Installation Instructions
UNPACKING AND INSPECTION
Be sure to check the entire softener for ang
shipping damage or parts loss. Also note damage
to the shipping cartons. Contact the transportation
compang for all damage and loss claims. The
manufacturer is not responsible for damages
in transiL
Small parts needed to install the softener are
packaged either in a bag or on a cardboard
sheet. To avoid loss of the small parts, keep them
packaged until gou are readg to use them. Be sure
not to discard components hidden in packaging.
TOOLS AND MATERIALS REQUIRED
FOR INSTALLATION
• Pliers
Screwdriver
• Teflon tape
• Razor knife
Two adjustable wrenches
• Additional tools may be required if modification
to home plumbing is necessarg.
In and out fittings included with the softener are
!" NPT male adapters. You should maintain the
same, or larger, pipe size as the water supplg
pipe, up to the softener inlet and outlet. Then,
use the necessarg adapters to connect the water
supplg to the !" NPT male adapters.
Use the included bgpass valve to install the
softener. The bgpass valve allows gou to turn off
water to the softener for servicing, but still have
water in the house pipes. The in and out fittings
referred to above connect to the bgpass valve
with the included bgpass clips.
WHERE TO INSTALL THE SOFTENER
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 bg
the warrantg.
Do not install the softener where it would block
access to the water heater or access to the main
water shutoff.
Putthe softener in a place where water damage
is least likelg to occur if a leak develops. The
manufacturer will not repair or pag for water
damage.
A &20-volt electric outlet isneeded to plug in the
included transformer. The softener has a !0-foot
power cable. If the outlet is remote (up to !00
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.
If installing in an outside location, gou must
take the steps necessarg 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 warrants.
Keep the softener out of direct sunlight.
The sun's heat mag distort non-metallic
parts and mag damage the electronics.
• Use appropriate fitting/pipe material (i.e., copper,
brass, galvanized or CPVC) to connect the !" NTP
plastic adapters to the house plumbing.
• If additional drain hose is needed for valve and
salt tank drains, it can be ordered from GE Parts
at 800.626.2002, part number WS07X!0004.
If a rigid valve drain is needed to complg with
plumbing codes, gou can bug the parts needed
to connect a 1/2" copper tubing or plastic pipe
drain. See Step S.
Clean nugget or pellet water softener salt is
needed to fill the brine tank. See Step 11.
Installation Instructions
PLAN HOW YOU WILL INSTALL THE
SOFTENER
You must first decide how to run in and out pipes
to the softener. Look at the house main water pipe
at the point where gou will connect the softener.

Drain hose
• Locate the other end of the hose at a suitable
drain point (floor drain, sump, laundrg tub, etc.)
that terminates at the sewer. Check and complg
with local codes.
IMPORTANT: If more drain hose is needed, it
should be ordered from GE Parts at 800.6262002,
part number WS07X10004. The water softener will
not work if water cannot exit this hose during
recharge.
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 cgcles of recharge.
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."
• Slide softener back into position.
• Hake final connections to the bgpass valve and
snap clips into place.
Be sure the clips for the bypass valve and NPT
adapters snap into place. Pull on the bypass valve
and NPT adapters to make sure the parts are held
securely in place.
Installation Instructions
[_ CONNECT AND RUN THE VALVE
DRAIN HOSE ICONT.i
• Elevating the drain hose mag cause back
pressure that could reduce the brine draw during
recharge. 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 mag be raised to a
maximum height of 14'.

Installation Instructions
SANITIZING PROCEDURES
To complete the installation, do the following
sanitizing procedures.
Care is taken at the factorg to keep gour water
softener clean and sanitarg. Materials used to make
the softener will not infect or contaminate gour water
supplg 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: 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. (1V2tablespoons) of common
5.25% unscented household bleach (Clorox, Linco,
Bo Peep, White Sail, Eagle, etc.) into the brinewell.
Refer to illustration on page 5.
3. IMPORTANT: Press and hold for 3 seconds
the faceplate TOUCH/HOLD button to start an
immediate recharge. RECHARGE NOW begins to
flush in the displag. The bleach will be drawn
through the water softener, and out the drain.
This process takes approximatelg 2 hours.
4. If, after sanitization, water from the house
faucet tastes saltg 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.
NOTE: When the sanitizing recharge is over, all
remaining bleach is flushed from the conditioner
and gour house COLD water supplg is fullg soft
immediatelg. However, gour 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 onlg and mixed hot and cold
water will be fullg soft. If gou want totallg soft water
immediatelg, after the above recharge, drain the
water heater until the water runs cold.
AWARN ING: ,fgoudodrainthewater

About the water softener system, ge.com
Service
When the water softening system is providing
soft water, it is called "Service." During service,
hard water flows from the house main water pipe
into the water softening system. Inside the water
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
attracting and holding metals. Water without
hard minerals (soft water) flows from the water
softening system and to the house pipes.
After a period of time, the resin beads become
coated with hard minerals and theg have to be
cleaned. This cleaning is called recharge.
Recharge is started at 2:00 AH (factory setting)
by the water softening system control, and
consists of five stages or cgcles. These are FILL,
BRINING, BRINE RINSE, BACKWASH and FAST
RINSE,
Automatic Hard Water Bgpass During Recharge
For emergencg needs, hard water is available
to the home during the recharge cgcles.
Fill
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.
However, gou should avoid using HOT water
because the water heater will fill with the hard
water.
Backwash
During backwash, water travels up through
the resin tank at afast flow rate, flushing
accumulated iron, dirt and sediments
from the resin bed and to the drain.
Brining
During brining, brine travels from the salt storage
area into the resin tank. Brine isthe cleaning
agent needed to remove hard minerals from the
resin beads. The hard minerals and brine are
discharged to the drain.
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.
Fast Rinse
Backwash isfollowed by a fast flow of water
dawn 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.

Breaking a Salt Bridge
Sometimes, a hard crust or salt bridge forms in
the salt storage area. It is usuallu caused bu high
humiditu or the wrong kind of salt. When the salt
bridges, an empt Uspace forms between the
water and salt. Then salt will not dissolve in the
water to make brine.
If the brine tank is full of salt, it is hard to tell
if Uou have a salt bridge. Salt is loose on top, but
the bridge is under it. The following is the best
wau to check for a salt bridge.
Salt should be loose all the wag to the bottom of
the tank. Take a broom handle or liketool, and
carefullu 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 likelu a salt bridge. Carefullu break the
bridge with the tool. Do not pound on the walls
of the tank.
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 Nozzle and Venturi Assemblg
A clean nozzle and venturi is needed for the
water softening sgstern to work properlg. This
small unit makes the suction to move brine from
the salt storage area to the resin tank during
recharge. If it becomes plugged with sand, dirt,
etc., the water softening sustem will not work
and you will get hard water.
Toget to the nozzle and venturi, remove the
water softening system top cover Be sure the
water softening system is in service cycle (no
water pressure at nozzle and venturi). Then, while
holding the nozzle and venturi housing with one
hand, remove the cap. Lift out the screen support
and screen, then the nozzle and venturi. Wash
and rinse the parts in warm water until clean. If
needed, use a small brush to remove iron or dirt.
Also check and clean the gasket.
NOTE:Some models have a small flow plug
located in the nozzle and venturi, and/or a small
cone shaped screen in the housing. Be sure to
check and clean these parts, if your model is
so equipped.
Carefully replace all parts inthe correct
order. Lightly lubricate the o-ring seal with clean
silicone grease or petroleum jelly and place in
position. Install and tighten the cap, bg hand
onlg. Do not overtighten the cap.

Normal Operation, Timer Displag
During normal operation, the present time of day and AM or PH show in the control display
area. When the demand computer determines a regeneration isneeded, RECHARGE TONIGHT
begins to flash in the display, along with the present time. RECHARGE TONIGHT flashes until
the next regeneration start time, then changes to RECHARGE NOW, which flashes until the
regeneration is oven The displag also shows the current cgcle in the regeneration process.
When the valve is in transition between cgcles, both indicators flash.
Feature: Optional Recharge Controls
Sometimes, a manually started regeneration (recharge) may be desired or needed,
Two examples:
::Ji::You have used more water than usual (house guests, extra washing, etc,) and gou may run out
of soft water before the next regeneration.
_ You did not refill the storage tank with salt before it was all gone.
Use one of the following features to start a regeneration immediately, or at the next preset
regeneration start time.
RECHARGE NOW
Pressand hold theTOUCHor HOLDbutton until RECHARGENOW starts to flash in the control
displag area.Thewater softening sgstem begins an immediate regeneration and,when over in

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 recharge. The water for making brine
is metered into the salt storage area by the
water softening system valve and control.
However, gou must keep the tank supplied
with salt.
When to refill with salt: Check the salt level a
few weeks after you install the water softening
system and ever Uweek after that. Refill when
the brine tank isfrom !/3 to !/2 full. Never allow
the water softening system to use all the salt
before you refill it. Without salt, you will soon
have hard water.
Cleaning Iron Out of the Water Softening Sgstem
Use clean water softening salts only, at least
99.5% pure. NUGGET,PELLETor 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.
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 maUalso 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.
Your water softening system takes hardness
minerals (calcium and magnesium) out of
the water. Also, it can control some (seethe
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 nat
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.
GErecommends using only Diamond Crustal®
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. GErecommends
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.
IMPORTANT:It is important to mix the resin bed
cleaner with water (following the manufacturer's
instructions), pour it into the brinewell tube
(seepage 5) and recharge 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 isleft in the brine tank for an
extended period due to the corrosive gases
that are formed.

Troubleshooting Tips
Save time and money! Review the chart on this page first
and you may not need to call for service.
NO SOFTWATER- Most Common Problems:
Check the following before coiling for service:
• Not enough saltishould be at least 1/3 full.
• Bypass valve in "Bypass" positioniknob should be in the "OUT" (service)position.
• Hardness setting too low. Check hardness setting and adjust. Verify hardness of supply
water--from local water company, water test or call the GEAnswer Center.
• Salt BridgeJsalt solidifies above water level so that brine water is not in contact with
salt. See the Breaking a Salt Bridge section.
