INSTALLATIONWE RECOMMEND THAT YOU READ THIS ENTIRE MANUAL BEFORE STARTING THEACTUAL INSTALLATION. WHILE WE STRONGLY RECOMMEND THAT A LICENSEDPLUMBER PERFORM ALL INSTALLATION WORK, A MECHANICALLY-INCLINEDHOMEOWNER WITH SUITABLE PLUMBING KNOWLEDGE CAN INSTALL THIS SYSTEM.IN ALL CASES, IT IS CRITICAL THAT THE INSTALLATION BE DONE IN ACCORDANCEWITH THESE INSTRUCTIONS AND ALL APPLICABLE PLUMBING AND ELECTRICALCODES. BE SURE TO OBTAIN ALL REQUIRED PERMITS. IF THESE INSTRUCTIONS ANDTHE APPLICABLE CODES ARE IN CONFLICT, THE RELEVANT PLUMBING/ELECTRICALCODE SHALL BE FOLLOWED. EQUIPMENT FAILURE, PERSONAL INJURY, OR PROPERTYDAMAGE CAN RESULT IF THIS EQUIPMENT IS NOT INSTALLED PROPERLY.Step 1. – Pre-Installation InspectionInspect all of the components that you received with your unit. You should have received thefollowing:1. Fleck 5810 SXT Control Valve2. Media Tank3. Upper Screen4. Bypass Assembly w/ Bypass Valve and 1” NPT Connector Yokes (2)5. Riser tube and Lower Distributor6. Bag or Box of Gravel7. Bag(s) or Box(es) of Cation Exchange Resin8. Drain Line Flow Control - DLFC (attached to #1)9. Brine Tank with Brine Well, Brine Valve assembly, Salt Grid, and Overflow Elbow10. Brine Tubing (10 feet)11. Funnel12. Small Parts Bag (contains food grade silicone O-ring lubricant, and parts for the brinetubing connections)7

Step 2. – Selecting an Installation LocationWhile exterior installation in warm climate areas is possible, we strongly recommend interiorinstallation only. The system cannot be allowed to freeze or severe system damage couldoccur. The system should not be exposed to rain and it should not be installed in directsunlight, as long-term exposure to UV light could damage components of the system.Furthermore, direct sunlight could raise the internal water temperature in the treatment tankand reduce backwash effectiveness.In most cases, the system should be located AFTER your water pump and pressure tank,AFTER the branch line to exterior irrigation, and BEFORE your hot water heater.8

IF YOU HAVE OTHER WATER TREATMENT EQUIPMENT, YOU SHOULD DISCUSS THEORDER OF YOUR TREATMENT EQUIPMENT WITH YOUR DEALER PRIOR TOINSTALLATION.Select a location for installation of your water filter that is within close proximity to the mainincoming water line of the home. The location should have a firm, level surface with enoughspace for the unit itself including the brine tank and sufficient space surrounding the unit tofacilitate maintenance. We recommend that the brine tank be located immediately besideyour treatment tank and control valve (it can be beside or in front). Frequent access to thebrine tank is necessary to add salt so it should be located in a readily accessible location.Although not ideal, if it is necessary, the brine tank can be located up to about 10 feet awayfrom the treatment tank and control valve (max. tubing length).WHILE WATER LEAKS ARE VERY RARE AND UNEXPECTED, YOUR WATER FILTERSYSTEM SHOULD BE LOCATED NEXT TO A FLOOR DRAIN OR PROTECTED BY A WATERLEAK DETECTION SYSTEM WITH AUTOMATIC SHUT-OFF VALVE TO PREVENT WATERDAMAGE TO YOUR PROPERTY IN THE UNLIKELY EVENT OF A WATER LEAK.RECOMMENDED WATER LEAK DETECTION SYSTEMS ARE AVAILABLE AT WWW.A-LEAKDETECTOR.COM.You will also require a suitable drain to discharge waste water from the backwash cycle. Adrain standpipe for a washing machine, floor drain, or sump pump are excellent drainoptions. We recommend that the drain line be connected to a minimum 1½" drainstandpipe or floor drain located ideally below the top of the head of your water filter. Ifpossible, the drain should be no farther than 20 feet from the system.NOTE: NEVER CONNECT THE DRAIN LINE DIRECTLY INTO A DRAIN PIPE. ALLOW AN AIRGAP BETWEEN THE DRAIN TUBING AND WASTE LINE TO PREVENT THE POSSIBILITYOF BACK-SIPHONING. WE DO NOT RECOMMEND USE OF A CHECK VALVE AS IT MAYBECOME CLOGGED WITH CONTAMINANTS EJECTED FROM THE SYSTEM DURINGBACKWASH.9

You will also need access to a standard, non-switched, grounded 120 volt (60 Hz) electricaloutlet. An extension cord may be used to reach a suitable electrical outlet. If this option isused, ensure that the extension cord is UL/CSA certified and of an appropriate wire gaugefor the application.Step 3. – Prepare Treatment TankTwo types of media are supplied with your system: gravel which forms the base layer(underbedding) in your treatment tank, and a cation exchange resin which removes certaincontaminants and softens the water.Place the tank in the location where it will sit when the installation is complete. Note that theblack base of your tank is not permanently attached to the rest of the tank. If your tankappears to be crooked, the base has likely been knocked out of alignment during shipping.This can be correct by picking the tank up and tapping it on a hard surface while holding itperpendicular to the floor. A few light taps will generally straighten it out.Temporarily remove the distributor and riser tube assembly from the treatment tank. Handtighten the Fleck 5810SXT control valve on the tank and mark where the front of the tank willbe. Turn the tank so that the front of the tank is where you want it when it is full – once it isfull of media and water, it becomes very heavy and difficult to move!Remove the control valve and re-insert the distributor and riser tube assembly into the tank.The distributor, which looks like a cone-shaped plastic screen, is pre-connected to the end ofthe long plastic riser tube which extends from the bottom of the tank to the top of the tankwhere the control valve is attached. At the bottom of the tank, there is a recess in the centerof the tank to accept the distributor to keep it properly aligned. The riser tube has been precut to the correct height for you. When the distributor is correctly positioned, the top of theriser tube will be approximately 1/8 to 1/4 of an inch below the top of the tank. If the tube isflush or protruding above the top of the tank, the distributor tube is not nested correctly in therecess at the bottom of the tank.Add enough water to the tank to cover the lower distributor with a minimum of 6 inches ofwater. This will prevent damage to the lower distributor as gravel is loaded. Place the funnelinto the tank so that the riser tube is in the middle. Place tape over the open end of the risertube. This will prevent gravel or media from accidentally going down the tube during thefollowing steps.10

For the following steps, we recommend that you wear a dust mask. Take the bag/box ofgravel and, using a small scoop, add the gravel to the tank through the funnel to completelycover the lower distributor. Use all of the gravel. Be sure to provide some downwardpressure on the riser tube while adding the gravel to ensure that the distributor does not shiftout of its recess or rise up. Ensure that you create an even layer of gravel across the bottomof the tank. A rigid piece of thin wall tubing (conduit, copper pipe, etc.), approximately 1”longer than the tank height works well as a leveling tool if you need it. Ensure that the risertube remains centered in the opening at the top of the tank.Once this is complete, add the cation exchange resin media in the same manner. Use all ofthe resin provided. Depending on the capacity of the system, there will only be enough resinto fill the tank to about 1/2 to 3/4 full. This is normal. The media tank should never be filledto the top of the tank as the remaining space, known as the “freeboard,” is necessary for themedia to have room to expand during the backwash cycle.Once you have finished adding the media to the tank, remove the tape from the distributortube. Be careful not to pull upwards on the riser tube while doing this as it is important thatthe distributor remain in its recess at the bottom of the tank.Fill the media tank with water up to within a couple of inches of the top of the tank.11

Attach the upper screen to the underside of the control valve.Be sure to twist clockwise and lock it into place.Apply a small amount of lubricant to the top inch of the outsideof the riser tube and to the tank o-ring seal.Note: Only use food-grade silicone lubricant. A small bag oflubricant is provided in the small parts bag. Do NOT usepetroleum jelly.The control valve can now be secured to the top of the tank.Before attaching the valve, check to make sure that there is nodebris such as gravel or resin in the tank threads. Screw thecontrol valve onto the tank – make sure that the riser tube insertsinto the center hole in the upper screen and the control valve asyou screw down the valve. The control valve should be hand-tightened (clockwise). DoNOT use the control valve's timer assembly for leverage and do not use tools. A firm graspwith both hands at the base of the valve will work. Do NOT use pipe cement (“pipe dope”) orTeflon tape on the threads.Step 4. – Turn off the Water & Electric Water HeatersFAILURE TO FOLLOW THIS PROCEDURE COULD RESULT IN SERIOUS, PERMANENTDAMAGE TO THE HEATING ELEMENTS IN YOUR WATER HEATER.If you have a conventional electric water heater or an on-demand (tankless) electric waterheater, we highly recommend that you turn off the power to the heater while installing anywater treatment equipment. Turn off power to your water heater now.Turn off the household main water shutoff valve. Open several plumbing fixtures inside thehome as well as the outside faucets to drain as much water out of the plumbing system aspossible.Following completion of the entire installation, restore the water flow by turning on thehousehold main water valve and allow all air to be purged from the plumbing system beforeturning the power back on to your water heater.12

Step 5. – Prepare and Install Inlet and Outlet Plumbing ConnectionsTEFLON TAPE IS THE ONLY SEALANT TO BE USED ON THE 1” NPT CONNECTORYOKES AND DRAIN FITTINGS.IF YOU WISH TO USE COPPER PIPING FOR YOUR INSTALLATION AND WILL BESOLDERING THE JOINTS, DO NOT APPLY HEAT NEAR YOUR CONTROL VALVE, BYPASSASSEMBLY, 1” NPT CONNECTOR YOKES, OR THE DRAIN FITTINGS; OTHERWISESERIOUS DAMAGE TO THESE PARTS COULD OCCUR. ALWAYS SOLDER JOINTS WITHTHESE COMPONENTS DETACHED. IF YOU ARE USING COPPER ADAPTERS TOCONNECT TO THE 1” NPT CONNECTOR YOKES, IT IS RECOMMENDED THAT YOUSOLDER A 6" PIECE OF COPPER PIPE INTO EACH OF THE CONNECTION ADAPTERSAWAY FROM THE VALVE, THEN LET THEM COOL OFF BEFORE THREADING THEM ONTOTHE 1” NPT CONNECTORS.Key Control Valve Components:1. Control Valve Body2. Bypass Valve3. 1” NPT (Male) Connector Yokes4. Drain Line Flow Control (DLFC)5. Valve Cover6. DLFC Retention ClipThe system’s control valve is connected toyour incoming and outgoing water lines byway of a bypass assembly with 1”NPT threadedfittings. This assembly is composed of thebypass valve and two 1”NPT connector yokes.Locate the inlet and outlet ports on the back of the control valve. Note that the inlet andoutlet are marked with arrows indicating the correct direction of water flow. When you arelooking at the back of the control valve, the inlet is on the left and the outlet is on the right.Check the corresponding markings on the bypass to ensure the correct direction of water13

flow and attach the bypass valve to the control valve. The in and out arrows on the bypassshould be pointing the same direction as the in and out arrows on the outside of the controlvalve.BE VERY CAREFUL TO MAKE SURE YOU PLUMB THE SYSTEM IN THE RIGHT DIRECTION.The bypass assembly is secured to the control valve using threaded fittings. Thread sealanttape should not be used on these threads. The seal is made by way of o-rings. To attachthe bypass to the control valve, simply thread the 2 nuts on the bypass onto the valve untilthe nuts bottom out on the valve body. Do not overtighten - it is normal for some “play” toexist when the bypass assembly is properly seated. This allows for minor misalignment ofthe piping connections and relieves stress on the valve. The 1” NPT connector yokes areconnected to the bypass in the same manner (they are normally shipped to you preconnected to the bypass, but you can separate them to make the plumbing to your mainwater lines easier if you want).You will need to purchase the appropriate NPT threaded fittings to connect the connectoryokes to the material and size of your main inlet and outl
