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

How Your Air Charger Sulfur
Filter 5900BT-AIR Works
The Air Charger Sulfur Filter 5900BT-AIR, when
properly applied, is an ecient and cost eective
system for the removal of sulfur odors.
The Air Charger Sulfur Filter 5900BT-AIR control valve
maintains a compressed “air pocket” in the top of the
tank while the system is in service.
As the water passes through the air pocket, the sulfur
is oxidized. Additionally, dissolved oxygen is added to
the water.
The Air Charger Sulfur Filter lter media bed then
removes the sulfur and odors from the water.
Backwash is done by default at 2am (programmable)
1 to 7 times per week depending on the sulfur odors.
This will remove the now elemental sulfur and, if
present, light levels of iron as well.
The Air Charger Sulfur Filter 5900BT-AIR utilizes
air, oxidation and ltration for the removal of
sulfur odors. This process will leave some air or
eervescence in the water. The eervescence may
give the water a milky appearance and is simply
excess air in the water. While a certain amount of
eervescence will always be present, it may be most
noticeable during the rst 30 days after installation of
the system.

System Installation Steps Overview
1. Put gravel in rst, then carbon. If you ordered the optional KDF cubes those go in last, just
add on top of the carbon media.
2. Fill tank with clean water. Allow to soak for at least 1 hour, but up to 24 hours is OK.
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 and Drain Line Tubing Flow Control button (Internal for models
2.0 CF and less, or External ow control assembly for models 2.5 CF and greater)
6. Plug in the power supply and program the valve.
7. 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 o the water to the house and you have an electric water
heater, shut o the power to the water heater before beginning installation.
3. Pick a suitable location for your lter 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.

Best Practices for Piping & Drain Installation
1. See typical installation (Fig 2). The Air Charger Sulfur lter is installed after pressure tank.
2. Install on a level oor 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. 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.
7. DO NOT install the unit in an area of direct sunlight or expose to freezing.
8. Locate the unit near an unswitched, 120 volt / 60 Hz grounded electrical outlet.
9. Make sure to connect the IN pipe to the 5900-BT inlet and the OUT pipe to the outlet.
10.Make sure there is a working gate or ball valve before the 5900-BT Sulfur 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 Sulfur Filter and
before the second ball valve, for rinsing and sampling water.
11.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.
12.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 lter on by-pass and remove
the lter system from the piping.
13.The drain line tubing is connected to a drain from the drain outlet using exible poly tubing.
The drain can run up above the control head and out to a drain, although this may require
installing a one way, apper-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 System into Copper
or Metal Piping Systems
If your new lter 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 orpotential
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 the Carbon Filter Media and Install 5900-BT
Backwash Valve on Tank
1. Make sure you “test t” distributor tube, nd 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 that no gravel or media will
go down distributor tube when adding media.
4. Leave a folded tab of tape so you can easily pull o tape after
lling 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 lter tank.

www.cleanwaterstore.com 10
Air Sulfur Filter 5900BT-AIR Installation & Maintenance Guide
Rev-010423
6. Add the lter gravel that came with your order. The gravel should cover the bottom
distributor screen before adding the carbon lter media.
7. Next, add the lter media.
8. The tank should be about 2/3 full of media, do not ll much more than 2/3 full, even if there
is media left over. We ship the correct amount of media to ll your tank for most orders.
9. Fill tank completely with water and 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 a small amount of silicone grease to both O-rings (only O-rings,
not tank thread) on the bottom of the control valve and screw on 5900BT control
valve carefully.
13.Do not lubricate tank threads or any other ttings other than O-rings. Do not use
pipe-joint compound, vegetable oil, Teon tape, or Vaseline or other petroleum 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 exible tubing. If you use hard
PVC piping for the drain line, you must able to remove the hard drain piping and attach
exible tubing for testing purposes.
16.Make sure the drain tubing is rmly clamped to the barbed tting with a hose clamp to
prevent leaks or blow-os.

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 ttings 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.
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 o to conserve battery power during this time. If a power failure
occurs while the system is regenerating, the motor will advance to a shut-o position to prevent
constant ow to drain.
Piping Installation
1. Using Teon 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.
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 lter 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.

www.cleanwaterstore.com 13
Air Sulfur Filter 5900BT-AIR Installation & Maintenance Guide
Rev-010423
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
lter system from the piping.
6. The drain line tubing is connected to a drain from drain
outlet using exible 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.
External Drain Line Flow
Control (“DLFC”)
If you bought a 2.5 cubic foot 5900-BT
Sulfur 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 ttings.
Assemble the 3 parts using Teon tape, making sure the ow arrow is facing the right direction.
This can go anywhere in the drain line run, even at the end. Clamp it to a wall.
Program Your Valve: Main Menu
1. Enter main menu, by pressing the Menu/Enter button (Time of day will ash)
2. Set time of day by pressing the Set/Change button (First digit will begin to ash)

11.To Set the Number of Days between Air-Draw Cycles, Press the Set/Change Button
12.Set to 1 day, to regenerate the system with new air daily (recommended).
13.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.
14.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 identied by the letter ‘r’
in the left digit. Set the desired time of day that a regeneration may 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 lters, make sure they are programmed to start an hour apart, so they do
not backwash at the same time.
The rst 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 4 displays viewed are part of a series of option settings used to program the
Regeneration Cycle.
Step 1, the air release, is not programmable, and will not be displayed for programming. The
actual step takes approximately 4 ½ minutes.

www.cleanwaterstore.com 15
Air Sulfur Filter 5900BT-AIR Installation & Maintenance Guide
Rev-010423
Each display is used to set the duration time in minutes for that specic 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
Step 1 Not Programmable. This is the Air Release cycle. (If using the Legacy app, displays 1 min.)
Step 2 10 minutes. This is the Backwash cycle. [ 2 - 10]
Step 3 5 minutes. This is a rest cycle. [ 3 - 05]
Step 4 20 minutes. This is the air-draw cycle. [ 4 - 20]
Step 5 6 minutes. This is the Rapid Rinse cycle [ 5 – 06]
Hydrogen Peroxide Draw Feature: Pressing the menu/enter button again will display the “J”
value setting. Set this parameter to 00 if you do not plan to use Peroxide draw feature. The
setting number equates to the number of pulses per the 20-minute period. Total chemical
draw per cycle is approximately: setting #1=4-8oz. #2=8-12oz. #3=12-14oz. and #4=14-16oz. We
recommend this setting be between 2-4 pulses for typical applications.
Pressing the menu/enter button again displays: “bE 1”. Setting this to -00 disables blue tooth and
-01 enables blue tooth setting for using the Legacy View App.
Pressing the menu/enter button again displays: bTPP and then changes to 1234. This is used for
setting password protection.
Press the menu/enter button, and now you are back to the home service screen (displaying the
clock time and the number of days until backwash).
See Historical Data and Real Time Flow Rate
Pressing and holding the Menu/Enter button will also access some options:
Flo - This is the ow rate, if water is running, it will display the volume, in gallons per minute.
Gt r - This the total # of gallons that has gone through the lter.
g tot - This is the same as the previous.
rC r - Number of regeneration done. rC- the same.
gPdL - Shows how many gallons used each day.
Gbrl - This is the gallons used between regenerations.
PfDL - This shows the peak, or highest ow rate that has passed through lter in last 24 hours.
If you “get stuck”, keep pressing the Menu/Enter button until you return to service screen.

Detailed Steps to Starting Up Sulfur Air Filter System
1. New activated carbon lter media has a lot of black carbon nes or dust, 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
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. (If you did not install a hose bib and gate
or ball valve after the system as recommended, be sure to NOT use any water in the home
during the initial start-up.)
5. If you have any lters or softeners installed after the lter system, bypass them until all
media nes have been rinsed.
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 rst 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 lter.
Stop and wait until you see water coming out of the drain line. It will often be mixed with
air bubbles.
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 ow out of the
drain line as you increase the ow of water into the lter.
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 lter will go into a rest for 5 minutes. After 5 minutes the next
cycle, the Rinse cycle will start.
12.NOTE: To skip to the next cycle or fast forward past Rest or other cycles, hold down Set/
Change button for 3 seconds.
13.Let the unit do the Rapid Rinse cycle and advance to the “Service” position.
14.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 lter media.

15.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 xture 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 ush pipes.
