MAXIMUM EFFICIENCY

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 WaterBoss® filter can reduce this issue.
8. The appliance may be disinfected with 5.25% sodium hypochlorite, which is the active ingredient in household chlorine bleach. To disinfect the appliance, add 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.
9. 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.
10. Before putting the appliance back in service after work has been performed, turn on the nearest cold water tap until water runs clear.
11. Inspect and clean the brine cabinet and air check/draw tube assembly annually or when sediment is present in the brine cabinet.
12. 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.
13. 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, consider pre-treating 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 WaterBoss Water Filter can address these water concerns.
  • Model 900-IF (Iron Filter) — Reduces iron, manganese, hydrogen sulfide, and iron bacteria.
  • Model 900-NF (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.

*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 5 grains per gallon (86 mg/L) for every 1 ppm (1 mg/L) 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 provided to verify that your appliance is right for the job.
  • Model 950 is for municipally-supplied water without iron. Model 950 will condition water up to 35 grains of hardness per gallon (600 mg/L).
  • Model 700 will condition water for up to 70 grains of hardness per gallon (1,200 mg/L).
  • Model 900 will condition water for up to 90 grains of hardness per gallon (1,540 mg/L). (See Specifications.)
• Water Pressure — Not less than 20 psi or greater than 80 psi (1.4–5.5 bar) constant. If water pressure exceeds 70 psi (4.8 bar), a pressure regulator is recommended.
• Water Supply Flow Rate — A minimum of 2 gallons (7.6 L) for the 700 and 900 models to 3 gallons (11.4 L) 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 40° or greater than 100°F (4°–49°C).
• Drain — Drain the appliance to an appropriate drain, such as a floor drain or washer drain that will comply with all local and state 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 North America.

INSTALLATION GUIDE

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.

    3. Turn on the electricity and water supply to the water heater. For gas water heaters, return the gas cock to "On."
    4. Open a cold water tap and allow the appliance to flush for 20 minutes or until approximately 72 gallons (273 L) have passed through the appliance. This procedure is required to meet NSF requirements. Verify the flow rate on the controller, which indicates water flow. (See Figure 2)
    5. Replace the cabinet cover.

BYPASS VALVE

Your appliance is 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 is located on the main control valve. (See Figure 8) To engage the bypass, 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 (See Figure 9) 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, turn the knob slightly from the Service position toward the Bypass position.

PROGRAM CONTROLLER

This appliance features a four-button controller with an LCD display. The controller can be used to view the appliance's status, perform regenerations, and change settings. The controller must be set up correctly for the appliance to perform properly. See Figure 10.

Note: Ensure that the bottom of the controller is firmly locked onto the four tabs on the top of the drive end cap assembly. See Cabinet and Cover Assemblies diagram later in this manual.

Determine the Controller Setting Number

For municipal water, call the water department to determine the hardness and pH of your water supply.
For well water, use the hardness test strips provided with your appliance (See Figure 11), or have a sample of your untreated water tested by a water testing laboratory.

1. Test Strips — Follow the instructions on the test kits. If the color on your test strip is between two readings, use the higher number. Compare the colors as soon as you remove them from your water. This number gives the hardness in grains per gallon and parts per million (mg/L).
2. Testing Laboratory — To ensure proper settings, have a sample of your untreated water tested for iron and pH.
3. If the pH is below 7 and you have a 700 or 900 unit, call the HelpLine listed in General Information.
4. Use the following example to determine the controller setting.

Enter Your Setting Number Into the Controller

1. Press and hold the Set button for about 5 seconds until "25" displays.
2. Press the Change button until the display matches your compensated number. Once you pass "70" (models 700 and 950) or "90" (model 900), the display will reset to "03."
3. Press Set to save the hardness setting number.
4. To recheck the hardness setting number, hold down the Set button for about 5 seconds.

Note: Refer to Specifications for the maximum water hardness that your appliance can handle.

SYSTEM OVERVIEW

Optional Procedures
This section provides information on plumbing with copper fittings and with plastic pipe.

Hard Plumbing the Bypass With Copper Fittings
Do not use connection fittings for hard plumbing with 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.

1. Wrap the threads three times with 1/2-in. wide PTFE tape. Place each consecutive wrap on top of the previous wrap.
2. To prevent tearing of the tape, use PTFE 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.
3. Use a union with a threaded connection to facilitate repair of potential leaks in soldered joints.
4. 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.
5. Ensure that the copper tube is at least 4 in. (10 cm) long.
6. 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.

Plastic (PVC/CPVC) Pipe Joining Procedures
To ensure reliable joint integrity when using solvent cement for PVC/CPVC plumbing, follow these recommendations:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Joint Assembly — Working quickly, insert the pipe into the fitting socket and give a one-quarter 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.

WATER CONDITION SPECIFICATIONS

¹ The state of Wisconsin limits iron reduction claims to 5 ppm.
² Use clean white pellet, cube-style, or solar salt.

EFFICIENCY STATEMENTS

* IAPMO Unified Plumbing Code limits water supply pressure to 80 psi maximum.
This product is efficiency rated according to NSF/ANSI 44. The stated efficiencies are valid only at the specified salt dosage and flow rate.

An Efficiency-rated water softener is a Demand-initiated regeneration softener that also complies with specific performance specifications intended to minimize the amount of regenerant brine and water used in its operation. Efficiency-rated water softeners shall have a rated salt efficiency of no less than 3,350 grains of total hardness exchange per pound of salt (based on NaCl equivalency) (477 grams of total hardness exchange per kilogram of salt), and shall not deliver more salt than its listed rating.
Efficiency is measured by a laboratory test described in NSF/ANSI 44.
The test represents the maximum possible efficiency that the system can achieve. Operational efficiency is the actual efficiency achieved after the system has been installed. It is typically less than the efficiency due to individual application factors including water hardness, water usage, and other contaminates that reduce the softener's capacity.
Conforms to NSF/ASNI 44 for the specific performance claims below as verified and substantiated by test data.
