Sulfur Air Charge 2510-SXT Installation & Startup Guide
The Air Charger AIO Filter, when properly applied, is an efficient and cost effective
system for the removal of iron and sulfur. The AIO control valve maintains a
compressed “air pocket” in the top of the tank while the system is in service. As the
water passes thru the air pocket, iron and sulfur are oxidized. Additionally, dissolved
oxygen is added to the water. The Air Charger AIO filter media bed then removes the
iron and sulfur from the water.

A daily backwash will remove accumulated iron and replenish the filter media bed.
The regeneration process also adds a fresh air pocket to the system.

Pre-Installation
1. 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 accidentially
drained.
2. 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.
3. Get all of your plumbing parts together before beginning installation. Installation typically takes 3 to 5
hours. However after installation the 2510 SXT Air Charger Filter must be allowed to run through a
complete backwash and rinse cycle.
4. After the system is installed and running, your water may be discolored, or full of sediment or rust,
particularly if this is older or corroded piping. Typically this clears up over a day or two.
Assembly and Installation Instructions
1. The 2510 SXT Air Charger filter is installed after the pressure tank. If you are also installing a water
softener, install the softener after the 2510 SXT Air Charger filter.
2. Make sure to follow to connect the in pipe to the Fleck 2510 SXT inlet and the outlet to the outlet (see
Fig 2). As you face the Fleck 2510 SXT control from the front, the water enters on the right and exits on
the left. From the back (see Fig 2) the water enters on the left. The inlet and outlet are attached to
the bypass valve which is marked with arrows as well.
3. Make sure there is a working gate or ball valve before the Fleck 2510 SXT Air Charger filter and also
one after. Pressure gauges are optional and perhaps not necessary but a hose bib (which is a faucet
that you can attach a garden hose to) is strongly recommended after the 2510 SXT Air Charger filter
before the second ball valve. This makes it easy to rinse your new 2510 SXT Air Charger filter on start-
up and gives you a place to test the water before it enters your household plumbing.
4. If you will be using copper piping, do not sweat the copper pipe directly on to the Fleck 2510 SXT
control valve. Avoid heating up the Fleck 2510 SXT control valve plastic with the torch.
5. You do not need unions to install your Fleck 2510 SXT control. If you need to remove it, the Fleck 2510
SXT has quick-release couplings that make it easy to put the 2510 SXT Air Charger filter on by-pass and
remove the filter system from the piping.
6. 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 Fleck 2510 SXT control and into a drain, it does not
have to drain down, as the filter backwashes under line pressure from your well pump.

7. Insure the brine line check valve with screen is installed on the brine valve (See Fig. 2) This is the AIR
DRAW point of entry.

System Limitations
•The Air Charger Filter utilizes air, oxidation and filtration for the removal of Iron and Sulfur.
This process will leave some air or effervescence in the water. The effervescence may give the
water a milky appearance and is simply excess air in the water. While a certain amount of
effervescence will always be present, it may be most noticeable during the first 30 days.
Media Loading Guide
1. Place the media tank on a level surface in an area with adequate ventilation. Proper
precautions should be taken to cover your eyes, mouth and nose before pouring the media
into the tank.
2. After removing the control valve, center the riser tube in the tank and place the PVC cap on
the riser to prevent media from entering the tube. It is important that the riser tube stays
properly centered in the tank as the media is installed.
3. Attach the plastic diffuser cone to the distributor tube if
it did not come attached (see right). In order to do this,
swab PVC glue on the distributor tube 4 inches below
threads on the tank. The diffuser cone can then be
slipped over the distributor and attached to this
location. See Fig. 1 for an idea of placement.
4. First, add the gravel.
5. Next, add the Centaur Carbon Filter Media to the tank.
After adding the Centaur carbon, the tank should be
approximately 2/3 full of filter media. Do not fill past
2/3rs, even if there is some extra media left over
6. Once the media have been added to the tank, fill the tank with water. It OK to have the
media soaking in water as you finish the installation and plumbing.
7. Carefully thread the backwash control valve to the tank. The riser tube must be properly
centered in the valve and should not be forced as the valve is installed.
8. The check valve that is provided must be installed on the inlet of the unit.
9. Be sure to backwash and rinse the Sulfur Air Charge system thoroughly before using. See
following page.

Bypass Assembly
The system must be backwashed once upon startup. First, put the system into service mode.
Normally the system ships in the bypass position. Once the system is properly plumbed in, make
sure to turn both of the bypass valve knobs 90 degrees into service mode.
Regeneration Cycle (59 minutes)
1. Backwash (14 minutes) During this cycle, the water carrying the iron runs to the drain. Untreated
water is available during regeneration.
2. Air Recharge (40 minutes) during this cycle, the unit empties water to the drain and is recharged
with air. The sound of air being recharged will be heard. Air bubbles should go down to the drain
before proceeding to the next step. Adjust cycle time if necessary.
3. Rapid Rinse (5 minutes) During this cycle, water enters the tank, compressing the air into a pocket
at the top of the tank.
4. Brine Refill (Off)
5. Unit Returns to the In-Service Position
The frequency and time of regeneration can be changed due to the following reasons.
• In conditions of high water usage and/or high levels of iron, the unit may need to regenerate more
frequently than once every three days. The unit can be set for daily regeneration or to regenerate
every two days. DO NOT set the regeneration frequency for a longer period than 3 days, as the
filter medium can become fouled with iron, rendering the unit ineffective.

How To Remove Media From Control Head
Sometimes, when doing the Initial Backwash, the media gets lifted up into the control head. You can tell this
happened because you will have little or no flow, either going out to drain while in the backwash positon, or
when in the service positon.
To remove media from a control head, do the following:
1) Put the Inlet Bypass in the Closed position.
2) From the Service Mode, initiate a manual regeneration, by pressing and holding the regen button (button
on far left).
3) The valve will advance to the BW (backwash) position, and start counting down. Press the Regen button
again, and wait for the valve to advance and stop at the Rapid Rinse (RR) position.
4) With the valve in the RR position, open and close the Inlet Bypass valve several times. After the third or
fourth time, leave it in the open position and check the drain line- do you have a good solid flow? 90% of the
time, the answer is yes, but sometimes, even after opening and closing the valve many times, you still don’t
have good flow… But, in either case (good or no flow), continue…
5) With the Inlet Valve OFF, Advance the valve back to Service position again, and again press and hold the
Regen button, we are putting the valve back to the Backwash position.
6) Open the Inlet valve just enough so you can hear the water passing thru the valve- you should notice a
corresponding slow flow out of the drain line. After a minute, if there are no air bubbles present, open the
valve about another quarter inch- again, you should see a corresponding increase in the flow… And you will
continue until the valve is full open.
IMPORTANT:
Any time that you are in the Backwash or Rapid Rinse position, you may need to unplug the power- this will
hold the valve in its current position, so it doesn’t ‘time out’ and go to the next position. When you plug the
valve back in, after a minute it will return to where it was when you unplugged it (i.e. 2:32 remaining in BW).
Understand, it is not possible to jam media into the head while in Rapid Rinse, or Service, just in the Backwash,
when the flow direction is reversed.
What you are trying to accomplish, after you have pushed the media back in to the tank in the Rapid Rinse
position, is to get the Inlet valve all the way open in the Backwash position, without it jamming media back in
the head, and this is the part where you have to go slow, open up the Inlet valve a little bit at a time and let it
run for a few minutes- this is why you may have to unplug it- and then, once you have done that, finally, do
one more backwash, starting with the Inlet valve open, just as it will be when it does it automatically at night.
Once it does that successfully, you are done.
