subjected to freezing
conditions.
WARNING:
The system must be depressurized before
removing any connections for servicing.
Installation Instructions
1. Place the softener tank where you want to install the unit.
Make 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 a residential drain line
should be a minimum of 1/2" (13 mm). Backwash flow rates
in excess of 7 gpm (26.5 Lpm) or drain line length in excess
of 20' (6 m) require 3/4" (19 mm) drain line. Commercial
drain lines should be the same size as the drain line flow
control.
NOTE: The tank should have the distributor tube installed and
have the proper amount of regenerant in place.
4. Refer to the spec sheet for cutting height of the distributor
tube.
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. Soldering of joints near the drain port must be done prior to
connecting the Drain Line Flow Control fitting (DLFC). Leave
at least 6" (15 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. PTFE plumbing tape is the only sealant to be used on the
drain fitting.
8. Make sure that the floor is clean beneath the salt storage
tank and that the tank is level.
9. Place approximately 1" (25 mm) of water above the grid
plate. If a grid is not utilized, fill to the top of the air check
(Figure 1) in the salt tank. Do not add salt to the brine tank
at this time.
CAUTION
If grid plate is used, cut air check height even with
grid plate. This is critical on 6", 7", 8" and 9" tanks.
The brine refill water must come above the grid
plate and make contact with the salt.
10. On units with a bypass, place in bypass position. Turn on
the main water supply. Open a cold soft water tap nearby
and let run a few minutes or until the plumbing is free from
foreign material (usually solder) that may have resulted
from the installation. Once clean, close the water tap.
11. Slowly place the bypass in service position and let water
flow into the mineral tank. When water flow stops, slowly
open a cold water tap nearby and let water run until the air
is purged from the unit.
12. Plug the transformer into an electrical outlet.
NOTE: All electrical connections must be connected according
to local codes. Be certain the outlet is uninterrupted.
60002 Rev E
Figure 1 Residential Air Check Valve
Electrical Connection
The controller operates on 12-volt DC power supply. This
requires use of the supplied power adapter included with your
system.
NOTE: The power source should be constant. Be certain the
power adapter is not on a switched outlet. Power
interruptions longer than 8 hours may cause the
controller to lose the time setting. When power is
restored, the time setting must then be re-entered.

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.
1. Program the valve control according to instructions shown
in this manual.
2. Start an immediate regeneration by holding the Extra Cycle
button for five seconds. Position the valve to backwash.
Ensure the drain line flow remains steady for 10 minutes or
until the water runs clear.
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 five 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 cover.
7. Put salt in the brine tank.
NOTE: Do not use granulated or rock salt.
CONTROL FEATURES
Figure 2
Features of the SXT:
• Power backup that continues to keep time and the
passage of days for a minimum of 8 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.
• 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

CONTROL 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 feed water hardness and subtracting the
reserve. Meter Immediate systems generally do not use a
reserve volume. The 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. The system
regenerates 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 feed water hardness and
subtracting the reserve. The reserve should be set to ensure
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 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.
Manually Initiating a Regeneration
1. When the system is in service, press the Extra Cycle button
for five seconds on the main screen.
2. The control 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 and slow rinse).
4. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #3 (rapid rinse).
5. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #4 (brine refill).
6. 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. The display and motor shut
down, but it continues to keep track of the time and day for a
minimum of 8 hours.
The system configuration settings are stored in a non-volatile
memory and are stored indefinitely with or without 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.
CAUTION
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
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 set up with a sufficient reserve capacity to
compensate for regeneration delays.

SYSTEM DISINFECTION
Disinfection Of Water Softeners
The materials of construction of the modern water softener
will not support bacterial growth, nor will these materials
contaminate a water supply. During normal use, a softener
may become fouled with organic matter, or in some cases with
bacteria from the water supply. This may result in an off-taste
or odor in the water.
Some softeners may need to be disinfected after installation
and some softeners will require periodic disinfection during
their normal life.
Depending upon the conditions of use, the style of softener, the
type of ion exchanger, and the disinfectant available, a choice
can be made among the following methods.
Sodium or Calcium Hypochlorite
Application
These materials are satisfactory for use with polystyrene
resins, synthetic gel zeolite, greensand and bentonites.
5.25% Sodium Hypochlorite
These solutions are available by various sellers of household
bleach. If stronger solutions are used, such as those sold for
commercial laundries, adjust the dosage accordingly.
1. Dosage
A. Polystyrene resin; 1.2 fluid ounce (35.5 ml) per cubic
foot.
B. Non-resinous exchangers; 0.8 fluid ounce (23.7 ml) per
cubic foot.
2. Salt tank softeners
A. Backwash the softener and add the required amount
of hypochlorite solution to the well of the salt tank. The
salt tank should have water in it to permit the solution
to be carried into the softener.
B. Proceed with the normal recharge.
Calcium Hypochlorite
Calcium hypochlorite, 70% available chlorine, is available in
several forms including tablets and granules. These solid
materials may be used directly without dissolving before use.
1. Dosage
A. Two grains (approximately 0.1 ounce [3 ml]) per cubic
foot.
2. Salt tank softeners
A. Backwash the softener and add the required amount of
hypochlorite to the well of the salt tank. The salt tank
should have water in it to permit the chlorine solution to
be carried into the softener.
B. Proceed with the normal recharge.
INSTALLATION CHECKLIST
Read the owner's/installation manual?
Follow all safety guidelines in the manual?
If metal pipe was used, did you restore the electrical ground?
Securely install both drain hoses to an approved drain?
Perform a leak test?
Move the bypass valve to service?
Sanitize the softener?
Add salt pellets to the salt storage tank?
Program the control correctly to meet your needs?
Start a recharge?
CARE AND USE OF YOUR BRINE TANK
Each time the softener recharges, salty water (brine) is needed
to recondition the media in the water tank. The brine is pulled
from the salt tank at a controlled amount. If the salt tank does
not contain enough salt, the brine is weak, the media will not
fully recondition and untreated water will pass through.
You must keep salt in the tank.
The salt tank operates best when the salt level is below half-
full. If the tank is filled more than that the salt pellets may
"bridge". The salt pellets wedge against each other and do
not fall into the water at the bottom. Bridging will eventually
provide no salt to make brine. The softener will recharge but
not recondition the media. A salt bridge can be broken up using
a broom handle or similar rod. Carefully pound it into the salt
and the pellets will collapse. After loosening the salt pellets
wait 2 hours and start a regeneration. A second recharge may
be needed to fully recondition the media.
You should only use sodium chloride pellet salt for water
softeners. Other types of salt (rock or snow melting) will
contain dirt and chemicals that will affect your water softener.
Keep the brine tank covered.
Empty and clean the tank every three years.

TROUBLESHOOTING
Error Codes
NOTE: Error codes appear on the In Service display.
Error Code Error Type Cause Reset and Recovery
---0 Motor Stall /Cam
Sense Error
No state changes in the optical
sensor are detected for six
seconds.
Unplug the unit and plug back in. Allow the control to attempt to find
position again.
Verify the optical sensor is in place with the wires connected to the
circuit board. Verify the motor and drive train components are in good
condition and assembled properly. Check the valve and verify that the
piston travels freely. Replace/reassemble the various components as
necessary.
Plug the unit back in and observe its behavior. If the error reoccurs,
unplug the unit, put it into bypass and contact technical support.
---1 Motor Run-On Error
/Cycle Sense Error
An undesired optical sensor state
change occurred.
Non-critical error. Extra optical sensor pulse detected. Press any
button to clear the error. Press extra cycle button to advance motor to
clear error.
---2 Regen Failure The system has not regenerated
for more than 99 days (or 7 days if
the Control Type has been set to
Day-of-Week).
Perform a Manual Regeneration to reset the error code.
If the system is metered, verify that it is measuring flow by running
service water and watching for the flow indicator on the display. If the
unit does not measure flow, verify that the meter cable is connected
properly and that the meter is functioning properly.
Enter Master Programming Mode and verify that the unit is configured
properly, For the valve configuration. Check that the correct system
capacity has been selected, that the day override is set properly, and
that meter is identified correctly. If the unit is configured as a Day-of-
Week system, verify that at least one day is set ON. Correct the setting
as necessary.
---3 Memory Error Control board memory failure. Perform a Master Reset and reconfigure the system via Master
Programming Mode. After reconfiguring the system, step the valve
through a manual regeneration. If error continues, call technical
support.
---4 Fail Safe Error Valve has failed to find position in
one minute.
Unplug the unit and plug it back in. If error continues, call technical
support.
