PLEASE NOTE: On page nine of this manual you will find important maintenance procedures for
the continued proper operation of your unit. These M ST be performed regularly for your
guarantee to remain valid.

How Your 9100SXT Downflow Water Conditioner 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 then the Tank
in Service This display will be in gallons, liters or cubic meters The tank in service will be shown as U-I or U-2 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
Water Remaining
Tank In Service
0 Gallons of Treated
Water Remaining
Control Operation Durin Re eneration
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
Example Less than 6 minutes
remaining in Regen
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 Durin Pro rammin
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 feed water 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 feed water 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 Durin 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

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
Check your local electrical code for the correct clamp and
cable size
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
Media Installation (When Necessary)
• Remove the valve from the mineral tank
• Temporarily plug the open end of the riser tube to ensure
that no resin or gravel falls down into the distribution
• Fill mineral tank one quarter full of water to protect
distribution during gravel installation
• Slowly and carefully add the gravel support bed and the
softener or filtration media leveling each layer as it is
placed into the tank
• Unplug the riser tube, carefully position the valve over it and turn the valve into the threads in the fiberglass tank,
tightening securely into tank Note: Ensure that the internal O-ring in the valve fits securely over the riser tube
Silicone grease (#13691) or other food grade lubricant may be applied to the O-ring to ease installation of the riser
tube DO NOT use petroleum based lubricants as they will cause swelling of O-ring seals
• The softener or filter is now charged with softening resin
• It is recommended that the softener or filter tank now be completely filled with water (SLOWLY) to soak the resin or
filtration 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
2 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
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
5 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
6 On twin tank units, 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
7 Make sure the bypass valve is in the service position
8 Plug the 24-volt transformer into a 120 VAC 60 Hz outlet This valve has four positions: 1) Backwash 2) Brine/Rinse
3) Rapid Rinse and 4) 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
9 Press the extra cycle button to advance the valve to the “2” position Press once more to advance to the “3” position
Press once more to advance to the “4” 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 “3” Rapid Rinse position and allow water to run to drain for
2 minutes
12 Press the extra cycle button to advance the valve to the “4” 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
regenerates
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

Manual Re eneration 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
The softener will now automatically complete a regeneration cycle and return to service If possible, avoid water use
during the regeneration cycle
Once you have set your softener and 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
household
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 (1 4 atm) to 100 psi (8 2 atm)
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
Manual Bypass (Fi ure 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

Maintenance Instructions
Checkin 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)
Addin 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
Caution
Liquid brine will irritate eyes, skin and open wounds - gently wash exposed area with fresh water Keep children away
from your water conditioner
Brid in (Fi ure 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)
Cleanin the Injector Assembly (Fi ure 7)
Sediment, salt and silt will restrict or clog the injector A clean water
supply and pure salt will prevent this from happening
The injector assembly is located on the right side 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 Using a screwdriver, remove the two
screws holding the injector cover to the control valve body Carefully
remove the assembly and disassemble as shown in Figure 7 The
injector orifice is removed from the valve body by carefully turning it
out with a screwdriver Remove the injector throat the same way
Carefully flush all parts including the screen Use a mild acid such as
vinegar or Pro-Rust Out to clean the small holes in the orifice and
throat
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)
