Safety Guides Follow the installation instructions carefully. (Failure to install the unit properly voids the warranty.) Before you begin installation, read this entire manual. Then, obtain all the materials and tools you will need to make the installation. Check local plumbing and electrical codes. The installation must conform to them. Use only lead-free solder and flux for all sweat-solder connections, as required by state and federal codes. Use care when handling the unit.
ed. A water softener removes the hardness minerals to eliminate these problems, and others. Sodium Information: Water softeners using sodium chloride (salt) for regeneration and add sodium to the water. Persons on sodium restricted diets should consider the added sodium as part of their overall intake. 2. IRON in water is measured in parts per million (ppm). The total* ppm of iron, and type or types*, is determined by chemical analysis.
Assembly 1. Miracle Water models are factory assembled. During installation, remove the Salt Hole Cover. Set aside to prevent damage. Check the brinewell to be sure it is secured and vertical (see Figure 1). Slide Faceplate Cover forward to expose back valve assembly. 2. Lift the brine valve out of the brinewell. Be sure the float stem is parallel to stand tube so seals will seat properly during operation. Replace the brine valve in the brinewell bottom and install the Brinewell Cover. 3.
Planning Installation Inlet - Outlet Plumbing Options • ALWAYS INSTALL either a single bypass valve (included) or a 3 valve bypass system (not included). Bypass valves allow you to turn off water to the softener for repairs if needed, but still have water in house pipes. • Use 3/4” (minimum) pipe and fittings. • Use sweat copper... or, threaded pipe... or, PVC plastic pipe... or, other approved plumbing.
Other Requirements • A 120V-60Hz, grounded electrical outlet (continuously ‘‘live’’) is needed within 10’ of the unit. • A drain is needed for regeneration discharge water. A floor drain, close to the unit, is preferred. A laundry tub, standpipe, etc., are other drain options.
*VALVE DRAIN OPTIONS: Flexible drain hose is not allowed in all localities (check your plumbing codes). For a rigid valve drain run, cut the barbed section off the drain fitting for access to the 1/4” pipe threads. Then plumb a rigid drain as needed (see Figure 4). Select Installation Location Consider all of the following when selecting an installation location for the unit.
Installation Step 1. Turn Off Water Supply 1. Close the main water supply valve, near the well pump or water meter. 2. Shut off the electric or fuel supply to the water heater. 3. Open all faucets to drain all water from the house pipes. Step 2. Move the Unit into Place Move the unit into installation position. Set it on a solid, smooth and level surface. If needed, place the unit on a section of plywood, a minimum of 3/4” thick. Then, shim under the plywood to level the unit, see Figure7.
Visually check and remove any foreign materials from the valve inlet and outlet ports. If not already done, put a light coating of silicone grease or Vaseline on the bypass valve o-rings. Push the bypass valve into the softener valve as far as it will go. Snap the 2 large holding clips into place, from the top down as shown in Figure 8. CAUTION: Be sure the clips snap firmly into place so the bypass valve will not pull out. Step 3.
Step 5. Cold Water Pipe Grounding WARNING: 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. 2, will maintain ground continuity. If you use a plastic bypass valve at the unit, continuity is broken. To restore the ground, do the following. Install a #4 copper wire across the removed section of main water pipe, securely clamping at both ends, see Figure 9 (parts not included).
Step 8. Pressure Testing for Leaks To prevent excessive air pressure in the unit and plumbing system, do the following steps EXACTLY in order. 1. Fully open two or more softened cold water faucets nearby the unit. 2. Place the bypass valve(s) in “bypass” position. See Figure 10. Single Valve Bypass PULL OUT for Service PUSH IN for Bypass 3. Fully open the main water supply valve. Observe steady flow from the opened faucets, with no air bubbles. 4. EXACTLY as follows, place bypass valve(s) in “service”. a.
Step 11. Connect Transformer NOTE: Check to be sure all leadwire connectors are secure on the back of the electronic board. CAUTION: Be sure all wiring is away from the valve gear and motor area, which rotates during regenerations. 1. Plug the transformer into a continuously “live”, grounded house electrical outlet, approved by local codes. THE UNIT WORKS ON 24V ONLY. DO NOT CONNECT WITHOUT THE TRANSFORMER. Step 12.
Programming the Faceplate Timer Figure 12 If you have questions about installation, programming, operating and routine maintenance... call 1-800-356-7851 When the transformer is plugged into the electrical outlet, a model code and a test number (example: s3.0), begins to flash in the faceplate display. Then, 12:00 AM and PRESENT TIME begins to flash. NOTE: If SR --or ----shows in the display, press the UP L or DOWN M button until LE31 shows.
Step 2. Set Water Hardness Number 1. Press the SELECT MENU (Select/Menu) button once to display a flashing 25 and HARDNESS. 2. Press the UP L or DOWN M buttons to set your water hardness number. NOTE: Be sure to enter the grains per gallon (gpg) hardness of your water supply on page 4, for future reference. 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.
Step 4. Set Salt Efficiency When this feature is ON, the unit will operate at salt efficiencies of 4000 grains of hardness per pound of salt or higher. (May recharge more often using smaller salt dosage and less water). 1. Press and hold the SELECT MENU (Select/Menu) button until the following screen is displayed. Once in this display, press the plays is shown. SELECT MENU (Select/Menu) button and one of the following two dis- 2. Press the UP L or DOWN M buttons to set On or Off.
Customizing Features/Options Recharge Now If you have guests, or other times when more water than usual is used, you could begin to run out of conditioned water. If the unit is not scheduled to regenerate for another day or two, you could get hard water until then. If this occurs, do the following to start an immediate regeneration. • Press and hold the RECHARGE (Recharge) button until RECHARGE NOW flashes in the display, and the softener enters the fill cycle of regeneration right away.
Customizing Features/Options Adjustable Backwash If your incoming water supply has higher sediments or iron, a longer Backwash and/or Fast Rinse time may help in keeping the unit cleaner. 1. Press and hold the SELECT MENU Once in this display, press the (Select/Menu) button until the following screen is displayed. SELECT MENU (Select/Menu) button until the following display is shown. 2. Press the UP L or DOWN M buttons to change the backwash time from 0 to 60 minutes. 3.
Routine Maintenance Refilling With Salt Remove the Salt Storage Tank Front Cover and check the salt storage level frequently. If the conditioner uses all the salt before you refill it, you will get hard water. Until you have established a refilling routine, check the salt every two or three weeks. ALWAYS add if less than 1/3 full. Be sure the Brinewell Cover is on. NOTE: In humid areas, it is best to keep the salt storage level lower, and to refill more often.
Cleaning the Nozzle and Venturi A clean nozzle and venturi (see Figure 14) is a must for the conditioner to work properly. This small unit 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 conditioner will not work, and you will get hard water. To get to the nozzle and venturi, slide Faceplate Cover forward. Be sure the unit is in soft water cycle (no water pressure at nozzle and venturi).
Protect the Water Softener from Freezing If the softener is installed where it could freeze (summer cabin, lake home, etc.), you must drain all water from it to stop possible freeze damage. To drain the softener: 1. Close the shut-off valve on the house main water pipe, near the water meter or pressure tank. 2. Open a faucet in the soft water pipes to vent pressure in the softener. 3. Refer to Figure 10 on page 16. Move the stem in a single bypass valve to bypass.
Troubleshooting Guide Tools Needed for Most Repairs: 5/16 Hex Driver, Phillips Screwdriver, Needle-nose Pliers PROBLEM CAUSE SOLUTION No Soft Water 1. No Salt in the storage tank No Soft Water Timer Display Blank 1. Transformer unplugged at wall outlet, or power cable a. Check for loss of power and correct. Reset timer disconnected from back of faceplate, and use the Recharge Now feature (page 20) Transformer defective Transformer 2. Fuse blown, circuit breaker popped, or circuit switched off.
Automatic Electronic Diagnostics The faceplate has a self-diagnostic function for the electrical system (except input power and/or water meter). The faceplate monitors electronic components and circuits for correct operation. If a malfunction occurs, an error code appears in the faceplate display. The troubleshooting chart on page 26 shows the error codes that could appear, and the possible defects for each code.
NOTE: Be sure water is in contact with the salt, and not separated by a salt bridge... see page 23. 5. While in this diagnostic screen, the following information is available and may be beneficial for various reasons. This information is retained by the computer from the first time electrical power is applied to the face plate. a. Press UP L to display the number of days this face plate has had electrical power applied. b.
3. Again, press the RECHARGE (Recharge) button to move the softener into backwash. Look for a fast flow of water from the drain hose. a. An obstructed flow indicates a plugged top distributor, backwash flow plug, or drain hose. 4. Press the RECHARGE (Recharge) button to move the softener into fast rinse. Again look for a fast drain flow. Allow the softener to rinse for a few minutes to flush out any brine that may remain in the resin tank from the brining cycle test. 5.
