What to Do if Your Tank is Not Level Out of the Box
Your black Nitrate Filter tank base is not glued to the bottom of your tank. Occasionally tank bases will become crooked during shipment. If you find that that your tank does not sit level on the floor, you can easily adjust it by holding the empty tank and rapping it on a concrete or solid floor once or twice to level it.

How Your Nitrate System Works

• In the nitrate system, water enters the top of the tank and flows down through the nitrate resin media and up the distributor tube.
• Nitrate and sulfate are removed by the resin beads in a process known as “ion exchange”.
• Nitrate and sulfate are removed and harmless chloride mineral is added (exchanged).
• During regeneration the first cycle in the process backwashes and cleans the nitrate resin.
• Water flow is reversed and water flows down the distributor tube and up through the media, lifting and expanding the resin and removing any trapped particles.
• After the backwash stage, salt brine is automatically drawn in from the brine tank which then slowly rinses through the softening resin for 1 hour, allowing the nitrate and sulfate to be exchanged with harmless chloride ions.
• After the brine tank is emptied it is refilled during the final cycle. The amount of water that is automatically refilled into the brine tank is controlled by the 5900-BT control valve and is adjustable. Each gallon of water dissolves 3 lbs of salt. Each cubic foot of nitrate resin requires 9 to 10 lbs of salt per regeneration.
• This entire automatic process, called ‘regeneration’ takes about 90 minutes.
• Typically the nitrate filter is set to regenerate based on gallons used and timed to occur during the middle of the night when no water is being used.

Nitrate Filter Installation Steps Overview

1. Verify that you have received all parts and there are no damaged or missing parts.
2. If your size Nitrate Filter uses gravel (48K grain and larger) add gravel first, then add softening resin. Fill tank with clean water. OK to soak for 1 hour up to 24 hours while doing piping.
3. Make the plumbing connections from your existing system to the bypass assembly, installing extra valves, unions, pressure gauges and hose bibs as needed.
4. Attach the control head to the tank, and to the bypass assembly.
5. Install the Drain Line tubing
6. Plug in the power supply and program the valve.
7. Follow the instructions to put the Nitrate Filter online and to verify the system is leak-free.

Pre-Installation

1. Review your packing list to make sure you have received all the parts before installation.
2. If you are going to be turning off the water to the house and you have an electric water heater, shut off the power to the water heater before beginning installation.
3. Pick a suitable location for your Nitrate Filter on a dry level spot where it won’t be exposed to freezing temperatures, direct sunlight, wind or rain.
4. Get all of your plumbing parts together before beginning installation.
5. After the system is installed and running, your water may be discolored, or full of sediment or rust, especially if you have older or corroded piping. This typically clears up over a day or two.

Best Practices for Piping & Drain Installation

1. See typical installation Page 7. If on well water, Nitrate Filter is installed after pressure tank.
2. Install on a level floor or surface.
3. Your new Nitrate Filter must be installed at least 10 feet ahead of inlet to water heater to prevent damage due to back-up hot water or use a check valve to prevent hot water back-up.
4. DO NOT install the unit in an area of direct sunlight or expose to freezing.
5. Make sure brine tank is set on a smooth surface with no sharp objects, rocks etc.
6. Locate the unit near an unswitched, 120 volt / 60 Hz grounded electrical outlet.
7. Nitrate Filter must be installed at least 10 feet ahead of inlet to water heater to prevent damage due to back-up hot water or use a check valve to prevent hot water back-up.
8. DO NOT install the unit in an area of direct sunlight or expose to freezing.
9. Locate the unit near an unswitched, 120 volt / 60 Hz grounded electrical outlet.
10. Make sure to connect the IN pipe to the 5900-BT inlet and the OUT pipe to the outlet.
11. Make sure there is a working gate or ball valve before the 5900-BT Nitrate Filter and also one after as shown in Fig 2. The pressure gauges are optional. A hose bib (which is a faucet that you can attach a garden hose to) is strongly recommended after the 5900-BT Nitrate Filter and before the second ball valve, for rinsing and sampling water.
12. If you will be using copper piping, do not sweat the copper pipe directly on to the 5900-BT control valve. Avoid heating up the 5900-BT control valve plastic with the torch.
13. You do not need unions to install your 5900-BT control valve. If you need to remove it, the 5900-BT has quick-release couplings that make it easy to put the Nitrate Filter on by-pass and remove the 5900-BT Nitrate Filter control valve from the piping.
14. The drain line tubing is connected to a drain from the drain outlet using flexible poly tubing. The drain can run up above the control head and out to a drain, although this may require installing a one way, flapper-stlye check valve. Most plumbing codes require an air-gap connection, so that if your sewer or septic tank backs up, it cannot cross connect with the drain tubing (if running tubing into the washing machine drain pipe, for example)

Nitrate Filter System Piping Diagram

Typical Well Water Installation – Install After Pressure Tank

Installation of Your Nitrate Filter into Copper or Metal Piping Systems

• If your new Nitrate Filter is to be installed in a metal (conductive) plumbing system, i.e. copper or galvanized steel pipe, the plastic components (bypass and connectors) will interrupt the electrical continuity of the plumbing system.
• As a result, any stray currents from improperly grounded appliances downstream or potential galvanic activity in the plumbing system can no longer ground through contiguous metal plumbing.
• Some homes may have been built in accordance with building codes which encouraged the grounding of electrical appliances through the plumbing system.
• The installation of a bypass consisting of the same material as the existing plumbing, or a grounded “jumper wire” bridging the equipment and reestablishing the contiguous conductive nature of the plumbing system must be installed prior to your systems use.
• A simple ground jumper wire with a pipe clamp can be purchased at any Home Center, or hardware store etc. for a few dollars.

Add Nitrate Resin and Install 5900-BT Backwash Valve on Tank

1. Make sure you “test fit” distributor tube, find divot that keeps tube centered, before adding gravel so distributor tube does not extend past top of tank.
2. There are two styles of funnel that we ship, depending on availability; you get either the blue or black funnel.
3. If blue funnel, cover top of distributor tube with black electrical tape, duct tape or masking tape so no gravel or media will go down distributor tube when adding media.
4. Leave a folded tab of tape so you can easily pull off tape after filling the tank.
5. Hold the tube center until there is enough gravel and media to support the tube. The top of the distributor tube should be level with the top opening of the Nitrate Filter tank.
6. Add the gravel (for 1.5 Cubic Foot 48K grain units and larger only) that came with your order. The gravel should cover the bottom distributor screen before adding the nitrate resin.
7. Next add the nitrate resin.
8. The tank should be about 2/3 to 3/4ths full of the resin.
9. Fill tank completely with water. Allow to soak for at least 1 hour up to 24 hours before you hook it up to piping.
10. Remove tape from top of distributor tube. Be careful not to pull up distributor tube.
11. Attach plastic top screen to under-side of the 5900-BT control valve. It is a funnel-shaped plastic screen that snaps on to the control valve and prevents resin from being backwashed out to drain during the regeneration cycles. It may twist on clockwise or counter-clockwise.
12. Screw on Control Valve: Add small amount of silicone grease to both O-rings (only O-rings, not tank thread) on bottom of control valve and screw on 5900-BT control valve carefully.
13. Do not lubricate tank threads or any other fittings other than O-rings. Do not use pipe-joint compound, vegetable oil, Teflon tape, or Vaseline or greases on tank threads.
14. If you accidentally pull distributor tube up after gravel and media are in tank (upon initial install or any time after, for service, etc.), it must be re-seated. It is usually possible to do this by spraying water down distributor tube with a garden hose while pushing on end of the tube. If this does not work, you must empty tank completely and start over.
15. Do not hard pipe the drain line with PVC or copper, use flexible tubing. If you use hard PVC piping for the drain line, you must able to remove the hard drain piping and attach flexible tubing for testing purposes.
16. Make sure the drain tubing is firmly clamped to the barbed fitting with a hose clamp to prevent leaks or blow-offs.

Attach the Bypass
Make sure there is lubricant on all three sets of O-rings and insert and screw bypass onto end connectors (O-rings are already on valve, with the Inlet Air Check Valve on the left, Inlet side). Screw the Elbow fittings onto the end of the bypass and attach to service pipe.
NOTE: There is supposed to be some “play” in the whole assembly. No need to over-tighten or to screw them too tight.

Piping Installation

1. Using Teflon tape on pipe threads, make sure to connect the IN pipe to inlet and OUT pipe to the outlet. As you face the 5900-BT control from the front, the water enters on the right and exits on the left. From the back the water enters on the left.
2. The inlet and outlet are attached to the bypass valve, which is marked with arrows as well.
3. Make sure there is a hose bib installed after the system, and a working gate or ball valve before and after the nitrate system. The pressure gauges are optional but a hose bib is strongly recommended after the 5900-BT control valve and before the second ball valve. This makes it easy to rinse your new system on start-up and gives you a place to test water before it enters your house plumbing.
4. If you will be using copper piping, do not sweat the copper pipe directly on to the 5900-BT control valve. Avoid heating up the control valve with the torch, as the plastic will melt.
5. You do not need unions to install your 5900-BT control valve. If you need to remove it, the 5900-BT control valve has quick-release couplings that make it easy to put the 5900-BT on by-pass and remove the nitrate filter from the piping.
6. The drain line tubing is connected to a drain from drain outlet using flexible tubing. Note that drain line can run up above the 5900-BT control and into a drain.
7. Most plumbing codes require an air-gap connection for the drain line tubing, so that if your sewer or septic tank backs up, it cannot connect with the drain tubing.

Attach the Brine Line Tubing to Brine Tank

Insert the 3/8” diameter tubing into the brine tank connection (included with your order). Screw the nut with the sleeve and ferrule attached to prevent leaking.

• On the control valve side: to connect the brine tank, begin by sliding the plastic brine injector nut on to the brine tubing by putting the tubing through the nonthreaded side of the nut first.
• Next, slide the white (or clear) compression ring on to the tubing with the wider diameter going on first.
• Insert the tubing into the brine nut and screw tight- do not over-tighten.
• On the brine tank: push the brine injector nut, which now has the compression rings inside of it, on to the threading of the brine tank float assembly and rotate the nut clockwise, screwing it on to the brine port on 5900-BT control valve.
• Tighten it down to finger tight. The tubing should be firmly attached and not slide out if pulled on.

Brine Tank Set Up

1. Add approximately 5 gallons of water to the brine tank, and then fill the brine tank with salt, add just one bag until after you have done the initial regeneration, then you can fill the brine tank about 2/3 full of salt, which will generally be enough for several months.
2. It is OK to use any kind of water softening salt; however, we find that extra coarse salt works better than pellets.
3. You do not have to add water to the brine tank again after this first time during the start-up.
4. See the over-flow barbed fitting on the side of the brine tank. You do not have to connect this to a drain.
5. If the safety float were to malfunction, there is a small chance that the brine solution will drip out of this fitting. If this would cause a big mess where you have installed the Nitrate Filter, hook some tubing to this and run to a bucket, floor pan or floor drain. Normally no brine will leak out of this fitting.

Exiting the Master Programming Mode
Press the Menu/Enter Button until all steps have been viewed. The Program Mode will be exited, and normal operation resumed. If no buttons are pressed for 60 seconds mode will be exited.

Start the First Regeneration

1. Close both the Inlet and Outlet valves, if not already closed. If days remaining is not already at 1 press and hold the Set/Change button. Now, press and hold the set change button again, until the valve begins the backwash cycle and the display reads 1 – 08.
2. Start to put the valve into the service position by turning inlet the bypass knob counterclockwise about a quarter inch, until you can hear water passing through the bypass into the softener. Stop and wait until you see water coming out of drain line. It will often be mixed with air bubbles.
3. When you do not see bubbles anymore, keep opening the valve, a little bit at a time, stopping for a minute or two each time. You want to see increase in flow out of the drain line as you increase the flow of water into softener. After several minutes, you should have valve fully open.
4. Cycle Step 2, the Brine Draw, is for 60 minutes. Confirm that the water in the brine tank is being sucked down; if you start with 5 gallons, it should be empty after 15 minutes. If it is not, test your tubing connections, and make sure float assembly is working. Once it has sucked salt water into softener, it will do a slow rinse for the rest of the cycle.
5. Allow the valve to finish running through the last two cycles: Rapid Rinse, 6 minutes and Brine Fill, minutes determined by softener size.
6. Open outlet on the bypass valve and then open the nearest treated water faucet to the unit and allow the water to run until it is clear. We advise using a bathtub, laundry sink, or other fixture that does not have an aerator screen as any remaining residue may get caught in the screen.

Normal Operation & Maintenance

• Normal display alternates between time of day and days until regeneration.
• Days remaining until the next regeneration will count down from the regeneration day override value to 1 day remaining. Once the count reaches 1, a regeneration cycle will be initiated at the next designated regeneration time.
• Make sure brine tank is regularly filled with salt.
• When brine tank is getting low on salt, refill to top.
• Test for nitrate levels before and after system monthly or at least quarterly with home test kit. Get untreated water and water after nitrate system professionally tested at a lab at least once a year. If untreated nitrate levels change, adjust program.
• Test brine suction and clean brine injector as needed, typically once a year.

How the Battery Back-up Works

• Uses a 9-volt battery, not included. 9-volt battery lead wires are found by removing the cover.
• Hook the battery up, it lays loose in the tray below the circuit board. The battery back-up maintains the time of day during power failures. Replace battery once per year. The battery back-up continues to count down gallons remaining during power failure (Metered Version).
• Menus cannot be accessed during power failure
• When the battery is installed, and the unit loses power, it will use the battery to advance the piston to the next cycle where no water is being used.

How to Start an Extra Regeneration Cycle

• If days remaining is not already at 1 press and hold the Set/Change button.
• After 3 seconds the days remaining display will read 1 Example [ 1 ]
• Regeneration cycle will be initiated at the next designated regeneration time
• Starting Immediate Extra Cycle: First, complete above delayed cycle steps
• With days remaining at 1 press and hold the Set/Change button
• After 3 seconds the regeneration cycle will begin.
• Fast Cycling Through Regeneration
• First complete above immediate cycle steps
• Press and hold the Set/Change button
• After 3 seconds the valve will start to advance to the next step

Troubleshooting Guide

Brine Solution Not Being Sucked in During Regeneration

Make sure the injector is drawing in the brine
Remove the brine tank tubing where it enters the 5900-BT control valve. Initiate a backwash and skip to the Brine Cycle by following the steps below:
Start delayed extra cycle
If days remaining is not already at 1 press and hold the Set/Change button. After 3 seconds the days remaining display will read 1 Example [ 1 ] Regeneration cycle will be initiated at the next designated regeneration time
Start Immediate Extra Cycle – First, complete above delayed cycle steps With days remaining at 1 press and hold the Set/Change button After 3 seconds the regeneration cycle will begin.
Fast Cycle Through Regeneration
First complete above immediate cycle steps Press and hold the Set/Change button After 3 seconds the valve will start to advance to the next step, which is the Brine Cycle, where it is supposed to suck in the brine solution.

1. If it is sucking strongly, check the brine tank float inside the brine well and make sure that is free of obstructions. In some cases, it may need to be replaced or cleaned, if there is suction at the control valve, but no brine is being drawn in.
2. If there is NO suction at the control valve port where you removed the brine line tubing, then the injector should be cleaned.
3. If the injector has been cleaned and there is still no suction check to make sure there is obstruction in the backwash line; that the backwash line does not go up and over the softener more than several feet (which causes pressure loss and the injector not to work correctly); finally check to make sure there is enough pressure. If possible increase your water pressure to softener from your well pump and see if a slightly increased pressure makes the injector work. We recommend a minimum 30 PSI but it does work better if there is 40 to 50 minimum PSI.

System Not Programmed Correctly
In some cases, the 5900-BT control valve may not be programmed correctly. Review the programming instructions earlier in this guide.

Brine Tank Not Filling with Enough Water
Sometimes if the brine tank is not filling adequately, it is possible that the float assembly in the tank is set too low. You would want the float to be several inches above the air check valve inside the tank. This will allow for enough water to be added to the tank before shutting the brine fill cycle. If necessary, pull the float assembly rod up to the appropriate height, and cut the rod at that height, leaving while keeping the rubber washers the adequate space to hold the float in place.

Error Codes

• There are five (5) error codes that could indicate a possible problem with the control valve:
• Error 2 – Homing slot expected. Valve will start looking for home. (Normal operation continues)
• Error 3 – Encoder is not sending a signal (Valve requires service to continue)
• Error 4 – Unable to find homing slot (Valve requires service to continue)
• Error 5 – Motor overload (stalled position or shorted motor) (Valve requires service to continue)
• Error 6 – No Power to Motor (usually this means the cable has come loose)
