Specifications & Performance Claims This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose. The softener 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 its operation.

Packing List The parts required to assemble and install the water softener are included with the unit. 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.

Plan Your Installation CHECK YOUR WATER PRESSURE BEFORE INSTALLING For your water softener to work properly, incoming water pressure in your house pipes must be no lower than 20 pounds per square inch (psi). The highest allowable pressure is 125 psi. If pressure is above 125 psi, buy and install a pressure reducing valve in the pipe supplying water to the softener’s inlet. NOTE: If water pressure during the day is 100 psi or more, pressure during the night may go above 125 psi.
Installation INSTALL SINGLE BYPASS VALVE (cont.) ASSEMBLE INLET AND OUTLET PLUMBING Before installing the bypass valve and/or installation adaptors, make sure that the turbine and support are firmly in place inside the softener valve’s outlet port. Measure, cut (thread if needed) and put together all pipe and fittings up to the main water pipe. Make sure that the incoming water supply pipe goes to the valve inlet side. CAUTION: Never solder fittings while connected to nonmetallic parts.
Installation CONNECT THE VALVE DRAIN HOSE Take a length of 3/8” inside diameter drain tubing (supplied) and attach one end to the drain fitting (see Fig. 11). Use a tube clamp from the parts bag to hold it in place. Put the other end of the tubing over a floor drain, into a laundry tub, standpipe, or other suitable drain. Check your local codes. Leave an air gap of about 1-1/ 2'' between the end of the hose and the drain. This gap is needed so you don’t get a backflow of sewer water into the softener.
Installation LEAK TEST To check for leaks, complete the following steps: CAUTION: To avoid water or air pressure damage to softener inner parts, and to flush pipe chips or other residue from the water pipes, be sure to do the following steps exactly as instructed. 1. Fully open two nearby cold water faucets downstream from the softener. 2. Place bypass valve(s) in “bypass” position (see Figures 12 & 13). On a single valve, slide the stem inward to bypass.
Installation METAL WATER PIPE GROUNDING IMPORTANT: This water softener has a non-metallic valve system. Installing it on metal plumbing will break electrical continuity, which may interrupt grounding for the home. You must restore electrical continuity in your metal plumbing system. If you installed a 3-valve bypass system (Fig. 13), electrical continuity will be maintained. If you installed the non-metallic bypass valve (Fig.
Programming the Softener SET SALT LEVEL button TANK LIGHT button Display Set Salt Level UP button SELECT button SALT SALT LEVEL ALARM Select press for tonight Low Salt hold for immediate REGENERATION button LOW SALT indicator PROGRAM THE SOFTENER When the transformer is plugged into the electrical outlet, the model code (350) and a test number (example: J3.0), are briefly shown in the display. Then the words “PRESENT TIME” appear and 12:00 PM begins to flash.
Programming the Softener SET RECHARGE (REGENERATION) START TIME If you completed the previous step, the words “RECHARGE TIME" should show in the display. Otherwise, press the SELECT button several times until they do. Figure 19 1. The softener’s default recharge start time is 2:00 AM. This is normally a time of day when water is not being used in the household. Hard water bypasses the softener if the household draws water during the recharge cycle.
Sanitizing the Softener SANITIZE THE WATER SOFTENER 1. Open salt lid, remove the brinewell cover and pour about 3 oz. (6 tablespoons) of household bleach into the softener brinewell. Replace the brinewell cover. 2. Make sure the bypass valve(s) is in the “service” (open) position. 3. Start a recharge: Press the REGENERATION button and hold for 3 seconds, until “RECHARGE”, “Serv” and “Fill” begin to flash in the display. This recharge draws the sanitizing bleach into and through the water softener.
Controller Features EXTRA RECHARGE 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. You can start a regeneration immediately, or you can set the controller to regenerate at the next preset recharge time (2:00 AM, or as set).
Controller Features OPTIONAL SETTINGS: = SALT EFFICIENCY = CLEAN FEATURE = CLEAN FEATURE MINUTES = MAXIMUM DAYS BETWEEN REGENERATIONS = 97% FEATURE = 12 / 24 HOUR CLOCK = 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.
Controller Features 4. Press SELECT again to display the “Recharge Days” screen. Default Display Example: Set to 4 days maximum between regenerations Figure 28 MAXIMUM DAYS BETWEEN REGENERATIONS: The electronic controller automatically determines regeneration frequency. This provides the greatest operating efficiency and, under most conditions this feature will be left in its default mode. However, you can set this feature to force a regeneration every set number of days.
Controller Features TANK LIGHT To turn on the light inside the salt storage tank, press the TANK LIGHT button on the faceplate. Press this button again to turn the light off. It will also turn off automatically after 15 minutes. Tank Light Icon Figure 33 WATER FLOW THROUGH THE SOFTENER If soft water is in use, the water flow bars continually scroll across the display. The bars scroll slowly when water flow is slow, and move faster as water flow increases.
Care of Your Water Softener SALT BRIDGE Sometimes, a hard crust or salt “bridge” forms in the brine tank. It is usually caused by high humidity or the wrong kind of salt. When the salt “bridges,” an empty space forms between the water and the salt. Then, salt will not dissolve in the water to make brine. Without brine, the resin bed is not recharged and hard water will result. If the storage tank is full of salt, it is difficult to tell if you have a salt bridge. A bridge may be underneath loose salt.
Service Information TROUBLESHOOTING If your water softener does not work properly, make the following easy checks. Often, you will find what is wrong yourself and you won’t have to call and wait for service. If you do not find anything wrong while making the checks, and your softener still does not work properly, call your Sears Service Department. PROBLEM CAUSE CORRECTION No soft water No salt in the storage tank.
Service Information MANUALLY INITIATED ELECTRONIC DIAGNOSTICS 1. To enter diagnostics, press the SELECT button and hold for three seconds. The display will change to show turbine count, valve cycle position, and position switch status (open or closed).
Service Information MANUAL ADVANCE REGENERATION CHECK This check verifies proper operation of the valve motor, brine tank fill, brine draw, regeneration flow rates, and other controller functions. Always make the initial checks first, and perform the manually initiated electronic diagnostics. NOTE: The display must show a steady time (not flashing). If an error code shows, first press the SELECT button to enter the diagnostic display. 1. Press the REGENERATION button and hold in for 3 seconds.
