Installation Instructions

Water Softening

System

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 regeneration 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 12 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. These products may contain dirt and sediments, or mush and cake, and will create maintenance problems.

■ Keep the brine tank 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 install in direct sunlight. Excessive sun or

heat may cause distortion or other damage to non-metallic parts. Do not attempt to treat water over 100°F.

■ Properly ground the system 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.)

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.

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 100°F.

Installation Instructions

UNPACKING AND INSPECTION

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.

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.

TOOLS AND MATERIALS REQUIRED FOR INSTALLATION

• Teflon tape

• 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.

• 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.

• 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.

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 the inlet and outlet 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.

OPTIONAL 3-VALVE BYPASS INSTALLATION ILLUSTRATION

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.

To return to the conditioned water or service position, rotate the handles counterclockwise so they are parallel to the flow path of the inlet and outlet water stream, as shown below.

Installation Instructions

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.

• 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.

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 simultaneously. It is not necessary to lubricate or use sealant on the rubber gaskets or union nuts.

• Insert copper adapters through union nuts. Place the rubber gaskets into the union nuts and assemble to bypass valve. It is not necessary to lubricate or use sealant on rubber gasket or union nuts.

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 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.

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.

• Support inlet and outlet plumbing in some manner

(use pipe hangers or clamps) to keep the weight

off of the valve fittings.

• Slide softener back into position.

• Make final connections to the bypass valve.

Installation Instructions

CONNECT AND RUN THE VALVE DRAIN HOSE

• Check that drain port on valve body has white

tape on it. If not, apply Teflon Tape to threads prior to installing the valve drain fitting.

• Connect valve drain fitting to valve drain port.

Tighten connection with a wrench.

• Connect 1/2″ diameter drain hose (not provided)

to the valve drain fitting. Tighten connections with wrench.

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.

• 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.

• 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′.

INSTALL GROUNDING WIRE AND CLAMPS

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.

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.

Installation Instructions

INSTALL THE BRINE TANK OVERFLOW AND HOSE

• Connect overflow drain hose to fitting on side of brine tank.

• 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.

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).

RUN THE WATER

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.

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.

Advance the gear in the counterclockwise direction only. Damage will occur if advanced in the opposite direction.

FILL BRINE TANK

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.

Once water begins to flow into the tank, fill the brine tank with a minimum of 80 lbs. of salt pellets.

PURGE THE SYSTEM

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.

Outlet

Inlet

INJECTOR SELECTION

• The injector is critical to the proper flow through the resin tank during the regeneration cycle. The injector supplied with the unit from the factory is applicable to installations with supply water pressure up to 70 psi.

• If supply water pressure is greater than 70 psi, injector assembly WS15X10059 should be installed.

Installation Instructions

ADVANCE CONTROL VALVE TO SERVICE POSITION

After the ten-minute refill time, manually advance the control valve to the service position.

CONNECT TO ELECTRICAL POWER

• The softener works on 12 volt60Hz electric power. The included transformer changes standard 120-volt AC house power to 12 volts DC. Connect transformer to control panel. Plug is located on the bottom left of the control panel. Plug

the transformer into a 120volt outlet only. Be sure the

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

INSTALL 9V BATTERY FOR BATTERY BACKUP FEATURE

(CONT.)

To install a battery:

1. Remove the control valve cover.

2. The battery pocket is located in the upper left

corner of the control as shown.

3. Connect the battery, matching up negative and positive posts.

4. Insert battery into holder located on the back of the control panel. Make sure terminal wires are routed away from the valve gears.

Injector

Injector cap

INSTALL 9V BATTERY FOR BATTERY BACKUP FEATURE

Your softening system has a battery backup feature that allows the control to continue monitoring water flow and maintain the proper time of day during short power outages. The control uses a standard 9-volt battery (not supplied).

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.

SALT PER REGEN AND CAPACITY

These two settings are required to provide the most efficient operation of the system in your installation.

Salt efficiency is improved by regenerating part of the capacity. For example, the GNPR40 has 37,100 grains of capacity. It is more efficient to regenerate 20,000 grains of capacity more frequently than waiting and regenerating the complete 37,100 grains.

Both SALT PER REGEN and CAPACITY are determined based on the chart on page 13.

FOR CALIFORNIA INSTALLATIONS:

• California regulations require the control setting

to yield 4,000 grains of capacity per pound of salt. To meet these requirements, the SALT PER REGEN and CAPACITY must be set no higher than indicated below:

Installation Instructions

TIME OF REGENERATION

The system has a default setting of 2:00 a.m.

To change:

• Use the UP or DOWN button to select a new time for regeneration.

• Use procedure in SET PRESENT TIME OF DAY.

• Press the SET button to accept.

TOTAL WATER HARDNESS

Water hardness is the hardness of the supply water to the house in grains per gallon. The system has a default setting of 25 grains/gallon.

A water test should be performed at the time of installation to determine your water hardness (grains/gallon). 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. If your report shows hardness in parts per million (ppm), simply divide by 17.1 to get the equivalent number of grains per gallon.

To change:

• Use the UP or DOWN button to select total water hardness.

• Press the SET button.

• Change the digits by using the UP , DOWN or LEFT button.

• Press the SET button to accept.

Installation Instructions

SALT PER REGEN AND CAPACITY (CONT.)

NOTE: Both SALT PER REGEN and CAPACITY inputs must be based on the SYSTEM CAPACITY INPUTS CHART.

How to determine correct salt dosage and capacity:

The correct salt dosage and capacity are determined based on the family size and water hardness. Use the 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

240 gallons/day x 20 grains = 4,800 grains/day

• Water softener should be set to regenerate every 5 days.

Req Capacity = 5 days x 4,800 grains/day = 24,000

• Use SYSTEM CAPACITY INPUT table to select capacity and determine lbs of salt per regeneration.

For GNPR40 use setting at 24,000 grains.

• Program the control:

Capacity: 24,000 grains

Lbs of Salt: 7.0

If water supply has a high level of sediment or iron, set system to regenerate every 3 days:

• Use the UP or DOWN button to select SALT PER REGEN.

• Press the SET button.

• Use the UP , DOWN and LEFT buttons to select SALT PER REGEN amount .

• Press the SET button to accept.

• Use the UP or DOWN button to select CAPACITY.

• Press the SET button.

• Use the UP , DOWN and LEFT buttons to select correct capacity.

• Press the SET button to accept.

Installation Instructions

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.

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.

NOTE: The second regeneration will begin 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.

REGEN button

NORMAL OPERATION

The control will cycle between TIME OF DAY and CAPACITY about every 10 seconds, as indicated by the green indicator light .

Capacity in Normal Operation mode is the gallons of water available until the next regeneration cycle.

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.

ERROR CODES

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.

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.

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.

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.

• Harmonic sound – As the valve transitions between cycles in regeneration, a high-pitched harmonic noise may be heard for a few seconds.

• 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.

SPECIFICATIONS/DIMENSIONS

Installation Instructions

These systems conform to WQA NSF/ANSI 44 for the specific capacity claims as verified and substantiated by test data. * Testing was performed using pellet grade sodium chloride as the regenerant salt . ** Efficiency rating is valid only at the lowest stated salt dosage. These softeners were efficiency rated according to

WQA NSF/ANSI 44.

*** Extent of iron removal may vary with conditions. The capacity to reduce clear water iron is substantiated by WQA

test data. State of Wisconsin requires additional treatment if water supply contains greater than 5 ppm clear water iron. Use of Diamond Crystal

Red•Out®or Super Iron Out®will improve iron removal. Refer to Cleaning Iron Out

of the Water Softening System section.

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 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.

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 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.

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 regeneration. The regeneration cycle 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 regeneration cycles.

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

Automatic Hard Water Bypass During Regeneration

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 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.

TO CLEAN:

•Put system in Bypass mode and relieve water

pressure.

•Remove injector screen (a flat-head screwdriver

is required).

•Remove injector cap and injector (needle nose

pliers are required).

•Clean and flush thoroughly.

•Check for damage.

•Reassemble injector and injector screen.

•To check proper operation, see page 30,

Checking the Brine Draw and Refill Function.

•Initiate REGEN cycle to restore resin bed.

A back-to-back regeneration is suggested. Excess water in the brine tank will be removed.

Care and cleaning of the water softening system.

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.

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 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.

Also set LBS OF SALT and CAPACITY so the system will regenerate about every 3 days. See page 13.

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.

5. When water is being drawn from the brine tank, press down on the drive gear and rotate the cam gear counterclockwise to just before the SERVICE position. Connect power to the control and allow the motor to drive the cam gear to the SERVICE position. The motor will stop. Run cold water from a nearby faucet until the water is clear and soft.

Checking the brine draw and refill function.

In rare instances, the turbine wheel of the water meter can collect small particles of oxidized iron, eventually preventing the wheel from turning.

If the flow indicator light does not blink when conditioned water is flowing from the unit, it is an indication that the turbine wheel is not turning.

1. Disconnect electrical power to the unit.

2. Shut off the water supply or put the bypass valve(s) into the

BYPASS position.

3. Relieve resin tank pressure: A. Remove control valve cover. B. Press down on the top of the drive gear to disengage the

cam gear.

C. With the cam gear disengaged, rotate the cam gear

counterclockwise to the BACKWASH position.

Check that there is no water flow through the drain line before performing service or preventative maintenance.

4. Disconnect the water conditioner from the plumbing.

5. Using a needle-nose pliers, remove the outer gland and

the turbine wheel from the outlet of the valve. Generally, it will not be necessary to remove the inner gland.

6. Clean all iron deposits and/or debris off the turbine wheel. Excessive accumulation of iron may be removed from the components with a solution of sodium hydrosulfite (or sodium disulfite). Rinse the components thoroughly in clean water after using the iron removal solution.

7. Flush accumulated iron deposits and/or debris from the inside of the valve outlet.

8. Reinstall the turbine wheel into the outlet side of the valve, being certain that the turbine wheel shaft is carefully seated into the bearing of the inner gland.

9. Carefully reinstall the outer gland into the outlet side of the valve. Check turbine rotation.

10. Reconnect the water conditioner to the plumbing and follow Initial Start-Up section.

11. Open the downstream faucet (conditioned water) and check to be certain that the flow indicator (colon) is blinking.
