INSTALLATIONWater PressureA minimum of 20 pounds (1.4 bar) of water pressure is requiredfor regeneration valve to operate effectively.Electrical FacilitiesAn uninterrupted alternating current (A/C) supply is required.Note: Other voltages are available. Please make sure yourvoltage supply is compatible with your unit before installation.11. Slowly place the by-pass in service position and let waterflow into the mineral tank. When water flow stops, slowlyopen a cold water tap nearby and let run until the air ispurged from the unit.12. Plug unit into an electrical outlet. Note: All electricalconnections must be connected according to local codes.Be certain the outlet is uninterrupted.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 DrainThe softener should be located close to a drain to prevent airbreaks and back flow.By-Pass ValvesAlways provide for the installation of a by-pass valve if unit isnot equipped 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.Installation Instructions1. Place the softener tank where you want to install the unitmaking 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 residential drain lineshould be a minimum of 1/2" (13 mm). Backwash flow ratesin excess of 7 gpm (26.5 Lpm) or length in excess of 20’(6 m) require 3/4" (19 mm) drain line. Commercial drainlines should be the same size as the drain line flow control.4. Refer to the dimensional drawing for cutting height of thedistributor tube. If there is no dimensional drawing, cut thedistributor tube flush with the top of the tank.5. Lubricate the distributor O-ring seal and tank O-ring seal.Place the main control valve on tank. Note: Only usesilicone lubricant.6. Solder joints near the drain must be done prior toconnecting the Drain Line Flow Control fitting (DLFC).Leave at least 6" (15 cm) between the DLFC and solderjoints when soldering pipes that are connected on theDLFC. Failure to do this could cause interior damage to theDLFC.7. Teflon tape is the only sealant to be used on the drainfitting. The drain from twin tank units may be run through acommon line.8. Make sure that the floor is clean beneath the salt storagetank and that it 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.10. On units with a by-pass, place in by-pass position. Turn onthe main water supply. Open a cold soft water tap nearbyand let run a few minutes or until the system is free fromforeign material (usually solder) that may have resultedfrom the installation. Once clean, close the water tap.2 JE11 Fleck 5600SXT Downflow60002 Rev EFigure 1 Residential Air Check ValveSTART-UP INSTRUCTIONSThe water softener should be installed with the inlet, outlet, anddrain connections made in accordance with the manufacturer’srecommendations, and to meet applicable plumbing codes.1. Turn the manual regeneraton knob slowly in a clockwisedirection until the program micro switch lifts on top of thefirst set of pins. Allow the drive motor to move the piston tothe first regeneration step and stop. Each time the programswitch position changes, the valve will advance to the nextregeneration step. Always allow the motor to stop beforemoving to the next set of pins or spaces.NOTE: For electronic valves, please refer to the manualregeneration part of the timer operation section.If the valve came with a separate electronictimer service manual, refer to the timeroperation section of the electronic timer servicemanual.2. Position the valve to backwash. Ensure the drain line flowremains steady for 10 minutes or until the water runs clear(see above).3. Position the valve to the brine / slow rinse position. Ensurethe unit is drawing water from the brine tank (this step mayneed to be repeated).4. Position the valve to the rapid rinse position. Check thedrain line flow, and run for 5 minutes or until the water runsclear.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 box cover.7. Put salt in the brine tank.NOTE: Do not use granulated or rock salt.

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, and tankin service (twin tank systems only). 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. 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 DO.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 return tonormal operation after 5 seconds if no buttons are pressed.Queueing a Regeneration1. Press the Extra Cycle button. The service icon will flash toindicate that a regeneration is queued.2.

TIMER OPERATIONMeter Immediate ControlA meter immediate control measures water usage andregenerates the system as soon as the calculated systemcapacity is depleted. The control calculates the systemcapacity by dividing the unit capacity (typically expressed ingrains/unit volume) by the feedwater hardness and subtractingthe reserve. Meter Immediate systems generally do not usea reserve volume. However, in twin tank systems with softwater regeneration, the reserve capacity should be set to thevolume of water used during regeneration to prevent hardwater break-through. A Meter Immediate control will also starta regeneration cycle at the programmed regeneration time ifa number of days equal to the regeneration day override passbefore water usage depletes the calculated system capacity.Meter Delayed ControlA Meter Delayed Control measures water usage andregenerates the system at the programmed regeneration timeafter the calculated system capacity is depleted. As with MeterImmediate systems, the control calculates the system capacityby dividing the unit capacity by the feedwater hardness andsubtracting the reserve. The reserve should be set to insurethat the system delivers treated water between the time thesystem capacity is depleted and the actual regeneration time. AMeter Delayed control will also start a regeneration cycle at theprogrammed regeneration time if a number of days equal to theregeneration day override pass before water usage depletesthe calculated system capacity.Time Clock Delayed ControlA Time Clock Delayed Control regenerates the system on atimed interval. The control will initiate a regeneration cycleat the programmed regeneration time when the number ofdays since the last regeneration equals the regeneration dayoverride value.Day of the Week ControlThis control regenerates the system on a weekly schedule.The schedule is defined in Master Programming by settingeach day to either “off” or “on.” The control will initiates aregeneration cycle on days that have been set to “on” at thespecified regeneration time.Control Operation During RegenerationDuring regeneration, the control displays a specialregeneration display. In this display, the control shows thecurrent regeneration step number the valve is advancing to,or has reached, and the time remaining in that step. The stepnumber that displays flashes until the valve completes drivingto this regeneration step position. Once all regeneration stepsare complete the valve returns to service and resumes normaloperation.Pressing the Extra Cycle button during a regeneration cycleimmediately advances the valve to the next cycle step positionand resumes normal step timing.Control Operation During ProgrammingThe control only enters the Program Mode with the valve inservice. While in the Program Mode, the control continuesto operate normally monitoring water usage and keeping alldisplays up to date. Control programming is stored in memorypermanently, eliminating the need for battery backup power.4 JE11 Fleck 5600SXT DownflowManually Initiating a Regeneration1.
