Clean Water Systems Pro-Ox 5900-BT-AIR Series Operating and safety instructions

Pro-Ox 5900-BT-AIR Installation & Maintenance Guide
Thank you for purchasing a Clean Water System! With proper installation and a
little routine maintenance your system will be providing iron free water for many
years.
Please review this start-up guide entirely before beginning to install your system
and follow the steps outlined for best results.
The Pro-OX 5900-BT-AIR Iron Filter media must be activated with a 1 cup of un-
scented liquid chlorine bleach when first installing it. Read instructions for more
information. It is easy to do, but a critical step.
The Pro-OX media produces very small particles (fines) when the system is first
installed. Bring the water pressure up VERY slowly during the initial backwash by
opening inlet valve slowly to avoid pushing the media up into the control head.
Performing multiple backwashes at start-up is an important step. It is also
recommended that the air draw or chemical draw functions be disabled during the
start-up period to ensure all the smaller particles have been flushed out.
You should also not bring any other systems online (i.e. softeners, filters, etc.) until
the Pro-Ox system is fully flushed. Depending on the water quality, this may take
several backwashes and a week or two of normal water use.
The Pro-OX media contains dust. Use paper mask and ventilate area to avoid
breathing dust when first pouring the media into the tank.
Minimum 30 PSI required. Maximum pressure 90 PSI.
For indoor installation. Protect from sunlight, rain, and freezing.

What to Do if Your Tank Does Not Sit Level on Floor Out of the Box:
Your black 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 knocking it on a concrete or solid floor once or twice to level it.

How Your Pro Ox 5900-BT-AIR Works
The Pro Ox 5900-BT-AIR, when properly
applied, is an efficient and cost effective system
for the removal of iron and odor.
The Pro Ox 5900-BT-AIR control valve
maintains a compressed “air pocket” in the
filter free space top of the tank while system is
in service. As the water passes through the air
pocket, iron is oxidized. Additionally, dissolved
oxygen is added to the water.
The Pro Ox filter media bed then removes the
iron from the water. The backwash rinse cycle
(usually done at night, every 2-4 days) will
remove accumulated iron and replenish the
filter media bed.
Each night a fresh pocket of air is drawn into
system to allow maximum oxidation.
Note About Aeration
The Pro Ox 5900-BT-AIR utilizes air, oxidation
and filtration for the removal of Iron.
You might notice a bit of tiny air bubbles in the
water during first week or so after installation
and this is normal but goes away after
installation.
Some well waters do not need aeration and this feature can be turned off if applicable. You can
also start the first 2 weeks without aeration and see how it works for your water and turn on
the aeration later quickly and easily.

System Install Steps Overview
1. Put gravel in first, then Pro-OX media, then Turbidex media. Add 1 cup of liquid bleach
non-scented and allow to soak for at least 1 hour, but up to 24 hours is OK.
2. Make the plumbing connections from your existing system to the bypass assembly,
installing extra valves, unions, pressure gauges and hose bibs as needed.
3. Attach the control head to the tank, and to the bypass assembly.
4. Install Drain Line tubing (& external flow control assembly if using model 1.5 or 2.0 CF)
5. Plug in the power supply and program the valve.
6. Follow the instructions to put the system 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 filter system on a dry level spot where it won’t be
exposed to freezing temperatures, direct sunlight, wind or rain.
4. 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.

Pro Ox 5900-BT-AIR Installation & Startup Guide
Page 6www.cleanwaterstore.com Rev. 02-26-2020
Best Practices for Piping & Drain Installation
1. See typical installation (Fig 2). The Pro-OX-AIR filter is installed after the pressure tank.
2. Install on a level floor or surface.
3. Filter system 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. Locate the unit near an unswitched, 120 volt / 60 Hz grounded electrical outlet.
6. Make sure to connect the IN pipe to the 5900-BT inlet and the OUT pipe to the outlet.
7. Make sure there is a working gate or ball valve before the 5900-BT Pro-OX 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 Pro-OX-Air Filter
and before the second ball valve, for rinsing and sampling water.
8. 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.
9. 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 filter on by-pass and
remove the filter system from the piping.
10. 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.
11. 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 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 (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 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.
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.
Add Filter Media 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 filter tank.

Pro Ox 5900-BT-AIR Installation & Startup Guide
Page 9www.cleanwaterstore.com Rev. 02-26-2020
6. Add the filter gravel that came with your order. The gravel should cover the bottom
distributor screen before adding the Pro-OX filter media.
7. Next, add the Pro-OX Filter media, then the Turbidex Media.
8. The tank should be about 2/3 full of media,
do not fill much more than 2/3 full, even if
there is media left over. We ship the correct
amount of media to fill your tank for most
orders.
9. Add 1 cup of household bleach down the
distributor tube and 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. 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.
12. 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.
13. 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.
14. 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. Make sure the drain tubing is firmly clamped to the
barbed fitting with a hose clamp to prevent leaks or blow-offs.

Pro Ox 5900-BT-AIR Installation & Startup Guide
Page 10 www.cleanwaterstore.com Rev. 02-26-2020
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 In and Out service pipe.
Note: There is supposed to be some “play” in the whole assembly. No need to over-tighten.
Electrical Connections
P = Power – Use this connection
B = Optional (not used, powered in backwash step only)
S = Optional (not used, powered in regeneration step only)
Connect the power supply to the control valve connection P. This is the connection on the outside of
the valve, nearest the side or outer section of the valve. Plug into a wall outlet.
B and S connections are used to power optional external relays, pumps, or solenoid valves (not used for
most residential applications).
Install 9V Battery (not included)
DO NOT INSTALL BATTERY UNTIL AFTER INITIAL BACKWASH!
Connect 9V battery to battery cable under control panel. Battery cable and battery will sit under control
panel.
Control panel can be easily removed to access battery cable if needed, no tools are required.
During power failures the battery will maintain the time of day if the battery has power. The display is
turned off to conserve battery power during this time. If a power failure occurs while the system is
regenerating, the motor will advance to a shut-off position to prevent constant flow to drain.

Pro Ox 5900-BT-AIR Installation & Startup Guide
Page 11 www.cleanwaterstore.com Rev. 02-26-2020
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 filter system and also one after as shown in Fig 2. The
pressure gauges are optional but a hose bib is strongly recommended after
the Pro Ox 5900-BT 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 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.

Pro Ox 5900-BT-AIR Installation & Startup Guide
Page 12 www.cleanwaterstore.com Rev. 02-26-2020
External Drain Line Flow Control (“DLFC”)
If you bought a 1.5 or 2.0 cubic foot Pro-OX 5900-BT Filter
you will get an external Drain Line Flow control with your
order. This is made up of three pieces: a 1” x ¾” Adapter,
the DLFC, and two hose barb fittings.
Assemble the 3 parts using Teflon tape, making sure the flow arrow is facing the right
direction. This can go anywhere in the drain line run, even at the end. Clamp it to a wall.

12. To Set the Number of Days between Air-Draw Cycles, Press the Set/Change Button
13. Set to 1 day, to regenerate the system with new air daily (recommended) d - 01
14. During this process, the valve will use a little bit of water to create suction to regenerate
the air and will make some noise during this cycle. However, the valve will still backwash
only on the days that you have programmed it to.
15. To exit menu, press the Menu/Enter button
Program Your Valve: Master Programming Mode
1. Regeneration Time (r)
Press the Menu/Enter Button. To enter Master Programming Mode press and hold both
buttons for 5 seconds. “Regeneration” refers to the backwash/air-draw/rinse cycles.
The next 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 may occur, when required.
We recommend setting system to backwash at 2 AM, or when water will not be used in home.
If you have 2 or more filters, make sure they are programmed to start an hour apart.
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)
2. Regeneration Cycle Step Programming
The next 5 displays viewed are part of series of settings used to program Regeneration Cycle.
Step 1, the air release, is not programmable, and will not be displayed for programming.
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:
For initial start-up, Set the chem draw “J” value to 0 and air-draw (step 4) to 0. See below
After initial backwash and rapid rinse start-up is compete, Set each step according to the
values below

Pro Ox 5900-BT-AIR Installation & Startup Guide
Page 14 www.cleanwaterstore.com Rev. 02-26-2020
16 minutes. Not Programmable. This is the Air Release cycle. [ Not Displayed]
210 minutes. This is the Backwash cycle. [ 2 - 10]

If you “get stuck”, keep pressing the Menu/Enter button until you return to service screen.
Detailed Steps to Starting Up Your Pro-OX 5900-BT-AIR System
1. Dry new Pro-OX filter media has a lot of black fines or dust in it, and must be rinsed free by
backwashing and rinse, which may take several backwashes.
2. MAKE SURE THE SOURCE WATER ENTERS THE INLET PIPING (IN OTHER WORDS, THAT THE
SYSTEM IS PIPED IN CORRECTLY, WITH WATER INLET TO THE INLET ON THE BYPASS VALVE)
3. MAKE SURE THAT BOTH THE INLET AND OUTLET BYPASS VALVES ARE CLOSED INITIALLY

Pro Ox 5900-BT-AIR Installation & Startup Guide
Page 15 www.cleanwaterstore.com Rev. 02-26-2020
4. MAKE SURE TO CLOSE THE BALL VALVE OR GATE VALVE AFTER THE FILTER SO NO WATER
CAN ENTER THE HOME DURING THIS INITIAL BACKWASH.
5. If you have any filters or softeners installed after filter system, put them on by-pass mode.
6. First, if days remaining is not already at 1, press and hold the Set/Change button.
7. Next press and hold the Set/Change button, until the valve begins the backwash cycle and
the display reads 1 [1- 10]. This is the first cycle that starts a backwash.
8. Start to put the valve into the service position by turning the inlet bypass knob counter-
clockwise a little, slowly, until you can hear water passing through the bypass into the filter.
Stop & wait until you see water coming out of the drain line. It will often be mixed with air.
9. 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.
10. After several minutes, you should have the valve fully open, and with no media coming out.
The water will be black, turning to gray, mostly clear water- the water does not get crystal
clear in the Backwash mode (only at the end of Rapid Rinse and during Service).
11. After the backwash cycle, the filter will go into a rest for 5 minutes. After 5 minutes the
next cycle, the Rinse cycle will start.
12. NOTE: To skip to next cycle or fast forward past Rest or other cycles, hold down Set/Change
button for 3 seconds. Let unit do Rapid Rinse cycle & advance to “Service” position.
13. Press and hold the Set/Change button, until the valve begins the backwash cycle and the
display reads 1 [1- 10] and start up another backwash, rest, rinse sequence. You may need
to repeat this process 2 to 4 times to thoroughly clean up the filter media.
14. Next, open the outlet on the bypass valve and then open the hose bib after the system and
allow the water to run until it is clear. Run water in the home 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. Run the water in the home for 5 to 10 minutes to flush pipes.
Congratulations, you are done starting up your filter system!

Using the Optional Chlorine Side Tank System
The chlorine side tank feature allows bleach to be drawn during Air Draw
cycle. In the Legacy View App this is referred to as “Pulse Chlorine Setting”
Chlorine has a very good effect on the Pro-OX media, cleaning and restoring
the Pro-OX. This helps eliminate slime and rust build-up inside the filter
and keeps seals and spacers cleaner. No chlorine is added or enters into
the water that enters the home.
NOTE: Chlorine works a little better than peroxide but if desired the
Pro-OX-BT-AIR can use hydrogen peroxide in place of chlorine bleach.
NOTE: Never mix peroxide and bleach together!
1. See “Regeneration Cycle Step Programming” Page 14 and make sure
J-2 or J-3 is active. J-2 setting means that approximately 8 ounces (1
cup) of chlorine solution will be drawn in. Set to minimum J-2 for but
could be set to J-3 to allow more chlorine solution to be drawn in.
2. Chlorine is only drawn in when the system goes through a
“regeneration” or backwash-rinse cycle not on Air-Only nights.
3. Remove plug on side of 5900-BT valve and attach the 3/8” black tubing from side tank to
the control valve. Make sure to use a back-up wrench on the metal fitting when tightening.
4. Attach other end of tubing to the chlorine side tank.
5. Add 2 Gallons of distilled, softened or bottled water & 1/2 gallon 5%
to 7% non-scented household bleach or (7% hydrogen peroxide) to
side tank. (4 parts water to 1 part bleach or peroxide)
6. Next time Air Charger Pro-OX Filter does a regeneration
chlorine will be drawn in during Air Draw Cycle.
7. Check side tank every 1 -2 months and add additional
chlorine as needed.

Installing and Using the Optional Blue Tooth Legacy View App
For simplified set up and control, please install the Legacy View on a compatible
Bluetooth 4.0+ enabled smart phone or tablet. Note that times and settings EXCEPT
the Air Draw minutes can be set or adjusted. Set the Air Draw minutes on the control
valve, See Page 13 – 14.
1. Download and install the Legacy View app from the Google Play Store, Apple App Store.
2. Open the Legacy View app
3. Choose a valve device at any time from the list of available devices to connect to by clicking
on it (which means your 5900-BT control valve, or valves if you have more than one system)
4. If the valve you want to connect to doesn’t show up, or there is a problem connecting press
the “Scan for Devices” button or the Legacy View logo at any time to refresh the list and start
the process over.
5. If the valve device is a BTLE valve and it has a password other than the default password, the
first time you connect to it the app will ask you to enter the password.
6. After entering it the first time you should not need to enter it again unless it changes.
7. The control valve firmware can be updated by the App. When the app is updated
from the Google Play Store or the Apple App Store, it may contain an updated
firmware program for the valve devices.
8. These updates could contain new features or operational improvements. It is up to
the user to allow these updates to be sent to the valve device. Uploading a new
