Pre-Installation
1. Review your packing list and make sure you have received all the parts before beginning installation.
Please ensure that all parts are included before scheduling a plumber or installer to come to the site.
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 in case water heater is accidentally
drained.
3. Pick a suitable location for your filter system on a dry level spot where it won’t be exposed to freezing
temperatures. A minimum of 20 PSI is required. Maximum pressure is 90 PSI.
4. Get all of your plumbing parts together before beginning installation. Installation typically takes 3 to
5 hours. However after installation the Tannin filter must be allowed to run through a complete
backwash and rinse cycle (also called ‘regeneration’). You don’t have to be present for this first
backwash necessarily, but it does take 90 minutes.
5. After the system is installed and running, your water may be discolored, or full of sediment/rust,
particularly if this is older piping that has been exposed to iron or manganese for some time.
Typically this clears up over a day or two, but can persist for weeks if the pipe is old galvanized iron
pipe that is corroded.
Best Practices for Piping & Drain Installation
1. See typical installation (see Fig 2). The Tannin filter is installed after the pressure tank.
2. Make sure the water is soft going into the Tannin filter as hardwater will ruin the Tannin resin.
3. Make sure to connect the IN pipe to the 5900e inlet and the OUT to the outlet (see Fig 3). As you face
the 5900e control from the front, the water enters on the right and exits on the left. From the back
(see Fig 3) the water enters on the left and exits on the right. The inlet and outlet are attached to the
bypass valve which is marked with arrows as well.
4. Make sure there is a working gate or ball valve before the 5900e Tannin filter and also one after as
shown in the diagram (Fig 2). The pressure gauges are optional but a hose bib (a faucet that you can
attach a garden hose to) is strongly recommended after the Tannin filter and before the second ball
valve. This makes it easy to rinse your new Tannin filter on start-up and gives you a place to test the
water before it enters your household plumbing.
5. If you will be using copper piping, do not sweat the copper pipe directly on to the 5900e control
valve. Avoid heating up the 5900e control valve plastic with the torch.
6. You do not need unions to install your 5900e control. If you need to remove it, the 5900e has quick-
release couplings that make it easy to put the Tannin filter on by-pass and remove the filter system
from the piping.

Tannin 5900e Installation & Startup Guide
Page 5 www.cleanwaterstore.com Rev 062915
7. The drain line tubing (not supplied) is connected to a drain from the drain outlet using flexible ½” ID
tubing. Note that the drain can run up above the 5900e control and into a drain, it does not have to
drain down, as the filter backwashes under line pressure from your well pump. 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.
Installation of Your System into Copper or Metal Piping Systems
If your new filter system is to be installed in a metal (conductive) plumbing system, i.e. copper or
galvanized steel pipe, the plastic components of the system 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 the 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.
Consequently, 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.
This is simple and easy step to take if you are installing your water treatment system into copper
piping. A simple ground jumper wire with a pipe clamp can be purchased at any Home Center, or
hardware store etc for a few dollars.

How Your Tannin Filter Works
See Fig 1. In the Tannin filter, water enters the top of the tank and flows down through the media and up the
distributor tube. Tannins are drawn to the resin beads in the Tannin filter. During backwash, the water flow
is reversed and water flows down the distributor tube and up through the media, lifting and expanding the
tannin 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 tannin resin for 1 hour, allowing the tannins to be
swapped out with harmless sodium or potassium ions. This entire automatic process, called ‘regeneration’
takes about 90 minutes. Typically the Tannin filter is set to regenerate every 14-21 days, during the middle of
the night when no water is being used.

Installation Instructions
1. Wrap the top of distributor tube with electrical or duct tape so that no gravel or Tannin resin will go
down the distributor tube when adding the media.
2. First add the gravel provided before adding resin.
3. Next add the Tannin resin using the media funnel provided. The tank will be approximately 2/3 full,
however do not fill it past 2/3 full, even if there is some extra left over.
4. Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube when
removing cap or tape.
5. Attach plastic top screen to the under-side of the 5900e 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.
6. Add a small amount of silicone grease to the tank threads and screw on 5900e control valve carefully.
Do not use pipe-joint compound, vegetable oil, Teflon tape, or Vaseline or other petroleum greases to
lubricate tank threads.
Plug or tape top of distributor tube
when adding media to prevent media
from entering. Remove when
finished.

7. Insert the bypass assembly if it has not been pre-assembled. See the bypass image below. Note the
pipe connectors, while the other end is what gets attached to the control valve. The 5900e valve is
usually shipped in by-pass position. Leave in bypass position for now.
5900e Bypass and Service Mode Positions
8. Lubricate the by-pass valve o-rings on the pipe connectors only with silicone grease and connect the
bypass assembly to the 5900e control by sliding the bypass valve firmly into the body of the 5900e.
DO NOT USE VEGETABLE OIL OR PETROLEUM GREASE ON ANY PART OF THE 5900e CONTROL VALVE.
O-rings are OK to lubricate but not the main tank threads.
9. Next lubricate the end-connectors with some silicone grease and insert them into the bypass valve.
10. Note that the 5900e is usually shipped in the bypass position. There is a bypass valve knob on both
the inlet and the outlet (Fig 3). You can easily tell if it is in bypass because the two knobs will be in
line with each other (Fig 5). If the valve is in the Service position (Fig 5) the knobs will be parallel to
each other. Make sure both sides are in the by-pass position.
11. Now install your water pipes to the 5900e bypass end connectors. Make sure inlet is installed to the
'In" pipe connector on the bypass valve and outlet is on the “Out” connector.
12. Connect some flexible tubing from the drain connection on the 5900e control valve to a suitable drain
such as a septic tank or drain to a sewer. It is OK to run the drain line up and over the Tannin filter,
up to 4 feet above the top of the tank. If the drain line will be more than 20 feet, and especially if
your system is a 2.0 or 2.5 cubic foot size, use larger diameter tubing such as ¾” or 1”. Note that it is
desirable to be able to run the drain line into a bucket in order to test the backwash flow rate in the
future. This is why hard piping the drain line is discouraged, however, if you do use hard PVC piping
for the drain line, and you are able to remove the hard PVC drain piping and attach flexible tubing

Tannin 5900e Installation & Startup Guide
Page 11 www.cleanwaterstore.com Rev 062915
should you ever desire for testing purposes, it is OK to use rigid PVC pipe for the drain. Make sure the
drain tubing is firmly clamped to the barbed fitting with a hose clamp to prevent leaks.
13. Next, connect the solution tank to the 5900e control valve with the black tubing, provided with the
brine tank.
Attaching the brine line tubing to the brine tank & the 5900e brine valve
14. Insert 3/8” diameter tubing into the brine tank connection. Screw the nut with the sleeve and Ferrell
attached to prevent leaking.
Fig 8 5900e Brine Line Installation
15. 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. Next, slide the black (or clear)
compression ring on to the tubing with the narrower diameter going on first. Then slide the taller,
white compression ring on to the tubing with the wider diameter going on first. The two compression
rings should lay flush against each other on the tubing. Slide them in to the brine injector nut and
place the brine tubing into the brine valve. Finally, push the brine injector nut, which now has the
compression rings inside of it, on to the threading of the brine valve and rotate the nut clockwise,
screwing it on to the brine valve. Tighten it down to finger tightness. The tubing should be firmly
attached and not slide out if pulled on.

Tannin 5900e Installation & Startup Guide
Page 12 www.cleanwaterstore.com Rev 062915
16. Add approximately 5 gallons of water to the brine tank, and then fill the brine tank with salt, using
about 300 lbs, or 6 50-lb bags. It is OK to use any kind of water softening salt, however we find that
extra coarse salt works better than pellets. You do not have to add water to the brine tank again
after this first time during the start-up.
17. See the over-flow barbed fitting on the side of the brine tank. You do not have to connect this to a
drain. 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.
18. Now you are ready to turn on the water to the system. Turn on the water and leave on bypass and
check for leaks. Leave the ball valve after the Tannin filter closed, so water is still off to the house,
but connect a garden hose and open up the hose bib after the Tannin filter and allow the water to
run. This will help to clear out any foreign material that may be in the pipes from the piping
installation. If you do not have a valve installed after the Tannin filter and you do not have a hose bib,
you will need to turn the water on inside the house to let the water run. Use a bathtub or laundry sink
or other fixture that does not have an aerator screen.
19. Leave the water running out of the garden hose at a slow rate. Now you can turn the bypass valve to
the service position. First open the Inlet Side of the bypass valve. Second slowly open the Outlet Side
of the bypass until it is in the full service position. Make sure you are turning the bypass valve knobs
in the correct direction which is counter-clockwise as you face the bypass valve knobs.
20. Now turn on the garden hose to full force and let the water until it turns relatively clear. The water
may have some color at first.
21. Next, you will need to program the system to work as a Tannin filter. There are a few settings that
must be changed before the system can be put into service. Plug in the control valve and continue on
to the next page to begin the programming instructions.

Example: 2 A.M. regeneration time - [ r 2A ] (factory setting)
3. Regeneration Cycle Step Programming (1)(2)(3)(4)
The next 4 displays viewed are part of a series of option settings used to program the
Regeneration Cycle. Up to 4 steps can be programmed, however, some steps may not be
necessary for your application and will be set to 0. Each display is used to set the duration
time in minutes for that specific step in a regeneration cycle. A step # will turn on for the
regeneration cycle step being programmed. Regeneration steps are skipped by setting the
display to 0 as shown below:
Examples: Regeneration Cycle Step #1 - 10 minutes - [ 1 - 10 ] (Factory Setting)
Regeneration Cycle Step #2 - skipped - [ 2 - - 0 ]
Set each step according to the values below, appropriate for a Tannin filter:
18 minutes. This is the Backwash cycle. [ 1 - 8 ]
260 minutes. This is the Brine Draw cycle. [ 2 - 60 ]
36 minutes. This is the Rapid Rinse cycle. [ 3 - 6 ]
4For the Brine Refill Cycle, set the time according to the size of your system below:
1.0 C.F. - Set to 12 min;
1.5 C.F. - Set to 18 min;
2.0 C.F. - Set to 24 min;
2.5 C.F. - Set to 30 min. Example: [ 4 - 12 ]

Initial Backwash
1If 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. Now, proceed to step two.
2Start to put the valve into the service position by turning inlet the bypass knobs counter-
clockwise about a quarter inch, until you can hear water passing through the bypass into the
filter. Stop and wait until you see water coming out of the drain line. It will often be mixed with
air bubbles, but we will want to get all of that air out. 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 a corresponding increase in flow out of the drain line as you increase the flow of water into
the filter. After several minutes, you should have the valve fully open, and with no media
coming out. The water may appear milky white.
3If possible verify that the backwash flow corresponds with the size of your system below. You
can easily run the drain hose to a bucket and using a watch verify the flow rate in gallons per
minute. An adequate backwash is critical to properly clean the Tannin resin and prevent it from
cementing together.

4Once the water is clear, press and hold the Set/Change button, and after 3 seconds the valve will
start to advance to the “Rinse” position. Once again, allow the water to flow for about five
minutes or until the water is clear.
5Press and hold the Set/Change button advance to the “Service” position. Next, open the 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.
Congratulations, you are done setting up your valve!

More Troubleshooting Tips
Brine Solution Not Being Sucked In During Regeneration
Most problems occur when the 5900e is not drawing in the brine. Make sure the injector is drawing in the
brine:
1. Remove the brine tank tubing where it enters the 5900e control valve.
2. Initiate a backwash and skip to the Brine Cycle by following the steps below:
A. Starting 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
B. 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.
C. 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, which is the Brine Cycle,
where it is supposed to suck in the brine solution.
3. If it is sucking strongly, check the brine tank float inside the brine well and make sure there are no
rubber bands around it, and 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.
4. If there is NO suction at the control valve port where you removed the brine line tubing, then the
injector should be cleaned.
5. 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 Tannin filter 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 the Tannin filter 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 Backwashing Adequately
The other main problem that may occur is if you do not have enough backwash flow rate to properly clean
the Tannin filter. You can verify the backwash flow rate by running the drain line into a bucket and timing it
when the 5900 is in Cycle 1 or backwash. A 1.0 or 1.5 cubic foot system should have 2.0 gallons per minute
and a 2.5 cubic foot system should have 4.0 gallons per minute of backwash.
