2. Pre-Installation
1. Review packing list and make sure you have received all of the parts
listed
2. Shut off power to your house and electric water heater if you have one
3. Pick a suitable location on a dry, level spot that won’t be exposed to
freezing temperatures. A minimum of 20 PSI is required; maximum: 90
PSI
4. Gather all of your plumbing parts. Installation will take about 3-5 hours,
plus the time it takes to run a complete backwash and rinse cycle.
5. Don’t fret if your water is initially discolored or rusty after installation

3. Installation
1. Your 2510 SXT Air Charger Iron
Filter should be installed after
your pressure tank. If you are
also installing a water softener,
install the softener after the
iron filter.

4. Installation
2. Make sure to connect the IN
pipe to the Fleck 2510-SXT
inlet and the OUT pipe to the
outlet (see Fig. 2). The inlet
and outlet are attached to the
bypass valve and marked with
arrows. When facing the
Fleck 2510-SXT from the
front, water will enter on the
right and exit on the left.

3. Make sure there is a working gate
or ball valve after the Fleck 2510SXT Air Charger filter, and also one
after. Pressure gauges are optional
and perhaps not necessary, but a
hose bib (a faucet to which you
can attach a garden hose) is
strongly recommended after the
2510-SXT Air Charger filter but
before the second ball valve. This
makes it easy to rinse your new
filter on start-up and gives you a
place to test your water before it
enters your household plumbing.

6. Installation
4. If you will be using copper piping, do not sweat the copper pipe
directly on to the Fleck 2510-SXT control valve, and avoid heating
the valve’s plastic with your torch.

7. Installation
5. You do not need unions to install your Fleck 2510-SXT control valve.
If you need to remove it, the Fleck 2510-SXT has quick-release
couplings that make it easy to put the air charger filter on bypass
and remove it from your piping.

8. Installation
6. The drain line tubing (not
supplied) is connected to a
drain from the drain outlet
(Fig. 2) using flexible ½” ID
tubing. Note that the drain
line can run up above the
Fleck 2510-SXT control valve
and into a drain – it does not
have to drain down, as the
filter backwashes under line
pressure from your well pump.

7. Ensure the brine line check
valve with screen is installed on
the brine valve (Fig. 3). This is
the air draw point of entry.

10. Installation
8. You should have a small plastic distributor
cone – place it on top of the distributor
tube to help with oxidation as water
passes through the air pocket.

11. Media Loading
1. Place the tank on a level surface in a well-ventilated area. Take
proper precautions to cover your eyes, mouth, and nose before
pouring media into the tank.
http://www.cleanwaterstore.com
12. Media Loading
2. Remove the control valve,
center the riser tube inside the
tank, and place the PVC cap
atop the tube to prevent media
from entering. It is important
that the riser tube stays
properly centered in the tank as
you install the media.

13. Media Loading
3. Attach the plastic diffuser cone to the
distributor tube by swabbing PVC glue
onto the tube about 4 inches below the
tank threads and slipping the cone over
the tube.

14. Media Loading
4. Add the medium sized gravel first, then the fine gravel. Once the
first three media layers have been added, add the box marked
MangOX to the tank until it is about 2/3 full.
http://www.cleanwaterstore.com
15. Media Loading
5. Fill the tank with water, add 2 cups of household bleach, and shake
the tank gently to mix. Alternatively, you can add bleach to a 5
gallon bucket and fill the tank with the water and bleach mixture.
Either way, allow it to soak in the tank for a minimum of 1 hour.
http://www.cleanwaterstore.com
16. Media Loading
6. Once you’ve added the media, carefully screw the valve on to the
tank. The riser tube must be properly centered in the valve and
should not be forced as the valve is installed. The check valve that
is provided must be installed on the inlet of the unit (Fig. 2).

17. Regeneration Cycle
1. Now you must run a complete regeneration cycle before beginning
operation if your system. First, put the system into service mode by
turning both bypass valve knobs 90 degrees (assuming it was
shipped in bypass position, as it usually is).
http://www.cleanwaterstore.com
18. Regeneration Cycle
2. The first part of this cycle is the backwash cycle. It will run for 14
minutes, during which iron-heavy water will be drained. Untreated
water will be available during regeneration.
http://www.cleanwaterstore.com
19. Regeneration Cycle
3. Next is the air recharge cycle, which runs for 40 minutes, empties
water in the tank to the drain, and recharges the air pocket inside.
Air bubbles should be drained before proceeding to the next step.
Adjust cycle time if necessary.
http://www.cleanwaterstore.com
20. Regeneration Cycle
4. Next is the rapid rinse cycle, which runs for 5 minutes and
compresses the air inside the tank into a pocket at the top.
http://www.cleanwaterstore.com
21. Regeneration Cycle
5. The next cycle would be the brine refill cycle, if you were using your
2510-SXT valve as a softener. Since you have an iron filter, disregard
this step.
Note: In conditions of high water usage and/or high levels of iron, the unit may
need to regeneration more frequently than once every three days. The unit can
be set for daily regeneration, or for regeneration every 2 days. Do not set the
regeneration frequency to a period longer than 3 days, as the filter media will
become fouled and ineffective.
http://www.cleanwaterstore.com
22. Regeneration Cycle
6. The unit, having skipped the brine refill cycle, should now return to
the in-service position.
http://www.cleanwaterstore.com
23. System Limitations
The Air Charger Filter utilizes air, oxidation and filtration for the
removal of Iron and Iron. 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 after installation of the system.
