What to Do if Your Tank is Not Level Out of the Box:
Your black filter tank base is not glued to the bottom 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 to level.

Pre-Installation:
1. Review your packing list and make sure you have received all the parts before beginning
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 Sediment Filter must be allowed to run
through a complete backwash and rinse cycle.
5. After the system is installed and running, your water may be discolored, or full of sediment or
rust, particularly if this is older or corroded piping. This typically clears up over a day or two.
Best Practices for Piping & Drain Installation:
1. Make sure to connect the Inlet from your water source and outlet, following arrows on control
valve. Connect the External Flow Control fitting onto the Drain line.
2. Make sure there is a working gate or ball valve before the 7500 Sediment Filter and also one after.
A hose bib (which is a faucet to which you can attach a garden hose) is strongly recommended after
the Sediment Filter and before the second ball valve.
3. Your 7500‐S Sediment Backwash Filter must be backwashed and rinsed several times on start‐up.
During the initital backwashes and rinses, keep the valve AFTER the system closed. After
backwashing and rinsing, open up hose bib after system and before closed valve, and run the water.
If water is not clear, perform additional backwash and rinses.
4. If you will be using copper piping, do not sweat the copper pipe directly on to the 7500‐S control
valve. Avoid heating up the control valve plastic with the torch.
5. You should install unions and a bypass around the valve, so that you can remove it and still have
water (See Build Your Bypass).
6. 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.

Installation of Your System in to 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 Sediment Filter
Works:
Water enters the top of the tank and
flows down through the media and up
the distributor tube.
The downflow type Sediment Filter
removes sediment and can be
backwashed, which cleans and re‐
classifies the Sediment, preventing
channeling.
During backwash the flow of water is
reversed and water flows down the
distributor tube and up through the
media, lifting and expanding the
Sediment media.
During the backwash the Sediment is
cleaned by the action of the water
flowing through it.

Assembly and Installation Instructions:
1. Wrap the top of distributor tube with electrical or duct tape so that no
gravel or Sediment media will go down the distributor tube when
adding the media.
2. Add the filter gravel that came with your order. You want the gravel to
cover the bottom distributor screen before adding the Sediment media.
3. Next add Sediment media. The tank should be about 2/3rds full of
media, do not fill more than 2/3rds, even if there is some media left
over.
4. Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube when
removing cap or tape.
5. Fill tank completely with water. This will allow the Sediment Filter media to settle and reduce the
need of purging the air out of the tank later.
6. Add a small amount of silicone grease to the inner O‐ring, where the distribution tube goes.
7. Screw on control valve until tight, by hand.
8. Do not use pipe‐joint compound, vegetable oil, Teflon tape, or Vaseline or other petroleum greases
to lubricate tank threads (where the control valve threads on to the tank, do not lubricate those
threads).
9. Install INLET to Inlet port, and OUTLET from filter to the outlet (see arrows, marked on control
valve)
10. Install drain line flow control on drain line from 7500‐S control valve.
11. Install piping to drain. Be sure to use an air gap so the drain is not connected directly to the drain
or sewer, to avoid cross connection. Do NOT install check valve on drain, use air gap (a gap of air
of 2” between end of drain tubing coming from 7500‐S control valve and opening to the drain pipe
to sewer or septic tank.
12. NOTE: for 2.0 CF sizes and up, use 1” piping for drain. For sizes smaller than 2.0 CF, it is OK to use
5/8” or ¾’ OD plastic tubing.

The 7500‐S Does not come with a pre‐made bypass; you can build one yourself with PVC pipe or can also
purchase our kit. Flex lines may be used where the unions shown where the Elbow Connector is, you
could have slip by male fittings, then flex lines, then male nipples, and then you do not have to worry
about plumbing it with too much pipe deflection‐ this must be avoided, as pipe deflection will put undue
pressure on the control valve threads which may then crack. Reword this
Next, you will need to program the system to work as a Sediment Filter. There are a few settings that
must be changed before the system can be put into service. Plug in the control valve and continue to the
programming instructions.

Set Output Signal Relay Controllers (Generally not used)
Underneath the valve are two relay outputs, one is normally closed contacts and one is
normally open contacts. These can be set to be normally open or normally closed. For this
setting you don’t need to do anything and can be left at b‐01.
Press the Menu/Confirm button.
Normal Operation
Now the display will cycle between:
Current time of Day
Days Left in Backwash Cycle
Time of Regeneration
Display will be locked, and blue Key icon will display.
Initial Backwash:
1After programming, the system must be run through an initial backwash.
2Close Inlet ball valve B and Outlet valve C, and open the bypass valve A, to turn off water
before starting.
3From the initial valve menu, press the UP and DOWN buttons at same time to unlock. Then
press the Green Return/Manual Regeneration button (second button from left) and a the
valve will enter backwash mode. The backwash icon will be lit, and the time will count
down.
4When the backwash icon is displayed, slowly open the inlet valve B to a quarter position to
make the water flow into the resin tank; you should be able to hear air escaping from the
drain pipeline. After all the air is out of the pipeline, open inlet valve B and clean the foreign
materials in the tank until the water is clean.

5Verify that the backwash flow rate coming out of the drain line 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
Sediment media and prevent it from fouling or channeling.

6After the backwash, the system will automatically go into the fast rinse stage. Both stages
will last for as long as you have programmed that cycle step. The control valve will return to
service status (indicated by the up‐flowing meter on the left) after the backwash and rinse
are complete.
7Make sure to backwash and rinse the filter several times to clean up media, repeated
backwash/rinse cycles may be needed when filter is first put on line with new media, to
clean up media and rinse out fines and dust from the naturally mined sediment media.
Congratulations, you are done setting up your valve!

Maintenance:
Normal Operation
‐Normal service display alternates between service days, time of day and scheduled
rinsing time.
‐Days remaining until the next service will count down from the day value to 1 day
remaining.
‐Once the count reaches 1, a service cycle will be initiated at the next designated rinsing
time.
Troubleshooting the 7500 S Sediment Filter:
Backwash Flow Rate
One problem that may occur is if you do not have enough backwash flow rate to properly clean
the Sediment filter.
You can verify the backwash flow rate by running the drain line into a bucket and timing it when
the 7500 S is in Cycle 1 or backwash. A 1.0 or 1.5 cubic foot system should have 5 gallons per
minute and a 2.5 cubic foot system should have 10 gallons per minute of backwash.
