How Your Water Conditioner Works
Why Water Gets Hard And How It Is Softened
All of the fresh water in the world originally falls as rain, snow, or sleet. Surface water is drawn upward by the sun, forming
clouds. Then, nearly pure and soft as it starts to fall, it begins to collect impurities as it passes through smog and dust-laden
atmosphere. And as it seeps through soil and rocks it gathers hardness, rust, acid, unpleasant tastes and odors.
Water hardness is caused primarily by limestone dissolved from the earth by rainwater. Because of this, in earlier times
people who wanted soft water collected rainwater from roofs in rain barrels and cisterns before it picked up hardness from
the earth.
Some localities have corrosive water. A softener cannot correct this problem and so its printed warranty disclaims liability for
corrosion of plumbing lines, fixtures or appliances.
Iron is a common water problem. The chemical/physical nature of iron found in natural water supplies is exhibited in four
general types:
1. Dissolved Iron—Also called ferrous or “clear water” iron. This type of iron can be removed from the water by the
same ion exchange principle that removes the hardness elements, calcium and magnesium. Dissolved iron is solu-
ble in water and is detected by taking a sample of the water to be treated in a clear glass. The water in the glass
is initially clear, but on standing exposed to the air, it may gradually turn cloudy or colored as it oxidizes.
2. Particulate Iron—Also called ferric or colloidal iron. This type of iron is an undissolved particle of iron. A softener will
remove larger particles, but they may not be washed out in regeneration effectively and will eventually foul the
ion exchange resin. A filtering treatment will be required to remove this type of iron.
3. Organic Bound Iron—This type of iron is strongly attached to an organic compound in the water. The ion exchange
process alone cannot break this attachment and the softener will not remove this type of iron.
4. Bacterial Iron—This type of iron is protected inside a bacteria cell. Like the organic bound iron, it is not removed by
a water softener.
When using a softener to remove both hardness and dissolved iron it is important that it regenerates more frequently than
ordinarily would be calculated for hardness removal alone. Although many factors and formulas have been used to deter-
mine this frequency, it is recommended that the softener be regenerated when it has reached 50–75% of the calculated
hardness alone capacity. This will minimize the potential for bed fouling.
If you are operating a water softener on clear water iron, regular resin bed cleaning is needed to keep the bed from coat-
ing with iron. Even when operating a softener on water with less than the maximum of dissolved iron, regular cleanings
should be performed. Clean every six months or more often if iron appears in your conditioned water supply. Use resin bed
cleaning compounds carefully following the directions on the container.
CAUTION! Do not use where the water is microbiologically unsafe or with water of unknown quality without
adequate disinfection before or after the unit.

How a WaterGroup Mixed Bed Water Softener Works
Water softeners remove hardness in the water by exchanging particles in the water, or ions. They remove hard ions the
calcium and magnesium in the water by trading it for sodium ions producing soft water. Unlike the calcium and magnesium,
sodium stays dissolved in water and does not form a scale. Sodium also does not interfere with the cleaning action of soaps.
The sodium is released by a charged resin contained in the softener, this resin also traps the calcium and magnesium ions.
Eventually this resin releases all of its sodium and has filled up with other ions, so it then must be regenerated. Regeneration
is accomplished by washing the resin with a salt saturated brine solution that removes the calcium and magnesium while
replenishing the sodium. This is why the softener requires a brine tank and salt.
The water softener can run for days before running out of sodium, and when it does, the sodium is replenished
in only a matter of a few hours.
The mixed bed softener also has activated carbon which adsorbs unpleasant taste and odor frm water which is caused due
to chlorine and organics. In normal operation, the Time of Day display will alternate being viewed with the Volume Remaining
display. This display will be in gallons or liters. 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.
Example 833 Gallons of Treated

0 Gallons of Treated

Timer Behavior During Regeneration
In regeneration, the control will display a special regeneration display. In this display, the control will show the current
regeneration step abbreviation the valve is advancing to or has reached and the time remaining in that step. The step
abbreviation 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.
Example Less than 6 minutes

Installation Instructions
Check your water hardness. Use test strips (Part # 2793828-20) to get an estimation of water hardness and contact your lo-
cal distributor to use WaterGroup laboratory for complete water analysis free of cost and no obligation to you.
All government codes and regulations governing the installation of these devices must be observed.
.
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 main-
tain 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 plastic pipe. 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.
NOTE: Check your local electrical code for the correct clamp.

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 43°C (110°F)
will void the warranty.
2. Media Installation (When Necessary). Models including
and higher than 1.5 CF of media are shipped with sepa-
rate media in pails or boxes. Models lower than 1.5 CF of
media come loaded with media and this step can be
skipped for new installation.
a) Remove the valve from
the mineral tank.
b) Temporarily plug the open end
of the riser tube to ensure that no
resin or gravel falls down into the
distribution.
The riser (distributor) remains
inside the tank seated in the
depression at the bottom.
Plug tube with a tape.
Remove after media is loaded.
Fill support bed first. (if supplied)
The media will not always spill down
inside the tank and may need to be
swept inside.

e. Fill support bed (if supplied) first.
During the filling process, ensure the
distributor tube stays on the bottom
of the tank, reasonably centered.
Remove the tape from the distribu-
tor once media is loaded. Whenever
possible, fill the tank outdoors to
avoid problems with dust. If filling
indoors, a dust mask should be worn.
f. Unplug the riser tube, carefully posi-
tion the valve over it and turn the
valve into the threads in the fiber-
glass tank, tightening securely into
tank. Note: Ensure that the internal
O-ring in the valve fits securely over
the riser tube. Silicone grease (part #
92360) or other food grade lubricant
may be applied to the O-ring to
ease installation of the riser tube.
The large funnel (sold separately part
# 43000) makes filling the tank easier
and neater. (Or an empty 1 gallon or 4
liter container with the bottom cut out
makes a good funnel.)

The softener or filter is now charged with softening resin.
g. It is recommended that the softener or filter tank now be completely filled with water (SLOWLY) to soak the resin or filtra-
tion media 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 or filter media out of the tank during the initial backwash on startup.
3. 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.
1. Clamp Ring – The clamp ring con-
nects the control valve to the tank
and provide an easy way to discon-
nect tank during control valve servic-
ing. Make sure that the clamp ring
screw is tightened.
The “Clamp Ring” should secure the valve with the top of the flange
facing up. Please note “top” on the clamp ring.

4. Attach the bypass valve to the con-
trol valve (and yoke if plastic bypass
is used). Connect the inlet and outlet
of the water softener to the plumb-
ing in the house. The control valve
must not be submitted to tempera-
tures above 43°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.

Waste connections or drain outlet shall be designed and constructed to provide for connection to the sanitary
waste system through an air-gap of 2 pipe diameters or 1 inch (22 mm) whichever is larger.
Never insert drain line directly into a drain, sewer line, or trap. Always allow an air gap between the drain line and
the wastewater to prevent the possibility of sewage being back-siphoned into the conditioner.
6. The brine line is connected to the
safety float assembly of the brine
tank. Pull the 3/8” 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.
Remove the nut from the brine line
of the valve and push the other end
of the brine tube inside it. Make sure
that the brass insert is snugged inside
the brine tubing. The brine tubing
should pass through both plastic
inserts of the black nut.
7. Overflow Connection (Optional): In
the event of a malfunction, the brine
TANK OVERFLOW will direct “overflow”
to the drain instead of spilling on the
floor. This fitting should be installed at
the side of the cabinet or brine tank.
To connect the overflow line, drill
the hole on the side of the tank, 2 to
3 inches below from the top of the
brine tank. Insert overflow fitting (sold
separately part # 33006) into tank and
tighten with plastic thumb nut and
gasket as shown. Attach length of
1/2-inch (1.3-cm) I.D. tubing (not supplied) to fitting and run to drain. Do not
elevate overflow line higher than overflow fitting.
Do not tie into drain line of control unit. Overflow line must be a direct, sepa-
rate line from overflow fitting to drain, sewer or tub. Allow an air gap as per
drain line instructions.
5. Drain Line Connection: Using teflon
tape, screw the 1/2” hose barb into
the drain port in the valve. Attach
1/2” drain hose to the hose barb and
tighten securely with a hose clamp.
Run the drain line to a floor drain or
a laundry drain. Complete any
necessary plumbing.

Sanitization can also 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 so-
dium hypochlorite into the brine well tube. The brine tank refill step of regeneration should add the correct amount of water
to the brine tank. If not, the water can be added manually now. Press and hold the to begin a manual regeneration.
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.
NOTE: ALL STATE AND LOCAL GOVERNMENT CODES GOVERNING INSTALLATION OF THESE DEVICES MUST BE OBSERVED.

Controller Behavior
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.

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 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.

During Regeneration
Automatic Bypass
The regeneration cycle lasts approximately 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.
IMPORTANT: 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 household.
New Sounds
You may notice new sounds as your water softener operates. The regeneration cycle lasts approximately 2-1/2 hours. During
this time, you may hear water running intermittently to the drain.
Water Bypass
Manual Bypass (Figure 5A)
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 ar-
row) 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.
Stainless Steel Bypass (Figure 5B)
In normal operation the bypass lever is aligned with the inlet/outlet with the
pointer on SERVICE. To isolate the softener or filter, rotate lever counter clock-
wise until it stops and pointer indicates unit is in bypass.
You can use your water related fixtures and appliances as the water supply is
bypassing the softener and filter. However, the water you use will be hard or
untreated. To resume treated water service, open the bypass valve by revers-
ing the rotation of the lever.

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
NOTE: 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.
Bridging
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.
CAUTION! Liquid brine will irritate eyes, skin and open wounds -
gently wash exposed area with fresh water. Keep children away from
your water conditioner.
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 43°C (110°F).

Please refer to the servicing section of this manual for step by step procedure.
Not following the above will void all warranty on the control valve.
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).
