INSTALLATIONWater PressureA minimum of 20 psi (1.4 bar) of water pressure is required forthe regeneration valve to operate effectively.Electrical FacilitiesAn uninterrupted alternating current (120 VAC) supply isrequired. The control uses a transformer to supply 12 VDC.Please make sure your voltage supply is compatible with yourunit before installation.Existing PlumbingCondition of existing plumbing should be free from lime andiron buildup. Piping that is built up heavily with lime and/or ironshould be replaced. If piping is clogged with iron, a separateiron filter unit should be installed ahead of the water softener.Location of Softener and DrainYou must have an air gap on the drain line to prevent back flowof drain water into the system. A 2x the drain line pipe diameterair gap is required with a minimum 1" air gap.Air GapDrainFigure 1 Air Gap6. Soldering of joints near the drain port must be done prior toconnecting the Drain Line Flow Control fitting (DLFC). Leaveat least 6" (15 cm) between the DLFC and solder jointswhen soldering pipes that are connected on the DLFC.Failure to do this could cause interior damage to the DLFC.7. PTFE plumbing tape is the only sealant to be used on thedrain fitting.8. Make sure that the floor is clean beneath the salt storagetank and that the tank is level.9. Place approximately 1" (25 mm) of water above the gridplate. If a grid is not utilized, fill to the top of the air check(Figure 1) in the salt tank. Do not add salt to the brine tankat this time.CAUTION If grid plate is used, cut air check height even withgrid plate. This is critical on 6", 7", 8" and 9" tanks.The brine refill water must come above the gridplate and make contact with the salt.10. On units with a bypass, place in bypass position. Turn onthe main water supply. Open a cold soft water tap nearbyand let run a few minutes or until the plumbing is free fromforeign material (usually solder) that may have resultedfrom the installation. Once clean, close the water tap.11. Slowly place the bypass in service position and let waterflow into the mineral tank. When water flow stops, slowlyopen a cold water tap nearby and let water run until the airis purged from the plumbing lines.12. Plug the transformer into an electrical outlet.NOTE: All electrical connections must be connected accordingto local codes. Be certain the outlet is uninterrupted.Installation LocationsFOR DRY LOCATIONS ONLY.Bypass ValvesAlways provide for the installation of a bypass valve if unit is notequipped with one.CAUTION Water pressure is not to exceed 125 psi (8.6 bar),water temperature is not to exceed 110 F (43 C),and the unit cannot be subjected to freezingconditions.WARNING: The system must be depressurized beforeremoving any connections for servicing.Installation Instructions1. Place the softener tank where you want to install the unit.Make sure the unit is level and on a firm base.2. During cold weather, the installer should warm the valve toroom temperature before operating.3. All plumbing should be done in accordance with localplumbing codes. The pipe size for a residential drain lineshould be a minimum of 1/2" (13 mm). Backwash flow ratesin excess of 7 gpm (26.5 Lpm) or drain line length in excessof 20' (6 m) require 3/4" (19 mm) drain line. Commercialdrain lines should be the same size as the drain line flowcontrol.NOTE: The tank should have the distributor tube installed andhave the proper amount of regenerant in place.4. Refer to the spec sheet for cutting height of the distributortube.5. Lubricate the distributor O-ring seal and tank O-ringseal. Place the main control valve on tank. Note: Only usesilicone lubricant.4 FLECK 5810 & 5812 SXT Upflow/Downflow60002 Rev EFigure 2 Residential Air Check ValveElectrical ConnectionThe controller operates on 12-volt DC power supply. Do notoperate the controller with a power supply other than the onesupplied by the manufacturer for this model. For installationassistance, see Transformer Port Location on page 31.NOTE: The power source should be constant. Be certainthe power adapter is not on a switched outlet. Powerinterruptions longer than 8 hours may cause the controllerto lose the time setting. When power is restored, the timesetting must then be re-entered.

START-UP INSTRUCTIONS/FLUSHING & CONDITIONINGThe water softener should be installed with the inlet,outlet, and drain connections made in accordance with themanufacturer’s recommendations, and to meet applicableplumbing codes.1. Program the valve control according to instructions shownin this manual.2. Start an immediate regeneration by holding the Extra Cyclebutton for five seconds. Position the valve to backwash.Ensure the drain line flow remains steady for 10 minutes oruntil the water runs clear.3. Position the valve to the brine draw / slow rinse position.Ensure the unit is drawing water from the brine tank (thisstep may need to be repeated).4. Position the valve to the rapid rinse position. Check thedrain line flow, and run for five minutes or until the waterruns clear.5. Position the valve to the start of the brine tank fill cycle.Ensure water goes into the brine tank at the desired rate.The brine valve drive cam will hold the valve in this positionto fill the brine tank for the first regeneration.6. Replace control cover.7. Put salt in the brine tank.NOTE: Do not use granulated or rock salt.CONTROL FEATURES The Parameter Display displays the current cycle step(BW, BF, RR etc) during regeneration, and the datadisplay counts down the time remaining for that cyclestep. While the valve is transferring to a new cycle step,the display will flash. The parameter display will identifythe destination cycle step (BW, BF, RR, etc.) and the datadisplay will read "------". Once the valve reaches the cyclestep, the display will stop flashing and the data displaywill change to the time remaining. During regeneration,the user can force the control to advance to the next cyclestep immediately by pressing the Extra Cycle button.Setting the Time of Day1. Press and hold either the Up or Down buttons until theprogramming icon replaces the service icon and theparameter 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 buttonto resume normal operation. The unit will also returnto normal operation after five seconds if no buttons arepressed.Figure 4Queueing a Regeneration1. Press the Extra Cycle button. The service icon will flash toindicate that a regeneration is queued.2. To cancel a queued regeneration, press the Extra Cyclebutton.Regenerating ImmediatelyPress and hold the Extra Cycle button for five seconds.Figure 3Features of the SXT: Power backup that continues to keep time and thepassage of days for a minimum of 8 hours in the event ofpower failure. During a power outage, the control goesinto a power-saving mode. It does not monitor waterusage during a power failure, but it does store the volumeremaining at the time of power failure. Settings for both valve (basic system) and control type(method used to trigger a regeneration). Day-of-the-Week controls. While in service, the display alternates between time ofday, volume remaining or days to regeneration. The Flow Indicator flashes when outlet flow is detected. The Service Icon flashes if a regeneration cycle has beenqueued. A Regeneration can be triggered immediately by pressingthe Extra Cycle button for five seconds.FLECK 5810 & 5812 SXT Upflow/Downflow 5
