Pre-Installaon
1. Review your packing list and make sure you have received all the parts before beginning installaon.
2. If you are going to turn o the water to your house and you have an electric water heater, shut o the
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 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.
4. Get all of your plumbing parts together before beginning installaon. Installaon typically takes 3 to 5
hours, though the Pro-OX 5700-E iron lter must also be allowed to run through a complete backwash
and rinse cycle aer installaon.
5. Your water may be discolored or full of sediment and rust for a day or two aer installing and running
your system, parcularly if you have older or corroded piping.
Best Pracces for Piping & Drain Installaon
1. See typical installaon on page 5 (Fig. 2). The iron lter is installed aer the pressure tank.
2. Make sure to connect to the IN pipe to the CWS 5700-E inlet and the OUT pipe to the outlet (See Fig.
3). If you face the control valve from the front, the water will enter on the right and exit on the le.
From the back, the water enters 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 iron lter and also one aer as shown in 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 lter and before the second ball
valve. This makes it easy to rinse your new iron lter on start-up and gives you a place to test the wa‐
ter before it enters your household plumbing.
4. If you will be using copper piping, do not sweat the copper pipe directly on to the CWS 5700-E control
valve, and avoid heang the valve’s plasc with your torch.
5. If you have copper pipe before the iron lter and it is too dicult to replace, you may sll experience
some copper staining of xtures and have a copper residual in your water, because the copper pipe
will sll have acidic water owing through it. We recommend PEX or PVC pipe up to the iron lter and
then copper aer it, if you will use copper piping.
6. You do not need unions to install your CWS 5700-E control valve. It has quick-release couplings that
make it easy to put the lter on bypass and remove it from your piping.

7. The drain line tubing (not supplied) is connected to a drain from the drain outlet using exible 1/2” ID
tubing. Note that the drain can run up above the CWS 5700-E control valve 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 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
See Fig. 1 below. Water enters your iron lter through the top of the tank and ows down through the
media and up the distributor tube. Downow type lters remove sediment and can be backwashed to
clean and reclassify the media inside, prevenng channeling. During backwash the ow of water is re‐
versed: water ows down the distributor tube and up through the media, liing, expanding, and cleaning
it.

Assembly and Installaon Instrucons
1. By hand, unscrew the enre CWS 5700-E control valve from top of tank if it was shipped screwed on.
Place distributor tube in tank if not already inside. Make sure the tube is capped, or wrap the top of
the tube with electrical or duct tape. This will prevent gravel and Pro-OX media from entering the dis‐
tributor tube when you add them to your tank.
2. Add the lter gravel that came with your system. You want the gravel to cover the boom distributor
screen before adding the Pro-OX media. 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. The tank should be about 2/3 full of media.
4. Remove cap or tape from distributor tube, being careful not to pull up on the tube.
5. Fill tank with water. Add 2 cups of household bleach into the tank. This bleach will acvate and sani‐
ze the Pro-OX media.
6. Add a small amount of silicone grease or vegetable cooking oil to the tank threads and screw on con‐
trol valve carefully.
7. Note regarding Teon tape and pipe sealants: It is okay to use Teon tape and pipe sealant on the
water pipe connector threads, where you aach your pipes or plumbing to the CWS 5700-E control
valve. DO NOT USE any Teon tapes or pipe joint compound on the tank itself or on the threads where
the CWS 5700-E threads into the tanks. Also note that when installing the CWS 5700-E backwash con‐
trol-mer valve on to the top of the lter tank, do not over-ghten. Tighten by hand; there is no need
for a pipe wrench or other wrench.
9. See how the bypass assembly is connected. Note the pipe connectors in Fig. 5, while the other end is
what gets aached to the control valve. Your CWS 5700-E valve is usually shipped in the bypass posi‐
on.

10. Lubricate the bypass valve O-rings with some vegetable oil or silicone grease and connect the bypass
assembly to the control valve by sliding the bypass valve rmly into its body.
11. Next, lubricate the end-connectors with some silicone grease or vegetable cooking oil and insert them
into the bypass valve.
12. Make sure both knobs are in the bypass posion.
13. Now install your water pipes to the bypass valve’s end connectors. Make sure the inlet is installed to
the IN pipe connector and the outlet to the OUT connector.
14. Connect some exible tubing from the drain connecon on the CWS 5700-E 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 lter up to
4 feet above the tank. If the drain will be more than 20 feet, use larger diameter tubing such as 3/4” or
1”. Note that is desirable to be able to run the drain line into a bucket in order to test the backwash
ow rate in the future. This is why hard piping the drain line is discouraged. However, you may use
hard PVC piping for the drain line if you are able to remove it and aach exible tubing should you ever
desire for tesng purposes. Make sure the drain line tubing is rmly clamped to the barbed ng with
a hose clamp to prevent leaks.

Oponal Side Tank Installaon
Fig. 6: Oponal Side Tank Installaon
15. Insert 3/8” diameter tubing into the chlorine side tank connecon. Screw the nut with the sleeve and
Ferrell aached to prevent leaking.
16. Remove the rubber band and felt polypro pad from the tank and discard. Add 2 cups of non-perfumed
household bleach to the tank, followed by 2 gallons of water. Note that the tank may not be used with
solid chlorine pellets or powder, just liquid bleach.
17. Plug your CWS 5700-E control valve into an outlet. Aer being plugged in, the screen may display
“WAITING PLEASE” while it nds the service posion. By default, the control valve will be set to work
like a water soener, which is obviously not correct for this applicaon, so you’ll need to program the
system to work as an iron lter. There are a few sengs that must be changed before the system can
be put into service for this purpose.

Normal Operaon Programming:
Time Mode: Home screen will display days and
hours le unl the unit regenerates.
Meter Mode: Meter mode tracks the number of gallons used instead of regenerang on a
specic me. In this mode immediate regenera‐
on will occur once the unit hits its target calcu‐
lated number of gallons based on hardness
sengs.
Timed Meter Mode: Timed Meter Mode tracks the number gallons used, like the Meter
Mode, but waits unl its set me to regenerate
instead of immediately. A buer period is fac‐
tored in to prevent you from running out of
so water. The water droplet to the right of
Current Time signies the unit tracking water
ow.

Troubleshoong the Pro-Ox 5700-E0 Iron Filter
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
minute, so the 5 gallon bucket should ll in one minute. The 1.0 cubic foot system should ow at 7 GPM
during backwash.
In some cases, the CWS 5700-E valve has simply been programmed incorrectly. Double-check your
sengs against those described above or consult your system’s service manual for instrucons. 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 ad‐
just it by holding the empty tank and rapping it on a concrete or solid oor once or twice in order to level
it.
