How Your High Flow 7000 SXT Series Water Softener Works
Hard water enters your home through the main supply line, enters the softener and passes down through a resin mineral
bed which softens the water. An ion exchange process takes place in which the resin beads capture and hold calcium and
magnesium, the hardness minerals, while the water takes on sodium ions. The soft water then flows into your household
water line.
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.

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.
Less than 6 minutes

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.
Control Operation During Programming
The control will only enter the Program Mode with the valve in Service. While in the Program Mode, the control will
continue 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 back-up power.
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 initiates a regeneration cycle on days that have been set to “on” at the
specified regeneration time.
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
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.
Installation Instructions
All government codes and regulations governing the installation of these devices must be observed.
CAUTION: If the ground from the electrical panel or breaker box to the water meter or underground copper pipe is tied to the
copper water lines and these lines are cut during installation of the Noryl bypass valve and/or poly pipe, an approved
grounding strap must be used between the two lines that have been cut in order to maintain continuity. The length of the
grounding strap will depend upon the number of units being installed and/or the amount of copper pipe being replaced with
poly. See Figure 1.
In all cases where metal pipe was originally used and is later interrupted by poly pipe or the Noryl bypass valve as in Figure 1
or by physical separation as in Figure 2, an approved ground clamp with no less than #6 copper conductor must be used for
continuity, to maintain proper metallic pipe bonding.
Check your local electrical code for the correct clamp and
cable size.
Figure 1
Determine the best location for your water softener,
bearing in mind the location of your water supply lines,
drain line and 120 volt AC electrical outlet. Subjecting the
softener to freezing or temperatures above 110°F (43°C)
will void the warranty.

to the O-ring to ease installation of the riser tube. DO NOT
use petroleum based lubricants as they will cause swelling of
0-rings and seals.
The softener is now charged with softening resin.
It is recommended that the softener tank now be completely
filled with water (SLOWLY) to soak the resin before startup. This will allow the media to absorb water as well as help
displace any trapped air. This will reduce the chance of backwashing resin out during startup.
Outside faucets used to water lawns and gardens should not supply softened water. A new water line is often required to
be connected to supply hard water to the inlet of the water softener and to the outside faucets. Cut the water line between
where it enters the house and before any lines that branch off to feed the hot water heater or other fixtures in the house
and as near the desired location of the water softener as possible. Install a tee fitting on the feed end of the cut pipe, and
an elbow fitting on the other end. Install piping from the tee to the inlet of the water softener and from the elbow to the
outlet of the softener. To sever the water lines which branch off to feed any outside faucets, cut the branch lines
approximately two inches from the fitting on the main water line. Install an elbow on the end of the pipe nearest the outside
faucet and a cap on the end connected to the existing water line. Install piping from the tee installed on the inlet line to the
water softener to the elbow installed on the pipe to the outside faucet. Following this procedure will result in all lines in the
house, with the exception of the outside faucets, but including the water heater and therefore the hot water lines, being
supplied with soft water.
Installation Instructions
Figure 3
Familiarize yourself with the location of the inlet, outlet and drain on the control valve. Be very careful not to get the
controls wet.
4. Attach the bypass valve to the control valve. Connect the inlet and outlet of the water softener to the plumbing in the house.
The control valve must not be submitted to temperatures above 71°C (110°F). When sweat fittings are used, to avoid
damaging the control valve, solder the threaded copper adapters to the copper pipe and then, using Teflon tape, screw the
assembly into the bypass valve.
CAUTION - do not use pipe thread compound as it may attack the material in the valve body.
Run the drain line to a floor drain or a laundry drain. Complete any necessary plumbing.
NOTE: The 1/2” nylon swivel hose barb fitting used on the 7000 DFLC elbow cannot be used on units larger than
90,000 grain. Contact Customer Service for additional information.
On twin tank units, pull the brine line through the hole in the back of the brine tank. Connect the brine line to the fitting on
the side of the valve using the nut and ferrule. Tighten snugly.
Make sure the bypass valve is in the service position.
Plug the 24-volt transformer into a 120 VAC 60 Hz outlet. This valve has five positions: 1) Backwash
2) Brine/Rinse 3) Second Backwash (not used) 4) Rapid Rinse and 5) Brine Refill. When the valve is in the Service
position, the extra cycle button (far left button as shown on Figure 4) must be pressed and held for 5 seconds before it
activates. Press and hold the extra cycle button for 5 seconds to advance the valve into the “1” Backwash position. Slowly
turn on the water supply and allow the unit to backwash until the air purges out of the tank and clears the system.
Press the extra cycle button to advance the valve to the “2” position. Press once more to advance to positions “3” then “4”.
Press once more to advance to the “5” Brine refill position. Wait until the water level reaches 6" in the brine tank. Water
can be added to the tank to speed up the filling but the valve should be in the Brine Refill position for a minimum of two
minutes to purge the air out of the injector set.
10. Press the extra cycle button to advance the valve from the Brine Fill position through service to the “2” position
Brine/Rinse position. Verify that water is being drawn from the tank. If not, repeat step 9.
11. Press the extra cycle button to advance the valve to the “4” Rapid Rinse position and allow water to run to drain for 2
12. Press the extra cycle button to advance the valve to the “5” Brine Fill position until there is 6” of water in the brine tank.
Press the extra cycle button to advance the valve back into the service position indicated by the red dot in upper left
corner of the display.
13. Put 40 kgs of crystal water softener salt in the brine tank. The unit will automatically fill to the correct level when it
Optional Sanitization Procedure: We recommend that all new water conditioners be disinfected as part of the startup.
Sanitization is achieved by the application of chlorine in the regeneration cycle of the conditioner. A liquid solution of 5.25%
sodium hypochlorite (commonly referred to as household bleach) is recommended as a suitable disinfectant. Use only
unscented products. For every cubic foot of resin in the softener, pour approximately two (2) tablespoons of sodium
hypochlorite into the brine well tube. The brine tank refill in Step 12 should add the correct amount of water to the brine tank. If
not, the water can be added manually now. Press and hold the EXTRA CYCLE button to begin a manual regeneration. Press
the EXTRA CYCLE button again to advance the valve to the Brine/Rinse position. Allow softener to complete the Brine/Rinse
cycle, then let the manual regeneration continue until the brine tank is refilled again with the correct amount of water.

Error Display Example
NOTE: Unit will flash when an error exists.
Manual Regeneration Cycle
If you run out of softened water because of inadequate regeneration frequency, inadequate reserve capacity, power
failure or unusually high water usage, you can initiate a manual regeneration simply by pressing the extra cycle button
for 5 seconds. The softener will now automatically complete a regeneration cycle and return to service. If possible, avoid
water use during the regeneration cycle.
If, once you have set your softener, you experience frequent loss of water pressure, you may have to increase the
frequency of regeneration by resetting the gallons between regeneration.
Automatic Bypass
The regeneration cycle lasts approximately 2-1/2 hours, after which soft water service will be restored. During
regeneration, hard water is automatically bypassed for use in the household. Hot water should be used as little as
possible during this time to prevent hard water from filling the water heater. This is why the automatic regeneration is set
for sometime during the night and manual regenerations should be performed when little or no water will be used in the
Safety Float
The brine tank is equipped with a safety float which prevents your brine tank from over filling as a result of a malfunction
such as a power failure.
Water Pressure
Your softener is designed to operated under normal water pressures from 20 psi to 100 psi.
New Sounds
You may notice new sounds as your water softener operates. The regeneration cycle lasts approximately 90 minutes.
During this time, you may hear water running intermittently to the drain.
Manual Bypass (Figure 5)
In case of an emergency such as an overflowing brine tank, you
can isolate your water softener from the water supply using the
bypass valve located at the back of the control.
In normal operation the bypass is open with the ON/OFF knobs in
line with the INLET and OUTLET pipes. To isolate the softener,
simply rotate the knobs clockwise (as indicated by the word
BYPASS and arrow) until they lock.
You can use your water related fixtures and appliances as the water
supply is bypassing the softener. However, the water you use will
be hard.
To resume soft water service, open the bypass valve by rotating the
knobs counter-clockwise.
Figure 5
Maintenance Instructions
Checking the Salt Level
Check the salt level monthly. Remove the lid from the cabinet or brine tank, make sure salt level is always above the
brine level (you should not be able to see water).
Adding Salt
Use only clean salt labeled for water conditioner use, such as crystal, pellet, nugget, button or solar.
The use of rock salt is discouraged because it contains insoluble silt and sand which build up in the brine tank and can
cause problems with the system’s operation.
Add the salt directly to the tank, filling no higher than the top of the brine well.
Liquid brine will irritate eyes, skin and open wounds - gently wash exposed area with
fresh water. Keep children away from your water conditioner.
Figure 6
Bridging (Figure 6)
Humidity or the wrong type of salt may create a cavity between the water and the salt.
This action, known as “bridging”, prevents the brine solution from being made, leading to
your water supply being hard.
If you suspect salt bridging, carefully pound on the outside of the plastic brine tank or
pour some warm water over the salt to break up the bridge. This should always be
followed up by allowing the unit to use up any remaining salt and then thoroughly
cleaning out the brine tank. Allow four hours to produce a brine solution, then manually
regenerate the softener.
Care of Your Softener
To retain the attractive appearance of your new water softener, clean occasionally with a mild soap solution. Do not use
abrasive cleaners, ammonia or solvents. Never subject your softener to freezing or to temperatures above 110°F (43°C).
Cleaning the Injector Assembly (Figure 7)
Sediment, salt and silt will restrict or clog the injector. A clean water supply and
pure salt will prevent this from happening.
Figure 7
Injector Cap
The injector assembly is located on the top of the control valve. This assembly
is easy to clean.
Shut off the water supply to your softener and reduce the pressure by opening a
cold soft water faucet. Remove the injector cap clip. Next remove the injector
cap. Carefully remove the assembly and disassemble as shown in Figure 7. The
injector assembly is removed from the valve body by carefully using the injector
cap clip. Note: Do not rotate the injector when removing. Carefully flush all parts.
Use a mild acid such as vinegar or Pro-Rust Out to clean the small holes in the
orifice and throat.
Cap Clip
Reassemble using the reverse procedure.
Resin Cleaner
An approved resin cleaner MUST be used on a regular basis if your water supply contains iron. The amount of resin
cleaner and frequency of use is determined by the quantity of iron in your water (consult your local representative or
follow the directions on the resin cleaner package).
