5 Introduction It s All So Easy, So Economical, So Efficient, So Enjoyable! Kind To Skin And Complexion Soft water will help prevent red, itchy or dry skin because there are no hardness impurities to cause soreness, no soap curd to coat the skin. Shaving is easier, smoother - either with blade or electric shaver. Bathing And Showering You ll use far less soap with conditioned water. Use your soap very sparingly - not as you did before soft water. Just a quick rinse removes all lather, leaving your skin pleasantly smooth and silky - because now it s free of sticky soap curd and film. Saves Washing Costs. Helps Control Environmental Pollution Soft water washes whiter and cleaner with less soap or detergent. Because the hardness impurities are removed, your soap can concentrate solely on washing. People usually find that they can reduce the amount of soap they use substantially. If you normally used a cup per wash load with hard water, try using only 1/3 cup depending on the size of your wash load and the degree of soil. Different amounts are required, but you can use less with softened water. An added bonus is the fact that your washable fabrics will last longer. Super Hair Conditioning Soft water is great for scalp and hair care. No insoluble deposits are formed. Hair is shinier, softer, more manageable. Reduce the amount of shampoo you have normally used. Dishes Are A Delight Washed by hand or in a dishwasher, glassware, dishes and silver wash cleaner, easier. Follow your dishwasher manufacturer s instructions. Soft water promotes sanitation because no greasy hard water film can form to collect or harbor bacteria. Easier Housekeeping, Gleaming Fixtures You ll be amazed at the marvelous difference. Just a swish of the cloth, and the bathtub or shower and fixtures are clean and sparkling. Imagine, no scouring! No hard water scum to cause rings, streaks, spots and stains. To keep their gleaming luster, simply wipe fixtures with a towel after use. Formica, tile, walls, floors, woodwork surfaces clean easier, stay clean longer. You ll save on cleaning aids and save on time. Saves Water-heating Energy, Helps Water-using Appliances Soft water reduces the formation of rock-like hard water scale which encrusts water heaters, hot water pipes, shower heads, and water-using appliances. This scale can cause premature maintenance and failure. Elimination of hard water also provides substantial energy savings because scale acts as an insulator, wasting electricity or gas used to heat water. Savings Galore A water conditioner is frequently referred to as the appliance that pays for itself. You ll find that your savings on soaps, detergents, cleaning aids, and personal care products will help your family s household budget. And if you place a price on your time, you ll be most happy with the time saved by your new family servant. Water For Lawns And Household Plants If possible, lawn sprinkling faucets should be supplied with hard water primarily because it is uneconomical to soften so much water. Household plants are much more sensitive than lawns with respect to the kind of water which is best. First, because they receive no rainfall and, second, there is little or no drainage of the soil. Preferably they should be watered with rain water or water which is low in mineral content such as distilled or demineralized water. Softened water is not recommended for house plants because a build-up of sodium in the soil may interfere with efficient absorption of water by the plant root system. Additional information may be obtained from your independently operated Culligan dealer. Introduction 5

6 How Your Water Conditioner Works Why Water Gets Hard And How It s Softened All of the fresh water in the world originally falls as rain, snow, or sleet. Surface water is drawn upward by the sun, forming clouds. Then, nearly pure and soft as it starts to fall, it begins to collect impurities as it passes through smog and dust-laden atmosphere. And as it seeps through soil and rocks it gathers hardness, rust, acid, unpleasant tastes and odors. Water hardness is caused primarily by limestone dissolved from the earth by rainwater. Because of this, in earlier times people who wanted soft water collected rainwater from roofs in rain barrels and cisterns before it picked up hardness from the earth. Some localities have corrosive water. A softener cannot correct this problem and so its printed warranty disclaims liability for corrosion of plumbing lines, fixtures or appliances. If you suspect corrosion, your Culligan Man has equipment to control the problem. Iron is a common water problem. The chemical/physical nature of iron found in natural water supplies is exhibited in four general types. 1. Dissolved Iron - Also called ferrous or clear water iron. This type of iron can be removed from the water by the same ion exchange principle that removes the hardness elements, calcium and magnesium. Dissolved iron is soluble in water and is detected by taking a sample of the water to be treated in a clear glass. The water in the glass is initially clear, but on standing exposed to the air, it may gradually turn cloudy or colored as it oxidizes. 2. Particulate Iron - Also called ferric or colloidal iron. This type of iron is an undissolved particle of iron. A softener will remove larger particles, but they may not be washed out in regeneration effectively and will eventually foul the ion exchange resin. A filtering treatment will be required to remove this type of iron. 3. Organic Bound Iron - This type of iron is strongly attached to an organic compound in the water. The ion exchange process alone cannot break this attachment and the softener will not remove this type of iron. 4. Bacterial Iron - This type of iron is protected inside a bacteria cell. Like the organic bound iron, it is not removed by a water softener. When using a softener to remove both hardness and dissolved iron it is important that it regenerates more frequently than ordinarily would be calculated for hardness removal alone. Although many factors and formulas have been used to determine this frequency, it is recommended that the softener be regenerated when it has reached 50-75% of the calculated hardness alone capacity. This will minimize the potential for bed fouling (Iron removal claims have not been verified by the Water Quality Association). If you are operating a water softener on clear water iron, regular resin bed cleaning is needed to keep the be from coating with iron. Even when operating a softener on water with less than the maximum of dissolved iron, regular cleanings should be performed. Clean every six months or more often if iron appears in your conditioned water supply. Use resin bed cleaning compounds carefully following the directions on the container. Caution! Do not use where the water is microbiologically unsafe or with water of unknown quality without adequate disinfection before or after the unit. Hardness sample kits are available through your local Culligan dealer. 6 Culligan Soft-Minder Twin Softeners

7 The Culligan Process Your Culligan water conditioner consists of three basic components, (A) the Control Valve, (B) the Mineral Tank, and (C) the Brine System. A. The exclusive Culligan control valve automatically performs a variety of tasks that are necessary for the proper operation of your water conditioner. These tasks, commonly referred to as cycles or operating positions, are: Service, Regeneration, and Brine Refill. 1. Service: While the control valve is in the Service cycle, hard water is directed down through the column of Cullex resin where hardness minerals are removed from the water. The softened water is then directed into your household plumbing lines. The ability of the Cullex resin to remove hardness minerals needs to be periodically replenished; this is referred to as Regeneration: While the control valve is in the Regeneration cycle, water is first directed up through the column of Cullex resin to flush accumulated sediment out of the resin and down the drain. Then, the regenerant brine solution is slowly drawn from the bottom of the salt storage tank of the Brine System and is directed down through the column of Cullex resin, restoring the ability of the resin to remove hardness minerals from your water supply. Once completed, the regeneration cycle is followed by Brine Refill: While the control valve is in the Brine Refill cycle, a predetermined amount of water is directed to the salt storage tank of the Brine System so that additional salt can be dissolved to provide the brine solution that will be needed for the next regeneration cycle. B. The exclusive Quadra-Hull Mineral Tank contains the Cullex resin column, Cullsan underbedding, and an outlet manifold. The number of gallons of hard water that can be softened by the Cullex resin column before it needs regeneration is called the capacity of the resin column, and depends upon the amount of hardness minerals in each gallon of water (expressed as grains per gallon) and upon the amount of regenerant brine solution (expressed as pounds of salt) passed through the resin column during regeneration. Your Culligan service person, taking into account the hardness of your water and the amount of softened water your household may reasonably expect to use each day, has carefully established how often the softener will regenerate and how much salt will be used for each regeneration. This will ensure that all of your soft water needs will be fulfilled without using an excessive amount of salt. C. The Brine System consists of a salt storage container and hydraulic Dubl-Safe valve. The salt storage container holds the salt that is used to make the regenerant brine solution. The hydraulic Dubl-Safe valve limits the amount of water that is returned to the salt storage tank during the brine refill cycle. Since a predetermined amount of salt is dissolved with each brine refill cycle, the salt must be periodically replenished in order to maintain efficient operation. Your Culligan service person will be able to tell you about how often salt must be added to the salt storage container. Introduction 7

8 Preparation Component Description The water conditioner is shipped from the factory in a minimum of four cartons. Remove all components from their cartons and inspect them before starting installation. Control Valve Assembly - Includes the Soft-Minder Twin Control. Small parts packages will contain additional installation hardware, and the conditioner Owner s Guide.

9 Application Water quality - Verify that raw water hardness and iron are within limits. Note the hardness for setting the salt dosage and recharge frequency. Pressure - If pressure exceeds 125 psi (860 kpa), install a pressure reducing valve (see materials checklist). On private water systems, make sure the minimum pressure (the pressure at which the pump starts) is greater than 20 psi (140 kpa). Adjust the pressure switch if necessary. Caution! The use of a pressure reducing valve may limit the flow of water in the household. Temperature - Do not install the unit where it might freeze, or next to a water heater or furnace or in direct sunlight. Outdoor installation is not recommended and voids the warranty. If installing in an outside location, you must take the steps necessary to assure the softener, installation plumbing, wiring, etc. are as well protected from the elements (sunlight, rain, wind, heat, cold), contamination, vandalism, etc. as when installed indoors. Location Space requirements - Allow 6-12 inches (15-30 cm) behind the unit for plumbing and drain lines and 4 feet (1.3 meters) above for service access and filling the salt container (See figure 1). Floor surface - Choose an area with solid, level floor free of bumps or irregularities. Bumps, cracks, stones and other irregularities can cause the salt storage tank bottom to crack when filled with salt and water. Drain facilities - Choose a nearby drain that can handle the rated drain flow (floor drain, sink or stand pipe). Refer to the Drain Line Chart, Table 1 (page 11), for maximum drain line length. Note: Most codes require an anti-siphon device or air gap. Observe all local plumbing codes and drain restrictions. The system and installation must comply with all state and local laws and regulations. Waste connections or drain outlets shall be designed and constructed to provide for connection to the sanitary waste system through an air gap of 2 pipe diameters or 25 mm (1 in.), whichever is larger. Electrical facilities - A 10-foot cord and wall mount plug-in transformer are provided. The customer should provide a receptacle, preferably one not controlled by a switch that can be turned off accidentally. Observe local electrical codes. Note: The softener works on 24 volt - 60 Hz power only. Be sure to use the included transformer. Be sure the electrical outlet and transformer are in an inside location to protect from moisture. Properly ground to conform with all governing codes and ordinances. Preparation 9

TREATED WATER OUT TO HOSE BIBS DRAIN LINE HARD WATER IN AIR GAP HEATER BRINE TANK WATER METER OR PUMP Figure 1 SOFT-MINDER TWIN Placement Set the media tanks on a solid, level surface that provides easy access to a water supply, drain system and electricity. Place the brine system on a flat, smooth, solid surface close to the media tank. Plumbing should comply with the applicable state and local plumbing codes. Connect the couplings and yoke assembly to the control valve and tank adapter. Lubricate the O-ring with silicone lubricant. Lubricate the distributor and tank O-ring seal with silicone lubricant. The joints near the drain must be soldered prior to connecting the drain line flow control fitting (DLFC). Leave at least 6 between the DLFC and the joints when soldering. Failure to do this could cause damage to the drain module. Teflon tape is the only sealant to be used on the drain fittings. Control Valve A 0.5 gpm BLFC is installed in the control valve. A 0.25 gpm BLFC is included in the control parts pack that needs to be used on 9 tank when salt dosage is less than 5 lbs. Remove the BLFC from the brine valve. Install the BLFC by removing the brine fitting, remove the retainer, remove and replace with the proper size. A white #1 eductor throat and nozzle is packaged with the control valve for use on the 9-inch tanks. See table 2 (page 19) for eductor throat and nozzle selections. When changing the eductor nozzle and throat, remove the eductor assembly mounting screws. Carefully remove the eductor assembly from the control. Unscrew the eductor nozzle and throat and replace with the correct size eductor. Reassemble onto the control valve. Included in the parts pack are drain line flow controls with different gpm capacities. Tank size will determine which size flow control to install. Use the 2.00 gpm for the 9-inch tank and 10-inch tank. See table 2 (page 19) for DLFC selections Install the DLFC by removing the drain line elbow adapter. Unscrew Figure 2 10 Culligan Soft-Minder Twin Softeners

11 the retainer, remove and replace with the proper size. Install the retainer and the drain line elbow adapter. The numbered side of the DLFC must face down. Start-Up Place approximately 1 of water above the grid plate (if used) in your salt tank. Salt may be placed in the unit at this time. Place softener in a bypass position. Turn on the main water supply and check for any leaks. Open a cold water faucet near the softener and run a few minutes until the system is free of any foreign material (usually solder) that may have resulted from the installation. Plug unit into electrical outlet. Do not insert meter cable into the meter at this time. Electrical connections must be connected according to codes. Advance the softener control to the backwash position. Slowly shift the bypass into the service position so that the water flows into the mineral tanks. When water appears at the drain, shift the bypass valve to fully open. Continue to backwash until the water at drain is clear. Start REGEN to fill second tank. Backwash until the water at drain is clear.

12 Control Start-up Procedures Parameter Display Data Display PM Indicator Error/ Information Icon Service Icon Flow Indicator x1000 Indicator Programming Icon Extra Cycle Button Up Button Down Button Features of the Timer: Power backup that continues to keep time and the passage of days for a minimum of 48 hours in the event of power failure. During a power outage, the control goes into a power-saving mode. It does not monitor water usage during a power failure, but it does store the volume remaining at the time of power failure. Day-of-the-Week controls. While in service, the display alternates between time of day, volume remaining or days to regeneration, and tank in service (twin tank systems only). The Flow Indicator flashes when outlet flow is detected. The Service Icon flashes if a regeneration cycle has been queued. A Regeneration can be triggered immediately by pressing the Extra Cycle button for five seconds. The Parameter Display displays the current Cycle Step (BW, BF, RR, etc) during regeneration, and the data display counts down the time remaining for that cycle step. While the valve is transferring to a new cycle step, the display will flash. The parameter display will identify the destination cycle step (BW, BF, RR, etc) and the data display will read Once the valve reaches the cycle step, the display will stop flashing and the data display will change to the time remaining. During regeneration, the user can force the control to advance to the next cycle step immediately by pressing the extra cycle button. Setting the Time of Day 1. Press and hold either the Up or Down buttons until the programming icon replaces the service icon and the parameter display reads TD. 2. Adjust the displayed time with the Up and Down buttons. 3. When the desired time is set, press the Extra Cycle button to resume normal operation. The unit will also return to normal operation after 5 seconds if no buttons are pressed. 12 Culligan Soft-Minder Twin Softeners

13 Queueing a Regeneration 1. Press the Extra Cycle button. The service icon will flash to indicate that a regeneration is queued. 2. To cancel a queued regeneration, press the Extra Cycle button. Regenerating Immediately Press and hold the Extra Cycle button for five seconds. Meter Immediate Control A meter immediate control measures water usage and regenerates the system as soon as the calculated system capacity is depleted. The control calculates the system capacity by dividing the unit capacity (typically expressed in grains/unit volume) by the feedwater hardness and subtracting the reserve. Meter Immediate systems generally do not use a reserve volume. However, in twin tank systems with soft-water regeneration, the reserve capacity should be set to the volume of water used during regeneration to prevent hard water break-through. A Meter Immediate control will also start a regeneration cycle at the programmed regeneration time if a number of days equal to the regeneration day override pass before water usage depletes the calculated system capacity. Time Clock Delayed Control A Time Clock Delayed Control regenerates the system on a timed interval. The control will initiate a regeneration cycle at the programmed regeneration time when the number of days since the last regeneration equals the regeneration day override value. Day of the Week Control This control regenerates the system on a weekly schedule. The schedule is defined in Master Programming by setting each day to either off or on. The control will initiates a regeneration cycle on days that have been set to on at the specified regeneration time. Control Operation During Regeneration During regeneration, the control displays a special regeneration display. In this display, the control shows the current regeneration step number the valve is advancing to, or has reached, and the time remaining in that step. The step number that displays flashes until the valve completes driving to this regeneration step position. Once all regeneration steps are complete the valve returns to service and resumes normal operation. Pressing the Extra Cycle button during a regeneration cycle immediately advances the valve to the next cycle step position and resumes normal step timing. Control Operation During Programming The control only enters the Program Mode with the valve in service. While in the Program Mode, the control continues to operate normally monitoring water usage and keeping all displays up to date. Control programming is stored in memory permanently, eliminating the need for battery backup power. Manually Initiating a Regeneration 1. When timer is in service, press the Extra Cycle button for 5 seconds on the main screen. 2. The timer advances to Regeneration Cycle Step #1 (backwash), and begins programmed time count down. 3. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #2 (brine draw & slow rinse). 4. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #3 (rapid rinse). 5. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #4 (brine refill). 6. Press the Extra Cycle button once more to advance the valve back to in service. NOTE: If the unit is a filter or upflow, the cycle step order may change. NOTE: A queued regeneration can be initiated by pressing the Extra Cycle button. To clear a queued regeneration, press the Extra Cycle button again to cancel. If regeneration occurs for any reason prior to the delayed regeneration time, the manual regeneration request shall be cleared. Control Start-up Procedures 13

14 Control Operation During A Power Failure The timer includes integral power backup. In the event of power failure, the control shifts into a power-saving mode. The control stops monitoring water usage, and the display and motor shut down, but it continues to keep track of the time and day for a minimum of 48 hours. The system configuration settings are stored in a non-volatile memory and are stored indefinitely with or without line power. The Time of Day flashes when there has been a power failure. Press any button to stop the Time of Day from flashing. If power fails while the unit is in regeneration, the control will save the current valve position before it shuts down. When power is restored, the control will resume the regeneration cycle from the point where power failed. Note that if power fails during a regeneration cycle, the valve will remain in it s current position until power is restored. The valve system should include all required safety components to prevent overflows resulting from a power failure during regeneration. The control will not start a new regeneration cycle without line power. If the valve misses a scheduled regeneration due to a power failure, it will queue a regeneration. Once power is restored, the control will initiate a regeneration cycle the next time that the Time of Day equals the programmed regeneration time. Typically, this means that the valve will regenerate one day after it was originally scheduled. If the treated water output is important and power interruptions are expected, the system should be setup with a sufficient reserve capacity to compensate for regeneration delays. When the Master Programming Mode is entered, all available option setting displays may be viewed and set as needed. Depending on current option settings, some parameters cannot be viewed or set. Setting the Time of Day 1. Press and hold either the Up or Down buttons until the programming icon replaces the service icon and the parameter display reads TD. 2. Adjust the displayed time with the Up and Down buttons. When the desired time is set, press the Extra Cycle button to resume normal operation. The unit will also return to normal operation after 5 seconds if no buttons are pressed. Entering Master Programming Mode Set the Time Of Day display to 12:01 P.M. Press the Extra Cycle button (to exit Setting Time of Day mode). Then press and hold the Up and Down buttons together until the programming icon replaces the service icon and the Display Format screen appears. Exiting Master Programming Mode Press the Extra Cycle button to accept the displayed settings and cycle to the next parameter. Press the Extra Cycle button at the last parameter to save all settings and return to normal operation. The control will automatically disregard any programming changes and return to normal operation if it is left in Master Programming mode for 5 minutes without any keypad input. Resets: Soft Reset: Press and hold the Extra Cycle and Down buttons for 25 seconds while in normal Service mode. This resets all parameters to the system default values, except the volume remaining in meter immediate or meter delayed systems and days since regeneration in the time clock system. Master Reset: Hold the Extra Cycle button while powering up the unit. This resets all of the parameters in the unit. Check and verify the choices selected in Master Programming Mode. 14 Culligan Soft-Minder Twin Softeners

24 Sanitizing Procedure A water softener in daily use on a potable water supply generally requires no special attention other than keeping the salt tank filled. Occasionally, however, a unit may require sanitization under one of the following conditions: At start-up time. After standing idle for a week or more. On private supplies, the appearance of off-tastes and odors, particularly if musty or rotten egg (caused by harmless sulfatereducing bacteria). Note: If the water supply contains iron, regenerate the softener before sanitizing to remove iron from the resin. Caution! Hazard from toxic fumes! Chlorine bleach and common iron control chemicals may generate toxic fumes when mixed. If the unit uses Culligan Sofner-Gard or other compounds containing sodium hydrosulfite, sodium bisulfite, or any other reducing agent, disconnect the device feeding the chemical(s) and manually regenerate the unit before sanitizing. Do not use this procedure if the softener salt contains iron control additives. 1. Remove the brine tank cover. 2. Pour directly into the brine chamber 1/3-1/2 cup of common household bleach (5.25% sodium hypochlorite) for each cubic foot of resin in the tank. Do not use lemon scented bleaches, or similar bleaches that contain perfumes. 3. Manually start recharge. Allow the unit to complete the recharge cycle automatically. If tastes and odors return frequently, even after sanitization, a continuous chlorination system may be needed. Send a water sample to a qualified laboratory for bacterial analysis. 24 Culligan Soft-Minder Twin Softeners

25 Analyzing the System Analyzing the problem involves three basic steps: 1. Check the system in all cycle positions. 2. Compare the data to normal operating data. 3. Determine which component may cause the problem (troubleshooting). 4. If steps 1-3 did not reveal the problem, initiate a regeneration cycle and manually cycle the valve to brine draw (#2 position). Allow the unit to complete the brine draw cycle and observe how the system reacts. Although it may be possible to solve a specific problem simply by changing a component, analyzing the entire system can reveal additional problems which would otherwise require extra service calls. Parts changing is not the same as service. Check the System The following tools are needed to collect data: 1. Hardness, iron and chlorine test kits 2. Thermometer 3. Pressure gauge, psi 4. 5-Gallon bucket and watch 5. Calculator The customer can provide most data. By collecting data prior to a service call, a first guess about the cause of the problem can be made and the need for any special parts can be determined. If the problem is as simple as lack of salt in the brine tank, a service call may not be needed at all. At the end of Appendix A is a recommended system data sheet that will assist the troubleshoot process. Before Leaving the Installation Site 1. Sanitizing the softener. See sanitizing procedure on previous page. 2. Ensure that the brine tank has water to the level of the float. Add water to the tank with a hose or put the unit into a full recharge so that the brine refill cycle will fill the tank with the proper amount of water. 3. The water heater will hold hard water for several days. Advise the customer that the existing water volume in the tank will need to be used before the hot water is soft. If soft hot water is required immediately, refer to the water heater owner s manual for the proper method of draining the water heater. 4. Explain the operation of the softener to the customer. Make sure the customer knows that there will be new sounds associated with the recharging of the unit. Advise the customer to periodically check and replenish the salt supply. 5. Clean up the unit and installation site, removing any soldering, or pipe threading, residues from the equipment and surrounding area with a damp towel. Diagnostics 25
