The efficiency rating is valid only at the minimum salt dose. This system has a demand initiated regeneration (D.I.R.) feature that complies with specific performance specifications intended to minimize the amount of regenerant brine and water used in their operation.

Before You Start = The water softener requires a minimum water flow of 3 gallons per minute at the inlet. Maximum allowable inlet water pressure is 125 psi. If daytime pressure is over 80 psi, nighttime pressure may exceed the maximum. Use a pressure reducing valve if necessary (Adding a pressure reducing valve may reduce the flow). If your home is equipped with a back flow preventer, an expansion tank must be installed in accordance with local codes and laws.
Installation Requirements Location Requirements Consider all of the following when selecting an installation location for the water softener. = Do not locate the water softener where freezing temperatures occur. Do not attempt to treat water over 100ºF. Freezing temperatures or hot water damage voids the warranty. = To condition all water in the home, install the water softener close to the water supply inlet, and upstream of all other plumbing connections, except outside water pipes.
Installation Requirements Valve Drain Requirements 1/4” NPT Thread Barbs for 3/8” I.D. Tubing Using the flexible drain hose (included), measure and cut to the length needed. Flexible drain hose is not allowed in all localities (check your plumbing codes). If local codes do not allow use of a flexible drain hose, a rigid valve drain run must be used. Purchase a compression fitting (1/4 NPT x 1/2 in. minimum tube) and 1/2" tubing from your local hardware store. Plumb a rigid drain as needed (See Figure 6).

Installation Instructions continued from previous page 2. Visually check and remove any debris from the water softener valve inlet and outlet ports. 3. Make sure the turbine assembly spins freely in the "out" port of the valve (See Figure 10). 4. If not already done, put a light coating of silicone grease on the single bypass valve o-rings. 5. Push the single bypass valve into the softener valve as far as it will go.
Installation Instructions Step 5. Cold Water Pipe Grounding CAUTION: The house cold water pipe (metal only) is often used as a ground for the house electrical system, The 3-valve bypass type of installation, shown in Figure 8, will maintain ground continuity. If you use a plastic bypass valve at the unit, continuity is broken. To restore the ground, do the following: 1.
Installation Instructions continued from previous page bypass valve body toward the softener (See Figure 15). Improper removal may damage clips. Do not reinstall damaged clips. If removing clips... ...depressurize the plumbing, then push Bypass Valve body toward softener FIG. 15 Step 9. Add Water and Salt to the Salt Storage Tank 1. Using a container, add about three gallons of clean water into the salt storage tank. 2.
Programming the Water Softener and Filter Low Salt LED Indicator Display UP button RECHARGE button SELECT button Low Salt Light / Clean Reminder When the water softener is connected to electrical power, the light on the control panel will operate as follows: = = Light flashing, with the time of day shown in the display - The salt monitor system indicates a low salt level and needs to be set. See “Set Salt Level” on Page 14. Light flashing, with “CLEAn” flashing in the display (See Fig.
Programming the Water Softener and Filter Step 2. Set Water Hardness Number 1. Press the SELECT button once again to display a flashing “25” and the word “HARDNESS”. FIG. 19 2. Press the p UP or q DOWN buttons to set your water’s hardness number. NOTE: If your water supply contains iron, compensate for it by adding to the water hardness number. For example, assume your water is 20 gpg hard and contains 2 ppm iron. Add 5 to the hardness number for each 1 ppm of iron.
Programming the Water Softener and Filter Step 5. Set Salt Efficiency When this feature is ON, the water softener will operate at salt efficiencies of 4000 grains of hardness per pound of salt or higher (May recharge more often using smaller salt dosage but more regeneration water). The softener is shipped with this feature set OFF. 1. Press and hold the SELECT button until one of the screens in Figure 22 is displayed.
Customizing Features / Options Recharge Now At times of greater than normal water use, such as when you have guests, you could run out of treated water before the next scheduled recharge. If this happens, you may want to initiate an immediate regeneration, as follows: 1. Press and hold the RECHARGE button until the words “RECHARGE NOW" flash in the display. RECHARGE NOW initiated FIG. 25 The system enters the fill cycle of regeneration right away. “RECHARGE NOW” will flash during the regeneration.
Customizing Features / Options 3. Use the p UP or q DOWN buttons to set the length of the clean time in minutes. 4. When the desired clean time appears in the display, press the SELECT button four times to return to the normal run (time of day) screen. 12 or 24 Hour Clock All time displays are shown in standard clock time (1 to 12 AM; and 1 to 12 PM) at the “12 hr” default setting. To change this setting: 1. Press and hold the SELECT button until the screen in Figure 27 is displayed. 2.
Customizing Features / Options Power Outage Memory If electrical power to the softener is interrupted, the time display is blank, but the electronic controller keeps correct time for several hours. When power is restored, you must reset the present time only if the display is flashing. All other settings are maintained and never require resetting unless a change is desired. If the time is flashing after a long power outage, the softener continues to work as it should to provide you with soft water.
Routine Maintenance Cleaning the Nozzle & Venturi A clean nozzle & venturi (See Figure 35) is a necessity for the water softener to work properly. This small component creates the suction to move brine from the brine tank, into the resin tank. If it should become plugged with sand, silt, dirt, etc., the water softener will not work, and hard water will result.
Troubleshooting Automatic Electronic Diagnostics This water softener has a self-diagnostic function for the electrical system (except input power and/or water meter). The water softener monitors electronic components and circuits for correct operation. If a malfunction occurs, an error code appears in the display. FIG. 37 While an error code appears in the display, all buttons are inoperable except the SELECT button.
Troubleshooting Resetting to Factory Defaults To reset the electronic controller to its factory default for all settings (time, hardness, etc.): 1. Press the SELECT button and hold it until the display changes twice to show “CODE” and the flashing model code. 2. Press the p UP button (a few times, if necessary) to display a flashing “SoS”. FIG. 40 3. Press the SELECT button, and the electronic controller will restart. 4. Set the present time, hardness, etc., as described on pages 13-15.
