The manufacturer reserves the right to make changes at any time without notice. This manual is intended as a guide for service of the valve only. System installation requires information from a number ofsuppliers not known at the time of manufacture. This product should be installed by a plumbing professional. This unit is designed to be installed on potable water systems only. This product must be installed in compliance with all state and municipal plumbing and electrical codes. Permits may berequired at the time of installation. If daytime operating pressure exceeds 80 psi, nighttime pressures may exceed pressure limits. A pressure reducing valve mustbe installed. Do not install the unit where temperatures may drop below 32 F (0 C) or above 110 F (43 C). Do not place the unit in direct sunlight. Black units will absorb radiant heat increasing internal temperatures. Do not strike the valve or any of the components. Warranty of this product extends to manufacturing defects. Misapplication of this product may result in failure to properlycondition water, or damage to product. A prefilter should be used on installations in which free solids are present. In some applications local municipalities treat water with Chloramines. High Chloramine levels may damage valve components. Correct and constant voltage must be supplied to the control valve to maintain proper function.

Installation InstructionsWATER PRESSURE: A minimum of 20 pounds of water pressure is required for regeneration valve to operateeffectively.ELECTRICAL FACILITIES: An uninterrupted alternating current (A/C) supply is required. Note: Other voltages areavailable. Please make sure your voltage supply is compatible with your unit before installation.EXISTING PLUMBING: Condition of existing plumbing should be free from lime and iron buildup. Piping that is builtup heavily with lime and/or iron should be replaced. If piping is clogged with iron, a separate iron filter unit should beinstalled ahead of the water softener.LOCATION OF SOFTENER AND DRAIN: The softener should be located close to a drain to prevent air breaks andback flow.BY-PASS VALVES: Always provide for the installation of a by-pass valve if unit is not equipped with one.CAUTION: Water pressure is not to exceed 125 psi, water temperature is not to exceed 110 F, and the unit cannot besubjected to freezing conditions.Installation Instructions1.Place the softener tank where you want to install the unit making sure the unit is level and on a firm base.2.During cold weather, the installer should warm the valve to room temperature before operating.3.All plumbing should be done in accordance with local plumbing codes. The pipe size for residential drain line shouldbe a minimum of 1/2”. Backwash flow rates in excess of 7 gpm or length in excess of 20’ require 3/4” drain line.Commercial drain lines should be the same size as the drain line flow control.4.Refer to the dimensional drawing for cutting height of the distributor tube. If there is nodimensional drawing, cut the distributor 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 ontank. Note: Only use silicone lubricant.6.Solder joints near the drain must be done prior to connecting the Drain Line Flow Controlfitting (DLFC). Leave at least 6” between the DLFC and solder joints when soldering pipesthat are connected on the DLFC. Failure to do this could cause interior damage to theDLFC.7.Teflon tape is the only sealant to be used on the drain fitting. The drain from twin tank unitsmay be run through a common line.8.Make sure that the floor is clean beneath the salt storage tank and that it is level.9.Place approximately 1” of water above the grid plate. If a grid is not utilized, fill to the top ofthe air check in the salt tank. Do not add salt to the brine tank at this time.10. On units with a by-pass, place in by-pass position. Turn on the main water supply. Open acold soft water tap nearby and let run a few minutes or until the system is free from foreignmaterial (usually solder) that may have resulted from the installation. Once clean, close thewater tap.11. Slowly place the by-pass in service position and let water flow into the mineral tank. Whenwater flow stops, slowly open a cold water tap nearby and let run until the air is purged fromthe unit.12. Plug unit into an electrical outlet. Note: All electrical connections must be connectedaccording to local codes. (Be certain the outlet is uninterrupted).Page NOTE: ResidentialAir Check ValvePictured Above

Start-Up InstructionsThe water softener should be installed with the inlet, outlet, and drain connections made in accordance with themanufacturer’s recommendations, and to meet applicable plumbing codes.1. Turn the manual regeneraton knob slowly in a clockwise direction until the program micro switch lifts on top ofthe first set of pins. Allow the drive motor to move the piston to the first regeneration step and stop. Each timethe program switch position changes, the valve will advance to the next regeneration step. Always allow themotor to stop before moving to the next set of pins or spaces.NOTE: For electronic valves, please refer to the manual regeneration part of the timer operationsection. If the valve came with a separate electronic timer service manual, refer to the timer operationsection of the electronic timer service manual.2. Position the valve to backwash. Ensure the drain line flow remains steady for 10 minutes or until the waterruns clear (see above).3. Position the valve to the brine / 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 the drain line flow, and run for 5 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 desiredrate. The brine valve drive cam will hold the valve in this position to 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.Page

During a power outage, the control goes into a power-saving mode. It does not monitor waterusage during a power failure, but it does store the volume remaining 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 of day, volume remaining or days to regeneration, andtank 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 datadisplay 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 thedata display will read “----”. Once the valve reaches the cycle step, the display will stop flashing and the datadisplay will change to the time remaining. During regeneration, the user can force the control to advance tothe next cycle step immediately by pressing the extra cycle button.Page

Timer FeaturesSetting the Time of Day1. Press and hold either the Up or Down buttons until the programming 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 button to resume normal operation. The unit will alsoreturn to normal operation after 5 seconds if no buttons are pressed.Queueing a Regeneration1. 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 ImmediatelyPress and hold the Extra Cycle button for five seconds.Page

Timer OperationMeter Immediate ControlA meter immediate control measures water usage and regenerates the system as soon as the calculated systemcapacity is depleted. The control calculates the system capacity by dividing the unit capacity (typically expressedin grains/unit volume)
