Inspect Shipment The parts required to assemble and install the unit are included in a bag. Thoroughly check the water softener for possible shipping damage and parts loss. Also inspect and note any damage to the shipping carton. Remove and discard (or recycle) all packing materials. To avoid loss of small parts, we suggest you keep the small parts in the parts bag until you are ready to use them.
Specifications & Performance Claims This model is efficiency rated. 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 120ºF. 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 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 REGENERATION button Display SELECT button UP button press for tonight Select hold for immediate Set Salt Level Water Use STATUS LIGHT (see below) SET SALT LEVEL button Status Light When the Morton Water Softener is connected to electrical power, the status light on the control panel will be on or flashing, as follows: = = = = = Light on steady (not flashing) - The system has power applied and does not require any attention.
Programming the Water Softener continued from previous page NOTE: Press buttons and quickly release to slowly advance the display. Hold the buttons down for fast advance. 2. When the correct time is displayed, press the SELECT button, and the display will change to show the “Hardness” screen. Step 2. Set Water Hardness Number If you completed the previous step, the word “HARDNESS" should show in the display. Otherwise, press the SELECT button several times until it does. 1.
Extra Recharge Controller Features Sometimes, a manually initiated recharge (regeneration) may be desired, or needed. Two examples are: = = You have used more water than usual (guests visiting) and you may run out of soft water before the next automatic regeneration. You did not add salt to the softener before it ran out. Add salt to the softener before regenerating.
Controller Features Optional Settings: = Salt Efficiency = Clean Feature = Clean Feature Minutes = 97% Feature = 12 / 24 Hour Clock = Gallons / Liters = Maximum Days Between Regenerations = Backwash & Fast Rinse Times 1. To set any of these options, press and hold SELECT for 3 seconds until “000” shows in the display. Then press (do not hold) SELECT again to display one of the “Salt Efficiency” screens shown below. 2. Press SELECT again to display one of the “Clean” screens shown below. FIG.
Controller Features 97% Feature: The 97% Feature can save salt and water by regenerating when 97% of the softener’s capacity has been used up. With this feature ON, the regeneration can occur at any time (whenever the system has reached 97% of its capacity). The default is OFF. If this feature is desired, turn it on by pressing the r UP button. 5. Press SELECT again to display the “12 or 24 hr” screen.
Controller Features Water Flow Through the Softener To view the flow rate through the softener in liters (or gallons) per minute, press the WATER USE button. If soft water is in use, the flow rate will be displayed to the nearest tenth of a liter (or gallon). The display will show “0” when all faucets and water using appliances are off. FIG.
Controller Features 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 43) 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. 45 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 the flashing model code. 2. After observing fill, press the RECHARGE button to move the softener’s valve into the brine position. A slow flow of water to the drain will begin.
