Pre-Installaon
Review your packing list and make sure you have received all the parts before beginning installaon.
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 installaon in case water heater is accidentally drained.
Pick a suitable locaon for your lter 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.
Get all of your plumbing parts together before beginning installaon. Installaon typically takes 3 to 5
hours. However aer installaon the Pro-OX Filter must be allowed to run through a complete backwash
and rinse cycle.
Aer the system is installed and running, your water may be discolored, or full of sediment or rust, parc‐
ularly if this is older or corroded piping. Typically this clears up over a day or two.
Best Pracces for Piping & Drain Installaon
See typical installaon (see Fig. 2 on page 6). The Pro-OX lter is installed aer the pressure tank.
Make sure to follow to connect the in pipe to the Fleck 2510 inlet and the outlet to the outlet (see Fig. 2).
As you face the Fleck 2510 control from the front, the water enters on the right and exits on the le. From
the back (see Fig. 2) the water enters on the le. The inlet and outlet are aached to the bypass valve
which is marked with arrows as well.
Make sure there is a working gate or ball valve before the Fleck 2510 Pro-OX lter and also one aer as
shown in the diagram Fig. 2. The pressure gauges are oponal and perhaps not necessary but a hose bib
(which is a faucet that you can aach a garden hose to) is strongly recommended aer the Pro-OX lter
before the second ball valve. This makes it easy to rinse your new Pro-OX lter on start-up and gives you a
place to test the water before it enters your household plumbing.
If you will be using copper piping, do not sweat the copper pipe directly on to the Fleck 2510 control valve.
Avoid heang up the Fleck 2510 control valve plasc with the torch.
You do not need unions to install your Fleck 2510 control. If you need to remove it, the Fleck 2510 has
quick-release couplings that make it easy to put the Pro-OX lter on by-pass and remove the lter system
from the piping.
The drain line tubing (not supplied) is connected to a drain from the drain outlet using exible ½” ID tub‐
ing. Note that the drain can run up above the Fleck 2510 control and into a drain, it does not have to
drain down, as the lter backwashes under line pressure from your well pump. Most plumbing codes re‐
quire an air-gap connecon, so that if your sewer or sepc tank backs up, it cannot cross connect with the
drain tubing.

How Your Pro-OX Iron Filter Works
See Fig. 1. Water enters the top of the lter tank and ows down through the media and up the distribu‐
tor tube. During backwash, the water ow is reversed and water ows down the distributor tube and up
through the media, liing and expanding the Pro-OX media and washing out rust and sediment to drain.
During the backwash the Pro-OX is cleaned by the acon of the water owing through it, so untreated well
water can be used for backwashing. As a nal cycle, the Pro-OX is rinsed to drain by water owing down
through the media, up the distributor tube and to the drain.

Assembly and Installaon Instrucons
1. Unscrew by hand the enre Fleck 2510 control valve from top of tank if it was shipped screwed on.
Place distributor tube in tank if not already inside tank. If not already done, make sure blue cap is on
top of distributor tube, or wrap the top of distributor tube with electrical or duct tape. You do not
want gravel or Pro-OX media to go down the distributor tube.
2. Add lter gravel supplied rst, using the funnel sent with the Pro-OX lter.
3. Next add Pro-OX. Tank should not be more than about 2/3 or at most 3/4 full.
4. Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube when re‐
moving cap or tape.
5. Add 2 cups of household bleach down the inside of the distributor tube and ll tank completely with
water. Allow to soak for at least one hour, although there is no maximum me that the media can be
soaked, prior to installaon and turning it on. This will allow the Pro-OX media to become acvated
and also sanize the media. It will also eliminate the need of “purging” the air out of the tank later.
Add a small amount of silicone grease or vegetable cooking oil to the tank threads and screw on Fleck
2510 control valve carefully. Do not use pipe-joint compound, Teon tape, or Vaseline or other petro‐
leum greases to lubricate tank threads.
6. If red valve handle is in-line with pipe the control valve is in service, not bypass. Move the bypass valve
to the BYPASS posion if not already in bypass.
7. Now install your water pipes to the Fleck 2510 bypass end connectors. Make sure inlet is installed to
the 'In" pipe connector on the bypass valve and outlet is on the “Out” connector.
8. Connect some exible tubing from the drain connecon on the Fleck 2510 control valve to a suitable
drain such as a sepc tank or drain to a sewer. It is OK to run the drain line up and over the Fleck 2510
Neutralizer lter up to 4 feet above the top of the tank. If the drain line will be more than 20 feet, 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 ow rate in the future. Make sure the drain tubing is rmly
clamped to the barbed ng with a hose clamp.
9. For 1.5, 2.0, and 2.5 cubic foot systems only: use external drain backwash ow control. If you have a
1.0 cubic foot system, the ow control is internal and there is no external ow control. Wrap some
Teon tape on the black drain ng, and screw on the ow control as shown below.

10. Plug in your Fleck 2510 control valve to an outlet. Your Fleck 2510 control valve is already pre-
programmed. Adjust the days of the week to backwash every 2 to 3 days for best results.
11. Set the me of day to real me. It will then backwash on that day it is set to backwash, at 2 AM.
12. Now you are ready to turn on the water. Turn on the water and leave the Pro-OX lter on bypass and
check for leaks. Leave the ball valve aer the Pro-OX lter closed, so water is sll o to the house, but
connect a garden hose and open up the hose bib aer the Pro-OX lter and allow the water to run.
This will help to clear out any foreign material that may be in the pipes from the piping installaon. If
you do not have a valve installed aer the Pro-OX lter 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 x‐
ture that does not have aerator screen.
13. Leave the water running out of the garden hose at a slow rate.
14. Turn the manual regeneraon knob to start a manual backwash and rinse cycle.
15. Now you can slowly turn the bypass valve to the service posion which will allow water to enter the
Pro-OX lter.
16. The system must be backwashed once upon startup. First, put the system into service mode. Normally
the system ships in the bypass posion. Once the system is properly plumbed in, make sure to turn
both of the bypass valve knobs 90 degrees into service mode.
17. There should be no Pro-OX media coming out of the drain line, but the water will be gray or dirty look‐
ing. At this point the Pro-OX will be in a backwash mode, which is the rst of two cycles it goes
through during backwash (also called regeneraon”). The backwash takes 14 minutes. The next cycle
is the rinse which takes 8 minutes.
18. Aer the backwash and rinse cycles are complete, repeat the process by turning the manual regenera‐
on knob to start up another manual backwash.
19. Note it is normal for some small amount of Pro-OX dust and nes to come out during the backwash,

Pro-OX 2510 Iron Filter Installaon & Startup Guide

although you do not want to see a large amount of media coming out, which would mean you have very
high water pressure, or the drain ow for the Fleck 2510 is missing.
20. If possible verify that the backwash ow is 10 gallons per minute, which is the recommended backwash
ow rate for 1.0 and 1.5 cubic foot models. If you have a 2.5 cubic foot Pro-OX it should be backwash‐
ing at 15 gallons per minute. You can easily run the drain hose to a bucket and using a watch verify the
ow rate in gallons per minute. An adequate backwash is crical to properly clean the Pro-OX media
and prevent it from cemenng together.
21. Refer to your Fleck 2510 service manual for more informaon about how your control valve is pro‐
grammed if desired.
Maintaining Your 2510 Pro-OX Iron Filter System:
There is lile or no maintenance required. Every 6 – 10 years the Pro-OX media can be replaced for best
results.
Troubleshoong Your 2510 Pro-OX Iron Filter System:
Measure the backwash ow rate by pung the system into a backwash mode and pung the drain tube
into a 5 gallon bucket and ming the ow rate. A 0.75 cubic foot system should ow at 5 gallons in one mi‐
nute, so the 5 gallon bucket should ll in one minute. The 1.0 cubic foot system should ow at 7 GPM dur‐
ing backwash.
Program Sengs
Check to make sure the control valve has been set correctly. In some cases a nightly backwash is required
for best results. Adjust backwash frequency to every 1 to 2 nights if necessary.
What to Do If Your Filter Tank Does Not Sit Level on the Floor
Your black lter tank base is not glued to the boom 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 in order to level it.

Inial Backwash Media Lied Into Control Head
Somemes, when doing the Inial Backwash, the media gets lied up into the control head. You can tell this
happened because you will have lile or no ow, 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 posion.
2) From the Service Mode, iniate a manual regeneraon, by pressing and holding the regen buon (buon
on far le).
3) The valve will advance to the BW (backwash) posion, and start counng down. Press the Regen buon
again, and wait for the valve to advance and stop at the Rapid Rinse (RR) posion.
4) With the valve in the RR posion, open and close the Inlet Bypass valve several mes. Aer the third or
fourth me, leave it in the open posion and check the drain line- do you have a good solid ow? 90% of the
me, the answer is yes, but somemes, even aer opening and closing the valve many mes, you sll don’t
have good ow… But, in either case (good or no ow), connue…
5) With the Inlet Valve OFF, Advance the valve back to Service posion again, and again press and hold the
Regen buon, we are pung the valve back to the Backwash posion.
6) Open the Inlet valve just enough so you can hear the water passing thru the valve- you should noce a
corresponding slow ow out of the drain line. Aer 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 ow… And you will
connue unl the valve is full open.
IMPORTANT:
Any me that you are in the Backwash or Rapid Rinse posion, you may need to unplug the power- this will
hold the valve in its current posion, so it doesn’t ‘me out’ and go to the next posion. When you plug the
valve back in, aer 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 Back‐
wash, when the ow direcon is reversed.
What you are trying to accomplish, aer you have pushed the media back in to the tank in the Rapid Rinse
posion, is to get the Inlet valve all the way open in the Backwash posion, 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 lile bit at a me and let it
run for a few minutes- this is why you may have to unplug it- and then, once you have done that, nally, do
one more backwash, starng with the Inlet valve open, just as it will be when it does it automacally at night.
Once it does that successfully, you are done.

WARNING: Don’t Over-Tighten 2510 Control When Installing on Tank
Tighten with hands, there is no need for a pipe wrench or other wrench.
The control valve is sealed with the o-ring on the base of the control valve. Once you hand-ghten it so the
o-ring has sealed against the top of the tank, connue to ghten for approximately another ¼ turn unl
ght.
If the control valve is over-ghtened and leaks, the black slip ring (see control valve manual, it is #26, part
19197 in the exploded view of the control valve) will need to be replaced.
