What to Do if Your Tank is Not Level Out of the Box:
Your black Tannin 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 Tannin Filter Works
In the Tannin Filter, water enters
the top of the tank and flows
down through the media and up
the distributor tube. Tannin
color is removed by the resin
beads in the Tannin Filter.
During regeneration the first
cycle in the process backwashes
and cleans the Tannin 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 resin
for 1 hour, allowing the color in
the water to be removed.
This entire automatic process,
called ‘regeneration’ takes
about 90 minutes.
Typically the Tannin 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.

Tannin Filter Installation Steps Overview
1. Verify that you have received all parts and there are no damaged or missing parts.
2. If your size Tannin 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 Tannin 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 Tannin 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.

5900-BT Tannin Filter Installation & Maintenance Guide
Page 6www.cleanwaterstore.com Rev 071218
Best Practices for Piping & Drain Installation
1. See typical installation Page 7. If on well water, Tannin Filter is installed after pressure tank.
2. Install on a level floor or surface.
3. Your new Tannin 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. Tannin 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 Tannin 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 Tannin
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 Tannin Filter on by‐pass
and remove the 5900‐BT Tannin 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)

Installation of Your Tannin Filter into Copper or Metal Piping Systems
If your new Tannin 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 Tannin 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 Tannin Filter tank.

5900-BT Tannin Filter Installation & Maintenance Guide
Page 9www.cleanwaterstore.com Rev 071218
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 Tannin
resin.
7. Next add the Tannin 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.

5900-BT Tannin Filter Installation & Maintenance Guide
Page 10 www.cleanwaterstore.com Rev 071218
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.

5900-BT Tannin Filter Installation & Maintenance Guide
Page 11 www.cleanwaterstore.com Rev 071218
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 water Tannin Filter. 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 Tannin
Filter system 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 ferrell attached to
prevent leaking.

5900-BT Tannin Filter Installation & Maintenance Guide
Page 12 www.cleanwaterstore.com Rev 071218
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 non‐threaded 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
Tannin 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.

Master Programming Mode
To enter Master Programming Mode press and hold both buttons for 5 seconds. To change a
value, Press the Set/Change button. When done, press Menu/Enter button to go to next step.
1. Regeneration Time (r)
The first master programming display viewed is the option setting for Regeneration Time. It is
identified by the letter ‘r’ in the left digit. Set the desired time of day that a regeneration (the
backwash and rinse cycles) will occur, when required.
We recommend setting the system to backwash at 2 AM, or at any time that it is unlikely that
any water will be used. If you have 2 or more filters, make sure they are programmed to start
an hour apart, so they do not backwash at the same time.
The first digit(s) indicates the Hour and the other digit indicates A.M. or P.M.
Example: 12 A.M. regeneration time ‐ [ r 12A] (factory setting)
With all digits flashing press the Menu Button to set A.M. or P.M. Once A.M./P.M. is accepted
the next menu item will flash.
2. Regeneration Cycle Step Programming Times
The next 4 displays viewed are part of a series of settings used to program minutes for
Regeneration Cycle which is where filter backwashes tannin resin, draws in brine, rinses media
of any brine remaining after brine cycle, and then refills brine tank with water to make more
brine for the next regeneration.
Set each step according to the values below, appropriate for a Tannin Filter:
110 minutes. This is the Backwash cycle. [ 1 - 10 ]
260 minutes. This is the Brine Draw cycle. [ 2 - 60 ]
38 minutes. This is the Rapid Rinse cycle. [ 3 - 6 ]
4Brine Refill Cycle: set the time according to the Cubic Foot size of your system
below:
0.5 CF: [ 4 – 4]. 1.0 CF: [ 4 – 6]. 1.5 CF: [ 4 – 9]. 2.0 CF: [ 4 – 12]. 2.5 CF: [ 4 - 15].

Gbrl‐ is the gallons used between regenerations.
PfDL‐ This shows peak, or highest flow rate that has passed through the filter in last 24 hours.
To exit keep pressing Menu/Enter button until you have returned to the service screen.
Start Up Your Tannin Filter
1Close 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 – 10.
2Start to put the valve into the service position by turning inlet the bypass knob counter‐
clockwise about a quarter inch, until you can hear water passing through the bypass into
the Tannin Filter. Wait until you see water coming out of drain line.
3Keep 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
Tannin Filter. After several minutes, you should have valve fully open.
4Cycle 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 Tannin Filter, it will do a slow rinse for the rest of the cycle.
5Allow the valve to finish running through the last two cycles: Rapid Rinse and Brine Refill.
6Open outlet on the bypass valve and then open nearest treated water faucet to filter and
allow the water to run until clear. We advise using a bathtub, laundry sink, or other fixture
that does not have aerator screen as any remaining residue may get caught in the screen.
Congratulations, you are done starting up your water Tannin Filter!

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 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 it gets low, refill to top with water
Tannin Filter salt (pellets or coarse, but any good quality water Tannin Filter salt works fine).
How the Battery Back-up Works
Optional. Uses a 9‐volt battery, not included. Do not install or attach battery until after start‐
up. 9‐volt battery lead wires are found by removing the cover. The battery back‐up maintains
time of day during power failures. Replace battery annually. The battery back‐up continues to
count down gallons remaining during power failure (Metered Version). Menus cannot be
accessed during power failure. During power failure to conserve battery power the display is
turned off.
How to Start an Extra Regeneration Cycle
