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 offthe water to the house and you have an electric water heater, shut off
the power to the water heater before beginning installaon in case water heater is accidentally drained.
Pick a suitable locaon 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.
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 filter 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 filter 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 filter
before the second ball valve. This makes it easy to rinse your new Pro-OX filter 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 filter on by-pass and remove the filter system
from the piping.
The drain line tubing (not supplied) is connected to a drain from the drain outlet using flexible 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 filter 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 filter tank and flows down through the media and up the distribu-
tor tube. During backwash, the water flow is reversed and water flows 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 flowing through it, so untreated well
water can be used for backwashing. As a final cycle, the Pro-OX is rinsed to drain by water flowing 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 filter gravel supplied first, using the funnel sent with the Pro-OX filter.
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. If possible at this point, fill tank completely with water. This will allow the Pro-OX media to sele and
eliminate the need of “purging” the air out of the tank later.
6. 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, Teflon tape, or Vaseline or other petro-
leum greases to lubricate tank threads.
7. 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.
8. 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.
9. Connect some flexible 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 filter 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 flow rate in the future. Make sure the drain tubing is firmly
clamped to the barbed fing with a hose clamp.
10. For 1.5, 2.0, and 2.5 cubic foot systems only: use external drain backwash flow control. If you have a
1.0 cubic foot system, the flow control is internal and there is no external flow control. Wrap some
Teflon tape on the black drain fing, and screw on the flow control as shown below.

11. 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.
12. Set the me of day to real me. It will then backwash on that day it is set to backwash, at 2 AM.
13. Now you are ready to turn on the water. Turn on the water and leave the Pro-OX filter on bypass and
check for leaks. Leave the ball valve aer the Pro-OX filter closed, so water is sll offto the house, but
connect a garden hose and open up the hose bib aer the Pro-OX filter 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 filter 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 fix-
ture that does not have aerator screen.
14. Leave the water running out of the garden hose at a slow rate.
15. Turn the manual regeneraon knob to start a manual backwash and rinse cycle.
16. Now you can slowly turn the bypass valve to the service posion which will allow water to enter the
Pro-OX filter.
17. 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.
18. 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 first 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.
19. 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.
20. Note it is normal for some small amount of Pro-OX dust and fines 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 flow for the Fleck 2510 is missing.
21. If possible verify that the backwash flow is 10 gallons per minute, which is the recommended backwash
flow 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
flow 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.
22. 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 flow rate by pung the system into a backwash mode and pung the drain tube
into a 5 gallon bucket and ming the flow rate. A 0.75 cubic foot system should flow at 5 gallons in one mi-
nute, so the 5 gallon bucket should fill in one minute. The 1.0 cubic foot system should flow 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 filter tank base is not glued to the boom 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 rapping it on a concrete or solid floor once or twice in order to level it.
WARNING: Don’t Over‐Tighten 2510 Control When Installing on Tank

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

www.cleanwaterstore.com Rev 032114
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.
