Product Information

The Nitrate, Sulfate & Fluoride Reduction System by Franklin Water Treatment, LLC is designed to improve water quality by reducing nitrate, sulfate, and fluoride levels. The system includes a mineral tank with nitrate selective anion resin, a brine tank with a salt shelf and brine well, a digital backwashing control valve with a bypass valve, plumbing adapters, drain line, and brine line.

Successful Application The control valve of the system will periodically go through regeneration, which is factory preset to 3:30 A.M. The time of regeneration can be changed if needed.

Location Considerations When selecting the installation location for the system, the following factors should be considered:

  1. The system must be installed after the pressure tank in a private well system.
  2. The system should be installed after any other water treatment equipment except reverse osmosis.
  3. If chlorine is present in the supply water, a whole house carbon filter should be installed before the system.
  4. The system must not be exposed to freezing temperatures.
  5. Ensure that any in-line filter installed prior to the system does not restrict the flow or pressure required for backwashing.
  6. The system should be installed close to an adequate floor or laundry drain capable of handling the backwash cycle volume and flow rate. An air gap should be provided between the drain line and plumbing drain.
  7. Appliances requiring extended periods of continuous or high flow water use should bypass all water conditioning equipment unless the equipment has been specifically designed for that purpose.

Product Usage Instructions

General Installation Instructions Follow these instructions for the general installation of the system:

  • 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 using any type of lubricants, including silicone, on red or clear lip seals.
  • The nuts and caps can be unscrewed or tightened by hand or with the special plastic Service Wrench (CV3193, not included). If needed, pliers can be used to unscrew the nut or cap. Do not use a pipe wrench to tighten nuts or caps. Do not place a screwdriver in slots on caps and/or tap with a hammer.
  • If the plumbing system is used as the ground leg of the electric supply, maintain continuity by installing ground straps around any non-conductive plastic piping or bypass used in the installation.
  • Make sure the system is not installed backwards. Arrows molded into the valve body indicate the direction of flow.

Pre-installation Instructions

Description of the system
The PNR1 system includes a mineral tank (with gravel, distributor and nitrate selective anion resin), brine tank (with salt shelf, brine well, brine tank lid and safety brine valve), a mineral tank with digital backwashing control valve with bypass valve, plumbing adapters, drain line and brine line.

Successful Application
The PNR1 system is designed to reduce nitrate, sulfate and chloride levels in potable water through anion exchange. Water softener salt is required to regenerate the anion resin, but the PNR1 is NOT A WATER SOFTENER. It exchanges chloride (taken from the brine used for regeneration) for nitrate, sulfate and fluoride anions. The water being supplied to the PNR1 system must be; soft, iron free, manganese free, tannin free, have less than 0.5 ppm chlorine and be filtered to 5 microns. Pre-treatment equipment is always required and post- treatment with reverse osmosis may be required if TDS level exceeds 500 ppm after treatment or if a salty taste occurs when used in combination with a softener due to the addition of sodium and chloride to the drinking water.

Time of Regeneration
Periodically the control valve will go through regeneration. Regeneration is factory preset to 3:30 A.M. The time of regeneration may be changed if needed (see programming procedures on pages 9 – 10).

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

  1. The system must be installed after the pressure tank (private well system only).
  2. The system should be installed after any other water treatment equipment except reverse osmosis.
  3. If chlorine is present in the supply water a whole house carbon filter should be installed before the system.
  4. The system must not be subject to freezing temperatures.
  5. Ensure that any in-line filter installed prior to the system does not restrict the flow or pressure required to backwash the system.
  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 page 11). 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 system 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 connections or 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 system is not installed backwards. The system will not function properly if installed backwards and anion 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

Detailed Installation Instructions

  1. STEP 1: Carefully remove all components from packaging. DO NOT DISCARD PACKAGING until all nitrate reduction system components and fittings have been located.

  2. STEP 2: Using the integrated coupling nuts, attach the bypass valve to the inlet/outlet of the control valve and put handles in the bypass position (Figure 2).

  3. STEP 3: Place unit at desired installation position.

  4. STEP 4: Shut off water at main supply. Relieve pressure by opening nearest faucet. On private well systems, turn off power to pump and drain pressure tank. SHUT OFF POWER OR FUEL SUPPLY TO WATER HEATER.

  5. STEP 5: Cut main supply line as required to fit plumbing to inlet and outlet of bypass valve. DO NOT PLUMB INLET AND OUTLET BACKWARDS. Piping should be supported. Do not apply heat to any fitting attached to the bypass or control valve.

  6. STEP 6: Use the provided polyethylene tubing (NO VINYL TUBING) to run drain line from control valve drain fitting (Figure 2) to floor drain or sump pit capable of handling the backwash rate of the system (refer to specifications on Page 11). THE DISCHARGE END OF THE DRAIN LINE MUST BE FIRMLY SECURED! There must be an air gap at the end of the drain line to prevent siphoning of wastewater and meet plumbing code. Total length of drain line should be 15’ or less. AVOID OVERHEAD DRAINS.STERLING-PNR1-Series-Nitrate-Sulfate-and-Fluoride-Reduction-System-FIG- \(4\)

  7. STEP 7: Connect one end of the 3/8” brine line to the control valve quick connect brine refill elbow (Figure 2, Page 4). Insert the other end of the brine line through the hole in the brine tank and into the quick connect fitting on the top of the safety brine valve (Figure 3). Remove the quick connect collet retainer clip (if included) before inserting the brine line into each fitting, press the tube in very firmly and replace the retainer clip behind the collet. NOTE: THE BRINE TUBING SHOULD BE INSERTED 5/8” INTO THE FITTING. DO NOT PUT SALT INTO THE BRINE TANK AT THIS TIME.STERLING-PNR1-Series-Nitrate-Sulfate-and-Fluoride-Reduction-System-FIG- \(5\)

  8. STEP 8: If desired, install overflow tubing (not provided) from overflow elbow on brine tank (Figure 3) to floor drain. Tubing must be lower than the overflow elbow at all times. DO NOT CONNECT DRAIN LINE FROM SYSTEM CONTROL VALVE TO BRINE TANK OVERFLOW. DO NOT CONNECT BRINE TANK DRAIN LINE TO THE SYSTEM DRAIN LINE.

  9. STEP 9: Plug the transformer into an un-switched electrical outlet. Ensure the control valve is in “Service” mode (display will alternate between time, gallons remaining, days remaining and flow rate).

  10. STEP 10: Place the bypass valve in the “Service” position (refer to Figure 4a, Page 7) and open main supply valve or turn on power to pump on private well systems. Allow the unit to fill with water and pressurize, then place the bypass valve in the “Bypass” position.

  11. STEP 11: Add water in the brine tank to slightly above the top level of the salt grid (approx. 5 – 6 gallons for units without a salt grid). DO NOT ADD SALT TO THE BRINE TANK AT THIS TIME.

  12. STEP 12: With the bypass valve in the “Bypass” position (refer to Figure 4a, Page 7), press and hold the REGEN button until the motor starts. Then use the REGEN button to advance the control valve to the BACKWASH cycle to release pressure and purge air from the mineral tank.

  13. STEP 13: Refer to Figure 4, Page 7 for bypass valve operation. Rotate the INLET knob of the bypass valve slowly to the “Service” position (Figure 4a). If any air spurts or any resin is expelled to the drain, stop turning the knob until only water flows to the drain, then continue turning the knob fully to the “Service” position.

  14. STEP 14: When all air has been purged from the system and only water is running to the drain, turn the OUTLET knob of the bypass valve to the “Service” position also. Allow the system to backwash for a few minutes or until the drain water runs clear.

  15. STEP 15: Using the REGEN button, advance the control valve to the REGENERANT DRAW DN (downflow brine draw) cycle. Verify that the water level in the brine tank is slowly dropping (less than ½ gpm). Allow water level to drop below the top of the salt grid before continuing. If the water level does not drop, refer to page 18 for Troubleshooting. After verifying water level is dropping, use the REGEN button to advance past the BACKWASH 2, RINSE AND 5 second FILL cycle to the normal service display.
    ADD SALT TO BRINE TANK NOW. Any type of water softener salt may be used

  16. STEP 16: Check for leaks and correct as necessary.

  17. STEP 17: Turn power or fuel supply back on to water heater.

  18. STEP 18: Press and hold the NEXT and UP buttons together until the screen changes to input the adjusted grain equivalent of anions in the water on the WATER HARDNESS screen (refer to calculation under Installer Settings, Page 9, for details), then press NEXT to set the maximum DAYS BETWEEN REGENERATIONS based on the calculation on page 10. Then press NEXT repeatedly until the time of day is displayed.

  19. STEP 19: Press the CLOCK button to set the current time of day. (Page 9, note AM and PM).

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 nitrate reduction system or filter. During the regeneration cycle this position provides regeneration water to the unit, while also providing untreated water to the distribution system (Fig. 4a).

  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. 4b).

  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. 4c) . 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 system being in regeneration could cause a siphoning of brine into the building. If water is available on the outlet side of the system it is an indication of water bypassing the system (Fig. 4d)STERLING-PNR1-Series-Nitrate-Sulfate-and-Fluoride-Reduction-System-FIG- \(6\)

General Operation

USER DISPLAYS
When the system is operating, one of several displays may be shown. Pressing NEXT will alternate between the displays. One of the displays is the current time of day. The second display shows days to a regen/gallons remaining. Days To A Regen is the number of days left before the system goes through a regeneration cycle. Capacity remaining is the number of gallons that will be treated before the system goes through a regeneration cycle. The third display is current flow in gal/min. The user can scroll between the displays as desired by pushing NEXT or display will scroll automatically. When water is being treated (i.e. water is flowing through the system) the word “GPM” flashes on left side of display when other than flow rate is displayed. User screens will continuously scroll, switching views every 3 seconds. If the screens are manually scrolled, this screen will remain constant for 5 minutes then continue to scroll. The conditional screens will take precedence over the scrolling and the conditional conditions will apply. To manually reduce capacity, press down button while capacity remaining or days to a regen is displayed.STERLING-PNR1-Series-Nitrate-Sulfate-and-Fluoride-Reduction-
System-FIG- \(7\)

MANUAL REGENERATION

Sometimes there is a need to regenerate the system sooner than when the system calls for it, usually referred to as manual regeneration. There may be a period of heavy water usage because of guests or a heavy laundry day. To initiate a manual regeneration at the preset delayed regeneration time, press and release “REGEN”. The words “REGEN TODAY” will flash in left corner of display as it scrolls through displays 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 request. To initiate a manual regeneration immediately, press and hold the “REGEN” button for five seconds. The system will begin to regenerate immediately. The request cannot be cancelled. You must cycle all the way through the cycles to make it stop.
PLEASE NOTE : This will reset the meter. Note: If the salt tank does not contain salt, fill with salt and wait at least two hours before regenerating. If two regenerations are desired within 24 hour period, press /release REGEN button. REGEN TODAY will flash on screen. Press and hold REGEN button until valve initiates an immediate regeneration.
