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.
Inspect Shipment 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. 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.
Installation Requirements LOCATION REQUIREMENTS PLUMBING CODES 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 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 COMPLETE INLET AND OUTLET PLUMBING Measure, cut, and loosely assemble pipe and fittings from the main water pipe to the inlet and outlet ports of the water softener valve. Be sure to keep fittings fully together, and pipes squared and straight. Salt Lid Be sure hard water supply pipe goes to the water softener valve inlet side.

Installation Instructions COLD WATER PIPE GROUNDING INSTALL SALT STORAGE TANK OVERFLOW HOSE 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 SANITIZE THE WATER SOFTENER / SANITIZE AFTER SERVICE If removing clips... Care is taken at the factory to keep your unit clean and sanitary. Materials used to make the unit will not infect or contaminate your water supply, and will not cause bacteria to form or grow. However, during shipping, storage, installation and operation, bacteria could get into the unit. For this reason, sanitizing as follows is suggested* when installing. ...

Programming the Water Softener STEP 2. SET WATER HARDNESS NUMBER STEP 4. SET SALT TYPE If you completed the previous step, the word “HARDNESS" should show in the display. Otherwise, press the SELECT button several times until it does. If you completed the previous step, either “NaCl” (for Sodium Chloride) or “KCl” (for Potassium Chloride) should show in the display. Otherwise, press the SELECT button several times until one of them does. FIG. 21 1.
Programming the Water Softener EXTRA RECHARGE continued from previous page 2. The salt level scale, on the brinewell inside the tank, has numbers from 0 to 8 (See Fig. 24). Observe the highest number the leveled salt is at, or closest to. Sometimes, a manually initiated recharge (regeneration) may be desired, or needed. Two examples are: = 3. Press the r UP or s DOWN buttons until the number on the screen corresponds to the salt level. At level 2 or below, the status light will flash.
Controller Features OPTIONAL SETTINGS: = SALT EFFICIENCY = MAXIMUM DAYS BETWEEN RECHARGES Displayed when efficiency is set to “ON” 12 / 24 HOUR CLOCK = BACKWASH & FAST RINSE TIMES = FIG. 30 2. Press SELECT again to display the “Set Recharge Days” screen. 1. To set any of these options, press and hold the SELECT button for 3 seconds until “000 - -” shows in the display. FIG. 28 FIG. 31 Then press (do not hold) SELECT again to display one of the “Salt Efficiency” screens shown below.
continued from previous page Controller Features FIG. 33 BACKWASH & FAST RINSE TIMES: If you experience salty tasting water after recharge, you may need to increase the backwash and fast rinse times. The cycle times during recharge are determined by the softener’s electronic controller. However, you may increase the backwash and fast rinse times, in 1 minute increments. If you wish to increase the backwash time, use the r UP or s DOWN buttons to add up to 15 minutes.
ADDING SALT Routine Maintenance BREAKING A 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. Lift the salt lid and check the salt storage level frequently.
Routine Maintenance CLEANING THE NOZZLE & VENTURI PROTECT THE WATER SOFTENER FROM FREEZING A clean nozzle & venturi (See Figure 37) 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. If the softener is installed where it could freeze (summer cabin, lake home, etc.
PROBLEM No soft water No soft water & display is blank No soft water & salt level not dropping No soft water & salt storage tank full of water, water running to drain while unit is in the soft water cycle Troubleshooting Guide CAUSE CORRECTION 1. No salt in the storage tank. Refill with salt and then use RECHARGE NOW feature. 2. Fuse blown, circuit breaker popped, or circuit switched off (See “Program Memory” on Page 14).
Troubleshooting AUTOMATIC ELECTRONIC DIAGNOSTICS 3. The letter “P” and a dash (or dashes) indicate POSITION switch operation (See Figure 40). If the letter appears, the switch is closed. If the dash shows, the switch is open. 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.
Troubleshooting RESETTING TO FACTORY DEFAULTS slow flow of water to the drain will begin. Verify brine draw from the brine tank by shining a flashlight into the brinewell and observing a noticeable drop in the liquid level. This may take 15 to 20 minutes. NOTE: Be sure water is in contact with the salt, and not separated by a salt bridge (See "Breaking A Salt Bridge" section).
