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 cru-
cial not to mistake the inlet port with the outlet port.
Mistaking and reversing the inlet and outlet ports
will lead to failure of your softener system.
As you work through this guide, please make sure
to follow all instructions exactly and to make spe-
cial note of the bolded instructions and warning
symbols. PDF viewers may click underlined text

Here are the program settings for your softener.
If not all of the values are filled in, you can calculate
the missing values from the exercise on pages
4 and 5 of this guide.
There we will cover the three
essential values of HARDNESS , TANK SIZE , and
SALT SETTING . The remaining filled in values are
the general standards for all softeners.
Initial Programming: When you first plug in your
unit, the control will require you to enter the adjacent
values. Use the UP / DOWN buttons to cycle through
the settings, use the SQUARE / SET button to enter
edit mode, use the UP / DOWN buttons to adjust the
selected setting, and use the SQUARE / SET button
to set it and continue on to the next setting. A more
in-depth guide to programming the Autotrol 268/760
begins on page 11 of this guide.
Editing Program Values: If you wish to edit any of
these individual settings after completing initial pro-
gramming , use the UP / DOWN buttons to highlight
the desired setting, click the SQUARE / SET button
to enter edit mode, use the UP / DOWN buttons to
adjust, and set it with the SQUARE / SET button.
Reprogram: If you wish reprogram entirely , hold
both the SQUARE / SET button and DOWN button
at the same time for 5 seconds until the tank size
shown in cubic feet appears, and then hold just the
SQUARE / SET button to reprogram.

PPM Hardness ÷17.1 = gpg Hardness before Iron
1 ›CalCulatInG HaRdness, CaPaCIty, and BRIne FIll
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) 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 "Hardness" value you use to
program your softener. You may record this in the table on page 2.
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) TANK SIZE: In the first column, identify the section containing your softener Tank Size by either its grain capacity,
amount of cubic feet, or dimensions. To calculate the amount of cubic feet, take the grain capacity of your tank and
divide it by 32K. For example, a 64K grain capacity tank divided by 32K equals a 2 cubic foot tank. Once you have found
the grain capacity and amount of cubic feet for your tank, record these two values in the table on page 2.
6) SALT SETTING: In the first column, identify the section containing your softener Tank Size and then within this
section, find the row pertaining to your Hardness level. Then look under the Salt Setting column to find the most effi-
cient program option to select for your Salt Setting and record it in the table on page 2.
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 20+ 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 20+ 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 6-A
2) If your tank is not filled , place the riser tube
into the tank as shown in Figure 6-B . Please
make sure that the riser tube seats into the
bottom of the tank and that the top of the tube is
about 1” above the top of the tank opening

3) Before filling the tank, place a piece of painter's
tape over the top of the riser to prevent resin
from dropping down inside the riser tube as
shown in Figure 7-A. iAvoid using duct tape
which leaves behind unwanted residue
4) Place the included filling funnel over the top of
the tank as shown in Figure 7-B and prepare to
fill the tank. If your softener system came with
gravel , please pour this into the tank first , then
pour in the included resin media afterwards

1) Remove the filling funnel and tape and while
using the included silicone lubricant packet, lubri-
cate the inner and outer o-rings on the bottom of
the Autotrol 268/760 Valve as shown in Figures
7-C and 7-D
2) Next, install the top screen (standard OR fine
mesh)
to the bottom of the Autotrol 268/760 Valve
as seen in Figure 7-E (you may need to strip the
groove tabs with a razor before attaching). Then
place the valve onto the top of the tank, being sure
that the riser tube fits into the central o-ring on the
valve, as shown in Figure 7-F. Hand-tighten the
valve to the tank. Do not use Teflon tape or pipe
dope on the valve or tank threading

3) Locate the drain port on the rear of the valve,
apply Teflon tape in a clockwise fashion, locate
the included drain barb elbow fitting, and assem-
ble the fitting as shown in Figure 8-A
4) Assemble your ½” I.D. drain line to the drain barb.
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 secure-
ly into place with the included clamp as shown in
Figure 8-B. i Connect the other end of this drain
line tubing securely to a standpipe or drain in
accordance with all local plumbing codes

7) Secure each plumbing adaptor onto the bypass
as shown in Figure 8-E. If you are using copper
connections, first prefabricate and sweat a
12” tube section onto each adaptor and cool
BEFORE assembly to the bypass.
This allows
you avoid overheating the nut and bypass during
future plumbing

1) Before beginning your installation, please first
familiarize yourself with the IN and OUT ports on
the Autotrol 268/760 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 fix-
tures
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

1) Locate the brine port on the right side of the
control valve and apply Teflon tape in a clock-
wise fashion to the threading. Then attach the L
shape fitting to the port (Figure 9-A). Please use
care not to overtighten
2) Locate the included section of Brine Tubing and
assemble the brine fitting to the brine tubing.
Finger-tighten the nut and then use a wrench to
turn the fitting ½ turn more until snug as shown
in Figure 9-B. Please use care not to over-
tighten

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 4 and 5
. Then pull the 474 Brine Float
Assembly
out of the brine well and fix the assem-
bly to the brine well as shown in Figure 10-A
4) Take the other end of your brine line tube, make
sure this end is clean cut, recut if it is not clean,
mark 3/4" from the end of the tube, and insert the
tube through the small hole drilled through the brine
tank and brine well (Figure 10-B)

5) Firmly insert the tubing end 3/4" into the tube
opening on the 474 Brine Float Assembly as
shown in Figure 10-C. i Make sure the tube is
fully inserted into the assembly
6) 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 10-D. 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
7) 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 10-E. Note that this is not necessary
as the 474 assembly is designed to prevent an over-
flow from occuring, but it is a good precaution

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
›ConGR at ul at Ions
Your new softener with Autotrol 268/760 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 ap-
proximately 5 gallons of water/the amount of water needed to cover the brine grid into the brine tank. Start the
regeneration sequence by HOLDING the REGEN button for 5 seconds. Once the hourglass symbol disappears,
let C1 - 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 8 to review preparing the drain connection. Simultaneously click the SET and
UP buttons ONCE to move on to C2 - Regeneration Draw/Slow Rinse
4) Once the hourglass symbol disappears, let C2 - Regeneration Draw run for about 1 minute to observe the
water level in the brine tank being drawn lower. Also check the brine line and connections for leaks. If the
water level doesn't lower or there is a leak, return to pages 9 and 10 to review preparing the brine tank con-
nection. Simultaneously click the SET and UP buttons until you reach C8 - Regenerant Refill
5) Once the hourglass symbol disappears, let C8 - Regenerant Refill run for about 1 minute to observe the water
level in the brine tank rise. Also check the brine line and connections for leaks. If the water level doesn't rise or
there is a leak, return to pages 9 and 10 to review preparing the brine tank connection. Simultaneously click
the SET and UP buttons ONCE to finish
6) 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 immediately after
installation as the new resin arrives at full softening capacity. Simply let your softener meter automatically trigger
regenerations by tracking the water consumption
