Installation Instructions
UNPACKING AND INSPECTION
WHERE TO INSTALL THE SOFTENER
Be sure to check the entire softener for any
shipping damage or missing parts. Also note
damage to the shipping cartons. Contact the
transportation company for all damage and loss
claims. The manufacturer is not responsible for
damages in transit.
• Place the softener as close as possible to a
sewer drain, or other acceptable drain point
or standpipe.
• It is recommended to keep outside faucets
on hard water to save soft water and salt.
• Do not install the softener in a place where it
could freeze. Freeze damage is not covered by
the warranty.
Small parts needed to install the softener are
packaged either in a bag or box. To avoid loss
of the small parts, keep them packaged until you
are ready to use them. Be sure not to discard
components hidden in packaging.
• Do not install the softener where it would block
access to the water heater or access to the main
water shutoff.
• Put the softener in a place where water damage
is least likely to occur if a leak develops. The
manufacturer will not repair or pay for water
damage.
TOOLS AND MATERIALS REQUIRED
FOR INSTALLATION
• Teflon tape
• A 120-volt electric outlet is needed to plug in the
included transformer. The softener has a 10-foot
power cable. If the outlet is remote (up to 100
feet), use 18 gauge wire to connect. Be sure the
electric outlet and transformer are in an inside
location, to protect from wet weather. Be sure
the outlet is unswitched to prevent accidental
shutoff.
• Razor knife
• One adjustable wrench
• 1/2″ vinyl/pvc drain line (the length required will
be determined by your specific location)
• Additional tools may be required if modification
to home plumbing is necessary.
• If installing in an outside location, you must
take the steps necessary to assure the softener,
installation plumbing, wiring, etc., are as well
protected from the elements (sunlight, rain, wind,
heat, cold), contamination, vandalism, etc., as
when installed indoors. Outdoor installation is
not recommended, and voids the warranty.
• In and out fittings included with the softener
are 1″ copper adapters. You should maintain
the same, or larger, pipe size as the water supply
pipe, up to the softener inlet and outlet. Then,
use the necessary adapters to connect the
water supply to the 1″ copper adapters.
• Use the included bypass valve to install the
softener. The bypass valve allows you to turn off
water to the softener for servicing, but still have
water pressure in the house pipes.
• Keep the softener out of direct sunlight.
The sun’s heat may distort non-metallic
parts and may damage the electronics.
• Use appropriate fitting/pipe material (i.e., copper,
brass, galvanized or CPVC) to connect the 1″
copper adapters to the house plumbing.
• If a rigid valve drain is needed to comply with
plumbing codes, you can buy the parts needed
to connect a 1/2″ copper tubing or plastic pipe
drain.
• Clean nugget or pellet water softener salt is
needed to fill the brine tank.

BEFORE YOU BEGIN
• Turn off the gas or electric supply to the water
heater, in the possibility that the water heater
may be drained while draining pipes.
OPERATION
To bypass the Water Softener with the bypass
valve, rotate the handles clockwise so they are both
perpendicular to the flow path of the inlet and
outlet water stream, as shown below.
• Turn off the water supply to pipes to be cut and
drain the house water pipes.
• Open both hot and cold faucets at the lowest
location possible.
1 INSTALL BYPASS VALVE
• Make sure there is a gasket secured inside the
inlet and outlet union nuts of the bypass. Then
assemble the union nut to the valve inlet and
outlet, hand-tightening both union nuts
To return to the conditioned water or service

4 CONNECT AND RUN THE VALVE
DRAIN HOSE (CONT.)
• Locate the other end of the hose at a suitable
drain point (floor drain, sump, laundry tub, etc.)
that terminates at the sewer. Check and comply
with local codes.
CAUTION:
Observe all of the following
cautions as you connect inlet and outlet
plumbing. See Typical Installation Illustration.
• BE SURE INCOMING HARD WATER SUPPLY IS
DIRECTED TO THE SOFTENER VALVE INLET PORT.
If house water flow is from the right, use a
plumbing crossover as shown in Typical
Installation Illustration.
• With the softener in place, determine the
correct length of piping required to connect the
household plumbing to the 1″ copper adapter
on the softener. Test fit all connections.
• Tie or wire the hose in place at the drain
point. High water pressure will cause it to whip
during the back-wash and fast rinse cycles of
regeneration. Also provide an air gap of at least
1-1/2″ between the end of the hose and the
drain point. An air gap prevents possible
siphoning of sewer water into the softener,
if the sewer should “back-up.”
The water softener will not work if water cannot
exit this hose during regeneration.
NOTE: The softener must not support the home’s
plumbing in the vertical direction. Secure the
inlet and outlet pipes to the wall/ceiling using pipe
clamps or straps. Be certain the home’s plumbing
does not exert any force on the softener bypass.
• Remove softener from installation space.
• Disconnect copper adapters and union nuts from
bypass valve.
• Reconnect copper adapters with union nuts
and gaskets in place to home plumbing. Before
soldering adapters, slide union nuts and gasket
away from area being soldered. NOTE: Torch heat
will damage plastic parts.
• Elevating the drain hose may cause back
pressure that could reduce the brine draw during
regeneration. If raising the drain line overhead is
required to get to the drain point, measure the
inlet water pressure to the softener first. For inlet
pressures between 20 and 50 psi, do not raise
higher than 8′ above the floor. For inlet pressure
above 50 psi, the drain line may be raised to a
maximum height of 14′.
• Support inlet and outlet plumbing in some manner
(use pipe hangers or clamps) to keep the weight
off of the valve fittings.
STANDPIPE
• Slide softener back into position.
• Make final connections to the bypass valve.

OVERFLOW AND HOSE
AND CLAMPS
• Connect overflow drain hose to fitting on side of
brine tank.
IMPORTANT: A copper or galvanized house cold
water pipe is often used to ground electrical outlets
in the home. Grounding protects you from
electrical shock. The water softener may have
broken this ground path. To restore connection,
install UL approved grounding hardware or 6-gauge
copper wire across the softener valve, tightly
clamped, using UL approved grounding clamps at
both ends as shown. Zinc clamps should not be
used on copper plumbing. Grounding hardware is
not provided with the unit. It may be purchased
separately from your local hardware store.
• Locate the other end of the hose at the drain
point. DO NOT ELEVATE this hose higher than the
elbow on the brine tank.
IMPORTANT: DO NOT TEE OVERFLOW HOSE TO
VALVE DRAIN HOSE.
NOTE: This drain is for safety only. If the cabinet
(brine tank) should over-fill with water, the excess is
carried to the drain.
NOTE: Clean copper pipe and ends of wire with
emery paper. Bare wire is recommended. If insulated
wire is used, it should be stripped 3/4″ at each end
before cleaning with emery paper.

START-UP RINSING PROCEDURE
(BYPASS VALVE IS OPTIONAL)
1 OPEN WATER SUPPLY
4 RUN THE WATER
With the plumbing, drain line and overflow
connections completed, slowly open the water
supply, allowing the lines to pressurize.
After the 20-minute purge cycle, manually advance
the main gear to the backwash cycle and allow to
run for a minimum of 10 minutes.
NOTE: The optional bypass should still be in bypass
mode as shown.
After 10 minutes during the backwash cycle, open
both the inlet and outlet valves on the bypass to the
fully opened position.
NOTE: When advancing the main gear manually
while under water pressure, it is normal for the gear
to encounter resistance as the valve chambers
depressurize. If resistance occurs, pause five
seconds to allow the valve to depressurize
before advancing to the next step.
Outlet
Inlet
2 ADVANCE THE CONTROL VALVE
With the transformer unplugged, manually advance
the control valve by depressing the drive gear and
rotating the main system gear to the purge position
(see Step 4).
Advance the gear in the counterclockwise direction
only. Damage will occur if advanced in the opposite
direction.
5 FILL BRINE TANK
3 PURGE THE SYSTEM
After the ten-minute backwash cycle, manually
advance the control valve to the brine refill position
for ten minutes, allowing water to flow into the
brine storage tank.
Slowly open the inlet valve (only) on the bypass
valve to the half-opened position, allowing the
system to pressurize. It is normal to hear air
blowing to the drain during this procedure.
Once the air clears and water begins to run to
the drain, open the inlet valve (only) to the full open
position and allow the water to run to the drain in
purge for a minimum of 20 minutes.
Once water begins to flow into the tank, fill the
brine tank with a minimum of 80 lbs. of salt pellets.

During a power outage, the display will be turned
off and the motor will not run, but the control will
continue to monitor water flow and time. If power is
out and a regeneration is needed, the regeneration
will be delayed until power is restored. If power is
lost during the regeneration, the control will resume
the regeneration when power is restored.
While batteries may
last for over a year, it
is recommended that
you replace the
battery every year.
During an interruption in power supply, a typical
new 9-volt alkaline battery provides approximately
40 hours of power for the control.
If there is a power outage, after power is restored,
verify that the time in the control is correct. If it is,
system is OK. If time is incorrect, set the correct
time in the control and replace the 9-volt battery.
If system has been without power for over 24
hours, initiate an immediate regeneration cycle
by pressing the REGEN button.

following procedure and example:
• Daily Water Usage = number of persons in
household x 80 gallons
For a family of 3
Daily Water Usage = 3 x 80 = 240 gallons/day
• Water Hardness – have the water tested or call
your local water company. For this example, 20
grains is assumed.
• Calculate total grains used per day =
gallons/day x hardness = grains/day

NORMAL OPERATION
ERROR CODES
The control will cycle between TIME OF DAY and
CAPACITY about every 10 seconds, as indicated by
the green indicator light.
This system continuously monitors itself and
displays an error message if it detects something
wrong. This typically happens when the valve has
not advanced through the regeneration cycle
properly.
Capacity in Normal Operation mode is the gallons
of water available until the next regeneration cycle.
When an error is detected, the display shows the
letters “Err” with a number from 1 to 4. The table on
page 24 describes each error, the cause of the error
and the solutions.
During a regeneration cycle, the control will cycle
between TIME OF DAY and REGEN TIME REMAINING.
REGEN TIME REMAINING is the number of minutes
until the regeneration cycle is complete.
To clear the error from the display, press any button
on the control. If the error still exists, the control will
display the error message again after 30 seconds.
MANUAL REGENERATION
Occasionally you may find it necessary to initiate a
manual regeneration. This is done by pressing the
REGEN button on the front of the display. When you
press the REGEN button, the control performs a full
regeneration of the water conditioner immediately.
SOUNDS YOU WILL HEAR
During the regeneration cycle, the softener makes
several sounds. These sounds are normal.
• Clicking sound – This occurs as the valve assembly
advances. It is the opening and closing of the
valve ports.
In the event the system is allowed to run out
of salt, it will be necessary to run “Back to Back”
regenerations. This can be done easily by pressing
the REGEN button one time, waiting at least one
minute and pressing the REGEN button again.
• Harmonic sound – As the valve transitions
between cycles in regeneration, a high-pitched
harmonic noise may be heard for a few seconds.
NOTE: The second regeneration will begin
• Water flow sound – In the backwash and purge
portions of the regeneration, water flow is very
high – 2–3 gpm. This is required to flush the tank
of accumulated minerals and sediments.
immediately after the first is completed.
“Back to Back” regenerations are necessary if full
exhaustion occurs due to low regenerate levels or
system malfunction. The system works on a highly
efficient proportionate-brining method. When the
system is not aware of the lack of proper regenerate
(salt), a larger portion of the resin bed becomes
exhausted.

SANITIZING PROCEDURES
To complete the installation, do the following

faucet tastes salty or has a slight color, this is a
preservative from the resin tank. Turn on the cold
soft water faucets and drain for a few minutes or
until clear.
sanitizing procedures.
Care is taken at the factory to keep your water
softener clean and sanitary. Materials used to make
the softener will not infect or contaminate your water
supply and will not cause bacteria to form or grow.
However, during shipping, storage, installation and
operation, bacteria could get into the softener. For
this reason, sanitizing as follows is suggested when
installing.
NOTE: When the sanitizing regeneration is over,
all remaining bleach is flushed from the conditioner
and your house COLD water supply is fully soft
immediately. However, your water heater is filled
with hard water and as hot water is used, it will refill
with soft water. When all the hard water is replaced
in the water heater, hot only and mixed hot and cold
water will be fully soft. If you want totally soft water
immediately, after the above regeneration, drain the
water heater until the water runs cold.
NOTE: Sanitizing is recommended by the
Water Quality Association for disinfecting.
1. Be sure to complete all installation steps, including
programming the control.
2. Pour about 3/4 oz. (11⁄2 tablespoons) of common
5.25% unscented household bleach (Clorox, Linco,
Bo Peep, White Sail, Eagle, etc.) into the brinewell.
Refer to illustration on page 5.
WARNING:
If you do drain the water
heater, use extreme care as the hot water could
cause burns. Turn the water heater off prior to
draining.
3. IMPORTANT: Press and hold for 3 seconds the
faceplate REGEN button to start an immediate
regeneration. The indicator light will alternate
between TIME OF DAY and REGEN TIME
REMAINING. The bleach will be drawn
through the water softener, and out the drain.
This process takes approximately 3 hours.

softening system resin tank is a bed made up of
thousands of tiny, plastic resin beads. As hard
water passes through the bed, each bead
attracts and holds the hard minerals. This is
called ion-exchanging. It is much like a magnet

hard minerals (soft water) flows from the water
softening system and to the house pipes.
setting) by the water softening system control,
and consists of five stages or cycles. These are
FILL, BRINING, BRINE RINSE, BACKWASH and
FAST RINSE.
Automatic Hard Water Bypass During Regeneration
For emergency needs, hard water is available
to the home during the regeneration cycles.
However, you should avoid using HOT water
because the water heater will fill with the hard
water.
Fill
Backwash
Salt dissolved in water is called brine. Brine is
needed to clean the hard minerals from resin
beads. To make the brine, water flows into the
salt storage area during the fill stage.
During backwash, water travels up through
the resin tank at a fast flow rate, flushing
accumulated iron, dirt and sediments
from the resin bed and to the drain.
Brining
Fast Rinse
During brining, brine travels from the salt storage
area into the resin tank. Brine is the cleaning
agent needed to remove hard minerals from the
resin beads. The hard minerals and brine are
discharged to the drain.
Backwash is followed by a fast flow of water
down through the resin tank. The fast flow
flushes brine from the bottom of the tank,
and packs the resin bed.
After fast rinse, the water softening system
returns to soft water service.
The nozzle and venturi create a suction to move
the brine, maintaining a very slow rate to get the
best resin cleaning with the least salt.
Brine Rinse
After a pre-measured amount of brine is used,
the brine valve closes. Water continues to flow in
the same path as during brining, except for the
discontinued brine flow. Hard minerals and brine
flush from the resin tank to the drain.

Breaking a Salt Bridge
Push tool into salt
bridge to break
Sometimes, a hard crust or salt bridge forms in
the salt storage area. It is usually caused by high
humidity or the wrong kind of salt. When the salt
bridges, an empty space forms between the
water and salt. Then salt will not dissolve in the
water to make brine.
1″–2″
If the brine 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.
Pencil
mark
Salt should be loose all the way to the bottom of
the tank. Take a broom handle or like tool, and
carefully push it down into the salt, working it up
and down. If the tool strikes a hard object (be
sure it’s not the bottom or sides of the tank), it’s
most likely a salt bridge. Carefully break the
bridge with the tool. Do not pound on the walls
of the tank.
Salt
Salt

Broom
handle
Water level
If the wrong kind of salt made the bridge, take it
out. Then fill the tank with nugget or pellet salt
only. In humid areas, it is best to fill with less salt,
more often to prevent a salt bridge from forming.
Cleaning the Injector and Screen
A clean injector and screen is needed for the
water softening system to work properly. This
small unit makes the suction to move brine from
the brine tank storage area to the resin tank
during regeneration. If it becomes plugged with
sand, dirt, etc., the water softening system will
not work and you will get hard water. This will
be evident by a high level of water in the brine
tank—over 4″ when the system is in service
mode.

•Clean and flush thoroughly.
•Check for damage.
•Reassemble injector and injector screen.

Care and cleaning of the water softening system.
Checking the Salt Storage Level and Refilling
Brine (salt dissolved in water) is needed for each
and every regeneration. The water for making
brine is metered into the salt storage area by
the water softening system valve and control.
However, you must keep the tank supplied
with salt.
CAUTION:
Water softening salt
with iron removing additives: Some salts
may have an additive to help the water
softening system handle iron in the water
supply. Although this additive may help to
keep the water softening system resin clean,
it may also release corrosive fumes that
weaken and shorten the life of some water
softening system parts. GE recommends
using only Diamond Crystal® Red•Out®
brand salt.
Use clean water softening salts only, at least
99.5% pure. NUGGET, PELLET or coarse SOLAR
salts are recommended. Do not use rock, block,
granulated or ice cream making salts. They
contain dirt and sediments, or mush and cake,
and will create maintenance problems.
Cleaning Iron Out of the Water Softening System
Your water softening system takes hardness
minerals (calcium and magnesium) out of
the water. Also, it can control some (see the
Specification Guidelines section) “clear water”
iron. 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 softening system will not
remove any iron that makes the water cloudy
or rusty as it comes from the faucet (called red
water iron). To take red water iron out of water,
or over the maximum of clear water iron,
an iron filter or other equipment is needed.
IMPORTANT: It is important to mix the resin bed
cleaner with water (following the manufacturer’s
instructions), pour it into the brinewell tube
(see page 5) and regenerate the softener
immediately. Do not pour the resin bed cleaner
in with the salt, as it will not be as effective in
cleaning the resin, and can cause damage to
the softener if it is left in the brine tank for an
extended period due to the corrosive gases
that are formed.
The control has an adjustable backwash
cycle. The backwash can be lengthened to
better flush the resin bed from high sediment
or iron situations. See the Advanced Control Setting
section or consult an installer.
GE recommends using only Diamond Crystal®
Red•Out® brand salts with Iron Fighter® additive
to help keep the resin bed clean of clear iron. If
your water supply has clear water iron, periodic
resin bed cleaning is needed. GE recommends
using Super Iron Out® brand resin bed cleaner
to thoroughly clean your resin bed if your iron
content is high. Clean the bed at least every six
months, or more often if iron appears in the soft
water between cleanings.
Also set LBS OF SALT and CAPACITY so the system
will regenerate about every 3 days. See page 13.

Troubleshooting Tips
Save time and money! Review the chart on these pages
first and you may not need to call for service.
NO SOFT WATER – Most Common Problems:
Check the following before calling for service:
•
•
Not enough salt—brine tank should be at least 1/3 full.
Bypass valve in “Bypass” position—flange on knobs should be in line with pipes
(see page 6).
•
•
Hardness setting too low. Check hardness setting and adjust. Verify hardness of supply
water—from local water company, water test or call the GE Answer Center.
Salt Bridge—salt solidifies above water level so that brine water is not in contact with
salt. See the Breaking a Salt Bridge section.
Problem
Possible Causes
What To Do
No soft water
Faucet or fixture where sample was
taken not plumbed to soft water.
NOTE: Be sure sample is from a faucet
that does not mix soft and hard water.
For example, a single lever kitchen faucet,
if the cold side is plumbed to hard water.
•
To conserve salt, the installer may have isolated some fixtures
(outside faucets, toilets, etc.) from soft water. From the outlet
of the water softening system, trace the water flow path,
in house plumbing. If soft water is not directed to a faucet
or fixture where wanted, consult a plumber.
No salt in the brine tank or

Manual Indexing for Each Regeneration
Errors
The control valve may be manually indexed to each
regeneration position as follows:
This system continuously monitors itself and displays an error
message if it detects something wrong.
1. Remove the control valve cover.
When an error is detected, the display shows the letters “Err”
with a number from 1 to 4. The table below lists Err numbers,
a description of each error, the cause of the error and the
solutions.
2. Press down on the top of the drive gear to disengage the
cam gear. (See Step 1 in Start-Up Rinsing Procedure
section.)
To clear the error from the display, press any button on the
control. If the error still exists, the control will display the error
message again after 30 seconds.
3. With the cam gear disengaged, rotate the cam gear
counterclockwise to the various positions, using the same
steps as the Start-Up Rinsing Procedure.
The control valve may also be operated in a fast mode for
testing the control. To activate the fast mode, follow Steps 1
and 2 above to disengage the cam gear. When the cam
gear is disengaged, it should be advanced slightly in a
counterclockwise direction.
The switch will then activate the motor to cause the cam gear
to advance through all the cycles in about 30 minutes. The
control will not recognize a fast mode as a regeneration.
Manual regenerations can be initiated only by pressing the
manual regeneration switch on the face of the control.

transformer or unplugging the power cord from the bottom
of the control.
2. Press down on the top of the drive gear to disengage the
cam gear.
3. With the cam gear disengaged, rotate the cam gear
counterclockwise to the REFILL position until the air check
fills with water, and water flows through the brine line into
the brine tank. Do not run for more than three minutes.
4. Press down on the drive gear, and rotate the cam gear
counterclockwise to the DRAW/RINSE position. Check that
water is being drawn from the brine tank. The water level
in the brine tank will recede very slowly. Observe the water
level for at least one minute. If the water level does not
recede, if it goes up or if air enters the transparent air
check chamber and the ball falls and seats, refer to
the Troubleshooting section in this manual.
