Getting Maximum Efficiency From the Appliance
To achieve the maximum benefit and performance from
this appliance, familiarize yourself with this manual and
the appliance.
1. The salt level should always be at least 1/3 full.
Refill the salt when the level drops below the water
level in the brine cabinet. A resin cleaner can be
used on a monthly basis. Clean white pellet,
cube-style, or solar salt is recommended. Do not
use rock salt.
Caution: Do not mix different types of salt.
2. You may switch to a salt substitute (such as
potassium chloride) in place of water conditioner
salt at any time. If potassium chloride is used in
place of salt, increase your hardness setting by
12% (multiply by 1.12). See Setting the Controller.
Caution: Do not use potassium chloride if your
water contains iron and/or manganese.
3. Should your electricity be off for any reason check
your controller for the correct time and reset as
necessary (See Advanced Customer Settings).
4. Program the appliance to regenerate at a time
when the water is not being used. If there is more
than one appliance, allow two hours between each
regeneration.
5. Protect the appliance, including the drain line, from
freezing.
6. Adhere to all operational, maintenance, and
placement requirements.
7. If dirt, sand, or large particles are present in the
water supply, the appropriate filter can eliminate
this problem.
8. If your appliance runs out of salt:
A. Open the salt lid and add salt.
B. Wait two hours, then press and hold the R
(Regenerate) button for 5 seconds.
C. Regeneration is complete after approximately
12 to 45 minutes, and the appliance is returned
to Service mode.
9. The appliance may be disinfected with 5.25%
sodium hypochlorite, which is the active ingredient
in household chlorine bleach. To disinfect the
appliance, add 118 mL (4.0 fluid ounces) of chlorine
bleach solution to the brine well of the brine cabinet.
The brine cabinet should have water in it. Start a
manual regeneration.
10. The bypass valve (located on the main control
valve) enables you to bypass the appliance if any
work is being performed on the appliance, well
pump, or plumbing. See Bypass Valve. Use Bypass
mode also for watering plants or lawns with
untreated water. If your appliance is equipped with
a bypass, turn the knob to the Bypass position to
bypass the appliance. Turn it to the Service position
to restore soft water to your home.
11. Before putting the appliance back in service after
work has been performed, turn on the nearest cold
water tap until water runs clear.
12. Inspect and clean the brine cabinet and air
check/draw tube assembly annually or when
sediment is present in the brine cabinet.
13. Model 950 contains redox media and activated
carbon media. These have a finite life and will
eventually require replacement if the advertised
performance capabilities of this device are to be
maintained.
14. This product is certified for barium and radium
226/228 reduction according to NSF/ANSI
Standard 44. Any Bypass system must be
completely in the Service position to ensure
maximum barium and radium 226/228 reduction.

Checklist Before Installation
Refer to this checklist before installation.
Water Quality—If the water supply contains sand, sulfur, bacteria, iron bacteria, tannins, algae, oil, acid, or other unusual
substances, pre-treat the water to remove these contaminants before the water supply enters the appliance, unless the
appliance is represented as being capable of treating these contaminants in its specifications.
The appropriate water filter below can address these water shortcomings.
•Model 900IF (Iron Filter)–Reduces iron, manganese, hydrogen sulfide, and iron bacteria.
•Model 900CF (Carbon Filter)–Reduces chlorine taste and odor.
•Model 900NF (Acid Neutralizing filter)–Adjusts low pH water to a non-corrosive state.
Iron—A common problem found in many water supplies is iron. It is important to know what type of and how much iron is
in the water supply.
Iron Type
Description
Ferrous Iron* (sometimes
called clear water or
dissolved iron)
Only type of iron that can be treated with a water softener
Ferric Iron
Insoluble and the particles can eventually foul a resin bed. It should be filtered out before the
water reaches the softener
Organic Iron or Bacterial
Iron
Attached to other organic compounds in the water. Additional treatment is needed to remove
this type of iron
Colloidal Iron
Not dissolved, yet stays in suspension. A softener cannot remove this type of iron
* If the water supply contains ferrous iron, a commercially available resin bed cleaner should be used every six months. Follow the instructions on
the container. You should also increase your water hardness setting by 86 mg/L (5 grains per gallon) for every 1 mg/L (1 ppm) of ferrous iron.
Water Characteristics—Models 700, 900, and 950 require a pH of 7 or above to function properly. An iron test to
determine iron levels is also necessary. The 900-NF Acid Neutralizing Filter adjusts pH levels of 6.3 or above.
Water Hardness—Double check hardness of water with test strips, if provided, to verify that your appliance is right for
the job.
•Model 700 will condition water for up to 1,197 mg/L (70 grains of hardness per gallon).
•Model 900 will condition water for up to 1,539 mg/L (90 grains of hardness per gallon). (See Specifications.)
•Model 950 is FOR MUNICIPALLY-SUPPLIED WATER without iron. Model 950 will condition water up to 599 mg/L
(35 grains of hardness per gallon).
Water Pressure—Not less than 1.4 bar (20 psi) or greater than 8.3 bar (120 psi) constant. If water pressure exceeds
4.8 bar (70 psi), a pressure regulator is recommended.†
Water Supply Flow Rate—A minimum of 7.6 L (2.0 gallons) for the 700 and 900 models to 11.4 L (3 gallons) for the
950 model per minute or equal to the backwash flow rate of the particular model is recommended. For the purposes of
plumbing sizing, only the rated service flow rate and corresponding pressure loss may be used. Prolonged operation of a
water conditioner at flow rates exceeding the tested service flow rate may compromise performance.
Water Temperature—Not less than 4°C (40°F) or greater than 49°C (120°F).
Drain—Drain the appliance to an appropriate drain, such as a floor drain or washer drain that will comply with all
applicable plumbing codes. To prevent back-siphoning, provide an adequate air gap or a siphon break. See Installation
Steps and Start-Up Procedures.
Electricity—The transformer supplied is for a standard 115 volt, 60-cycle AC outlet for locations in North America or 220
volt, 50-cycle AC outlet for locations outside of North America.
†Applies to U.S. plumbing codes. Check the plumbing codes of your country.

Owner’s Manual and Installation Guide 11/13/2020 8
Installation Steps and Start-Up Procedures
The water softener is capable of treating a combination of undesirable constituents (such as iron, dirt, sediment, chlorine,
and/or lead) in water. See Specifications for the capabilities of your appliance. Install, set up, and use the appliance within
the operating limits outlined in this manual. Failure to comply with these specifications may decrease the effectiveness of
the backwash and cause control valve malfunction. The water softener, like any other appliance, requires correct
installation and setting for optimum performance.
Each water treatment appliance includes 2.4 m (8 feet) of drain line and a drain fitting.
Step 1 Prepare the Placement Area
A. Make sure the placement area is clean.
B. Turn off the electricity and water supply to the water heater. For gas water heaters, turn the gas cock
to “Pilot.”
C. Examine the inlet plumbing to ensure that the pipe is not plugged with lime, iron, or any other
substance. Clean or replace plugged plumbing.
Note: A minimum 3/4-inch pipe is required between the pressure tank and the appliance for the
appliance to function properly.
D. Make sure the inlet/outlet and drain connections meet the applicable plumbing codes.
E. Check the arrows on the bypass valve to ensure that the water flows in the proper direction.
See Bypass Valve.
Caution: Do not plumb the appliance in backward.

Installation Steps and Start-Up Procedures, Cont.
G. For most installations, install the appliance after the pressure tank and any water filter appliance or
water meter and before the water heater unless otherwise recommended.
Water Heaters: If less than 3 m (10 feet) of pipe connects the water treatment appliance(s) to the
water heater, install a check valve between the water treatment appliance and the water heater as
close to the water heater as possible. Ensure that the water heater has an adequately rated
temperature and pressure safety relief valve.
H. For outside installations, the appliance should be enclosed so it is protected from the weather.
Step 2 Test Your Water
A. Remove any packaging or installation materials from the brine cabinet.
B. Contact your water treatment specialist or obtain a report on your water’s quality. Optionally, use the
test strips if they have been provided.
Step 3 Turn Off Water Supply
A. Turn off the water supply.
B. Open the hot and cold water taps to depressurize the lines.
Step 4 Connect Water Lines
Your appliance may come with a built-in bypass valve.
Step 4A: With Bypass Valve
A. Lift and remove the valve cover.

Installation Steps and Start-Up Procedures, Cont.
Step 4B: Without Bypass Valve (3/4-inch or 1-inch
Adapter) Using Copper Fittings
When preparing the male threaded fittings of the I/O
adapter, use the following guidelines to avoid damage to the
plastic pipe threads.
A. Wrap the threads three times with 1/2-inch wide Teflon
tape. Place each consecutive wrap on top of the
previous wrap.
B. To prevent tearing of the tape, use Teflon paste on the
first two male threads only. The paste lubricates the tape
and fills the small void areas that might exist between the
threads. When the joint is complete, there will be a small
bead of sealant at the fitting interface, which indicates a
properly joined connection.
C. Use a union with a threaded connection to facilitate
repair of potential leaks in soldered joints.
D. Prepare the copper tail assemblies in advance to enable
them to cool prior to final assembly. Advance preparation
and cooling will prevent heat damage to the plastic pipe
threads of the adapter.
E. Ensure that the copper tube is at least 10 cm
(4 inches) long.
F. Turn the fitting counterclockwise until you feel the
threads engage and then tighten to prevent cross
threading. Do NOT overtighten the fittings.
Caution: Do NOT allow heat from the torch to
transfer to the plastic valve component, which could
be damaged.

Step 4C: Without Bypass Valve (3/4-in or 1-in Adapter) Using Plastic (PVC/CPVC) Pipe
Joining Procedure
To ensure reliable joint integrity when using solvent cement for PVC/CPVC plumbing, follow these
recommendations:
A. Cutting—The pipe must be cut square to allow for the proper interfacing of the pipe end and the
fitting socket bottom. Use a wheel cutter, miter saw, or a ratchet shear for best results.
B. Deburring and Beveling—Use a knife, plastic pipe deburring tool, or a file to remove burrs from the
end of the pipe. Be sure to remove all burrs from the inside as well as the outside of the pipe.
Remove all loose plastic debris since it could clog the injector. All pipe ends should be beveled to
permit easier insertion of the pipe into the fitting. Failure to bevel the pipe end may cause a “wiping”
effect in the fitting where the cement is forced to the end of the fitting socket. This creates a
weak joint.
C. Test Dry Fit of the Joint—Tapered fitting sockets are designed so that an interference fit should
occur when the pipe is inserted about one-third to two-thirds of the way into the socket. Occasionally,
when pipe and fitting dimensions are at the tolerance extremes, it will be possible to fully insert dry
pipe to the bottom of the fitting socket. When this happens, a sufficient quantity of cement must be
applied to the joint to fill the gap between the pipe and fitting.
D. Inspection, Cleaning, and Priming—Inspect the inside of the pipe and fitting sockets and remove
dirt, grease, or moisture with a clean dry cloth. If wiping fails to clean the surfaces, use a chemical
cleaner. Check for possible damage such as splits or cracks and replace if necessary. Use purple
primer to penetrate and soften the bonding surfaces of the PVC or CPVC pipe and fittings. Proceed
without hesitation to the cementing procedure while the primed surfaces are still wet.
E. Application of Solvent Cement—Apply the solvent cement evenly and quickly around the outside of
the pipe while the primer is still wet. Apply a light coat of cement evenly around the inside of the fitting
socket. Do not allow excess cement to “puddle” in the fitting. Apply a second coat of cement to the
pipe end.
F. Joint Assembly—Working quickly, insert the pipe into the fitting socket and give a 1/4-turn of the
pipe or fitting while pushing toward the fitting stop. This action will evenly distribute the cement. Do
NOT continue to rotate the pipe or fitting after the stop has been reached. Hold the joint tightly
together for about 15 seconds to prevent the pipe from “creeping” out of the fitting. A good joint will
have sufficient cement to make a small bead all the way around the outside of the fitting hub. The
joint should not be disturbed immediately after the cementing procedure. Allow adequate time for the
joint to cure properly. Exact drying time is hard to predict because of environmental variables. Follow
the recommended joint curing times on the primer and cement container labels.

Installation Steps and Start-Up Procedures, Cont.
Step 5 Connect Gravity Overflow Connection
The overflow line drains away excess water should the tank
fill with too much water or the appliance malfunction.
A. Attach the gravity overflow connection elbow and check
that it is in the down position. (See Figure 4.)
B. Connect 1/2-inch I.D. tubing (size cannot be reduced)
between the overflow fitting and a suitable floor drain,
laundry tub, or other suitable waste receptor. This tubing
is not supplied with the appliance. Ensure that the
overflow line ends at a drain that is at least 8 cm
(3 inches) lower than the bottom of the overflow fitting.
Maintain a minimum of 5 cm (2-inch) air gap. The
gravity line cannot be run overhead.
Step 6 Connect Drain Line
The drain line carries away the backwash water as part of
the regeneration cycle.
A. Screw the drain fitting (See Figure 5) into the drain end
cap until fewer than three threads are visible. To prevent
leakage, wrap the threads on the drain fitting three times
with 1/2-inch wide Teflon tape, or use plumber’s putty.
B. Connect the drain line to the drain end cap
(See Figure 5) with a minimum 5/8-inch I.D. tubing
(supplied). The size cannot be reduced.
C. Route the drain line to a floor drain, laundry tub, or other
suitable waste receptor. Maintain a minimum 5 cm
(2-inch) air gap between the drain line and the flood
level rim of the waste receptor to prevent
back-siphoning. This drain line should make the shortest
run to the suitable drain.
D. The drain line may be elevated up to 2.4 m (8 feet) from
the discharge on the appliance as long as the water
pressure in your system is 2.8 bar (40 psi) or more.
E. If the drain line is 7.6 m (25 feet) or longer, increase the
drain line to 3/4-inch I.D. The end of the drain line must
be equal to or lower in height than the control valve.
Caution: The drain line must not be kinked, crimped,
or restricted in any way.

E. Adjust the blending valve if it is being used.
F. Replace the valve cover.

Owner’s Manual and Installation Guide 11/13/2020 15
Bypass Valve
Your appliance may be equipped with a bypass valve. The bypass valve can
isolate the appliance should the appliance malfunction or leak. It can also
permit the use of untreated water for watering plants, shrubs, or lawns.
The bypass valve is located on the main control valve. See Figure 9. To
engage the bypass valve, turn the knob to the Bypass position. The
appliance will be bypassed and all water to the home is raw, untreated water.
To prevent untreated water from entering the home, water should not be
used inside the home when the appliance is in Bypass position. Ensure that
the appliance is returned to Service position when the appliance is repaired
or the use of untreated water is complete by turning the knob to Service.
To blend hardness back into the water using the bypass valve, turn the knob
slightly from the Service position toward the Bypass position.
Figure 9: Bypass Valve
Blending Valve
The 3/4-inch or 1-inch I/O may come with a blending valve.
In some situations, a blending valve may be desired. The amount of
hardness blended back into the water line is determined by the hardness of
the incoming water and the setting of the blending valve. Where extremely
hard water is present, the blending valve may only need to be “cracked”
open. Where the incoming water has relatively low levels of hardness, the
blending valve will need to be opened further.
The blending valve is located between the input and output connections on
the top of the 3/4-inch or 1-inch I/O adapter. See Figure 10. It is adjusted by
placing a flat blade screwdriver in the slot provided and turning clockwise to
open. Total movement of the blending valve from full closed to full open is
1/4 revolution. Precise setting of the blending valve will require “trial and
error” testing. The initial setting should be conservative. Because of the
blending valve’s ease of access and adjustment, you can increase or
decrease the setting according to your preference over a period of time.
Use of the blending valve is not recommended where objectionable
concentrations of ferrous iron or sediment are present. Because the blending
valve is mixing “raw” water with softened, any ferrous iron or sediment in the
“raw” water will also be blended and reintroduced into the softened
water line.
Note: If the appliance is installed for barium and/or radium reduction, the
blending valve must remain in the fully closed position at all times.

(700 and 900 only)
Activates/deactivates the powerClean™ feature, which is a service/maintenance step for water supplies
that have an excessive amount of iron. “powerClean™” will display when this feature is activated. The
appliance will regenerate every other day with 2.3 kg (5 lb) of salt. Leave the powerClean™ feature on for a
minimum of two weeks. The frequent regeneration will eliminate iron buildup in the resin bed. The use of
salt with an iron cleaning agent or iron out cleaner is recommended for continuous use as a preventive
measure against iron fouling of the resin bed. Use this feature every six months as a part of your routine
maintenance procedure to ensure a long service life for your water treatment appliance
Note: To deactivate the powerClean™ feature, press the button.

Setting the Controller
Step 1 Determine the Controller Hardness Setting Number
A. For municipal water, call the water department or your water treatment specialist, and they will
determine the hardness and pH of your water supply.
B. For well water, a water analysis should be taken in order to make sure your controller is set properly,
or obtain your hardness setting from your water treatment specialist.
•If the pH is below seven and you have a 700 or 900 unit, contact your water treatment specialist.
(See General Information).
C. Use the following example to determine the controller setting.
Your Water
Metric Example
English Example
Enter hardness mg/L (grains per gallon)
342
20
If your water contains 3 mg/L (3 ppm) iron, add 258 (15)*
+258
+15
The sum is your controller setting number
600**
35
* Increase your water hardness setting by 86 mg/L (5 gpg) for every 1 mg/L (ppm) of ferrous iron.
** The hardness you enter is multiplied by 10, therefore you will enter “60” as the hardness setting.
Step 2 Enter Your Setting Number Into the Controller
Note: You cannot set the controller while the appliance is
regenerating.
A. Press and hold the P button for about 5 seconds until a 2- or
3-digit number and “mg/L x 10” or “gpg” displays. This
number is the current hardness setting.
B. Press the C button until the display matches your
compensated number. Once you pass 120 mg/L x 10
(70 gpg) for models 700 and 950 or 154 mg/L x 10 (90 gpg)
for model 900, the display will reset to 05 mg/L x 10 (03 gpg).
Note: Refer to Specifications for the maximum water
hardness that your appliance can handle.
C. Press P to save the hardness setting number.
D. To recheck the hardness setting number, hold down the
P button for about 5 seconds.
