Read all steps, guides and rules carefully
before installing and using your new water
softener. Follow all steps exactly to correctly
install. Failure to follow them could cause
personal injury or property damage. Read-
ing this book will also help you to get all of the
benefits from your water softener.
A Your water softener will remove hardness
minerals and "clear water" iron from water,
up to the limits shown on page 26. It will not
remove other types of iron, acids, tastes and
odors, etc° It will not purify polluted water or
make it safe to drink.
When you see this sign in the book,
is not followed exactly.
A Check with your local public works depart-
ment for plumbing, electric and sanitation
codes. You must follow their guides as you
install your softener.
A Protect the softener and piping from freez-
ing. Damage from freezing voids the softener
warranty.
,_ Be sure the electric outlet for the softener
is grounded the right way to protect the
user from injury or possibly fatal shock.
A THIS SOFTENER WORKS ON 24 VOLTS
ONLY. BE SURE TO USE THE TRANS-
FORMER INCLUDED, AND PLUG IT INTO A
120V OUTLET.

HELPFUL INFORMATION
If you know little about plumbing skills, we sug-
gest you get a book on the subject There are
many good books for do-it-yourselfers on the
basics of plumbing. You can get a low cost book
from Sears Plumbing and Heating departments
that will help you Some basic sweat soldering
tips are on page 7 of this manual
WATER SYSTEM TESTS
HAS YOUR WATER SUPPLY HAD A
CHEMICAL ANALYSIS? Sears has many kinds
of water treating units (see page 4) to correct
different water problems. To know the kind
and size of unit you need, you must first know
what elements are in your house water supply.
A chemical analysis shows the type and
amounts of elements in water. If your water
needs analysis, call or write your nearest
Sears store for help.
CHECK YOUR WATER PRESSURE-- For your
softener to work right, a water pressure of no
lower than 20 pounds per square inch (psi) is
needed in the house water pipes The highest
• pressure allowed in the water pipes is 120 psi If
pressure is over 120 psi, buy and install a pres-
sure reducing valve in the water inlet pipe to the
softener. NOTE: If water pressure during the
day is 100 psi or more, pressure during the
night may go over 120 psi.
If you have a well water system, look at the
pressure gauge to find the water pressure. Call
your local water department if you have city
water. They will tell you what the water
pressure is where you live.
CHECK YOUR WATER FLOW RATE - A water
flow of at least 3 gallons per minute is needed.
A lower flow will keep your softener from work-
ing as well as it should° To make an easy
check of your flow rate, do the following. You
will need a 1 gallon container (can, jar, pail,
etc.).
.
2_
Fully open 2 cold water faucets close to the
point water enters the house.
With both faucets open, fill the gallon con-
tainer at 1 faucet while looking at awatch or
clock to see how many seconds it takes.
3. Empty the container and go the second
faucet (be sure BOTH faucets are still on).
Fill the gallon container at the second
faucet and see how many seconds it takes.
4. Turn off both faucets. Now add the number
of seconds it took to fill the container at
.
both faucets.
A total of 90 seconds, or less, means the
system flow rate is good.

WHERE TO PUT THE SOFTENER
Think of the following points as you choose a
place to put your softener (See Fig 1)
• Place as close as possible to the pressure
tank (well water) or water meter (city water).
e Place as close as possible to a water drain
such as a floor cfrain, laundry tub, sump or
standpipe.
Ao Connect to the house main water pipe BEFORE
THE WATER HEATER Temperature of water
going through the softener must not be more
than 120 F (49 C)
O
Ao
&
,&
A
Keep your outside faucets on hard water to
save soft water and salt.
DO NOT install in a place where the
softener could freeze. Freeze damage
voids the warranty by Sears, Roebuck and
Co. (See page 24..)
• A 120V electric outlet, to plug the
transformer into, is needed within 10
feet of the softener(the softener has a 10
foot power cable). Be sure the outlet and
transformer are in an inside place, to pro-
tect from wet weather.
• Keep the softener out of direct sunlight. The
sun's heat can melt plastic parts.
• Put the softener in a place water damage is
least likely to occur if it develops a leak Sears
or the manufacturer will not repair or pay for
water damage
TOOLS, PIPE, FITTINGS
AND OTHER MATERIALS YOU WILL NEED
To know what tools and materials you will need,
you must first decide how to run in and out pipes
to the softener Look at your house main water
pipe at the point you will con nect the softener Is the
pipe soldered copper, glued plastic, or threaded
galvanized or brass? What is the pipe size?
Now look at the common plans for in and out
piping on pages 6 and 8. Select the drawing
best for you and use it as a guide to plan what
materials you will need_ As you plan your in
and out piping, keep in mind the following
check list. Then get all the materials you will
need.

X/ In and out pipes to the softener must be at
least 3/4 in size Some local codes may tell
you to use_no less than 1 in. pipe size
_/ Use copper, brass, or galvanized pipe and
fittings. Some codes may also allow CPVC
plastic pipe_
_/ Copper and galvanized pipe corrode fast
when connected together.
x/ You can buy adaptors to go from a copper or
threaded main water pipe to CPVC in and out
pipe.
x/ Sears has kits and bypass valves you can buy
to help make installing your softener easier
x/ ALWAYS install a bypass valve or valves.
Either use 3 shut-off valves, or 1 of Sears
special valves Bypass valves let you turn off
water to the softener, but still have water in
the house pipes.
x/ Drain hose (7/16 in. inside diameter) is
needed for valve and salt tank drains. See
steps 9 and 10 on page 11. You can buy
flexible hose at most Sears stores or through
Sears catalog.
If a rigid valve drain is needed to comply
with plumbing codes, Sears has a copper
drain kit (See page 11) to change the
softener to a 1/2 in copper tubing drain.
,/
For electric hook-up you may need a
length of copper wire (See page 13).
TOOLS NEEDED: -common and cross
point (Phillips) screw drivers,slip-joint pliers
and a tape measure or rule. ALSO .
for SOLDERED COPPER- tubing cutter,
propane torch, solid-core solder, paste flux,
emery cloth, sandpaper or steel wool
for THREADED PIPE - hacksaw or pipe
cutter, pipe wrenches, pipe threading tool,
pipe joint compound.

SWEAT SOLDERING TIPS
MEASURING PIPE LENGTHS: Always be sure
to include the length of pipe that goes inside the
fitting, On 3/4 in pipe, this length is about 3/4 in
about 3/_.,
engagement NO YES
(J/.'"pipe)
CUTTING PIPE: Turn the pipe cutter back and
forth around the outside of the pipe Tighten the
pipe cutter slowly with each turn until all the way
through the pipe To keep from crushing or dis-
torting the pipe, do not tighten the cutter too
much atatime File burrs from cutends_
CLEAN PIPE AND FITTING SOLDERING SUR-
FACES: With emery cloth, fine sandpaper or
steel wool, clean the end of the pipe and inside of
the fitting Clean surfaces until they shine Do
not grind off too much material, making the fit
too loose
clean surfaces
thoroughly
CHECK THE FIT: Push the pipeintothefitting as
far as it will go Use-some force to slip together,
but do not hammer or pound If too tight, clean
surfaces until fit is good_
PUT ON PASTE FLUX: Freely apply paste flux on
both cleaned surfaces Place pipe into the fitting
and turn to spread the paste around,
BEFORE SOLDERING, READ THESE SAFETY
GUIDES
A Keep torch flame away from walls, the water
softener, and other materials that will burn
A Do not touch newly soldered pipe with your
hands
Wrap nearby, already soldered joints with a wet
cloth so solder does not melt
Let soldered joints cool slowly Sudden cooling
can crack or weaken the solder
SOLDERING: Light the torch and set to a
moderate flame. Move the flame over and
around the joint to heat pipe and fitting. In a
short time, touch the end of the solder wire to
the lip of the fitting. DO NOT PLACE SOLDER
IN THE FLAME. The solder will melt and draw
into the connection when the pipe and fitting
are at the right temperature. Run the solder
around the lip until the joint is full, Do not over_
fill as solder will run into and harden inside the
fitting. Being careful not to touch the pipe with
your hands, make a quick swipe around the
joint with a cloth to take off excess solder.
Fora good sweat solder joint, the pipe and fitting
must not have any water inside them Water,
when heated by the torch, weakens the solder
and often the joint will leak If you can not keep
the inside of the pipe dry, wad upa piece of bread
intoa ball After putting paste flux on both the
pipe and fitting, place the bread wad into the pipe
and poke in several inches, Put the pipe and
fitting together and solder The bread absorbs
moisture while you are soldering When the
water is turned on, the bread dissolves and is
flushed out an open faucet
LEAKING CONNECTIONS: You can try to
reheat and resolder a leaking joint, but it's usu-
ally best to start over Turn off the water, reheat
and take the pipe and fitting apart Take off all old
solder, cleaning down to the copper surface
Apply new paste flux and solder again

CONNECT THE VALVE DRAIN HOSE
_. Take a length of 7/16" inside diameter (I,D)
drain hose and attach 1 end to the flow
washer housing (FIG, 9) Usea hose clamp to
hold itin place Put the other end of the hose over
a floor drain, or intoalaundrytub (FIG, 9), intoa
sump or standpipe (FIG 10), or into some other
suitable drain, CHECK YOUR LOCAL CODES
IMPORTANT NOTES: [See Fig. 9, 10 and tl]
A Leave an air gap of about 1-1/2'' between
the end of the hose and the drain. This gap
is needed so you don't get a back-flow of
sewer water into the softener° DO NOT put the
end of the hose into the drain or connect
without the air gap,
A Place and support the hose so it does not
kink or have sharp bends. Tie or wire the
hose in place so water pressure will not make
it "whip", Do not pinch the hose shut.
A Keep the hose lower than the flow washer
housing. (In some homes, to get to a drain
you must raise the hose and run it over-head. If
you need an over-head drain, do not raise the
hose more than 8' above the floor. A copper
drain line is best to use__see below.)
COPPER DRAIN KIT: The plumbing codes
where you live may say that you must use a
copper valve drain line, A copper line is also
best to use for an over-head drain. Use a cop-
per drain line if the softener is installed out-
side, or in the sunlighL Heat from the sun
makes many kinds of rubber or plastic hose to
collapse or close up.
You can get the kit shown in Fig. 11 from
Sears. It is put in place of the flow washer
housing that comes with the softener. How to
install guides are in the kit.

INSTALL GROUNDING WIRE BETWEEN
'_4 THE SOFTENER IN AND OUT PIPES
The house cold water pipe (iron or copper)
is often used to ground all electric outlets in
the home. Outlets are grounded to protect you
from shock when you touch any electric ap-
pliance plugged into the outlet. If you didn't in-
stall a 3-valve bypass, or a brass single bypass
valve (FIGo 12), the cold water pipe ground is
broken.
&To restore the ground, take the clamps (2),
screws (2), nuts (2) and ground wire that were
in the small parts bag. Install across the iron
or copper in and out pipes as shown in FIG. 14.
Be sure good contact is made between the
pipe and the clamps. Fasten the ground wire
tightly between the clamps.

Valve
Inlet
ELECTRIC POWER OUTLET FOR YOUR
1 _. SOFTENER
The softener works on 24 volt, 60 Hz elec-
tric power. The included transformer changes
standard 120 volt AC house power to 24 volts.
AYou must plug the transformer into a 120 volt
GROUNDED outlet only. Be sure the outlet is
always "live" so someone cannot turn it off by
mistake.
TO CHECK AN OUTLET FOR GOOD GROUNDING,
use an Underwriters Laboratory (UL) approved
circuit analyzer, (FIG. 15) You can get one at
most electrical supply stores, and at Sears.
When the analyzer is plugged into an outlet, it
has lights to tell you if the outlet is grounded
or not. Use it to check other outlets in your
home.
ATO GROUND THE OUTLET, run a length of 14
gauge copper wire from the outlet box (FIG, 16)
to a METAL COLD WATER PIPE Use a metal
clamp to fasten the wire tightly to the pipeo
IMPORTANT: Be sure the cold water pipe has
direct metal to metal contact all the way to the
ground° Plastic, rubber or other electrically in-
sulating parts such as hoses, fittings, washers
or gaskets can break the direct metal to metal
contact. Also check the water meter (city
water) or the well pump° Install #4 copper
jumper wires, clamped tightly on both ends,
across insulated parts (FIG. 17)_

Remove the center screw from the outlet plate.
Plug in the transformer and use the center
screw, or the screw with the transformer, to
hold it in the outlet.
NOTE: The softener timer is factory set to start
a regeneration (page 15 tells you what
regeneration is) about 15 minutes after the
transformer is plugged ino This first regenera-
tion does 3 things.
1. It fills the salt tank with water to the level
needed.

2. It gets all the air out of the resin tank,
3. It makes the resin bed (See page 15) ready
for service.
The regeneration takes about 2 hours. After
that, soft water goes into the house pipes,
Then you can drain hard water from the water_
heater° (It will take a few days before your hot
water is fully soft if you do not drain the
heater)_ Open a hot water faucet until the
water runs cold, then close faucet, The tank
refills with soft water.

TIME DIAL
About 15 minutes after setting the time, a regen-
eration may begin. It will be over in 2 hours
Your softener is factory set to regenerate (see
page 15) every other day When it regenerates,
it uses the following amount of sail
Model No. 625340400 Cap_ 40 - 4,7 Ibs,
Model Noo 625.340500 High Cap. 50 - 5_7 Ibs.
Model No. 625,,340700 Ex_ High Cap_ 70 - 7,2 Ibs_
For most families, this setting gives enough soft
water for their needs_ After setting the timer
(above) the softener is ready to work for you_
Sometimes, a different regeneration setting is
better Two examples are:
-- If your water has over 20 grains per gallon
(GPG) hardness, with 6 or more persons in the
family. •,
-- If you want to "fine-tune" your softener for
the most efficiency and salt saving

SERVICE
When the softener is giving you soft water, it is
called "Service". During service, hard water comes
from the house main water pipe into the softener.
Inside the softener resin tank isa bed made up of
thousands of tiny, plastic resin beads (FIG 19)
As hard water passes through the bed, each bead
attractsand holds the hardness minerals This is
called ion-exchanging, It is much like a magnet
attracting and holding metals, Water without the
hardness minerals (soft water) flows out of the
softener and into the house soft water pipes
After a period of time, the resin beads become
coated with hardness minerals and they have to
be cleaned This cleaning is called regeneration
Regeneration is started by the timen It takes
place in 4 stages or cycles These are:

REGENERATION
[] BRINING: Salt, dissolved in water, is called
brine Brine cleans the hardness minerals from
the resin beads During brining, the brine is
taken from the salt.storage tank and put into the
resin tank Brine causes the resin beads to let go
of the hardness minerals and they are carried to
the drain The amount of brine needed to clean
the resin depends on 2 things--
-- The amount of resin in the softener
-- How fast the brine goes through the bed
The nozzle and venturi (Fig. 20) make suction
to take brine from the salt tank and put it into
the resin tank. They keep the brine flow down
to a very slow rate to get the best resin clean-
ing with the least salt.
A salt saver valve, in the salt storage tank, meters
the amount of brine used for each regeneration
You can set it for different amounts (See page
22).

[] BRINE RINSE: After the preset amount of
brine goes into the resin tank, the salt saver valve
closes Water keeps flowing in the same way as it
did during brining except for the brine, which
has stopped Hardness minerals and brine flush
from the resin tank to the drain Brining and brine
rinse together total about 77 minutes
HOW YOUR WATER SOFTEN
[] BACKWASH: During backwash, water flows
backwards or UP through the resin tank (FIG.
21). Flow is at a fast rate to flush iron minerals,
dirt and sediments from the bed and to the drain
The bed lifts and expands for good cleaning.
Fresh water also goes to the salt storage tank to
make brine solution for the next regeneration
The backwash cycle is about 11 minutes long.

[] FAST RINSE: Backwash is followed bya fast
flow of water, down through the resin tank. The
fast flow packs the resin bed and gets it ready for
return to service. This cycle is about 6 minutes
long.
After fast rinse, the softener returns to service,
Hard water goes into the resin tank where the
resin bed again takes out the hardness minerals
Soft water goes to the house soft water pipes

AUTOMATIC BYPASS
During the 2 hour regeneration, HARD water
goes through the softener valve and to the house
pipes. If a faucet is turned on, hard water is there
for your needs. However, you should not use hot
water, if possible, because the water heater will
refill with hard water. The softener regenerates
from about 2:00 AM to 4:00 AM,a time when not
rnuch water is used
Because the timer is not as accurate as a clock
16
(See page 14), regeneration time can vary some.
If you get up early in the morning and you can
hear the softener regenerating, change the time
setting on the time dial, Move the dial ahead an
hour or so. Then regeneration will start and end
that much earlier and your water heater will not
refill with hard water if a hot faucet is opened
EXTRA REGENERATION
Sometimes, you may run out of soft water.
This can happen if more than the normal
amount of water is used. For example, you will
use more water if you have overnight guests. If
you do run out of soft water, move the knob on
the face plate to "EXTRA REGEN" (Fig. 23).
Within a few minutes, a regeneration will start.
In 2 hours, you will have soft water again.
The knob will return to "SOFT WATER" by
itself, when the regeneration is over. You can't
stop the extra regeneration after you have
moved the knob to that position•

VACATION
Going on a vacation, or a long business trip?
Just move the knob on the face plate to
"VACATION". The timer will keep on running
and stay at the correct time, but regeneration
will not happen. This will save you soft water
and salt. When you return, move the knob back
to "SOFT WATER".
IMPORTANT: If water to your outside faucets
is softened, move the knob to "VACATION"
while sprinkling the lawn or garden. In "VACA-
TION" the softener bypasses hard water. If
you're washing the car, keep the knob at soft
water. Soft water is ideal for cleaning.
BRINE and SALT
Brine (salt dissolved in water) is needed for
each and every regeneration. The water for
making brine is metered into the salt storage
tank by the softener. However, you must keep
the tank filled with salt.
WHEN TO REFILL WITH SALT: Check the salt
level a few weeks after you install the softener
and every week after that. Refill when the
storage tank is about half full. Never let the
softener use all the salt before refilling.
Without salt, you will soon have hard water.
Fill up to, but not over the nozzle and venturi
(Fig. 25). BE SURE THE BRINEWELL COVER IS
IN PLACE.

NOTE: WATER SOFTENING SALT WITH IRON
REMOVING ADDITIVES
Some salts have an additive to help the
softener handle iron in the water supply,,
Although this additive may help to keep the
softener resin clean, it may also release cor-
rosive fumes that will weaken and shorten the
life of some softener parts,
HOW TO "FliNE=TUNE" YOUR
It's not hard to "fine-tune" your softener (See
page 14), but it does take a few minutes of your
time to do it right. You may save up to 500
pounds or more or salt each year with proper
tuning. Read the following carefully.
To have soft water all the time, the softener
must regenerate 1 or more times in each 6 day
period. How many times to regenerate (set on
the time dial) and the salt saver setting to use
depends on 2 things.
1.The number of people in your home-tellsyou
how much water is used
2. The grains per gallon (GPG) hardness of your
water supply -- listed on your water analysis
report .... see page 4.
The softener regenerates with salt (brine - see
page 15)_ The pounds of salt needed each regen-
eration is set on the salt saver valve The salt
saver on your softener is set for_
.....4.7 Ibs - Model No. 625340400 Capacity 40
._5_7 Ibs_ - Model No_ 625_340500 High Cap. 50
.....7.2 Ibs.- Model No. 625..340700 Ex High Cap. 70
This setting gives you soft water for the longest
time before the next regeneration is needed.
However, you will get more gallons of soft water
for each pound of salt used if the softener is re-
generated more often at a lower salt saver set-
ting. Over a period of time, a lower salt setting
will save you salt, and money_
meeting point, pictures of the time dial and salt
saver show you the settings to use The time dial
picture shows you the button numbers to push
inward (See below)The salt saver picture shows
you the number to set your salt saver at (See
page 22).
SETTING THE TIME DIAL
FOR REGENERATIONS
The time dial (FIG 26) turns all the time and
makes 1 complete turn every 6 days It has 6
buttons numbered from 1 through 6 Buttons
pushed inward start regenerations. Buttons pulled

I HOW TO CARE FOR YOUR
CLEANING THE COVERS
To keep your new Sears water softener looking
nice, apply a coat of paste wax and repeat
once a year. When dusty, wipe it with a damp
cloth to keep it sparkling.
ANever use cleaners having ammonia or abra-
sives. They may scratch and dull the surface
CLEANING THE NOZZLE & VENTURI
Aclean nozzle and venturi(FIG 29) isa must for
the softener to work right. This small unit moves
brine from the salt storage tank to the resin tank
during regeneration If it becomes plugged with
sand, silt, dirt, etc_, it will not move the brine, and
you will get hard water.
The nozzle & venturi parts (FIG. 29) are inside
the plastic housing at the top of the salt saver
(FIG. 27, page 22). Hold the housing with 1
hand and turn to the left (f---.), to remove
parts from the housing_
The filter and nozzle (FIG 29) press-fit together
and you can pull themaparLTakethe nozzle out
of the nozzle housing by turning to the left(F).
The venturi is inside the nozzle housing Usea
small scissors or tweezers to take it out by turn-
A ing to the left. BE .CAREFUL NOT TO SCRATCH
OR DAMAGE THE VENTUR L If it's too tight, soak
the parts in hot faucet water (or vinegar water) to
loosen,
Wash and rinse all parts in hot water until clean
Use small wire to clean plugged holes in the
A nozzle and venturi but, DO NOT MISSHAPE,
MAKE HOLES LARGER, OR SCRATCH SUR-
FACES AROUND THE HOLES. They will not
work if damaged in any way
After cleaning, put the venturi back into the
nozzle housing, turning in until snug° Put the
o-ring on the end of the nozzle housing and
turn the nozzle into the housing. Push the
small end of the filter into the nozzle.
With all parts together, dip into clean water
and turn into the plastic housing on the salt

Nozzle
saver (FIG. 27).. Tighten snugly BY HAND ON-
LY. Do not overtighten or you will break the
plastic housing.
If you have to clean the nozzle & venturi quite
often, you may decide to install a Sears sediment
cartridge filter (See FIG 1, page 4) This filter
takes dirt and sediments out of the water
GETTING IRON OUT OF THE SOFTENER
Your water softener takes hardness minerals
(calcium and magnesium) out of the water Also,
it can control "clear water" iron up to the follow-
ing maximums.
Model No, 625,340400 _2 parts per million (ppm)
Model No, 625_340500 - 2 parts per million (ppm)
Model No. 62&340700 - 3 parts per million (ppm)
With clear water iron, water from a faucet is clear
when first put into a glass. After 15 to 30 minutes,
the water begins to cloud or turn rust colored A
water softener WILL NOT remove any iron if the
water is cloudy or rusty as it comes from the
faucet (called red water iron). To take red water
iron out of water, or over the 2 or 3 ppm maximum
of clear water iron, an iron filter or other equip-
ment is needed. Your local Sears store has trained
people to help you with iron water problem&
If your water supply has clear water iron, even
though less than the 2or3 ppm maximum, regu-
lar resin bed cleaning is needed. Sears has resin
bed cleaner, Stock No. 42-34425 for this Clean
the bed at least every6 months. If iron shows up
in the soft water before 6 months, clean more
often Printed instructions are on the resin bed
cleaner bottle.

BREAKING A SALT BRIDGE
Sometimes, a hard crust or salt bridge forms in
the salt storage tank, just above the salt platform
It is often caused by high humidity (dampness in
the air) or the wrong kind of salt When the salt
bridges, an empty space forms between the
water and salt Then salt will not dissolve (melt)
in the water to make brine. Without brine, the
resin bed does not regenerate and you will have
hard water
If the storage tank is full of salt, it is hard to tell if
you have a salt bridge. Salt is loose on top, but
the bridge is under it The following is the best
way to check for a salt bridge
Salt should lay right on top of the salt platform
Figure 30 shows the distance (D) from the salt
platform to the top of the tank_ Take a broom
handle, or like tool, and make a pencil mark the
correct distance (24", 261/2'' or 32") from one end.
Carefully push the tool straight down into the
sail If a hard object is felt before the pencil mark
gets to the top of tank, it's most likely a salt
bridge_ Carefully push into the bridge in a few
places to break it DO NOT PUSH THE TOOL
APAST THE PENCIL MARK OR YOU COULD
DAMAGE THE SALT PLATFORM. DO NOT TRY
TO BREAK THE SALT BRIDGE BY POUNDING
ON THE OUTSIDE OF THE SALT TANK. YOU
MAY DAMAGE IT..
If the wrong kind of salt made the bridge, (See
FIG. 25, page 17), take it out Then fill the tank
with nugget or pellet salt only
KEEP THE SOFTENER FROM FREEZING
If the softener is installed where it could freeze
(summer cabin, lake home, etc ), you must drain
all water from it to stop possible freeze damage_
To drain the softener --
1. Close the shut-off valve on the house main
water pipe, near the water • meter or: pressure
tank.
2_ Open a faucet in the soft water pipes to vent
pressure in the softener.
3_ Looking at FIG. 12 on page 12, move the stem
