Pre-installation Instructions

Description of the softener
The softener system includes a mineral tank (with gravel, distributor and softener resin), brine tank (with salt shelf, brine well, brine tank lid and safety brine valve), and a meter initiated electronic backwashing control valve with bypass and brine line.

Successful Application
Softeners are designed to remove hardness minerals (calcium and magnesium) from water by the process of ion exchange. They may also remove small amounts of “clear water” iron (2 ppm or less). Softeners are not designed to remove “red water” iron or bacterial iron. If greater levels of iron, “red water” or iron bacteria are present, an iron filter (OXY3) must precede the softener. Softeners are not designed to remove particulates. If there is any sediment or turbidity present in the water, a backwashing filter (FBW) with appropriate media must precede the softener. Only specialty tannin softeners are designed to remove tannins and the yellow to tea color from water. Softeners will not reduce hydrogen sulfide (“rotten egg” odor).

Time of Regeneration
Periodically the control valve will go through regeneration. Regeneration is factory preset to 2:00 A.M. The time of regeneration may be changed if needed (see programming procedures on page 8)

Location Considerations
The proper location to install the softener will ensure optimum performance and satisfactory water quality. The following factors should be considered in selecting the location of this system.

  1. The softener must be installed after the pressure tank (private well system only).
  2. The softener should be installed after any iron filter and/or other backwashing filter.
  3. If chlorine is present in the supply water a whole house carbon filter should be installed before the softener.
  4. The system must not be subject to freezing temperatures
  5. Ensure that any in-line filter installed prior to the softener does not restrict the flow or pressure required to backwash the softener.
  6. The system should be installed as close as possible (preferably within 15’) to an adequate floor or laundry drain capable of handling the backwash cycle volume and flow rate (refer to unit specifications on pages 13-14). An air gap should be provided between the drain line and plumbing drain.
  7. All water conditioning equipment should be installed at least 10’ prior to the water heater. Water temperatures exceeding 100°F can damage the internal components of the control valve and mineral tank. An expansion tank may need to be installed in the line to the water heater in order to allow for thermal expansion and comply with local plumbing codes.
  8. Appliances requiring extended periods of continuous or high flow water use (i.e. geothermal heat pumps, swimming pools, lawn irrigation, outside hose bibs, etc.) should bypass all water conditioning equipment unless the equipment has been specifically designed for that purpose.

General Installation Instructions

GENERAL INSTALLATION & SERVICE WARNINGS

The softener is not designed to support the weight of plumbing.

Do not use Vaseline, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may be used on black “O” Rings, but is not necessary. Avoid any type of lubricants, including silicone, on red or clear lip seals.

Do not use pipe dope or other sealants on threads. Teflon® tape must be used on the threads of the 1″ NPT
inlet and outlet and on the threads for the drain line connection. Teflon® tape is not used on the nut connectionsor caps because “O” Ring seals are used.

The nuts and caps are designed to be unscrewed or tightened by hand or with the special plastic Service Wrench, (CV3193, not included). If necessary, pliers can be used to unscrew the nut or cap. Do not use a pipe wrench to tighten nuts or caps. Do not place screwdriver in slots on caps and/or tap with a hammer.

NOTE: If the plumbing system is used as the ground leg of the electric supply, continuity should be maintained by installing ground straps around any non-conductive plastic piping or bypass used in the installation. Make sure the softener is not installed backwards. The softener will not function properly if installed backwards and softener resin may be forced into the water lines. Arrows molded into the valve body indicate the direction of flow.

Site Requirements

  • water pressure — 25-100 psi (1.7 – 6.9 bar)
  • water temperature — 33-100°F (0.5-37.7°C)
  • electrical — 115/120 V, 60 Hz uninterrupted outlet dry locations only
  • the tank should be on a firm level surface
Typical Installation

FIGURE 1: Typical Installation

Bypass Valve

The bypass valve is used to isolate the control valve from the plumbing system’s water pressure in order to perform control valve repairs or maintenance. The 1″ full flow bypass valve incorporates four positions including a diagnostic position that allows a service technician to have pressure to test a system while providing untreated bypass water to the building. Be sure to install bypass valve onto main control valve, before beginning plumbing or make provisions in the plumbing system for a bypass. The bypass body and rotors are glass filled Noryl® and the nuts and caps are glass filled polypropylene. All seals are self-lubricating EPDM to help prevent valve seizing after long periods of non-use. Internal “O” Rings can easily be replaced if service is required. The bypass consists of two interchangeable plug valves that are operated independently by red arrow shaped handles. The handles identify the direction of flow. The plug valves enable the bypass valve to operate in four positions

  1. Normal Operation Position: The inlet and outlet handles point in the direction of flow indicated by the engraved arrows on the control valve. Water flows through the control valve for normal operation of a water softener or filter. During the regeneration cycle this position provides regeneration water to the unit, while also providing untreated water to the distribution system (Fig. 2 ).

  2. Bypass Position: The inlet and outlet handles point to the center of the bypass. The system is isolated from the water pressure in the plumbing system. Untreated water is supplied to the building (Fig. 3 ).

  3. Diagnostic Position: The inlet handle points toward the control valve and the outlet handle points to the center of bypass valve. Untreated supply water is allowed to flow to the system and to the building, while not allowing water to exit from the system to the building (Fig. 4 ) . This allows the service technician to draw brine and perform other tests without the test water going to the building.
    NOTE: The system must be run through a rinse cycle before returning the bypass valve to the normal position.

  4. Shut Off Position: The inlet handle points to the center of the bypass valve and the outlet handle points away from the control valve. The water is shut off to the building. The water treatment system will depressurize upon opening a tap in the building. A negative pressure in the building combined with the softener being in regeneration could cause a siphoning of brine into the building. If water is available on the outlet side of the softener it is an indication of water bypassing the system (Fig. 5 )

Installation Instructions

STEP 1:
Unpack softener, making sure to remove entire contents of the shipping container prior to disposal.

STEP 2:
Fill the resin tank. Cover the top of the distributor tube with the included red cap and, using the included blue media funnel, pour the included softener resin into the mineral tank.

STEP 3:
Install the control valve. Clean resin tank threads to remove any resin beads. Remove red cap from distributor tube and install control valve by threading it securely onto the mineral tank. (O-ring seal; HAND TIGHTEN ONLY!).

STEP 4:
Install bypass valve onto main control valve, before beginning plumbing. Make provisions to bypass outside hydrant and cold hard water lines at this time

STEP 5:
Shut off all water at main supply. On private well system, turn off power to pump and drain pressure tank. Make certain pressure is relieved from complete system by opening nearest faucet to drain system. SHUT OFF FUEL / ELECTRICAL SUPPLY TO WATER HEATER.

STEP 6:
Plumb the water supply line to the unit’s bypass valve inlet located at the right rear as you  face the unit. There are a variety of installation fittings available. They are listed under Installation Fitting Assemblies, pages 21-23. When assembling the installation fitting package (inlet and outlet), connect the fitting to the plumbing system first and then attach the nut, split ring, and “O” Ring. Heat from soldering or solvent cements may damage the nut, split ring, or “O” Ring. Solder joints should be cool and solvent cements should be set before installing the nut, split ring, and “O” Ring. Avoid getting solder flux, primer, and solvent cement on any part of the “O” Rings, split rings, bypass valve, or control valve. If the building’s electrical system isgrounded to the plumbing, install a copper grounding strap from the inlet to the outlet pipe. Plumbing must be done in accordance with all applicable local codes. MAKE CERTAIN WATER ENTERS THROUGH INLET AND DISCHARGES THROUGH OUTLET
FIGURE 6: Top View of Control Valve with Bypass Installed

STEP 7:
Apply thread tape to DLFC Assembly. Remove drain line flow control (DLFC) retainer clip (Figure 6, Page 5) and remove the DLFC assembly from the valve body, (Figure 6, Page 5). Apply thread tape to threads. Slide drain fitting compression nut onto provided drain tubing and place the tube insert inside the end of the tubing. Insert tubing end with insert into drain elbow and tighten the compression nut onto the thread taped elbow. Reinsert DLFC assembly into the valve body, making certain it is FULLY inserted before replacing the retaining clip.

STEP 8:
Install softener drain line. Use ½” I.D. polyethylene tubing (DO NOT USE FLEXIBLE VINYL TUBING!) to run drain line from control valve DLFC fitting (Figure 6, Page 5, not shown) to floor drain or sump pit capable of handling the backwash rate of the filter (refer to specificationsand flow rate on pages 15-16) or discard the compression fitting and use 3/4″ NPT fitting to connect a rigid pipe drain line (recommended). If backwash flow rate is greater than 7 gpm, use ¾” NPT connector with rigid drain line. There must be an air gap at the end of the drain line to prevent siphoning of waste water. Length of drain line should be 15’ or less. AVOID OVERHEAD DRAINS.

STEP 9:
Connect brine line between the softener and safety brine valve. Install the 3/8″ O.D. polyethylene tube from the brine refill elbow (Figure 6, Page 5) to the safety brine valve (Figure 7) inside the brine tank. DO NOT INSERT THE BRINE REFILL LINE INTO THE BRINE TANK OVERFLOW ELBOW FITTING. Do not put salt in the tank until STEP 25.
FIGURE 7: Brine Tank Components

STEP 10:
Install brine tank overflow drain line (not included). An overflow drain line is recommended. The softener includes a safety brine valve (Figure 7) which reduces the chance of a brine overflow. In the event of a malfunction, an overflow drain line will direct the “overflow” to the drain instead of onto the floor where it could cause considerable damage. This fitting is an elbow on the side of the brine tank (Figure 7). Attach a length of 1/2″ I.D. tubing to fitting and run to a drain. Do not elevate overflow line higher than 3″ below bottom of overflow fitting. DO NOT “TIE” THIS TUBE INTO THE DRAIN LINE OF THE CONTROL VALVE AS IT WILL RESULT IN OVERFILLING THE BRINE TANK AND FLOODING. The overflow line must be a direct, separate line from the brine tank overflow elbow to a floor drain or sump pit.

STEP 11:
With the bypass valve handles in the bypass position (Figure 3, Page 4), turn on water supply. Turn the inlet bypass valve handle to the diagnostic position (Figure 4, Page 4) and allow the softener to pressurize. NOTE: the INLET and OUTLET knobs turn clockwise to close the port to the softener and counter- clockwise to open the port to the softener. Check for leaks and correct as needed. Return the inlet bypass valve handle to the bypass position.

STEP 12:
Program control valve. Plug the transformer of the control valve into an uninterrupted electrical outlet (not wired to a switch) and use the buttons on the front of the control valve to adjust the initial settings:

    a. The upper left of the display will show “TIME”
    b. The current time of day will be shown on the right side of the display
    c. Only the colon between the hour and minutes will be flashing

STEP 13:
Initiate Manual Regeneration (Fill Cycle): (NOTE:, the bypass should be in the bypass position) Press and hold the “REGEN” button 3 seconds or until the word “Fill” appears in the lower right of the display and “REGEN” appears at the middle left of the display. The drive motor will run briefly and count-down timer will appear in the time-of-day position on the display. Press the “REGEN” button briefly. The control valve will advance to the next cycle.

STEP 14:
Softening Cycle: “SOFTENING” will appear in the upper left of the display and “REGEN” in the middle left. Another count-down timer will appear in the time- of-day position of the display. Make sure the bypass handles are in the bypass position (Figure 3, Page 4)! Press the “REGEN” button to advance the control valve to the “BACKWASH” cycle.

STEP 15:
Backwash Cycle: There will be an audible release of pressure to the drain. “BACKWASH” will be shown in the lower middle of the display and “REGEN” appears in the middle left of the display. Another count-down timer will appear in the time-of-day position. Unplug the transformer from the electrical outlet. Slowly turn the INLET knob of the bypass, counterclockwise, to a point approximately 1/3 of the way between “Bypass” and “Service” positions (Figure 2, Page 4) or until the remaining air is released from the tank. When only water flows to the drain; gradually turn the INLET knob of the bypass valve counter-clockwise until it is fully in “Service” position (Figure 2, Page 4). Then turn the OUTLET knob of the bypass valve counter-clockwise until it is fully in the “Service” position (Figure 2, Page 4). When the water flowing to drain runs clear, plug the transformer back into the electrical outlet. Press the “REGEN” button to advance to the “Brine Draw” cycle.

STEP 16:
Brine Cycle: “BRINE” will appear in the lower right of the display, “REGEN” will show in themiddle left of the display and a new count-down timer will flash alternating with the letters “dn”. Press “REGEN” to advance to the second “Backwash” cycle.

STEP 17:
Backwash Cycle 2: “BACKWASH” will be shown in the lower middle of the display and“REGEN” appears in the middle left of the display. Another count-down timer will appear in the time-of-day position. Press “REGEN” to advance to the “Rinse” cycle.

STEP 18:
Rinse Cycle: Another count-down timer will appear in the time-of-day position, “RINSE” will be shown in the lower middle of the display and “REGEN” appears in the middle left of the display. Press the “REGEN” button to exit manual regeneration.

STEP 19:
Exit Manual Regeneration: The right side of the display will be blank and “SOFTENING” will flash in the upper left of the display, “REGEN” will appear in the middle left of the display and the drive motor will run for a few seconds until the current time-of-day is shown on the right side of the display and “TIME” is shown in the upper left of the display.

STEP 20:
Initiate Manual Regeneration (Fill Cycle): (NOTE: bypass should be in service position) Press and hold the “REGEN” button 3 seconds or until the word “Fill” appears in the lower right of the display and “REGEN” appears at the middle left of the display. The drive motor will run briefly and count-down timer will appear in the time-of-day position on the display. Allow the cycle to complete and advance to the next step automatically. If water does not fill to a point above the salt grid (if applicable), add some water manually to have at least 1 or 2 inches of water above the grid or a total of approximately 6 inches if no grid is present.

STEP 21:
Backwash Cycle: “BACKWASH” will be shown in the lower middle of the display and “REGEN” appears in the middle left of the display. Another count-down timer will appear in the time-of-day position. Press the “REGEN” button to advance to the “Brine Draw” cycle.

STEP 22:
Brine Cycle: “BRINE” will appear in the lower right of the display, “REGEN” will show in the middle left of the display and a new count-down timer will flash alternating with the letters “dn”. Allow this cycle to run until the water in the brine tank is drawn below the salt grid and then press “REGEN” briefly to advance to the second “Backwash” cycle.

IMPORTANT: If water is NOT drawn below the grid (or down to the air check) within 15 – 30 minutes (depending on softener size); complete step 24 of the installation and refer to the “Brine Tank Overfill” section of Troubleshooting (page 12) to resolve this problem. Failure to do so will prevent the softener from functioning properly. Test the solution by returning to STEP 20 and proceeding from there.

STEP 23 Backwash Cycle 2:
“BACKWASH” will be shown in the lower middle of the display and “REGEN” appears in the middle left of the display. Another count-down timer will appear in the time-of-day position. Press “REGEN” to advance to the “Rinse” cycle.

STEP 24:
Rinse Cycle: Another count-down timer will appear in the time-of-day position, “RINSE” will be shown in the lower middle of the display and “REGEN” appears in the middle left of the display. Press the “REGEN” button to exit manual regeneration.

STEP 25:
Add salt to brine tank. Fill the brine tank with salt. Any type of softening salt may be used. Solar salt is recommended to minimize frequency of brine tank cleanout.

STEP 26:
TURN ON FUEL / ELECTRICAL SUPPLY TO WATER HEATER

Control Valve Operating Displays

General Operation:

When the system is operating, one of two displays may be shown. Pressing next will alternate between displays. One of the displays is always the current time of day. The other display shows the current volume remaining in Gallons. Capacity remaining is the gallons that will be treated before the system goes through a regeneration cycle. The user can switch between the displays as desired.

If the system has called for a regeneration that will occur at the preset time of regeneration, the words REGEN TODAY will appear on the display.

The softener has an installed water meter, the word “Softening” flashes on the display when water is being treated (i.e. water is flowing though the system).

Regeneration Mode:
Typically a system is set to regenerate at a time of no water use. If there is a demand for water when the system is regenerating, untreated water will be delivered. When the system begins to regenerate, the display will change to include information about the step of the regeneration process and the time remaining for that step to be completed. The system runs through the steps automatically and will reset itself to provide treated water when the regeneration has been completed.

Manual Regeneration:
Sometimes there is a need to regenerate before the control valve calls for it. This may be needed if a period of heavy water use is anticipated or when the system has been operated without salt.

  • To initiate a manual regeneration at the preset delayed regeneration time, press and release regen. The words “REGEN TODAY” will flash on the display to indicate that the system will regenerate at the preset delayed regeneration time.
  • If you pressed the regen button in error, pressing the button again will cancel the command.
  • To initiate an immediate manual regeneration, press and hold the regen button for three seconds. The system will begin to regenerate immediately. This command cannot be cancelled.

Power Loss:
If the power goes out for less than two hours, the systemwill automatically reset itself. If an extended power outage occurs, the time of day will flash on and off which indicated the time of day should be reset. The system will remember all other settings.

Error Message: If the word “ERROR” and a number are alternately flashing on the display, record the number and contract the dealer for help. This indicates that the control valve was not able to function properly.
