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 3 to
5 hours. However, after installation the system 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/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. See typical installation (see Fig 2). The system is installed after the pressure tank.
2. Make sure to connect the IN pipe to the Fleck 7000 inlet and the OUT pipe to the outlet (see Fig 2). As
you face the Fleck 7000 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 7000 system and also one after as
shown in Fig 2. 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 neutralizer filter
and before the second ball valve. This makes it easy to rinse your new filter on start-up and gives you
a place to test the water before it enters your household plumbing. It also makes it much easier to
perform maintenance in the future.
4. If you will be using copper piping, do not sweat the copper pipe directly on to the Fleck 7000 control
valve. Avoid heating up the Fleck 7000 control valve plastic with the torch.
5. If have copper pipe before the neutralizer and it is too difficult to change out, you may still experience
some copper staining of fixtures and have a copper residual in the water because this section of pipe
will still have acidic water flowing through it. We recommend PEX or PVC pipe up to the neutralizer
and then copper after it, if you have copper plumbing.
6. You do not need unions to install your Fleck 7000 control. If you need to remove it, the Fleck 7000
has quick-release couplings that make it easy to put the system on by-pass and remove the filter
system from the piping.
7. 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 Fleck 7000 control and into a drain, it does not

Fleck 7000 Neutralizer Installation & Startup Guide
Page 4 www.cleanwaterstore.com Rev 120215
have to drain down as the filter backwashes under line pressure from your well pump. Most plumbing
codes require an air-gap connection, so that if your sewer or septic tank backs up it cannot cross
connect with the drain tubing.
How Your Neutralizer Works
See Fig 1. In your neutralizer, the water enters the top of the tank and flows down through the media and up
the distributor tube. The downflow type neutralizer removes sediment and can be backwashed, which
cleans and re-classifies the Calcite, 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 Calcite media.
During the backwash the Calcite is cleaned by the action of the water flowing through it.

Assembly and Installation Instructions
1. By hand, unscrew the entire Fleck 7000 control valve from the top of the tank (if it was shipped
screwed on). If not already done, make sure the blue cap is on top of the distributor tube, or wrap
the top of distributor tube with electrical or duct tape. You do not want Calcite to go down the
distributor tube.
2. Next, add Calcite or Calcite-blend media. If you are using a blend of Calcite and Corosex, make sure
to read page 11 for more information on using and adding blends.
3. Remove cap or tape from the top of distributor tube. Be careful not to pull up the distributor tube
when removing cap or tape.
4. If possible at this point, fill tank completely with water. This will allow the neutralizer media to settle
and eliminate the need for purging air out of the tank later.
5. Attach plastic top screen to the under-side of the Fleck 7000 control valve. It is a funnel-shaped
plastic screen that snaps on to the control valve and prevents resin from being backwashed out to
drain during the regeneration cycles.

Fleck 7000 Neutralizer Installation & Startup Guide
Page 7 www.cleanwaterstore.com Rev 120215
6. Do not use pipe-joint compound, Teflon tape, Vaseline or other petroleum greases to lubricate tank
threads. Do not over-tighten when threading Fleck 7000 control valve on to tank. Do not allow hard
piping to cause stress on the Fleck 70000 valve, the pipes should not be pulling down or up on the
valve. Flexible connectors avoid this problem and are recommended.
7. See how the Fleck by-pass is connected. Note that Items 2 in Fig 4 (below) are the pipe-connectors
and the other end is what gets attached to the control valve. Items 3 are the red clips that hold the
pipe connectors to the by-pass valve - we include two extra red clips with the pipe connector kit.
Your Fleck 7000 is usually shipped in the by-pass position.
Fig 3 - Bypass Assembly
8. Lubricate the by-pass valve o-rings with vegetable oil or silicone grease and connect the bypass
assembly to the Fleck 7000 control by sliding the bypass valve firmly into the body of the Fleck7000.
Once the bypass is in far enough, you will be able to insert the red connector clips. DO NOT USE
PETROLEUM GREASE ON ANY PART OF THE FLECK 7000 CONTROL VALVE.
9. Next lubricate the end-connectors (#2 in Fig 4) with silicone grease or vegetable cooking oil and insert
them into the bypass valve, then insert the red clips (#3 in Fig 4).
10. Note that the Fleck 7000 is usually shipped in the bypass position. There is a bypass valve knob on
both the inlet and the outlet (#1 in Fig 4). You can easily tell if it is in bypass because the two holes on
the bypass knob will be in the vertical position. If the valve is in the Service position (which is the
filtering position or ‘in service’ position) the holes will be in the horizontal position. Make sure both
sides are in the by-pass position (Fig 5, below).

Fleck 7000 Neutralizer Installation & Startup Guide
Page 8 www.cleanwaterstore.com Rev 120215
Fig 4 - Bypass and Service Modes
11. Do NOT remove the red clips in order to put the bypass valve in either bypass or service; it is neither
necessary nor desired to remove the red clips on the bypass valve hand knobs.
12. Now install your water pipes to the Fleck 7000 bypass end connectors. Make sure the inlet is
installed to the 'In" pipe connector on the bypass valve and outlet is on the “Out” connector.
13. Connect some flexible tubing from the drain connection on the Fleck 7000 control valve to a suitable
drain such as a septic tank or sewer drain. It is OK to run the drain line up and over the Fleck 7000
Neutralizer 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. This is why hard piping the drain
line is discouraged: however, if you do use hard PVC piping for the drain line, and you are able to
remove the hard PVC drain piping and attach flexible tubing should you ever desire for testing
purposes, it is OK to use rigid PVC pipe for the drain. Make sure the drain tubing is firmly clamped to
the barbed fitting with a hose clamp to prevent leaks.

Fig 5 –Backwash Drain Flow Control Installation
14. Smaller neutralizer systems use a 90 degree fitting, while the larger sizes use a straight fitting. For the
straight fitting, the flow control goes in first, and then the fitting. Then simply connect your plumbing
using Teflon tape on the threads.
15. Plug your Fleck 7000 control valve into an outlet. Your Neutralizer 7000 control valve is already pre-
programmed. All you need to do is to set the time of day, and then set the number of days the
Neutralizer filter will run before it backwashes and regenerates automatically. The default number of
days between back wash is 7.
16. Press and hold either the Up or Down button until the programming icon replaces the service icon
and the parameter display reads TD. Set the time of day by pressing the up or down arrows until it is
the current time of day. When the desired time is set, press the Extra Cycle button to resume normal
operation, or wait 5 seconds and the unit will return to normal operation if no button is pressed.
17. Hold down the Up and Down buttons at the same time for 5 seconds. Set the number of days
between backwashes, typically for 7 days. If your water is very clean (no sediment or iron) you can
set the backwash frequency to as little as every 14 days, but if not it is best to leave it to backwash
every 7 days.

Fleck 7000 Neutralizer Installation & Startup Guide
Page 10 www.cleanwaterstore.com Rev 120215
18. Press the Extra Cycle button once. Set the time of night that you want the Neutralizer filter to
backwash; the default time is 2:00 am. Adjust the time by pushing the up or down arrow if desired.
19. Now press the Extra Cycle button once more. You are done programming!
20. Now you are ready to turn the water on. Turn the water on, leave the neutralizer on bypass and
check for leaks. Leave the ball valve after the Neutralizer filter closed, so water is still off to the
house, but connect a garden hose and open up the hose bib after the Neutralizer 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 Neutralizer filter
and you do not have a hose bib, you will need to turn the water on inside the house and let it run.
Use a bath tub, laundry sink or other fixture that does not have an aerator screen.
21. Press the Extra Cycle button for a second or two which will start a manual backwash. If you ever wish
to stop a backwash in progress, just push the Extra Cycle button once, and within 30 to 60 seconds
the control valve will change to Rinse cycle. Press the Extra Cycle button again, and it will skip
through the Rinse cycle to Service mode, meaning it is in service and ready to use.
22. Now you can slowly turn the bypass valve to the service position. You do NOT remove the red clips
on the bypass knobs in order to turn the bypass valves from the bypass to the service position. First
open the Inlet Side of the bypass valve. Second slowly open the Outlet Side of the bypass until it is in
the full service position. The Fleck 7000 bypass valve knobs are a little stiff, so you can use a screw
driver placed in the holes to turn the knobs. Make sure you are turning the bypass valve knobs in the
correct direction (counter-clockwise) as you face the bypass valve knobs.
23. There should be no Calcite media coming out of the drain line, but the water will be milky or dirty
looking. At this point the Neutralizer filter is in a backwash cycle which will take 10 minutes. If the
water slows down or stops during the first 10 minutes of backwash, press the Extra Cycle to move the
Fleck 7000 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 to the neutralizer slowly at first to prevent some Calcite fines from coming out the
backwash. It is normal for a small amount of fines to come out during the backwash, but you do not
want to see a large amount of media coming out as this means you have very high water pressure or
the drain flow for the Fleck 7000 is missing.
24. If possible verify that the backwash flow is 5 gallons per minute, the recommended backwash flow
rate for 1.0 and 1.5 cubic foot models. If you have a 2.5 cubic foot neutralizer it should be
backwashing at 10 gallons per minute. 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 Calcite media and prevent it from cementing together.
25. The next cycle is the Rinse cycle and this also runs for 10 minutes.
26. After the neutralizer has gone through the backwash and rinse, press the Extra Cycle button and
repeat the backwash and rinse. This is the same procedure that needs to be done each time you add
Calcite media in the future; the Calcite media must be thoroughly backwashed and rinsed.

Fleck 7000 Neutralizer Installation & Startup Guide

27. Refer to your Fleck 7000 service manual for more information about how your control valve is
programmed if desired.
Maintaining Your Neutralizer 7000 Filter System
1. Check the pH before and after the neutralizer. You want to have a pH of at least 7.0 after the
neutralizer filter.
2. If the pH drops below 7, check the depth of the Calcite media by shining a bright light through the
tank. Your tank should be about 2/3rds full of media. When the media level drops to ½ full, it is time
to add more Calcite or Calcite blend media if you are using a blend.
3. For most residential applications, adding Calcite media once or twice a year is adequate. Do not fill
more than 3/4ths full; about 2/3rds full is best.
How to Add Calcite Media to the Fleck 7000 Neutralizer Filter
CALCITE MEDIA CONTAINS DUST. USE PAPER MASK OR VENTILATE TO AVOID BREATHING DUST.
1. Begin by putting the neutralizer filter on bypass, or turning the water pressure off before the
neutralizer.
2. Initiate a manual backwash cycle. Since it is on bypass, this will relieve the pressure inside the
control valve so you safely unscrew the Media Fill Plug located on top of the neutralizer tank.
3. Unplug the control valve cord from the wall outlet.
4. Unscrew the media fill plug with channel locks or pliers, and using a tube or hose siphon 2 to 3 gallons
of water out of the filter tank. If you don't siphon water out before adding filter media, water will
flow out the fill plug hole and onto the floor. If water on the floor is OK, then you do not have to
siphon water out first before pouring Calcite media into the fill plug hole.
5. Add neutralizer filter media until the tank is 2/3rds full. Do not over-fill; be sure to leave at least 12"
of free space above the media to allow room for it to expand during a backwash.
6. Put the top fill plug back in. You can lubricate the threads with some vegetable oil or silicone grease,
but do not use Teflon tape or plumbing grease.
7. Plug the control valve back in and press the Extra Cycle button so the Fleck 7000 control is in a
backwash cycle.
8. Turn on the bypass valve - slowly at first - back to the service position (if it is in "service" this means it
is in the proper position for filtering and neutralizing).
9. Allow the system to go through a complete backwash and rinse cycle. Repeat this backwash and rinse
cycle by starting another manual cycle, so the neutralizer is thoroughly backwashed and rinsed before
going back into service.

When to Use Calcite Blends
If the water pH is less than 6.0, Calcite alone may not be enough to bring the pH up to the desired range of
7.0 to 7.8. In this case, a blend of Calcite and Corosex should be used. Calcite is a calcium media consisting of
calcium carbonate and will raise the pH slowly. Calcite will not raise the pH much over 7.2. Corosex is a
natural mineral media consisting of magnesium oxide. It reacts much faster and raises the pH much higher
than Calcite alone.
Corosex is almost never used alone as it will raise the pH too high and in some cases will over-correct and
create a highly basic (high pH) condition. It can also cement together like concrete in the neutralizer tank if
you add too much and there is not sufficient backwash.
For most residential well applications, a 90% Calcite and 10% Corosex is best. However, in some cases an
80%/20% mix or even a 70%/30% is used. It is always better to start with a 90%/10% mix at first as this
solves the majority of low pH problems in the range of 4.5 to 5.9.
For a pH of 6.0 to 6.9 use Calcite alone.
For a pH of 5.0 to 6.0 use a blend of Calcite and Corosex usually 90% Calcite and 10% Corosex, or more
Corosex as needed if the pH is less than 5.0.
How to Mix and Use Calcite Blends
The Calcite and Corosex media is sold and shipped in separate boxes. It does not have to be completely
blended together to use as it will mix during the backwash and rinse cycles. Still, when you are adding the
Calcite and Corosex it is better to blend it lightly in a 5 gallon bucket and then add it. You can also add some
Calcite and then add some Corosex as you are filling the tank. Do not fill tank more than about 2/3rds full.
Note the following:
Calcite is shipped in 50 lb boxes and one box of Calcite is equal to 0.55 cu ft.
Corosex is shipped in 10 lb boxes and 1 box is equal to 0.13 cu ft.
50 lbs of Calcite = 0.55 cubic foot of media
50 lbs of Corosex = 0.66 cubic foot of media

Troubleshooting the Fleck 7000 Neutralizer Filter
pH is Too High!
If the pH after your neutralizer is greater than 8.5, your pH kit may turn the color of the reagent, a purple
color. This is nothing to be alarmed about. In some cases, too much Corosex added to the neutralizer-
Calcite-Corosex blend can cause this problem; it almost never happens with Calcite only systems. If this
happens, set the backwash cycle frequency to every night for a couple of weeks, which will cause the media
to be washed more thoroughly and use up the excess Corosex. Alternatively, you can manually backwash it
several times on a given day, etc. Secondly, you can open up the bypass valves slightly, and allow some
untreated water to lower the pH by blending in some lower pH water. When you go to add more media in 6
to 12 months, just add less Corosex.
pH is Too Low!
This can happen if the water entering the neutralizer has a pH less than 6.0. Generally the water after your
neutralizer should have a pH of 7.0, and the pH reagent in your pH test kit should turn a light green to darker
green depending on the pH. Give your neutralizer some time, and after several weeks, if the pH is still
coming out less than 7 and the test reagent is yellowish in color, you may need to add some Corosex to the
neutralizer tank to raise the pH. Contact our office if you don’t have any Corosex on hand and/or you ordered
a Calcite-only system. The Calcite-only systems work best if your water’s pH is between 6 and 6.9 and are
desirable as they add fewer minerals to the water, so it is best to start out with a Calcite only system if your
pH is 6.0 to 6.9. This works for a majority of our customers.
White Spots on Fixtures and Glasses
Calcite neutralizers work by adding natural calcium minerals to the water. Many natural well or spring
waters that are acidic (with a pH of less than 7.0) are low in minerals and are considered “soft” water. This
lack of natural buffering calcium minerals contribute to the corrosive nature of these waters. After the water

Fleck 7000 Neutralizer Installation & Startup Guide
Page 14 www.cleanwaterstore.com Rev 120215
has passed through the neutralizer, the water will be higher in calcium and “harder” but typically not hard
enough to warrant a water softener, which removes calcium hardness.
It is more common to see some white film or spotting on fixtures if you are using a blend of Calcite and
Corosex. In some cases, it might be that too much Corosex was used originally in the mix of media.
If you are starting to see white spots and films on surfaces after the neutralizer has been installed, you might
want to take these steps:
Set the backwash frequency for every 3 days for a couple of months.
Check the hardness level before and after. If your hardness is higher than 5 grains per gallon after the
neutralizer, your neutralizer may be adding more minerals than is needed, and you can open up the bypass
valves a slight amount in order to blend in some untreated water.
Check the pH before and after. You only need the pH to be in the 7.0 to 7.5 range. If the pH is higher than
that, you may be adding more minerals than is necessary.
Backwash Flow Rate:
One problem that may occur if you do not have enough backwash flow rate to properly clean the Neutralizer
filter is a drop in water pressure, due to fouling of the media from rust or sediment. You can verify the
backwash flow rate by running the drain line into a bucket and timing it when the Fleck 7000 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.
Programming:
In some cases, the Fleck 7000 may not be programmed correctly. Your Fleck 7000 should be set for FLTR or
Filter mode and have two cycles, backwash and rinse. However, if you have a built-in flow sensor, it needs to
be programmed differently. Please contact our office for the programming guide on how to set the Fleck
7000 if you have a built-in flow sensor that tracks gallons used.
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.

Fleck 7000 Filter System (Non Flow Sensor) Standard
Programming Guide Standard
This is for the standard MangOX filter systems that do NOT have the optional flow sensor. If your system is
equipped with a flow sensor, see next section (Page 15). There are two types of programming, standard
USER PROGRAMMING, where you can set the time of day and days between backwashes. The second type is
MASTER PROGRAMMING where you can set the length of the backwash and rinse cycles, and make sure the
control is set to the correct settings for your type of MangOX filter:
User Programming
1. Press and hold the Up and Down buttons simultaneously for five seconds while in service, and while
the time of day is NOT set to 12:01 PM.
2. Day Override (Display Code DO): Set to 1 to 14 based on your particular filter system requirements.
Use the Up or Down arrows to change the setting. This is the critical setting that allows your filter to
backwash every fixed number of days. See your Installation and Start-up Guide for more information
or contact us for suggestions for this setting. Press the Extra Cycle button.
3. Regeneration Time (Display Code RT): In general set to 2:00 am or sometime when no water is being
used, and no other filter or softener is likely to be in a regeneration cycle. Press the Extra Cycle
button.
4. Press the Extra Cycle button to end User Programming Mode. The timer will exit Diagnostic Mode
after 60 seconds if no buttons are pressed. Press the Extra Cycle button to exit Diagnostic Mode at
any time.

Fleck 7000 Metered Flow Sensor Filter System Programming Guide
This is for Fleck 7000 backwash filters that have are equipped with the optional built-in flow sensor only.
There are two types of programming, standard USER PROGRAMMING, where you can set the time of day and
gallons of water used and/or days between backwashes. The second type is MASTER PROGRAMMING where
you can set the length of the backwash and rinse cycles, and make sure the control is set to the correct
settings for your type of Neutralizer filter:
User Programming
You can go into User Programming and make adjustments if you want to the flow meter setting or Day
Override setting. Use the User Programming to avoid having to go through the Master Programming for quick
changes to these settings below:
1. Press the Up and Down buttons for five seconds while in service, and the time of day is NOT set to
12:01 PM.
2. Day Override (Display Code DO): Set to 1 to 14 based on your particular filter system requirements.
Use the Up or Down arrows to change the setting. This is the critical setting that allows your filter to
backwash every fixed number of days. See your Installation and Start-up Guide for more information
or contact us for suggestions for this setting. Press the Extra Cycle button.

3. Regeneration Time (Display Code RT): Set to 2:00 am generally or sometime when no water is being
used, and no other filter or softener is likely to be in a regeneration cycle. Press the Extra Cycle
button.
4. Feed Water Hardness (Display Code H): Use this setting to adjust the feed water hardness. Set to 20
for most applications. Press the Extra Cycle button. Note that actual ‘Feed Water Hardness” is
irrelevant to filter systems, since hardness is being removed.
6. Press the Extra Cycle button to end User Programming Mode
Master Programming Mode (for Flow Sensor type)
Perform a Master Reset: Unplug the Fleck 7000 from the electrical wall outlet. Hold the Extra Cycle button
while plugging in and powering up the unit. This resets all of the parameters in the unit.
Enter Master Programming Mode: Set the Time of Day display to 12:01 P.M. Press the Extra Cycle button (to
exit Setting Time of Day mode). Then press and hold the Up and Down buttons together until the
programming icon replaces the service icon and the Display Format screen appears.
Note that when the Master Programming Mode is entered, all available option setting displays may be viewed
and set as needed. Depending on current option settings, some parameters cannot be viewed.
1. Display Format (Display Code DF): Set display to GAL (stands for U.S. Gallons), or change to Liters or Cubic
Meters if out of the U.S. Press the Extra Cycle button to go to the next step.
2. Valve Type (Display code VT): Set to DF2b. This means it is set for standard Down-flow mode, similar to a water
softener so that we can take advantage of the flow meter in this Fleck 7000 5-cycle valve, but we won’t be using
all 5 cycles that the water softeners use. Press the Extra Cycle button to go to the next step.
3. Control Type (Display Code CT): Set to Fd. This is the Meter Delayed option. This tells the Fleck 7000 control to
meter or keep track of the amount of water used, but wait until the pre-set regeneration (backwash and rinse
cycles) time, typically in the middle of the night. Press the Extra Cycle button.
4. Unit Capacity (Display Code C): Set to 30. Use this display to set the Unit Capacity. This setting specifies the
treatment capacity of the unit. Since we are not using this for softening, where the capacity of the softening
resin can be accurately defined, 30 is a number we can start with. This can be set higher or lower later which
will allow the meter to backwash more or less frequently based on the capacity. Press the Extra Cycle button.
5. Feed water Hardness (Display Code H): Set to 10 to 20. This is the feed water hardness that allows the meter to
calculate the number of gallons between backwashes. It is a little meaningless for filter valves, and is designed
for water softeners which remove calcium hardness in grains per gallons. However, if you set it to 20 to start
with, you will later see the number of gallons between cycles when you are finished programming based on
your size of system. It is not that critical because you want the filter to backwash once a week or every few days
based on the type of filter system you have, by setting the Day Over-Ride.
6. Reserve Selection (Display Code RS): Set to SF. It is not relevant to filter control valves.
7. Safety Factory (Display Code SF): Set to 0.

8. Day Override (Display Code DO): Set to 1 to 14 based on your particular filter system requirements. Use the Up
or Down arrows to change the setting. This is the critical setting that allows your filter to backwash every fixed
number of days. See your Installation and Start-up Guide for more information or contact us for suggestions for
this setting. Press the Extra Cycle button.
9. Regeneration Time: (Display Code RT): Set to 2:00 am generally or sometime when no water is being used, and
no other filter or softener is likely to be in a regeneration cycle. Press the Extra Cycle button.
10. Regeneration Cycle Step Times: Use this display to set the various minutes of each cycle. Some of the cycles will
be set to 0. Do not set any of the cycles to Off. Use the Up or Down arrows to change the setting to the desired
setting. Press the Extra Cycle button to accept the setting and move to the next parameter.
a. B1 –Backwash: Set to 8 to 10 minutes.
b. BD - Brine Draw: Set to 0.
c. B2 - 2nd Backwash: Set to 0 for most applications.
d. RR - Rapid Rinse: Set to 6 to 8 minutes
e. BF - Brine Fill: Set to 0.
f. SV - Service (meaning it is in Service or filtering mode) no setting is needed for this. Press the Extra
Cycle button
11. Flow Meter Type (Display Code FM): Set to t1.2 (this is standard Fleck 7000 meter). Press the Extra Cycle button.
12. Press the Extra Cycle button to save all settings and exit Master Programming Mode. Note that the control
valve may take several minutes to re-home and re-set after the Master Programming steps, do not unplug the
control during this process.

How to Remove the Red Clips from Fleck 7000 Control Valves without Breaking
Them
The Fleck 7000 is a great programmable control valve that lasts many years. While it is easy to install and
program, reading this guide prior to installation can save you some time when removing the red clips.
What happens is, when the water is first turned on and the control valve comes up to line pressure, the
bypass valve and pipe connectors push out or push apart slightly and lock in the red clips. When the water is
turned off, and even if there is no water pressure, it’s impossible to remove the jammed in clips, without
great difficulty, and eventually most customers end up breaking them to get them out.
Step 1: Turn off water to the Fleck 7000 and relieve the water pressure by opening up a faucet in the house.
You can also put the Fleck 7000 on bypass, by turning the bypass valves to bypass. Either way, the 7000
control valve must be depressurized before removing the red clips.
Step 2: At that point they can practically be removed with your fingertips, although a small flat head screw
driver or needle nose pliers works best to pull out the red clips.
