Successful Application
Any filter media may have specific limitations and/or requirements for successful application. Consult with technical services when selecting filter media for this system and the specific application.
Time of Regeneration
Periodically the control valve will go through a backwash cycle. This cycle is factory preset to 1:00 A.M. flushing the accumulated sediment and/or precipitant to the drain. After the backwashing process the unit is now prepared for the next period of service.

Water Supply
This filter will function properly when the water supply is furnished by a jet pump, submersible pump, variable speed (constant pressure) pump or community water supply. As with all other filter systems, however, it is imperative that the well pump provides enough flow rate for the filter to adequately backwash. To ensure sufficient backwash flow rate, the following pumping rate test should be performed prior to installing the POZ1.
Backwash flow rate required may vary from the installed DLFC depending on the media used with the filter.

  1. Make certain no water is being drawn in the house.
  2. Open spigot nearest pressure tank.
  3. When well pump starts, close spigot and measure time (in seconds) to refill pressure tank (well pump turns back off). This is Cycle Time.
  4. Using a container of known volume, draw water from pressure tank and measure how many gallons until the pump turns back on again. This is Draw Down.
  5. Calculate pumping rate by dividing draw down by cycle time and multiplying by 60.

Location Considerations
The proper location to install the POZ1 will ensure optimum filter performance and satisfactory water quality.
The following factors should be considered in selecting the location of this system.

  1. The POZ1 must be installed after the pressure tank (private well system only).
  2. 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). An air gap should be provided between the POZ1 drain line and plumbing drain.
  3. 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 filter tank. An expansion tank may need to be installed in the line to the water heater to allow for thermal expansion and comply with local plumbing codes.
  4. Water pressure must not exceed the range of 25 – 100 psi.
  5. The system must not be subject to freezing temperatures.
  6. The control valve requires 115/120 V, 60 Hz electricity from an outlet that is not wired to a switch.
  7. Never install a cartridge type filter prior to the POZ1. Any cartridge or in-line filter (if desired) may be installed after the POZ1 system. This will prevent restricting the water flow and pressure available for backwash.
  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 the filter.

General Installation

GENERAL INSTALLATION & SERVICE WARNINGS

The water conditioner 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. This will allow ease of installation and decrease chance of rolling from the bypass and tank connections. 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 may be used as required. Teflon® tape is not used on any connection where “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 filter is not installed backwards. The filter will not function properly if installed backwards and filter media may be forced into the service lines. Arrows molded into the valve body and red handles of the bypass indicate the direction of flow.
The POZ1 has a check valve (OV32) installed in the inlet of the control valve. This check valve will prevent hot water expansion in the plumbing. An expansion tank must be used on the water heater supply line to allow for thermal expansion.
All local plumbing codes must be followed.

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 filter 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 filter being in regeneration could cause a siphoning of brine into the building. If water is available on the outlet side of the filter it is an indication of water bypassing the system (Fig. 5)

Installation Instructions

STEP 1:
Unpack filter unit, making sure to remove entire contents of the shipping container prior to disposal.
STEP 2:
With the filter unit in the upright position, remove the control valve from the mineral tank being careful to not pull the distributor out of the gravel at the bottom of the tank. If the filter model has a “-DH” suffix, do not remove the control valve. Just remove the tank dome hole plug.
STEP 3:
If the control valve was removed, cover the top of the distributor tube with the included red cap. Using the included blue media funnel, pour filter media(s) into the mineral tank. If using multiple filter media types, load in the order of heaviest (most dense) to lightest (least dense). 14” of space MUST be left empty at the top of the mineral tank to allow for media bed expansion during backwash and to prevent filter media from being discharged through the drain line.
STEP 4:
Use a garden hose or bucket to fill the media tank with water.
IMPORTANT: Carbon, Filter Ag, Zeolite and Greensand Plus must be soaked for at least 2 hours prior to submitting it to full backwash flow rate to prevent loss of media to drain.
STEP 5:
Clean mineral tank threads to remove any filter media. If the control valve was removed, remove red cap from distributor tube and reinstall control valve by threading it securely onto the mineral tank. Otherwise simply replace the tank dome hole plug. (O-ring seal: HAND TIGHTEN ONLY!)
STEP 6:
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 7:
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 23-25. 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 is grounded 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.
STEP 8:
Apply thread tape to DLFC Assembly. Remove drain line flow control (DLFC) retainer clip (Figure 6, Page 7) and remove the DLFC assembly from the valve body, (Figure 6, Page 7). 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 9:
Install drain line. Use the provided ½” I.D. polyethylene tubing (DO NOT USE FLEXIBLE VINYL TUBING!) to run drain line from control valve DLFC fitting (Figure 6, Page 7) to floor drain or sump pit capable of handling the backwash rate of the filter (refer to specifications and flow rate on page 17) 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 10:
With the bypass valve handles in the bypass position (Figure 3, Page 5), turn on water supply. Turn the inlet bypass valve handle to the diagnostic position (Figure 4, Page 5) and allow the filter to pressurize. NOTE: the INLET and OUTLET knobs turn clockwise to close the port to the filter and counter- clockwise to open the port to the filter. Check for leaks and correct as needed. Return the inlet bypass valve handle to the bypass position.
STEP 11:
Program control valve. Plug the transformer of both the control valve and the ozone generator 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.

The drive motor will run briefly, and a count-down timer will appear in the lower right the display. There will be an audible release of pressure to the drain.
IMPORTANT: Carbon, Filter Ag, Zeolite and Greensand Plus must be soaked for at least 2 hours prior to submitting it to full backwash flow rate to prevent loss of media to drain.

STEP 13:
Unplug the transformer from the electrical outlet to keep the POZ1 in backwash for an extended time to purge any air and remove media “fines” (very small particles of media).
STEP 14:
Slowly turn the INLET knob of the bypass, counter-clockwise, to a point approximately 1/3 of the way between “Bypass” and “Service” positions (Figure 2, Page 5) or until the remaining air is released from the tank.
STEP 15:
Once the air is purged, gradually turn the INLET knob of the bypass valve counter-clockwise until it is fully in “Service” position (Figure 2, Page 5). Then turn the OUTLET knob of the bypass valve counter-clockwise until it is fully in the “Service” position (Figure 2, Page 5). and leave the control valve in “Backwash” position for at least 10 minutes or until water flowing from the drain line runs clear; whichever is longer.
STEP 16:
Regenerant Draw Cycle: Plug the transformer into the electrical outlet. DO NOT press the “REGEN” button to advance the control valve to the “REGENERANT DRAW DN” cycle. It must complete the backwash cycle and begin the regenerant draw cycle naturally in order for the ozone generator to turn on. Another count- down timer will appear in the time-of-day position, “REGENERANT DRAW DN” will be shown in the upper part the display.
STEP 17:
Complete Manual Regeneration: Allow the regeneration to complete and the filter will return to service mode automatically.
STEP 18:
TURN ON FUEL / ELECTRICAL SUPPLY TO WATER HEATER.

RECOMMENDED : Retain the red distributor cap and blue media funnel for future replenishment of filter media.
NOTE: If the POZ1 filter is loaded with any self-sacrificing media like Calcite or Iron Pro and the pH is less than 7, mark the media level on the side of the tank by shining a bright light through the tank to see its level. Replenish the media in the mineral tank when the level drops by more than three inches.

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 (depending on how it is programmed). 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.

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.

Maintenance

  1. If your unit contains activated carbon, you should replace the carbon and gravel underbed at least every three years. Replacement may be required sooner if the taste and odor being removed begins to reappear in the treated water or you experience increasing pressure drop that is not resolved by increasing the frequency of backwashing.
  2. Filter Ag, Zeolite and Filter Sand will last indefinitely. It may be necessary to replace them if you experience increasing pressure drop that is not resolved by increasing the frequency of backwashing or if water quality diminishes due to contaminant bleed through.
  3. Iron Pro media or calcite will need replenished with neutralizer media (N05, MPH30 or C05P) regularly in low pH water. Mark the side of the mineral tank at installation so the drop in media level may be monitored by shining a bright light behind the mineral tank. Add media if the level has dropped by more than three inches.
  4. Greensand Plus should be replaced when iron reappears in the treated water and backwashing does not improve the water quality or excessive pressure loss is experienced.

TO REPLENISH OR REBED MEDIA:

  1. Pressure must be relieved on the system by placing the Bypass Valve in the “Bypass” position (Figure 3, Page 5) and initiating a manual regeneration (section 3, page 10).

  2. Unplug the Control Valve from the electrical outlet to prevent it from advancing automatically.

  3. Disconnect the Control Valve from the Bypass Valve. If the unit has a “-DH” suffix in the model number and it only needs topped up with neutralizer media, DO NOT disconnect from the bypass valve.

  4. Disconnect the Drain Line from the Control Valve

  5. Unscrew Control Valve from Mineral Tank (IF REBEDDING ONLY! Remove the distributor). If the unit has a “-DH” suffix in the model number and it only needs topped up with neutralizer, DO NOT remove the control valve, just unscrew the dome hole plug instead.

  6. Siphon water from Mineral Tank (IF REBEDDING ONLY! Remove existing media and gravel).

  7. (IF REBEDDING ONLY! Rinse Mineral Tank and replace distributor, making certain that the distributor basket sits in the center of the tank bottom.)

  8. If the control valve was removed, cover the top of the distributor tube to prevent media entering the tube during filling. Using a funnel, pour filter media(s) into the mineral tank. (IF REBEDDING ONLY! Begin loading the tank with the gravel underbed. Filling the Mineral Tank 1/3 with water before loading gravel will cushion the fall and ensure even distribution of the gravel and media. If using multiple filter media types, load in the order of heaviest {most dense} to lightest {least dense}.) 14” of space MUST be left empty at the top of the mineral tank to allow for media bed expansion during backwash and to prevent filter media from being discharged through the drain line.

  9. Use a garden hose or bucket to fill the media tank with water.

  10. Clean mineral tank threads to remove any filter media. If control valve was removed, uncover distributor tube and reinstall control valve by threading it securely onto the mineral tank. “-DH” models that were only topped up with neutralizer on need the dome hole plug replaced. O-ring seal; HAND TIGHTEN ONLY in both cases!

  11.  If control valve was removed, attach bypass valve to control valve body.

  12. If control valve was removed, reattach Drain Line to Control Valve (Figure 6, Page 7).

  13. IMPORTANT! Carbon, Filter Ag, Zeolite and Greensand Plus must be soaked for at least 2 hours prior to submitting it to full backwash flow rate to prevent loss of media to drain.

  14. Gradually turn the INLET side knob of the bypass valve counter-clockwise not more than ½ way (45 degrees) to the “Service” position (Figure 2, Page 5) allowing unit to pressurize slowly. Check for leaks and correct as needed. Any air trapped in the media bed should begin purging to the drain and water should begin flowing to the drain.

  15. Once the air is purged, gradually turn the INLET knob of the bypass valve counter-clockwise until it is fully in “Service” position (Figure 2, Page 5). Then turn the OUTLET knob of the bypass valve counterclockwise until it is fully in the “Service” position
    (Figure 2, Page 5). and leave the control valve in “Backwash” position for at least 10 minutes or until water flowing from the drain line runs clear; whichever is longer.

  16. Plug the transformer into the electrical outlet. Press the “REGEN” button to advance the control valve to the “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. Allow the rinse cycle to complete and the filter will return to service mode automatically.

Recommended Annual Maintenance for Ozone Generator:

  • Verify injector is clean and functioning and injector screen is clean.
  • Clean / change CD cell (33218-R). Flush CD cells completely by pushing warm RO or soft water through CD cells to dissolve build-up inside. This can be done using a bulb syringe or large 60cc syringe. Flush until the water coming out is clear, usually takes 2-3 times. CD cell must be dry completely before it can be reinstalled, or cell will not produce ozone. Verify ozone production prior to changing CD cell to understand need for cleaning frequency at each application. Initiate regeneration, attach tubing to CD cell inlet and disconnect brine elbow during draw cycle and blow on tubing to detect ozone odor. Check that indicator light is working.
  • Change ozone check valves (at brine elbow, 47035 & OV15HT).
