Terminator Iron Filter Installation & Startup Guide
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 accidentially
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. Installation typically takes 4 - 6
hours. However after installation the Terminator 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. Typically this clears up over a day or two.
Best Practices for Piping & Drain Installation
1. See typical installation (see Fig 1). The Terminator iron filter is installed after the pressure tank. If
you are also installing a water softener, install the softener after the Terminator iron filter.
2. Make sure to follow to connect the in pipe to the Fleck 2510 inlet and the outlet to the outlet. As you
face the Fleck 2510 control from the front, the water enters on the right and exits on the left. From
the back (see Fig 2) the water enters on the left. The inlet and outlet are attached to the bypass valve
which is marked with arrows as well.
3. Make sure there is a working gate or ball valve before the Fleck 2510 Terminator iron filter and also
one after as shown in the diagram Fig 1. The pressure gauges are optional and perhaps not
necessary but a hose bib (which is a faucet that you can attach a garden hose to) is strongly
recommended after the Terminator iron filter before the second ball valve. This makes it easy to
rinse your new Terminator 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 Fleck 2510 control
valve. Avoid heating up the Fleck 2510 control valve plastic with the torch.
5. 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 Terminator filter on by-pass 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. If the drain line will be over 10 feet, use a ¾” or 1” drain tubing or PVC pipe.

How Your Terminator Works
Fig 1 – Piping Flow Diagram

Terminator Iron Filter Installation & Startup Guide
The Terminator air-injection iron filter consists of:
1. Waterite W-988 Air Injector
2. Air mix contact tank with brass air vent
3. Iron filter tank with Fleck 2510 auto-backwash control valve
The Waterite W-988 Air Injector- This is the standard air injector included with all Terminator
systems. This plastic air injector features plumbing connections of the 1” Male Threads and a flow range for
effective air draw of 3.8-16 gallons per minute.
The air injector has an inlet and outlet (see arrow on side of air injector for
proper installation). When the well pump turns on, water enters the air
injector and is split between the nozzle portion of the injector and the bypass
portion. The amount of water entering the nozzle area is regulated by the
bypass screw. The further the screw is tightened (clockwise) into the air
injector the greater the flow of water onto the nozzle.
As water is restricted into the nozzle and enters the venture a vacuum is formed at this point. This vacuum
creates the air draw into the water. As mentioned the further the bypass screw is tightened into the air
injector the greater the air draw during the pump cycle. Also as the air draw increases the water flow rate
through the air injector and to the home decreases.

Air mix contact tank with brass air vent
The air mix tank is pre-assembled, except for the air vent.
The air vent is connected to the top of the air-mix tank.
The function of the air vent tank is to allow some contact
time for the oxygen in the air to dissolve into the water and
to bleed off excess air. The air injection allows the
Terminator filter media to remove iron by increasing the
dissolved oxygen content of the water and converting the
iron to a form that can be filtered out by the Terminator
filter media.
Terminator Iron Filter with Fleck 2510
auto-backwash control valve
In your Terminator Iron Filter the water enters the top
of the tank and flows down through the media and
up the distributor tube. The downflow type iron filter
removes iron and sediment. Every few days the Fleck
2510 automatically backwashes and rinses the filter
media, which cleans the media of all rust and sediment
and re-classifies the media preventing channeling.
During backwash, the water flow is reversed and water
flows down the distributor tube and up through the
media, lifting and expanding the filter media.

Assembly and Installation Instructions
1. Unscrew by hand the entire Fleck 2510 control valve from top of tank if it was shipped attached to
the tank. 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 filter media to go down the distributor tube.
2. Add filter gravel supplied first, using the funnel sent with the Terminator iron filter.
Do not allow any parts of the media bag or other
foreign material to enter tank when adding media.
3. Next mix all the Terminator media you received
together in a bucket. Add the media to the tank using
the funnel provided. Tank will be approximately 60%
full.
4. Remove cap or tape from top of distributor tube.
5. If possible at this point, fill tank to top with water.
6. Attach optional plastic top screen to the under-side of
the Fleck 2510 control valve. It is a funnel-shaped
plastic screen that snaps on to the control valve and
prevents media from being backwashed out to drain during the regeneration cycles.
7. Add a small amount of silicone grease or vegetable cooking oil to the Fleck 2510 control valve threads
and screw control valve carefully onto the softener tank, making sure not to cross-thread. Do not use

Fig 5
pipe-joint compound, Teflon tape, or Vaseline or other petroleum greases to lubricate tank threads.
Please Note: When installing Fleck 2510 backwash control-timer valve on to the top of the filter
tank, do not over-tighten. Tighten by hand. The control valve is sealed with the o-ring on the base of
the control valve. Once you hand-tighten it so the o-ring has sealed against the top of the tank,
continue to tighten for perhaps another 1/4 turn until tight. If the control valve is over-tightened and
leaks, the black Slip Ring will need to be replaced.
8. See how the Fleck by-pass is connected. Make sure the by-pass valve is in the bypass position when
starting the installation. Follow the IN and OUT arrows on the bypass valve and control valve for
proper connection of in and out water piping. Leave in the BY-PASS position for now.
Page 9 www.cleanwaterstore.com Rev 042414
Terminator Iron Filter Installation & Startup Guide
9. Install air injector (with unions to allow easy removal of air injector for cleaning), and a bypass and
valve around air injector (see Fig 1). Connect piping to air mix tank in and outlet. Attach some tubing
to vent of air tank and run outside if necessary.
10. 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.
11. Connect some flexible tubing from the drain connection on the Fleck 2510 control valve to a suitable
drain such as a septic tank or drain to a sewer. It is OK to run the drain line up and over the Fleck
2510 Terminator iron 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.
12. Turn on the water and leave the Fleck 2510 control on bypass and check for leaks. Leave the ball
valve after the Terminator iron filter closed, so water is still off to the house, but connect a garden
hose and open up the hose bib after the Terminator iron filter and allow the water to run for several
minutes. This important step clears out any foreign material that may be in the pipes from the piping
installation. If you do not have a valve installed after the Terminator iron 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 that does not have an aerator screen.
13. Plug in your Fleck 2510 control valve to an outlet.
14. Set Time of Day: press and hold the red button in to disengage the drive gear. Turn the large gear
until the actual time of day it as the time of the day pointer. Release the red button. By setting time
for real time of day, the backwash will occur at 2 AM. If you wish it backwash at a different time of
day, adjust the current time of day setting, or see 3200 Timer Setting Procedure page 13.
15. Set the Days iron filter will backwash: Rotate the skipper wheel until the number “1” is at the red
pointer. Set the days that regeneration (which means backwashing and rinsing) will occur by sliding
the tabs on the skipper wheel outward to expose the trip fingers. Each tab is one day. Finger at red
pointer is tonight. Moving clockwise from the red pointer, extend or retract fingers to obtain the
desired regeneration schedule. If iron is very high (over 4.0 ppm) you may want to set it backwash
every 2 – 3 days, otherwise every 4 days is a typical setting that works well.

16. Turn the program knob slowly a few degrees clockwise to start a manual backwash. You will hear the
piston engage and move the piston to the backwash position. If you wish, you can swing open the
timer assembly to see how turning the knob on the front moves the program wheel on the backside
of the timer. Each pin or hole equals 2 minutes.
17. Now you can slowly turn the bypass valves to the service position and you will hear water rushing out
to drain and start to backwash the filter.
18. There should be no media coming out of the drain line, but the water will be black or dirty looking.
At this point the Terminator iron filter will be in a backwash mode, which is the first of two cycles it
goes through during backwash (also called regeneration”). The backwash takes 10 to 12 minutes.
The next cycle is the rinse which takes 6 minutes.
19. After the backwash and rinse cycles are complete, repeat the process and backwash a second time.
20. If possible verify that the backwash flow is 5 gallons per minute, which is the recommended backwash
flow rate for 1.0 and 1.5 cubic foot models. 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 media and prevent it from cementing together.
21. There should be no Terminator media coming out of the drain line, but the water will be black or dirty
looking. At this point the Terminator iron filter will be in a backwash cycle. The backwash takes 10
minutes. If the water slows down or stops during the first 10 minutes of backwash, press the Extra
Cycle to move the Fleck 2510 control to the next cycle, the Rinse cycle. Then repeat the backwash
and rinse after the rinse cycle is done, by pressing the Extra Cycle again. If you have high water
pressure you may need to turn on the water slowly to the Terminator iron filter at first to prevent
some Terminator fines from coming out the backwash. However it is normal for some small amount
of fines to come out during the backwash, although you do not want to see a large amount of media
Page 12 www.cleanwaterstore.com Rev 042414
Terminator Iron Filter Installation & Startup Guide
coming out, which would mean you have very high water pressure, or the drain flow for the Fleck
2510 is missing.
22. Adjusting the Air Injector “Micronizer”
A. The proper adjustment of the Micronizer to provide a colloidal suspension of the iron is a final and
important step.
B. Close valve after pressure tank before air mix tank. Close down the Micronizer Adjusting Screw
three turns by rotating it clockwise.
C. Open valve after pressure tank and open a faucet in house. Then control the water flow with valve.
D. Drain water from the pressure tank until the pump starts, then immediately turn off valve. Using
the second hand on a watch, time the pump-up cycle (i.e. the time from the low pressure cut-in of
the pump to the high pressure cut-out.) Assume a time of 99 seconds.
E. Re-open valve until the pump starts, then immediately shut the ball/gate valve after pressure tank.
Determine the time of air-draw at the Suction Nozzle. This time should be 30% of the total pump-up
time, (i.e. 30 seconds). If the air draw time is more than 30 seconds, turn the Adjusting Screw
(counterclockwise) slightly. If the draw time is less than 30 seconds, turn the screw clockwise.
Determine the total pump time after each adjustment, since this time will change as the Adjusting
Screw is being reset.
F. If all the iron is not being removed at the 30% setting of the Adjusting Screw, after 4 weeks,
increase the air draw time to 35% of the total pump-up time (35 seconds).
Maintaining Your Terminator iron filter System
Check the air injector to make sure it is drawing air for at least 30% of the pump cycle. Periodic cleaning of
the air injector is required. It can be disassembled and cleaned in rust remover, white vinegar or citric acid
every year or two depending on usage.
If the water pH is acidic, (less than 7.0 pH) it will be necessary to replenish or add more calcite media once a
year.
Every 3 – 5 years the Terminator media can be removed and replaced. This is easily done by putting the filter
on bypass, removing the control valve, and laying the tank on its side. Using a garden hose, flush out the
media on a tarp, clean the tank and refill with new media.

Terminator Iron Filter Installation & Startup Guide
Troubleshooting the Fleck 2510 Terminator iron filter
One problem that may occur is if you do not have enough backwash flow rate to properly clean the
Terminator iron filter. You can verify the backwash flow rate by running the drain line into a bucket and
timing it when the Fleck 2510 is in Cycle 1 or backwash.
If you are still getting some iron through the system, you can adjust the filter to backwash every 1 or 2 days

Terminator Iron Filter Installation & Startup Guide
What to Do If Your Filter Tank Does Not Sit Level on the Floor
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 in order to level it.
Don’t Over-Tighten 2510 control When Installing on Tank
Please Note: When installing Fleck 2510 backwash control-timer valve on to the top of
the filter tank please do not over-tighten.
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-tighten it so the o-ring has sealed against the top of the tank, continue to
tighten for approximately another ¼ turn until tight.
If the control valve is over-tightened 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.
