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 sulfate- reducing 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. 14 Culligan Soft-Minder Twin® Softeners 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. 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, 0-120 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. Installation 15 Salt Supply, Usage & Service Salt is the mineral used to “recharge” your water conditioner. A brine solution is automatically made up in the bottom of the salt storage container, the Cullex® resin beads in the mineral tank are flushed with the brine solution as a step in the recharging process. Your Culligan Water Conditioner has been carefully designed to get the greatest amount of softening capacity from the salt it uses. Here is some pertinent information about salt usage, types and service. Salt Economizer This control is set at the time of installation, and determines salt usage according to the water hardness, number of persons in the household, and water usage. What Kind of Salt is Best All Culligan Water Conditioners are designed to use any water conditioner salt of good quality, including “rock”, “pellet”, “solar”, or “evaporated” types. All rock salt, regardless of source, contains insoluble material which collects at the bottom of the salt storage tank and requires periodic clean-out. If purified salt products are used, the salt storage compartment will require less frequent clean-out, but you must check more frequently for “bridging”. Regardless of what type of salt is used, we recommend Culligan Brand Salt as s...
