Water Softening

System

System tested and certified by NSF International against NSF/ANSI Standard 44 for the chemical reduction claims specified on the performance data sheet .

Sistema probado y certificado por NSF International contra norma 44 de NSF/ANSI para las afirmaciones de reducción de los productos químicos especificadas en la hoja de datos de funcionamiento.

IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING.

SAFETY PRECAUTIONS

■ Check and comply with your state and local codes.

You must follow these guidelines.

■ Use care when handling the water softening

system. Do not turn upside down, drop, drag or set on sharp protrusions.

■ Water softening systems using sodium chloride

(salt) for recharge add sodium to the water.

Persons on sodium restricted diets should consider the added sodium as part of their overall intake. Potassium chloride can be used as an alternative to sodium chloride in your softener.

■

The water softening system works on 24 volt-60 Hz electrical power only. Be sure to use only the

included transformer.

■ Transformer must be plugged into an indoor

120 volt, grounded outlet only.

■ 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.

■ Keep the salt hole cover in place on the softener

unless servicing the unit or refilling with salt .

WARNING: Do not use with water that

is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

READ AND FOLLOW THIS SAFETY INFORMATION CAREFULLY.

SAVE THESE INSTRUCTIONS

PROPER INSTALLATION

■ Install or store where it will not be exposed to

temperatures below freezing or exposed to any type of weather. Water freezing in the system will break it. Do not attempt to treat water over 100°F.

■ Do not install in direct sunlight. Excessive sun or

heat may cause distortion or other damage to non-metallic parts.

■ Properly ground to conform with all governing

codes and ordinances.

■ Use only lead-free solder and flux for all

sweat-solder connections, as required by state and federal codes.

■

The water softening system requires a minimum water flow of three gallons per minute at the inlet. Maximum allowable inlet water pressure is 125 psi. If daytime pressure is over 80 psi, nighttime pressure may exceed the maximum. Use a pressure reducing valve to reduce the flow if necessary.

■

Softener resins may degrade in the presence of chlorine above 2 ppm. If you have chlorine in excess of this amount, you may experience reduced life of the resin. In these conditions, you may wish to consider purchasing a GE point-of-entry household filtration system with a chlorine reducing filter.

WARNING: Discard all unused parts

and packaging material after installation. Small parts remaining after the installation could be a choke hazard.

This water softening system must be properly installed and located in accordance with the Installation Instructions before it is used.

For your safety, the information in this manual must be followed to minimize the risk of electric shock, property damage or personal injury.

IMPORTANT INSTALLATION RECOMMENDATIONS

(CONT.)

• Use care when handling the softener. Do not turn upside down, drop, drag or set on sharp protrusions.

• Maximum allowable inlet water pressure is 125 psi. If daytime pressure is over 80 psi, nighttime pressure may exceed the maximum. Use a pressure reducing valve if necessary. (Adding a pressure reducing valve may reduce the flow.)

• The softener works on 24 volt-60 Hz electrical power only. Be sure to use the included transformer. Be sure the electric outlet and transformer are in an inside location to protect from moisture.

• See Where to Install the Softener section for more details.

WARNING: Do not use with water

that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. The water should be tested periodically to verify that the system is performing satisfactorily.

• Small parts remaining after the installation could be a choke hazard. Discard safely.

IMPORTANT INSTALLATION RECOMMENDATIONS

• In the Commonwealth of Massachusetts,

Plumbing Code 248 CMR shall be adhered to. Consult with your licensed plumber.

• Use only lead-free solder and flux for all sweatsolder connections, as required by state and federal codes.

• Connect the softener to the main water supply pipe before or ahead of the water heater.

DO NOT RUN HOT WATER THROUGH THE SOFTENER. Temperature of water passing

through the softener must be less than 120°F.

Installation Instructions

UNPACKING AND INSPECTION

Be sure to check the entire softener for any shipping damage or parts loss. 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.

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 you are ready 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 necessary.

• In and out fittings included with the softener

are 1″ NPT male 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″ NPT male 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 in the house pipes. The NPT male adapters referred to above connect to the bypass valve with the included plastic clips.

• Use appropriate fitting/pipe material (i.e., copper,

brass, galvanized or CPVC) to connect the 1″ 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 WS07X10004.

• 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. See Step 4.

• Clean nugget or pellet water softener salt is

needed to fill the brine tank. See Step 8.

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 by

the warranty.

• 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.

• 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.

• 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.

• Keep the softener out of direct sunlight. The sun’s heat may distort non-metallic parts and may damage the electronics.

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 you will connect the softener. Is the pipe soldered copper, glued plastic or threaded galvanized? What is the pipe size?

WARNING: Use only lead-free solder and

flux to prevent lead poisoning.

See Typical Installation Illustration. Use this as a guide when planning your particular installation. Be sure

to direct the incoming hard water supply to the softener valve inlet fitting. The valve is marked IN and OUT.

PLUMB “IN” AND “OUT” PIPES TO AND FROM SOFTENER

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 left, use a plumbing crossover as shown in Typical Installation Illustration. If house water flows up from the floor level, turn the bypass valve upside down as shown.

• With the softener in place, determine the correct length of piping required to connect the household plumbing to the NPT male adapter.

• Remove softener from installation space.

• If making a soldered copper installation, do all

sweat soldering before connecting pipes to the NPT adapters and bypass valve. Torch heat will

damage plastic parts.

• When turning threaded pipe fittings onto plastic fittings, use care not to cross-thread.

• Use Teflon Tape on all external pipe threads.

• Support inlet and outlet plumbing in some manner (use pipe hangers) to keep the weight off of the

valve fittings.

• Slide softener back into position.

• Make final connections to the bypass 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.

CONNECT AND RUN THE VALVE DRAIN HOSE

• Use the provided drain hose (20′ length included) to attach to the valve drain fitting. To keep water pressure from blowing the hose off, use supplied spring clamp to secure in place. Cut the necessary length and use the remainder in Step 5.

• 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.

IMPORTANT: If more drain hose is needed, it

should be ordered from GE Parts at 800.626.2002, 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 cycles 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.”

Installation Instructions

CONNECT AND RUN THE VALVE DRAIN HOSE

(CONT.)

• Elevating the drain hose may 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 may be raised to a maximum height of 14′.

CONNECTING A RIGID VALVE DRAIN TUBE

To adapt a copper drain tube to the softener, use a hacksaw to cut the barbed end from the drain fitting as shown. Rotate the drain fitting so the cutting blade clears the valve housing to prevent damage to valve

. Buy a compression fitting (1/4″

female pipe thread x 1/2″ O.D. tube) and needed tubing from your local hardware store.

INSTALL THE BRINE TANK OVERFLOW FITTINGS AND HOSE

• Insert the rubber grommet into the 3/4″ diameter hole in the brine tank sidewall as shown.

• Push the end of the hose adapter elbow into the grommet as shown.

• Attach a length of hose (use remaining hose from Step 4) to the hose adapter elbow. Use a hose clamp to hold it in place.

• 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.

INSTALL GROUNDING CLAMP

DANGER: Failure to properly attach

ground clamp could result in electrical shock.

If plumbing is metal, to maintain electrical ground continuity in the house cold water piping, install the included ground clamp as shown.

• Clean pipe with emery paper in the area where the clamp is to be installed.

• Install grounding clamps as shown, making sure clamps fit freely around pipe.

• Make sure lock washer is in place.

• Handtighten screw, then one more full turn with screwdriver.

NOTE: When replacing an existing softener, also replace grounding clamps. If removing softener completely, hard-plumb the water line with same type of pipes as the original to assure plumbing integrity and ground continuity over the life of the home.

Installation Instructions

FLUSH PIPES, EXPEL AIR FROM SOFTENER AND TEST YOUR INSTALLATION FOR WATER LEAKS

(CONT.)

• Place bypass valve in the “service” position

EXACTLY as follows. KEEP SOFT WATER FAUCETS OPEN.

SLOWLY pull or slide the valve stem (out) toward the service position, pausing several times to allow the softener to pressurize slowly.

• After about 3 minutes, open a HOT water faucet

for 1 minute, or until all air is expelled, then close. NOTE: If water appears cloudy or has salty

taste, allow to run for several more minutes, or until clear.

• Close all water faucets.

• Check your plumbing work for leaks and fix

right away if any are found. Be sure to observe previous caution notes.

• Turn on the gas or electric supply to the water

heater. Light the pilot , if applicable.

ADD WATER AND SALT TO THE BRINE TANK

• Lift the salt hole cover. Add about 3 gallons of water into the tank. Do not add into the brinewell.

• Fill tank with NUGGET, PELLET or coarse SOLAR water softener salt with a purity of 99.5% or higher. Do not use rock, block, granulated and ice cream-making salts, or salt with iron-removing additives (except for Diamond Crystal

Red•Out

brand salt). Maximum salt storage capacity is approximately 200 lbs. Keep the salt hole cover closed unless servicing the unit or refilling with salt.

NOTE: If the softener is installed in a humid basement or other damp area, it is better to fill the tank with less salt, more frequently. Eighty to 100 lbs. of salt will last for several months, depending on water hardness, family size and water softening system model.

FLUSH PIPES, EXPEL AIR FROM SOFTENER AND TEST YOUR INSTALLATION FOR WATER LEAKS

CAUTION: To avoid water or air

pressure damage to softener inner parts, be sure to do the following steps in exact order.

• Fully open 2 cold soft water faucets nearby

the softener.

• Place bypass valve in “bypass” position by

pushing the stem inward.

• Fully open the house main water pipe shutoff

valve. Observe a steady flow from both faucets opened above.

Installation Instructions

CONNECT TO ELECTRICAL POWER

To gain access to the transformer/power cord assembly, remove the salt hole cover from the softener. Unclip the tabs on the rear of the top cover and rotate the cover upward to remove. DO NOT PULL OR DISCONNECT WIRING.

• The softener works on 24 volt-60Hz electric power. The included transformer changes standard 120-volt AC house power to 24 volts.

Plug the transformer into a 120-volt outlet only.

Be sure the outlet is always live so it can not be switched off by mistake.

• Replace the top cover.

• Replace the salt hole cover.

NOTE: If there is clear water iron in your water supply, you will need to increase the hardness setting by 5 for each 1 ppm of clear water iron in your water supply.

You can get the grains per gallon (gpg) hardness of your water supply from a water analysis laboratory. If you are on a municipal supply, call your local water department. Or call Legend Technical Services, an independent laboratory, to request a water hardness test kit at 1.800.949.8220, Option 4. If your report shows hardness in parts per million (ppm) or milligrams per liter (mg/l), simply divide by 17.1 to get the equivalent number of grains per gallon.

SET RECHARGE (STARTING) TIME

1. Press the MODE button

until arrow points to

RECHARGE TIME.

NOTE: A flashing 2:00 AM

(factory default) should show in the display. This is a good time for recharge to start (takes about 2 hours) in most households because water is not in use. HARD WATER is bypassed to house faucets during recharge.

3. Press UP or DOWN button to set the SALT LEVEL to correspond to level on yellow indicator in brine tank.

NOTE: Each press of a button changes the level by increments of 0.5 up to 8.0. As the number increases, the salt level bars increase on each whole number. Lowering the salt level below zero turns the

SALT LEVEL indicator OFF.

4. Press the MODE button to

accept. The display shows the present time of day and DAYS

TO EMPTY. RECHARGE TONIGHT

may appear if unit is new.

DAYS TO EMPTY

The words DAYS TO EMPTY and a number are shown in the lower half of the display. This information is shown in the normal run display. This is to inform the user of the number of days before the salt level in the brine tank reaches Level 0. There will be salt left in the salt tank, but it may not be sufficient to fully recharge the system. Salt should be added at this time to avoid hard water. The value is updated daily and whenever the SALT LEVEL value is changed.

NOTE: For the first several weeks of operation, the DAYS TO EMPTY may provide erratic operation. For

example, the blue indicator light may flash, showing that more salt is required when the actual salt level in the tank is well above the Level 0. In some cases, the DAYS TO EMPTY may even increase over a several week period.

It takes a couple of months for the water softener to learn your water usage pattern. Once it does this, it will accurately determine actual salt usage pattern. During this first period, check salt level when blue indicator light flashes. If the salt level in the tank is at Level 1 or above, allow system to run. Be sure to reset your salt level indicator each time you add salt to the system.

OPTIONAL CONTROL SETTINGS

The controller display has several options and features.

LOW SALT ALARM

The LOW SALT ALARM, when enabled, will sound the beeper when the DAYS TO EMPTY value is 15 days or less. To change this setting, press and hold the MODE button for 3 seconds. ON (factory default) or OFF will flash in the display. Press the UP

or DOWN buttons to toggle this feature ON or OFF. Press the MODE button to accept, and the display will move to SALT EFFICIENCY.

SALT EFFICIENCY

When the SALT EFFICIENCY feature is ON, the unit will operate at a salt efficiency of 4000 grains of hardness removed per pound of salt. This mode of operation is the most efficient setting for salt usage, because the system will tend to recharge more often, with less salt usage. Turning the feature OFF will tend to lengthen the time between recharge cycles, which will provide the most efficient usage of water, but may use more salt. The degree of difference between these two cycles is highly dependent on the water usage and hardness at a particular installation.

If you have very hard water, and you find your system is regenerating every 1–2 days, turn the SALT EFFICIENCY to OFF to lengthen the time between regenerations.

NOTE: California Regulations require this feature to be ON for installations in California.

To change the setting, press the UP or DOWN buttons to toggle the feature ON or OFF. Press the

MODE button to accept. The display will move to SYSTEM/ELECTRONIC DIAGNOSTICS.

SYSTEM/ELECTRONIC DIAGNOSTICS

This display contains system diagnostics information to assist in troubleshooting problems with the system. See page 17 for details. Press the MODE button to return to the normal run display.

SIGNALS

LOST TIME SIGNAL

If time is lost on the display due to power interruption, the blue indicator light will flash 4 times every second, until the present time of day is entered.

LOW SALT SIGNAL

When the DAYS TO EMPTY drops to 15, the blue indicator light and DAYS TO EMPTY in the display will flash every second and the alarm will beep every 30 seconds (from 8:00 AM to 8:00 PM), to notify the user that the unit is running low on salt. As soon as any button is pressed, the alarm will stop beeping. The blue indicator light and DAYS TO EMPTY will continue to flash. Once salt is added to the brine tank and the SALT LEVEL is reset, the

DAYS TO EMPTY will be reset.

ERROR SIGNALS

If there is an error code detected, the blue indicator light will flash 4 times every second, the display will flash Err and the alarm will beep every 30 seconds (from 8:00 AM to 8:00 PM) to signal that the softener requires service. The alarm can be turned off by pressing any button, but the blue indicator light and display will continue to flash.

See page 17 for information to assist in troubleshooting error codes. Once the problem is corrected, disconnect the transformer from the wall outlet momentarily, and plug it back in. The normal display will appear. The motor may run for several minutes, as the unit resets. If the problem is not corrected, the error code will reappear in 6 minutes.

BLUE INDICATOR LIGHT

Steady blue light indicates that the unit is working correctly. The light flashes when the unit needs attention from the user.

• Light flashes and DAYS TO EMPTY flashes—check salt level and add salt as required.

• Light flashes and Err is in the display—electrical problem with system—see page 17.

• Light will also flash when power to the unit has been interrupted. Check the PRESENT TIME setting.

SANITIZING PROCEDURES

To complete the installation, do the following 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: 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. (1

⁄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.

3. IMPORTANT: Press and hold for 3 seconds the faceplate RECHARGE button to start an immediate recharge. RECHARGE begins to flash in the display. The bleach will be drawn through the

water softener, and out the drain. This process takes approximately 2 hours.

4. If, after sanitization, water from the house 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.

NOTE: When the sanitizing recharge 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 recharge, drain the water heater until the water runs cold.

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.

About the water softener system.

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 they have to be cleaned. This cleaning is called recharge. Recharge is started at 2:00 AM (factory setting) by the water softening system control, and consists of five stages or cycles. These are FILL,

BRINING, BRINE RINSE, BACKWASH and FAST RINSE.

For emergency needs, hard water is available to the home during the recharge cycles.

However, you should avoid using HOT water because the water heater will fill with the hard water.

Automatic Hard Water Bypass During Recharge

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.

Brining

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.

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.

Backwash

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.

Fast Rinse

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.

Breaking a Salt Bridge

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.

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.

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.

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.

A clean nozzle and venturi is needed for the water softening system to work properly. 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 system will not work and you will get hard water.

To get 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 in the correct order. Lightly lubricate the o-ring seal with clean silicone grease or petroleum jelly and place in position. Install and tighten the cap, by hand

only. Do not overtighten the cap.

About the water softener system.

During normal operation, the present time of day and AM or PM and DAYS TO EMPTY show in the control display area. When the demand computer determines a recharge is needed, RECHARGE TONIGHT begins to flash in the display along with the present time. RECHARGE TONIGHT flashes until the next recharge start time, then changes to RECHARGE, which flashes until the recharge is over.

Normal Operation, Control Displays

Sometimes, a manually started recharge may be desired or needed. Two examples:

■ You have used more water than usual (house

guests, extra washing, etc.) and you may run out of soft water before the next recharge.

■ The system ran out of salt.

Use one of the following features to start a recharge immediately, or at the next preset recharge start time.

RECHARGE TONIGHT

Touch (do not hold) the RECHARGE button. RECHARGE TONIGHT flashes in the control

display area. A recharge will occur at the next preset recharge start time. If you decide to cancel this recharge, touch the same button once more.

RECHARGE

Press and hold the RECHARGE button until RECHARGE starts to flash in the control display

area. The water softening system begins an immediate recharge and, when over in about two hours, you will have a new supply of soft water. Once started, you cannot cancel this recharge.

Feature: Optional Recharge Controls

Feature: Memory

If electrical power to the water softening system is interrupted, the control display is blank, and the blue indicator light is off, but the control keeps correct time for about 6 hours. When power is restored, you have to reset the present time only if the display and blue indicator light are flashing. All other settings are maintained and never require resetting unless a change is desired.

If the time is flashing after a long power outage, the water softening system continues to work as it should to provide you with soft water. However, recharge may occur at the wrong time of day until you reset the control to the correct time of day.

The control computer has a self-diagnostic function for the electrical system (except input power and water meter). The computer monitors the electronic components and circuits for correct operation. If a malfunction occurs, an error code appears in the control display.

The chart on Error Codes shows the error codes that could appear and possible reasons for each code. See Manually Initiated Electronics Diagnostics to further isolate the defect.

Service: Electronic Demand Time Features and Service

If you are not getting soft water, and an error code is not displayed, use the procedures below to find the problem. First make the following visual checks.

VISUAL CHECKS:

1. Is there electrical power to the outlet the water

softening system transformer is plugged into?

2. Is there sufficient salt in the storage tank?

3. Is the softener bypass valve directing water

for soft water service?

4. Is the valve drain hose open to the drain, not more than 8′ above the softener, and unobstructed? If hose is above 8′, see page 8, step 4.

If you do not find a problem with the visual checks, continue below.

• Position Switch Operation –

– Closed – valve rotating to next position

– Open – valve in position, service, fill, brine, etc.

• Water Meter – Indicates whether water is flowing

through valve.

– 000 indicates no water is flowing through the valve – Open nearby soft water faucet – 000 to 141 (continual) shows water is flowing. Display

repeats for each gallon of water passing through the meter. Control will beep at every gallon.

– If there is no reading in the display, with faucet open,

check the sensor. Pull the sensor from the valve outlet port, and pass a small magnet in front of the sensor. Counter should index in the display. If counter does not index, check to make sure harness is connected to board properly. If there is a reading in the display, there may be a problem associated with the turbine. Turn off water supply, close the bypass valve and disconnect bypass valve from body. Check turbine for binding or restriction due to debris. If this does not correct the problem, the Timer, Sensor or Turbine may require replacement.

NOTE: The control display must show a steady

time (not flashing).

1. Press the RECHARGE button and hold in for three seconds. RECHARGE begins to flash as the water softening system enters the fill cycle of recharge. Remove the brinewell cover and, using a flashlight , observe fill water entering the brine tank. If water does not enter the tank, look for an obstructed nozzle, venturi, fill flow plug or brine tubing. See Care and Cleaning of the Water Softener System section.

2. After observing fill, press the RECHARGE button to move the water softening system into brining. A slow flow of water to the drain will begin. Verify brine draw from the brine tank by shining a flashlight into the brinewell and observing a noticeable drop in the liquid level over an extended period of time.

NOTE: Be sure a salt bridge is not preventing water from contacting salt. See Care and

cleaning of the water softening system section.

If the water softening system does not draw brine, check:

■ nozzle and/or venturi dirty or defective.

■ defective nozzle and venturi seal.

■ nozzle and venturi not seated properly

on gasket.

■ other inner valve defect (rotor seal, rotor and

disc, wave washer, etc.).

■ restricted drain (check drain fitting and

hose).

NOTE: If water system pressure is low, an elevated drain hose may cause back pressure, stopping brine draw.

3. Again, press the RECHARGE button to move the water softening system into backwash. Look for a fast flow of water from the drain hose. A slow flow indicates a plugged top distributor, backwash flow plug or drain hose.

4. Press the RECHARGE button to move the water softening system into fast rinse. Again look for a fast drain flow. Allow the water softening system to rinse for a few minutes to flush out any brine that may remain in the resin tank from the brining cycle test.

5. To return the water softening system to service, press the RECHARGE button.

Service: Manually Advance Recharge Check

Care and cleaning of the water softening system.

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, you must keep the tank supplied with salt.

When to refill with salt: If the blue indicator light

and DAYS TO EMPTY are flashing, there is less than 15 days supply of salt. Refill with salt. In humid areas it is best to refill with less salt and more often, to avoid the forming of a salt bridge (see page 15). After adding salt, remember to reset the SALT LEVEL in the control (see page 11). Never allow the salt level to drop below zero on the yellow indicator before you refill it. Without enough salt, you will soon have hard water.

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.

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.

Checking the Salt Storage Level and Refilling

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.

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.

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 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 is left in the brine tank for an extended period due to the corrosive gases that are formed.
