›General reference
Please take a moment to review this page in order to
familiarize yourself with these four ports on the valve
and the programming values below. It is crucial not to
mistake the inlet port with the outlet port. Mistaking
and reversing the inlet and outlet ports will lead to fail-
ure of your softener system.
As you work through this guide, please make sure
to follow all instructions exactly and to make special
note of the bolded instructions and warning symbols.

To the right are the program settings for your soften-
er. If not all of the values are filled in, you can
calculate the missing values from the exercise on
pages 6 and 7 of this guide.
There we will cover
identifying the 3 essential values of H - HARDNESS ,
C - UNIT CAPACITY , and BF - BRINE FILL . The
remaining values that are already filled in are general
standards for all softener sizes and hardness levels.
MASTER PROGRAMMING MODE: To enter in/
check the adjacent values of your system, follow
these steps: With either the up or down arrow
button, change the clock to 12:01 PM, set the time
by clicking the left-most CYCLE / REGEN button,
and then hold both the up and down arrow buttons
for 5 seconds to enter master programming mode.
Change values with the arrow buttons and set each
value and advance to the next setting by clicking the
CYCLE / REGEN button.

If you have a mechanical meter valve, here are your
softener program settings. If you have an SXT valve,
refer to page 4 for your programming values.
If not
all of the values to the right are filled in, you can calcu-
late the missing values below AND with the exer-
cise on pages 6 and 7 of this guide. The remaining

The GC - GALLON CAPACITY equates to the
C - UNIT CAPACITY divided by the H - HARDNESS
minus 15% of the result (Ex: 64K tank / 28 gpg hardness =
2,286 gal; 2,286 gal - 343 = 1,943 gal capacity. Unit Ca-
pacity and Hardness can be determined from pages
6 and 7
). If the result exceeds the highest number on
the dial, use the next smallest Unit Capacity listed on
the table on page 7 . With the front cover off of your
control valve and while looking at the panel on the right
side, pull out and rotate the dial and line up your gallon
capacity with the white dot (Figure 5-A).
Swing open the right panel with the capacity wheel to
the right to reveal the Program Wheel on the opposite
side of the panel (Figure 5-B). To set the regeneration
cycle times with the above input values, place the pins
in the slots surrounding the wheel.
Each slot/pin on
the Program Wheel represents 2 minutes during the
regeneration process.

PPM Hardness ÷17.1 = gpg Hardness before Iron
1 ›calculatInG Your Hardness leVel
1) Water Test: Before start-up, it is crucial that you know your water’s HARDNESS and IRON levels in
order to set up your unit properly.
If your unit is not programmed with your particular hardness level, it will
either regenerate too early or too late. If you do not know your water hardness or iron levels, you can take a
sample of your untreated water to a local pool shop, hardware store, or well driller (city water has no iron)
2) Initial Hardness: Your Hardness test results may be recorded in Grains per Gallon (gpg), Parts per Million
(PPM), or Milligrams per Liter (mg/L). Note that PPM and mg/L are the same measure and both figures can
be used interchangeably. If you get a hardness level in PPM or mg/L, please divide this number by 17.1
to get Grains (gpg).
Ex: If your hardness is measured at 300 PPM, take 300 / 17.1 = 18 gpg before iron
3) H - COMPENSATED HARDNESS: Your Iron results should also be measured in either PPM or mg/L. Take
your level of iron multiplied by 5 and add it to the hardness level from the previous step.
This final figure
will be your Compensated Hardness Level that we will program into your softener system. Ex: If your iron level
is measured at 2 PPM, add 2 x 5 = 10 Grains of hardness to existing hardness total. 18 + 10 = 28 Grains Total
4) The compensated hardness level you just calculated will be the “H” value you use to program your
softener. You may record this in the table on page 4 or 5.
Depending on your compensated hardness
level, you will be able to use a different salt setting for programming and running your softener unit. The
lower the hardness level, the more efficient you will be able to be with salt consumption for regeneration

5) C - UNIT CAPACITY: In the first column, identify the section containing your softener tank size and then within this
section, find the row pertaining to your H - Compensated Hardness level. Then look under the C - Capacity column
to find the most efficient program value to enter for your C - Unit Capacity and record it in the table on page 4 or 5.
Note that your unit capacity program value may actually be lower than the tank’s rated capacity. This is to
accommodate a lower salt dose for regeneration.
6) BF - BRINE FILL: In the first column, identify the section containing your softener tank size and then within this
section, find the row pertaining to your H - Compensated Hardness level. Then look under the BF - Brine Fill column
to find the most efficient program value to enter for your BF - Brine Fill and record it in the table on page 4 or 5.
7) Example: If you ordered a 64K grain capacity system and have 28 gpg compensated hardness, you would look under
the 64K, 2.0 cu ft section and then look under the 25+ gpg row for your particular programming values. Note that the
11x11” and the 15x17” brine tanks are too small for the amount of brine needed to regenerate a 64K grain capacity system
with 25+ gpg hardness. According to the table you would opt for an 18” diameter brine tank with a grid plus 6” legs

1) Choose the final location for your water softener
tank and place the tank upright and level on the
surface. Filling the tank may be necessary on
some systems. Your tank may have also come
pre-filled, and in this case you only need to un-
screw the protective cap as shown in Figure 8-A
2) If your tank is not filled , place the riser tube
into the tank as shown in Figure 8-B . Please
make sure that the riser tube seats into the
bottom of the tank and that the top of the tube is
flush with the top of the tank opening

1) Before beginning your installation, please first fa-
miliarize yourself with the IN and OUT ports on the
Fleck 2510 SXT Meter Valve. In order to prevent
damage to your home and to the softener
system, install the softener according to the
IN and OUT arrows on the softener valve
2) Locate the main shut-off valve for your house
and turn it to the OFF position. If you have a
private well, this valve should be near your well
pressure tank. If you have a city water supply,
your valve should be near your water meter
3) Depressurize and drain your home of water by
turning on all faucets and fixtures in your home,
including those outside
4) Pick your installation point and cut a section of
pipe out to run to and from your softener. In
most cases it is preferred to keep outside
lines UNSOFTENED. If you wish to keep
your outside lines unsoftened, you must
plumb BYPASS lines to run hard water to
these fixtures
5) Using soldered copper, PVC plastic pipe, or flex-
ible connections, plumb the system according to
all local plumbing codes. If using copper pipe,
please pre-fabricate at least a 12” section
of pipe for the IN and OUT bound lines and
use a wet rag on the lines being soldered to
prevent heat damage during soldering
6) Once all connections have been made, place the
system into bypass by either using your existing
3-valve bypass (if ordered with a YOKE adap-
tor), or by switching your included bypass ON (if
ordered with a bypass)
7) Next, gradually open your main valve and allow
all air in your plumbing lines to escape slowly.
Also, you may turn off all outside and inside
faucets and fixtures
8) Check for leaks at your plumbing site for signs
of slow drips and rectify if necessary. Please do
NOT take the softener out of BYPASS as the
installation is not completed yet. Please take
this opportunity to check and re-check the IN
and OUT ports to make sure they are correct
fIGure 10-c
5) Assemble the plumbing adaptor to the valve as
shown in Figure 10-C (your bypass/plumbing
adapter model may vary). When assembling
the clips back onto the valve, leave the first clip
loose, tighten the second clip, and complete the
assembly by tightening the first clip. i Please
lightly tighten the screws into the meter as
overtightening will easily cause cracking
3) Locate the plumbing adapter that was shipped
with your system and disassemble the plumbing
adaptor clips as shown in Figure 10-A
4) Using the included silicone lubricant packet, lu-
bricate the o-rings on the Fleck 2510 SXT Meter
Valve as shown in Figure 10-B

insert, and brine line screen to one end of the
included brine tubing as shown in Figure 11-A.
i Be sure that the tapered side of the black
ferrule faces away from the end of the brine
line and that the tapered side of the white
ferrule faces towards the end of the brine line
2) Next, connect this prepared end of the tubing
to the Fleck 2510 SXT Meter Valve as shown in
Figure 11-B. Tighten the nut to the valve using
a wrench until snugly in place. Be careful not to
over tighten, as you may sever the brine line
3) Locate the brine well and remove the cap. You
may also take this moment to prepare and
insert the brine support grid determined
from pages 6 and 7
. Then pull the 474 Brine
Float Assembly
out of the brine well as shown
in Figure 11-C
4) Next, fix the 474 Brine Float Assembly to the

7) If you ever need to remove the tube, evenly press on
both sides of the grey ring surrounding the tube and
pull out as shown in Figure 12-A. i Be sure to recut
the end of the tube each time you remove it to
ensure a proper seal when the tube is inserted
8) Finally, use ½” inner diameter (I.D.) tubing to connect
the drain barb fitting on the brine tank to a floor drain
as shown in Figure 12-B. Note that this is not neces-
sary as the 474 assembly is designed to prevent an
overflow from occuring, but it is a good precaution

trol valve as seen in Figure 13-D
5) Next, assemble your ½” I.D. drain line to the drain
barb as shown in Figure 13-E.
Be sure to use rigid
wall ½” I.D. tubing that will not flatten.
Wrap
electrical tape over the drain tubing to prevent a tube
split and clamp the tubing securely into place with the
included blue clamp as shown in Figure 13-F
6) Connect the other end of this drain line tubing se-
curely to a standpipe or drain in accordance with all
local plumbing codes. Be sure that the drain line
is securely in place before putting your softener
in service. During regeneration, there will be
increased flow via this tubing which may cause
the tubing to become loose

to have reached the calculated capacity. Do not
change this value and press the REGEN button
14) The display should now show RT / 2:00 as
shown in Figure 16-B. This indicates the system
will regenerate at 2:00 AM following the day the
water consumption has passed the calculated
capacity. If you prefer an alternate regeneration
time, please enter it here and then press the
REGEN button to advance

1) With one nearby softened faucet running in the COLD position, slowly open your bypass valve or 3-valve
bypass to about ¼ open to allow the air trapped in the softener to escape via your running faucet.
NOTE: Opening the bypass too quickly or too open may damage your softener or plumbing
2) Allow the softener tank to slowly fill with water. After a few minutes, you will see a trickle of water coming
from the cold water faucet. Allow the water to run slowly in this manner for an additional 5 minutes. Next,
with the cold water faucet still running, gradually move your bypass valve to the fully open position.
NOTE: You may see some initial discoloration from the softened water – this is normal and should
dissipate within the first 40-50 gallons of water used.
Turn off the running cold water faucet when the
water runs clear

Your new softener with Fleck 2510 SXT Meter Valve is now properly installed and programmed!
Please maintain your system by keeping the softener plugged-in and always keep your brine tank
filled with salt to at least above the water level. We appreciate your business, and hope that you
enjoy years of trouble-free softened water!
3) i To test the integrity of your new system and all connections , it is strongly encouraged that you
perform a short form regeneration to check for leaks before service.
Begin this process by adding approxi-
mately 5 gallons of water/the amount of water needed to cover the brine grid into the brine tank
4) If you have the mechanical version of the Fleck 2510, begin a regeneration by turning the timer wheel
clockwise, let the regeneration run its full course to completion, and check the entire system for leaks. If you
notice a leak originating from the drain line/connection, return to page 13 to review preparing the drain con-
nection. If you notice a leak originating from the brine line/connections, return to pages 11 and 12 to review
preparing the brine tank connection
5) If you have the electronic Fleck 2510 SXT version, begin the regeneration sequence by HOLDING the
REGEN button for 5 seconds. Once the screen stops flashing BW, let BW - Backwash run for about 1 minute
to observe the water leave out the drain line and check for leaks. If you notice any leaks, return to page 13 to
review preparing the drain connection. Click the REGEN button ONCE to move on to BD - Brine Draw
6) Once the screen stops flashing BD, let BD - Brine Draw run for about 1 minute to observe the water level in
the brine tank being drawn lower. Also check the brine line and the float valve in the brine well for leaks. If the
water level doesn’t lower or there is a leak, return to pages 11 and 12 to review preparing the brine tank
connection. Click the REGEN button ONCE to move on to RR - Rapid Rinse
7) Once the screen stops flashing RR, advance from RR - Rapid Rinse to BF - Brine Fill by clicking the
REGEN button ONCE more. Once the screen stops flashing BF, let BF - Brine Fill run for about 1 minute to
observe the water level in the brine tank rise. Also check the brine line and float valve in the brine well for
leaks. If the water level doesn’t rise or there is a leak, return to pages 11 and 12 to review preparing the
brine tank connection. Click the REGEN button ONCE to finish
8) Now you may add 120-160 pounds of pellet, solar, or block salt to your brine tank. Always keep your brine
tank filled with salt to at least above the water level.
You do not need to perform a regeneration im-
mediately after installation as the new resin arrives at full softening capacity. Simply let your softener meter
automatically trigger regenerations by tracking the water consumption
