7500-Rev4 Pro-Ox AIR Filter Installation Guide
Thank you for purchasing a Clean Water System! With proper installation and a
little routine maintenance your system will be providing iron free water for many
years.
Please review this start-up guide entirely before beginning to install your system
and follow the steps outlined for best results.
The Pro-OX Iron Filter media must be activated with a 1 cup of unscented liquid
chlorine bleach (such as Clorox) when first installing it. Read instructions for
more information. It is easy to do, but a critical step.
The Pro-OX media produces very small particles (fines) when the system is first
installed. Bring the water pressure up VERY slowly during the initial backwash by
opening inlet valve slowly to avoid pushing the media up into the control head.
Performing multiple backwashes at start-up is an important step.
You should also not bring any other systems online (i.e. softeners, filters, etc.) until
the Pro-Ox system is fully flushed. Depending on the water quality, this may take
several backwashes and a week or two of normal water use.
The Pro-OX media contains dust. Use paper mask and ventilate area to avoid
breathing dust when first pouring the media into the tank.
Minimum 30 PSI required. Maximum pressure 90 PSI.
For indoor installation. Protect from sunlight, rain, and freezing.

Pre-Installation
1. Review your packing list and make sure you have received all the parts before installation.
2. 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 accidentally
drained.
3. 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.
4. Get all of your plumbing parts together before beginning installation, and make sure you have
received all of your packages before beginning or scheduling an installation. Installation typically
takes 3 to 5 hours. However, after installation the filter system must be allowed to run through a
complete backwash and rinse cycle.
Best Practices for Piping & Drain Installation:
1. Make sure to connect the Inlet from your water source and outlet, following arrows on control valve
bypass.
2. Make sure there is a working gate or ball valve before the system and also one after as well as a
bypass valve.
3. A hose bib (which is a faucet to which you can attach a garden hose) is strongly
recommended after your filter system and before the second ball valve. This
makes it easy to rinse your filter system on start-up and gives you a place to test
the water.
4. If you will be using copper piping, do not sweat the copper pipe directly on to the 7500-REV4 control
valve.
5. To connect drain line to drain, use an air-gap connection, so that if your sewer or septic tank backs
up, it cannot cross connect with the drain tubing.
6. The pipe connectors are 1’ male pipe thread but you can add a reducer to reduce to ¾” pipe with
common pipe fittings if needed.
7. Make sure bypass valves are closed (system is in bypass) when you first start installing and keep on
bypass until you are ready to start it up with the first backwash.

How the Bypass Valve Works
Turn knob so the valve is bypassed
when installing.
When you go to start up system turn
the bypass SLOWLY to let water in
and put in service.
Installation of Your System in Copper or Metal Piping Systems:
If your new filter system is to be installed in a metal (conductive) plumbing system, i.e., copper, or
galvanized steel pipe, the plastic components of the system will interrupt the electrical continuity of the
plumbing system.
As a result, any stray currents from improperly grounded appliances downstream or potential 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.
Consequently, 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.

How Your Pro-Ox AIR Iron Filter Works
Water enters the top of the tank and flows down through
the media and up the distributor tube.
During backwash the flow of water is reversed and water
flows down the distributor tube and up through the
media, lifting and expanding the Pro-Ox media.
During the backwash the Pro-Ox is cleaned by the action of
the water flowing through it.

Tank Assembly and Installation Instructions:
1. Wrap the top of distributor tube with electrical or duct tape so that no
gravel or Pro-OX media will go down the distributor tube.
2. Add the filter gravel that came with your order. You want the gravel to
cover the bottom distributor screen before adding the Pro-OX media.
3. Next add Pro-OX media, then add the Turbidex media. Tank should be about 2/3rds full of media.
4. Remove tape from top of distributor tube. Be careful not to pull up distributor tube.
5. Add 1 cup of regular chlorine bleach and fill
tank completely with water. Allow media to
soak for 1 hour but 24 hours or more is OK.
6. Add a small amount of silicone grease to the
inner O-ring, where the distribution tube goes.
7. Next, install the top screen by inserting upwards and rotating to lock in place. (This is a funnel-
shaped plastic screen that locks into the bottom side of control valve.
8. Lubricate the main tank O-ring
with silicone grease and screw on
the 7500-Rev4 control valve
carefully. Do not use pipe-joint
compound, vegetable oil, Teflon
tape, or Vaseline or other greases
to lubricate tank threads.
9. Connect bypass assembly with 1”
pipe connectors to control valve
install black clips and make sure
valve is in bypass.
10. Insert meter cable into meter
cable port on bypass.

11. Install inlet and outlet piping (see flow arrows on valve) and hook up drain line tubing to drain.
12. If you are in earthquake zone, strap your backwash filter tank to wall with metal strapping.
13. Proceed to programming your 7500-Rev4 control valve timer and backwash frequency.
IMPORTANT: you must program the time and then start a backwash and rinse. The filter system must
be backwashed and rinsed several times before using. See following pages for instructions.

Start the First Backwash
1After programming, the system must be run
through 2 or 3 backwash/rinse regeneration
cycles to clean the new filter media.
2Start with both bypass valves in the Bypass
Position.
3Press the BACK/REGEN button once to enter the backwashing cycle.
4When the backwash icon is displayed, slowly open the bypass to a quarter position to make
the water flow into the tank and out the backwash drain line to drain.
5After several minutes open bypass valve completely.
6If possible, verify that the backwash flow corresponds with the size of your system below.
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 critical to properly clean the Pro-OX media.
Make sure you have a minimum of these flow rates in gallons per minute. For example, if
backwash water fills a 5-gallon bucket in 1 minute, you have 5 gallons per minute (GPM).

Maintenance
Every 5 to 10 years (in some cases it can last longer) remove control valve and empty the Pro-OX filter
media and replace with new media.
Once a year clean the nozzle and throat on the injector. Turn off water pressure to your system and
release any pressure by opening up a hose bib or faucet downstream of the filter system. Remove the
two bolts covering the injector.
Using small screwdriver remove the injector nozzle and throat and filter screen and clean with paperclip
and rinse in vinegar to remove any deposits.
