Pre‐Installaon
1. Review your packing list and make sure you have received all the parts before beginning installaon.
2. If you will be turning offthe water to your house and you have an electric water heater, shut offthe
power to the water heater before beginning installaon in case the water heater is accidentally drained.
3. 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.
4. 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 iron filter must be allowed to run through a complete backwash
and rinse cycle.
5. Aer the system is installed and running, your water may be discolored or full of sediment or rust,
parcularly if you have older or corroded piping. Typically this clears up over a day or two.
Best Pracces for Piping & Drain Installaon
1. See typical installaon (see Fig 2). The iron filter is installed aer the pressure tank. If you are also
installing a water soener, install the soener aer the Pro-OX filter.
2. Make sure to connect the in pipe to the Canature 85HE inlet and the outlet to the outlet (see Fig. 2). If
you face the Canature 85 HE from the front, the water will enter on the right and exit on the le. The
inlet and outlet are aached to the bypass valve, which is marked with arrows as well.
3. Make sure there is a working gate or ball valve before the Canature 85HE iron 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
(a faucet to which you can aach a garden hose) is strongly recommended aer the iron filter but before
the second ball valve. This makes it easy to rinse your new iron 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 Canature 85HE
control valve. Avoid heang up the Canature 85HE control valve plasc with the torch.
5. You do not need unions to install your Canature 85HE control. If you need to remove it, the Canature

Pro‐OX 8500 Iron Filter Installaon & Startup Guide

www.cleanwaterstore.com Rev 032114
85 HE has quick-release couplings that make it easy to put the iron filter on bypass 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 Canature 85HE control valve 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 require 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 Iron Filter Works
Water enters your iron filter through the top of the tank and flows down through the media and up the
distributor tube. Iron and manganese in the water turns to an oxidized parcle and is trapped upon con-
tact with the media. This type of filter—a downflow filter—can be backwashed to clean and re-classify
the media inside, prevenng channeling. During backwash, the water flow is reversed and flows down
the distributor tube and up through the media, liing, expanding, and cleaning the Pro-OX media.

Fig. 2—Typical Pro‐OX piping installaon with ball valve and hose bib aer the filter. Filter strainer is
oponal, and useful if there is sand or grit in the water. The 25/1 micron filter aer is oponal, and
used when there is very fine sediment or colloidal parcles over 1 micron present.

Assembly and Installaon Instrucons
1. Unscrew by hand the enre Canature 85HE control valve from top of tank if it was shipped screwed on.
Make sure distributor tube is capped; if it is not, wrap it with electrical or duct tape. This will ensure you
don’t accidentally pour gravel or Pro-OX media into the distributor tube.
2. Add supplied filter gravel first, using the funnel sent with your filter. Note: Be sure not to let any parts of
the bag or other foreign materials enter the tank when you are adding media.
3. Next add Pro-OX media—tank should be approximately 60% full
4. Remove cap or tape from top of distributor tube
5. Add 2 cups of household bleach down the inside of the distributor tube and fill tank completely with
water. This will acvate and sanize the Pro-OX media.
6. Note regarding Teflon tape and pipe sealants: It is okay to use Teflon tape and pipe sealant on the
water pipe connector threads, where you aach your pipes or plumbing to the Canature 85HE. DO NOT
USE any Teflon tapes or pipe joint compound on the tank itself or on the threads where the Canature
85HE threads into the tanks. Also note that when installing the 85HE backwash control-mer valve on to
the top of the filter tank, do not over-ghten. Tighten by hand; there is no need for a pipe wrench or
other wrench.

7. See how the Canature bypass valve is connected. Items 2 are the pipe connectors, and items 3 are the
red clips that hold the pipe connectors to the bypass valve. To put the system into bypass or service
mode, don’t remove the red clips, just turn the red knobs (items 1). The 85HE is usually shipped in
bypass mode.
8. Make sure the bypass valve is in the bypass posion when starng the installaon. Follow the IN and
OUT arrows on the bypass valve and control valve for proper connecon of in and out water piping.
Leave in the bypass posion for now.
9. Lubricate the bypass valve o-rings on the pipe connectors with some vegetable oil or silicone grease and
connect the bypass assembly to the Canature 85HE by sliding the bypass valve firmly into the body of the
85HE control valve. Once bypass is in far enough, you can easily insert the red connector clips. Do not
use petroleum grease on any part of the Canature 85HE valve.
10. Now install your water pipes to the Canature 85HE bypass end connectors. Our preferred method is to
wrap the pipe threads 2 or 3 mes with Teflon tape, then apply a thin coang of white, non-hardening
Teflon joint compound paste (available at all hardware store) before aaching the pipe fings. Make
sure inlet is installed to IN pipe connector on the bypass valve, and the outlet to the OUT connector.

11. Connect some flexible tubing from the drain connecon on the Canature 85HE control valve to a suitable
drain such as a sepc tank or sewer drain. It is OK to run the drain line up and over the Canature 85HE,
up to 4 feet above the top of the tank. If the drain line will be more than 20 feet, and especially if your
system is 2.0 or 2.5 cubic feet, use larger diameter tubing such as 3/4” 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. This is
why hard piping the drain line is discouraged. However, you can use PVC piping for the drain line if you
are able to remove it and aach flexible tubing for tesng purposes. Make sure the drain tubing is firmly
clamped to the barbed fing with a hose clamp to prevent leaks.
12. PROGRAMMING: Plug your Canature 85HE control valve in to an outlet.
a. Press and hold Sengs buon for 3 seconds unl TIME OF DAY appears onscreen. Use Up and
Down arrows to set the me, and Sengs buon to confirm. Aer seng the me to AM or PM,
press Sengs again to go to the next seng.
b. The screen should now read YEAR. Set it to the correct year in the same way as you set the me,
and press Sengs to confirm. Do the same for the next two sengs: MONTH and DAY.
c. Aer seng the correct day and pressing Sengs to confirm, the screen should read REGEN
DAYS. This controls how oen the valve will run a regeneraon cycle to clean the media in your
tank. 7 is generally a good seng, though anywhere from 5-7 should work fine. If you use very
lile water you can even set it as high as 14 days. Once you’ve made your selecon, press
Sengs to confirm.
d. The screen should now read GALLONS. Set this to OFF and press Sengs.
e. The screen should now read REGEN TIME. Set this to a me of night (or day) when your system is
not likely to be in use. We generally recommend you set this to 2:00 AM. Once you’ve set the
regen me, press Sengs one final me, so that your screen reads “PROGRAMMING COMPLETE.”
Programming is now complete.
13. Now you are ready to turn on the water. Turn it on and leave the Pro-OX filter on bypass while you check
for leaks. Leave the ball valve aer the Pro-OX filter closed, so that water is sll offto the house, but
connect a garden hose, open up the hose bib aer the filter, and allow the water to run for several
minutes. This important step clears out any foreign material that may be in pipes from the installaon. If
you do not have a valve and hose bib installed aer your filter, you’ll need to turn on the water inside the
house and let it run through a tap that does not have an aerator screen, such as a bathtub or laundry
sink.

14. Press the Manual Regen buon for 3 seconds, unl it beeps. This will begin a manual backwash
(regeneraon) of your system.
15. Now you can slowly turn the bypass valve to the service posion. Do NOT remove the red clips on the
bypass valve in order to do so. First open the inlet side of the valve, then slowly open the outlet side
unl the valve is in full service posion.
16. While there shouldn’t be any Pro-OX media coming out of your drain line, the water may look black or
dirty. Allow the backwash to run (it will take about 10 minutes) unl complete. If the water slows or
stops during the cycle, press any key to skip to the next cycle. Then repeat the backwash and rinse aer
the rinse cycle is done by pressing and holding the Manual Regen buon again. If you have high water
pressure you may need to turn on the water to your filter slowly, to prevent Pro-OX fines from coming
out during the backwash. It is normal for some small amount of fines to escape, however you don’t want
to see a large amount of media coming out. This would indicate very high water pressure or a missing
drain line flow control.
17. If possible, verify the backwash flow rate. You can easily run the drain hose to a bucket and, using a
watch, verify the flow rate in gallons per minute (GPM). For example, if the backwash fills a 5 gallon
bucket in 30 seconds, your well is flowing at a rate of 10 GPM. An adequate backwash is crical to
properly cleaning the Pro-OX media and prevenng it from cemenng together.
1.0 cubic foot model: 5 GPM minimum, 7 GPM recommended
1.5 cubic foot model: 8 GPM minimum, 10 GPM recommended
2.0 cubic foot model: 10 GPM minimum, 12 GPM recommended
2.5 cubic foot model: 13 GPM minimum, 15 GPM recommended
23. The next cycle is the rinse cycle, which runs for 5 minutes. Aer the regeneraon cycle, your Canature
85HE valve will automacally advance to the rinse cycle.
24. Aer the valve has gone through the backwash and rinse cycles, press and hold the Manual Regen buon
for 3 seconds to repeat the cycles again. Remember this procedure, as you’ll have to go through it again
when you add more Pro-OX media in the future (though you shouldn't have to do so for several years).
25. Refer to your Canature 85HE service manual for more informaon about how to program your control
valve.

Maintaining Your Pro‐OX Filter System
Your Pro-OX 8500 iron filter requires very lile maintenance. Simply replace the Pro-OX media every 6-10
years for best results.
If your water has a lot of hydrogen sulfide odor or iron and manganese levels over 10 PPM (parts per
million), a chlorine feed pump may be needed to inject a small amount of chlorine before the well pressure
tank and iron filter. The Pro-OX filter will remove any chlorine tastes or odors. In most cases this is not
necessary, but chlorinaon (or peroxide/ozone injecon) before the filter can greatly enhance the ability of
the media to remove iron, manganese, and hydrogen sulfide.
Troubleshoong the Pro‐OX 8500 Iron Filter
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 minute,
so the 5 gallon bucket should fill in one minute. The 1.0 cubic foot system should flow at 7 GPM during
backwash.
In some cases, the control valve may be programmed incorrectly. Double-check the sengs you have
entered against the procedure outlined above (programming, page 9) to ensure you have entered the
appropriate sengs. In some cases a nightly backwash is required for best results. Adjust backwash
frequency to every 1 to 2 nights if necessary.
If you are sll geng some iron through the system, you can adjust the filter to backwash every 1 or 2 days.
In some cases, if the untreated water is high in hydrogen sulfide, or the iron level is over 5 ppm, a chlorinator
system may be needed before the iron filter in order for the Pro-OX media to funcon properly.
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.
