• Professional Installation Required: Installation requires shutting water off to home, cutting home water supply pipe and connecting piping and fittings. Specialized tools and skills are required.

SECTION 1: BEFORE INSTALLATION

Congratulations! We believe your purchase of this water softener will prove to be a very wise choice. When properly installed, operated, and maintained, your new water softener will provide years of dependable service. Before starting the installation, please read this entire manual for an overview, and then follow the installation instructions. Failure to follow the instructions will void the warranty.

Inspecting And Handling Your Water Softener:

I nspect shipping carton and the equipment for shipping damage. If damaged, notify the transportation company and request a damage inspection.

Handle the equipment with care. Damage can result if dropped or if the brine tank is set on sharp, uneven projections on the fl oor. When handling, do not turn the water softener unit upside down or on its side to help prevent media from entering valve and being discharged downstream.

Make Sure Your Water Has Been Thoroughly Tested:

An analysis of your water should be made prior to the selection of your water softener. You can typically get this service through your place of purchase, which may require sending a sample to the factory for analysis and recommendations. Enter your analysis below for your permanent record.

Analysis of Your Water:

Hardness gpg Tannins (Humic Acid) ppm

Iron (Fe) ppm Hydrogen Sulfi de (H2S) ppm

Manganese (Mn) ppm Other ppm pH ppm

Other ppm

The test for Hydrogen sulfi de (H

2

S) must be completed at the well site. For accuracy, the sample must be drawn with the pump RUNNING, and the test be completed within ONE (1) minute after the sample is drawn.

Water softeners are designed to reduce hardness but can handle reasonable amounts of soluble iron if consideration is given to iron content when selecting model and regeneration settings. To treat sulfur (hydrogen sulfi de), bacterial iron, precipitated iron or very high levels of soluble iron special equipment in addition to a water softener is required. For best results, the Aqua-Pure ® APPM or APIF Series Systems are recommended for use on waters containing more than 2 ppm of iron.

1-1

Check Your Pumping Rate and Water Pressure:

Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage:

1) MINIMUM water pressure required at the water softener inlet is 20 psi (138 kPa).

CAUTION


• Do not install if water pressure exceeds 125 psi. If your water pressure exceeds 80 psi (552 kPa), you must install a pressure limiting valve. Contact a plumbing professional if you are uncertain how to check your water pressure.

NOTE: Call your local water department or plant operator to obtain pressure readings. If you have a private well, the gauge on the pressure tank will indicate the high and low system pressure. Record your water pressure data below:

Low psi

Water Pressure:

High psi

CAUTION


• Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum prevention.

The installer is required to take appropriate measures if there is the possibility a vacuum condition may occur. This would include the installation of an appropriate device in the supply line to the system, i.e., a vacuum breaker or backfl ow prevention device. Vacuum damage voids the factory warranty.

2) The pumping rate of your well must be suffi cient for satisfactory operation and BACKWASHING of the water softener. (See Specifi cations And

Operating Data, Section 7).

IMPORTANT NOTE

If sediment is present, the installation of a sediment pre-fi lter is recommended. Even if sediment is not currently present or at a level high enough to be objectionable, a pre-fi lter can help increase the effi ciency of the softener and help reduce the amount of maintenance required.

Installation Site Selection:

Select the location of your water softener with care. Various conditions which contribute to proper location are as follows:

1) Locate as close as possible to water supply source.

2) Locate as close as possible to a drain.

3) Locate in correct relationship to other water conditioning equipment (Figure 1, page 2-1).

4) Locate the water softener in the supply line BEFORE the water heater. Temperatures above 110°F (43°C) will damage the water softener and void the factory warranty.

5) DO NOT install the water softener in a location where freezing temperatures occur. Freezing may cause permanent damage and will also void the factory warranty.

6) Allow suffi cient space around the installation for easy servicing.

7) Provide a non-switched 110V, 60Hz (220V, 50Hz for specifi ed systems) power source for the control valve.

WARNING

To reduce the risk associated with ingestion of contaminants:

• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

CAUTION


• Protect from freezing, relieve pressure and drain system when temperatures are expected to drop below 40°F (4°C).

• Do not install on hot water supply lines. The maximum operating water temperature of this water softener is 110°F (43°C).

• Do not install in direct sunlight or outdoors.

1-2

Facts to Remember While Planning The Installation:

1) All installation procedures MUST conform to local and state plumbing codes.

2) If lawn sprinklers, a swimming pool, or geothermal heating/cooling or water for other devices/activities are to be treated by the water softener, a larger model MUST be selected to accommodate the higher fl ow rate plus the backwashing requirements of the water softener. Consult your Dealer/Installer or our Customer Service Department at 1-800-222-7880 for alternative instructions if the pumping rate is insuffi cient.

3) Remember that the water softener INLET is attached to the pipe that supplies water (i.e. delivers water from the well pump or after the water meter) and the OUTLET is the line that runs toward the water heater.

CAUTION



4) Before beginning the installation review the existing piping system and to determine the size, number and type of fi ttings required.

WARNING



5) Sweep the fl oor to eliminate objects that could pierce the brine tank.

IMPORTANT NOTE

SODIUM INFORMATION: Water softeners using sodium chloride for regeneration add sodium to the water. People who are on sodium restricted diets should consider the added sodium as part of their overall sodium intake.

Step 1) Remove unit from shipping box, inspect for damage and ensure all parts needed for installation are present. If parts are missing please contact our customer service department for help @ 1-800-222-7880. Remove the packing from unit and discard according to local, state and federal regulations. Locate the parts package and install the bypass and adapter fi ttings on the control valve to facilitate the connection to the customer’s water supply.

CAUTION


• On plastic fi ttings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic;


Step 2)

NOTE: Extension legs should be installed only whenever a salt dosage on any model water softener is more than 15 lbs. Models utilizing 15” x 15” x 34” brine tanks require salt grid extension legs when salting the water softener above 15 lbs. of salt or more. Grid legs extension kits are provided for CWS200 units. All other models requiring extension leg kits can be ordered through your Dealer/Installer or our Customer

Service Department at 1-800-222-7880.

Verify all packaging materials have been removed from the brine tank. On all units, legs rest on bottom of the brine tank.

Step 3) Shut off all water at main supply valve. On a private well system, turn off power to the pump and drain the pressure tank. Make certain pressure is relieved from the complete system by opening the faucet closest to the system.

CAUTION


• SHUT OFF FUEL OR ELECTRIC POWER SUPPLY TO WATER HEATER after water is shut off.

Step 4) Cut main supply line as required to fi t plumbing to inlet and outlet of unit.

Step 5) Attach plumbing. DO NOT apply heat to any fi tting connected to bypass or control valve as damage may result to internal parts or connecting adapters. Make certain water fl ow enters through inlet and discharges through outlet.

WARNING



CAUTION


• Do not apply heat to any fi tting connected to bypass or control valve as damage may result to internal parts or connecting adapters.



Step 6) The control valve allows for either a 3/4” NPT connection or 5/8” poly tubing for use as a drain line connection.

CAUTION


• On plastic fi ttings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic;

Step 7) Attach drain line to drain line fi tting. To prevent back pressure from reducing fl ow rate below minimum required for backwash, the drain line MUST BE sized according to run length and relative height. Be careful not to bend fl exible drain tubing sharply enough to cause “kinking” (if kinking occurs drain line MUST BE replaced). Typical examples of proper drain line diameters are:

1) 1/2” ID up to 15 ft. when discharge is lower than inlet.

2) 5/8” ID up to 15 ft. when discharge is slightly higher than the inlet.

3) 3/4” ID when drain is 25 ft. away and/or drain is installed overhead.

Some areas prohibit the use of fl exible drain lines. Check your local pluming code prior to installation.

Step 8) Position the drain line over the drain and secure fi rmly. To prevent back-siphoning of sewer water, provide an air-gap of at least 2” or 2 pipe diameters between end of drain hose and drain (Figure 3). DO NOT raise drain line more than 10 ft. above fl oor.

Step 9) Connect one end of the included 3/8” black polyethylene tubing to the brine fi tting located on the left side of the control valve.

Connect the other end to the safety brine valve elbow inside of the brine well in the brine tank. To do so, remove the retaining clip from the brine line fi tting on the control valve. The retaining clip is holding a plastic insert sleeve and needs to be inserted into the polyethylene tubing before installing the tubing into the fi tting elbow and hand tighten only. CAUTION: DO NOT use pli-

ers or wrenches to tighten as damage may occur and will void the manufacturer’s warranty.

Step 10) Install the overfl ow line to the brine tank overfl ow fi tting (Figure

2). The overfl ow discharge must be lower than the overfl ow fi tting. DO NOT interconnect overfl ow line with valve drain line.

Step 11) Make certain the bypass valve inlet and outlet knobs are in

“bypass” position. After all plumbing connections have been completed, open main water shut-off valve and restore power to well pump. Check for leaks and correct as necessary.

Step 12) Plug the control valve power cord into 110v/60Hz, non-switched power source. Program the control valve (refer to page 3-1).

NOTE: Regeneration settings for the control valve are factory preset. The control valve design permits adjustment of the salt setting. This adjustment may be necessary when unusual operating conditions exist, such as high concentrations of iron, manganese or hardness and/or high fl ow rates or daily water consumption.

Step 13) Manually set the control to backwash position. Press and hold the

REGEN button for 3 seconds. The valve will advance to the backwash position. Unplug power cord to prevent the unit from advancing automatically.

Step 14) Partially open the inlet knob on bypass valve (Figure 4). This will allow the unit to fi ll slowly from the bottom up, reducing air entrapment. Allow the unit to fi ll slowly, failure to do so could result in loss of resin to the drain. Once a steady stream of water, with no air sputtering, is fl owing to the drain, the inlet and outlet bypass knobs can be fully opened (refer to Figure 4).

Step 15) Plug the power cord back into the power source. Press the REGEN button and wait for the valve to advance to the next regeneration position.

Repeat the process until the valve is in the Service Position (Time of Day will be on the display).

Step 16) Refer to Section 3: Control Valve Programming and Regeneration Instructions, on how to set control valve for proper set up and regeneration settings.

SPECIAL SERVICE INSTRUCTIONS:

Under normal circumstances removal of the valve should not be required. However, if it must be removed, disconnect the plumbing attached to the bypass valve fi rst. Then, rotate the valve head assembly to the left or counter-clockwise. Before attempting any disassembly, pressure should be relieved by shutting off water to the system and opening a faucet. Upon reassembly, all o-rings should be lubricated with silicone grease. Reattach valve head assembly by rotating to the right or clockwise until valve head assembly is seated to the tank hand tight. Reconnect the plumbing to the bypass valve.

User Display Settings

General Operation

When the system is operating, one of two displays will be shown. Pressing NEXT will alternate between the displays.

One of the displays is always the current time of day. The second display is one of the following: days remaining or capacity remaining. Days remaining is the number of days left before the system goes through a regeneration cycle. Capacity remaining is the number of gallons that will be treated before the system goes through a regeneration cycle. The user can scroll between the displays as desired.

REGEN TODAY will be displayed if a regeneration is expected “Tonight.”

OR

If the system has called for a regeneration that will occur at the preset time of regeneration, the words “REGEN TODAY” will appear on the display.

When water is being treated (i.e. water is fl owing through the system) the word “SOFTENING” fl ashes on the display if a water meter is installed.

Regeneration Mode

Typically a system is set to regenerate at a time of low water usage. An example of a time with low water usage is when members of a household are asleep. If there is a demand for water when the system is regenerating, untreated water will be used.

When the system begins to regenerate, the display will change to include information about the step of the regeneration process and the time remaining for that step to be completed. The system runs through the steps automatically and will reset itself to help provide treated water when the regeneration has been completed.

Manual Regeneration

Sometimes there is a need to regenerate the system sooner than when the system calls for it, usually referred to as manual regeneration. There may be a period of heavy water usage because of guests or a heavy laundry day.

REGEN TODAY will

Flash if a regeneration is expected “Tonight.”

To initiate a manual regeneration at the present delayed regeneration time, press and release “REGEN”. The words “REGEN TODAY” will fl ash on the display to indicate that the system will regenerate at the preset delayed regeneration time.

NOTE: If you pressed the “REGEN” button in error, pressing the button again will cancel the request.

To initiate a manual regeneration immediately, press and hold the “REGEN” button for 3 seconds. The system will begin to regenerate immediately. The request cannot be cancelled.

NOTE: For water softeners, if brine tank does not contain salt, fi ll with salt and wait at least two hours before regenerating.

SECTION 4: MAINTENANCE

Replenishment of Salt Supply:

The salt storage capacity of the brine tank is approximately 180 lbs. (82 kg). During each regeneration a specifi c amount of salt is consumed, thus requiring its periodic replenishment for a continuous supply of softened water. The frequency and salt dosage level is dependent on the regeneration schedule. Always replenish salt before the supply is exhausted.

Type of Salt to Use:

Most types of water softener salt may be used. There are advantages and disadvantages to every type of salt. Please ask your local dealer for advice. 3M

Purifi cation does not allow the use of block type salt.

Brine Tank Clean-Out:

To help prevent service problems the brine tank should be emptied and fl ushed out with a garden hose annually or when dirt and other insolubles accumulate.

The clean-out should be done when the salt level is low. Do not perform this clean-out procedure during regeneration cycle.

Steps to follow:

(1) Disconnect brine line at either end.

(2) Turn brine tank upside down and discard old salt.

(3) Remove the salt shelf and rinse both the tank and salt shelf with a garden hose.

(4) Reinstall salt shelf and reconnect brine line.

(5) Before loading salt, using a pail or garden hose, add enough water to the brine tank to cover the lower portion of the salt shelf. Then add salt to brine tank.

Add one (1) cup of unscented laundry bleach to the brine well to sanitize the system.

Iron-Fouling of Media Bed:

If iron is present in the water supply, the water softener media bed will eventually become iron-fouled, resulting in reduced softening capacity and rust-stained fi xtures. Mixing one to two ounces of Iron Reduction Media with every 80 lbs. of salt added to brine tank will help minimize these problems from occurring.

Please contact your Dealer/Installer or our Customer Service Department at 1-800-222-7880 for additional information.

Periodically Check Time of Day Setting:

Power outages of eight hours or more will cause “TIME OF DAY” setting to become incorrect. To correct, refer to Section 3.

Malfunction of Unit:

Your water softener, under normal conditions, should provide years of virtually trouble-free service; however, since it is a mechanical device, it can malfunction.

(Please refer to our Troubleshooting Guide under Section 6, page 6-1 for additional information).

Change of Operating Conditions:

Should your family size, your water usage habits, or your water quality change, the regeneration program settings may have to be adjusted. Please contact your Dealer/Installer or our Customer Service Department at 1-800-222-7880 for additional information.

Special Service Instructions:

Under normal circumstances removal of the valve should not be required. However, if it must be removed, disconnect the plumbing attached to the bypass valve fi rst. Then, rotate the valve head assembly to the left or counter-clockwise. Before attempting any disassembly, pressure should be relieved by shutting off water to the system and opening a faucet. Upon reassembly, all o-rings should be lubricated with silicone grease. Reattach valve head assembly by rotating to the right or clockwise until valve head assembly is seated to the tank hand tight. Reconnect the plumbing to the bypass valve.

SECTION 5: CONTROL VALVE SERVICE INSTRUCTIONS

Drive Assembly:

Remove the valve cover to access the drive assembly.

IMPORTANT NOTE: Disconnect the power source plug (black wire) from the PC board prior to disconnecting the motor or water meter plugs from the

PC board. The power source plug connects to the four-pin jack. The motor plug connects to the two-pin jack on the left-hand side of the PC board.

The water meter plug (grey wire) connects to the three-pin jack on the far right-hand side of the PC board.

The PC board can be removed separately from the drive bracket but it is not recommended. Do not attempt to remove the display panel from the

PC board. Handle the board by the edges. To remove the PC board from the drive bracket, unplug the power, water meter and motor plugs from the PC board. Lift the middle latch along the top of the drive bracket while pulling outward on the top of the PC board. The drive bracket has two plastic pins that fi t into the holes on the lower edges of the PC board. Once the PC board is tilted about 45° from the drive bracket it can be lifted off of these pins. To reinstall the PC board, position the lower edge of the PC board so that the holes in the PC board line up with the plastic pins.

Push the top of the PC board towards the valve until it snaps under the middle latch, weave the power and water meter wires into the holders and reconnect the motor, water meter and power plugs.

The drive bracket must be removed to access the drive cap assembly and pistons or the drive cap gear cover. It is not necessary to remove the PC board from the drive bracket to remove the drive bracket. To remove the drive bracket, start by removing the plugs for the power source and the water meter. Unweave the wires from the side holders. Two tabs on the top of the drive back plate hold the drive bracket in place. Simultaneously lift the two tabs and gently ease the top of the drive bracket forward. The lower edge of the drive bracket has two notches that rest on the back plate. Lift up and outward on the drive bracket to disengage the notches.

To reassemble, seat the bottom of the drive bracket so the notches are engaged at the bottom of the drive back plate. Push the top of the drive bracket toward the two latches. The drive bracket may have to be lifted slightly to let the threaded piston rod pass through the hole in the drive bracket. Maintain a slight engaging force on top of the drive bracket while defl ecting the bracket slightly to the left by pressing on the side of the upper right corner. This helps the drive gears mesh with the drive cap assembly. The drive bracket is properly seated when it snaps under the latches on the drive back plate. If resistance is felt before latching, then notches are not fully engaged, the piston rod is not in the hole, the wires are jammed between the drive bracket and drive back plate, or the gear is not engaging the drive cap assembly. To inspect the drive gears, the drive gear cover needs to be removed. Before trying to remove the gear cover, the drive bracket must be removed from the drive back plate. (Refer to the proceeding instructions regarding removing the drive bracket from the drive back plate. The drive gear cover can be removed from the drive bracket without removing the motor or the PC board.) The drive gear cover is held in place on the drive bracket by three clips. The largest of the three clips is always orientated to the bottom of the drive bracket. With the PC board facing up, push in and down on the large clip on the drive gear cover. Handle the cover and the gears carefully so that the gears do not fall off of the pegs in the cover.

Replace broken or damaged drive gears. Do not lubricate any of the gears. Avoid getting any foreign matter on the refl ective coating because dirt or oils may interfere with pulse counting.

The drive gear cover only fi ts on one way, with the large clip orientated towards the bottom. If all three clips are outside of the gear shroud on the drive bracket and the drive gear cover slips easily into place.

The drive bracket does not need to be removed from the drive plate if the motor needs to be removed. To remove the motor, disconnect the power and motor plugs from the jacks on the PC board. Move the spring clip loop to the right and hold. Rotate the motor at least a 1/4 turn in either direction so the wires are vertical (up & down) before gently pulling on the wire connectors to remove the motor. Pulling directly on the wires without rotating the motor may break the wires off the motor.

Replace the motor if necessary. Do not lubricate the motor or the gears. To reinstall the motor, move the spring clip loop to the right and hold.

Gently turn the motor while inserting so that the gear on the motor meshes with the gears under the drive gear cover. Release the spring clip loop and continue to rotate the motor until the wires are horizontal and the motor housing engages the small plastic bulge inside the drive bracket motor retainer. Reconnect the motor plug to the two-pronged jack on the lower left hand side of the PC board. If the motor will not easily engage with the drive gears when reinstalling, lift and slightly rotate the motor before reinserting. Reconnect the power.

Replace the valve cover. After completing any valve maintenance, press and hold NEXT and REGEN buttons for 3 seconds or unplug power source jack (black wire) and plug back in. This resets the electronics and establishes the service piston position. The display should fl ash all wording, then

5-2

fl ash the software version (e.g. 181) and then reset the valve to the service position.

Drive Cap Assembly, Main Piston and Regenerant Piston:

The drive assembly must be removed to access the drive cap assembly. The drive cap assembly must be removed access the piston(s). The drive cap assembly is threaded into the control valve body and seals with an o-ring. To remove the drive cap assembly use the special plastic wrench or insert a ¼” to ½” fl at blade screwdriver into one of the slots around the top 2” of the drive cap assembly so it engages the notches molded into the drive back plate around 2” or the piston cavity. See Figure 5 on page 5-3. The notches are visible through the holes. Lever the screwdriver so the drive cap assembly turns to the left. Once loosened, unscrew the drive cap assembly by hand and pull straight out. The drive cap assembly contains the drive cap, the main drive gear, drive cap spline, piston rod and various other parts that should not be dissembled in the fi eld.

The only replaceable part on the drive cap assembly is the o-ring. Attached to the drive cap assembly is the main piston and a regenerant piston.

Figure 5

The regenerant piston (the small diameter one behind the main piston) is removed form the main piston by pressing sideways and unsnapping if from its latch. Chemically clean in dilute sodium bisulfi te or vinegar, or replace the regenerant piston if needed. After cleaning, rinse the component with clean water before wiping with a clean cloth. To remove the main piston fully extend the piston rod and then unsnap the main piston from its latch by pressing on the side with the number. Chemically clean in dilute sodium bisulfi te or vinegar, or replace the main piston. After cleaning, rinse the component with clean water before wiping with a clean cloth.

Reattach the main piston to the drive cap assembly. Reattach the regenerant piston (if needed) to the main piston. Do not lubricate the piston rod, main piston or regenerant piston. Lubricant will adversely affect the clear lip seals. Reinsert the drive cap assembly and piston into the spacer stack assembly and hand tighten the drive cap assembly. Continue to tighten the drive cap assembly using a screwdriver as a ratchet until the black o-ring on the spacer stack assembly is no longer visible through the drain port. Excessive force can break the notches molded into the drive back plate.

Make certain that the main drive gear still turns freely.

The exact position is not important as long as the main drive gear turns freely. Reattach the drive assembly to the control valve and connect all plugs.

After completing any valve maintenance, press and hold NEXT and REGEN buttons for 3 seconds or unplug power source jack (black wire) and plug back in. This resets the electronics and establishes the service piston position. The display should fl ash all wording, then fl ash the software version

(e.g. 181) and then reset the valve to the service position.

Spacer Stack Assembly:

To access the spacer stack assembly remove the drive assembly, drive cap assembly and piston. The spacer stack assembly can be removed easily without tools by using thumb and forefi nger. Inspect the black o-rings and clear lip seals for wear or damage. Replace the entire stack if necessary.

Do not disassemble.

The spacer stack assembly may be chemically cleaned (dilute sodium bisulfi te or vinegar) or wiped with a soft cloth. After chemically cleaning, rinse the component with clean water before wiping with a clean cloth.

The spacer stack assembly can be pushed into the control valve body bore by hand. Since the spacer stack assembly can be compressed it is easier to use a blunt object (5/8” to 1-1/8” in diameter) to push the center of the assembly into the control valve body. The assembly is properly seated with at least four threads exposed (approximately 5/8’). Do not force the spacer stack assembly in. The control valve body bore interior can be lubricated with silicone to allow for easy insertion of the entire stack. Do not use silicone or any other type of lubricant on the clear lip seals of the piston.

Reattach the drive cap assembly and piston(s) and the drive assembly.

After completing any valve maintenance, press and hold NEXT and REGEN buttons for 3 seconds or unplug power source jack (black wire) and plug back in. This resets the electronics and establishes the service piston position. The display should fl ash all wording, then fl ash the software version

(e.g. 181) and then reset the valve to the service position.

Injector Cap, Screen, Injector Plug and Injector:

Unscrew the injector cap and lift off. Loosen cap with special plastic wrench or pliers if necessary. Attached to the injector cap is a screen. Remove the screen and clean if fouled. The plug and/or injector can be pried out with a small screwdriver. The plug can be wiped clean. If the plug leaks replace the entire plug. The injector consists of a throat and a nozzle. Chemically clean the injector with vinegar or sodium bisulfi te. After chemically cleaning, rinse the component with clean water before wiping with a clean cloth. The holes can be blown out with air. Both pieces have a small

5-3

diameter holes that control the fl ow rates of water so that the proper concentration of regenerant is used. Sharp objects, which can score the plastic, should not be used to clean the injector. Scoring the injector or increasing the diameter of the hole could change the operating parameters of the injector. Push the plug(s) and/or injectors fi rmly in place, replace the screen and hand tighten the injector cap.

Refi ll Flow Control Assembly or Refi ll Port Plug:

To clean or replace the refi ll fl ow control, pull out the elbow-locking clip and then pull straight up on the elbow. Replace the elbow locking clip in the slot so that it is not misplaced. Twist to remove the white fl ow control retainer. The fl ow control can be removed by prying upward through the side slots of the retainer with a small fl at blade screwdriver.

Chemically clean the fl ow control or the white fl ow control retainer using dilute sodium bisulfi te or vinegar. After chemically cleaning, rinse the component with clean water before wiping with a clean cloth. Do not use a wire brush. If necessary, replace the fl ow control, o-ring on the fl ow control retainer, or the o-ring on the elbow.

Reseat the fl ow control so the rounded end is visible in the fl ow control. Reseat the white fl ow control retainer by pushing the retainer into the elbow until the o-ring seats. Remove locking clip, push down on elbow to reseat and insert locking clip. Do not use petroleum jelly, oils, or other unacceptable lubricants on o-rings. A silicone lubricant may be used on the o-ring on the elbow or the white retainer.

Water Meter or Meter Plug:

The water meter assembly is connected to the PC board by a wire. If the entire water meter assembly is to be replaced, remove the control valve cover and disconnect the power source and water meter plugs from the PC board. Unlatch the drive assembly and lean if forward. Unthread the water meter wire from the side of the drive assembly and through the drive back plate. To reinstall, rethread the water meter wire through the drive back plate and the side of the drive assembly. Reattach the drive assembly and the water meter and power plugs. If no water meter wire is visible, then a plug is installed, not a water meter. The water meter wire does not need to be removed from the PC board if the water meter is only being inspected and cleaned. To remove the water meter assembly, unscrew the meter cap on the left side of the control valve. Pliers may be used to unscrew the nut if necessary. With the nut removed, a slot at the top of the water meter is visible. Twist a fl at blade screwdriver in the slot between the control valve body and the meter. When the meter is part way out it is easy to remove the water meter from the housing. Once the water meter is removed from the control valve body, gently pull forward on the turbine to remove it from the shaft.

Do not use a wire brush to clean the turbine. Wipe with a clean cloth or chemically clean in dilute sodium bisulfi te or vinegar. After chemically cleaning, rinse the component with clean water before wiping with a clean cloth. The turbine can be immersed in the chemical. Do not immerse electronics. If the turbine is scored or damaged or the bearing on the turbine are worn, replace the turbine.

Do not lubricate the turbine shaft. The turbine shaft bearings are prelubricated. Do not use petroleum jelly, oils, or other unacceptable lubricants on the o-ring. A silicone lubricant may be used on the black o-ring.

Snap the turbine on the shaft and reinsert the water meter into the side slot. Hand tighten the nut. Do not use a pipe wrench to tighten nut.

Bypass Valve:

The working parts of the bypass valve are the rotor assemblies that are contained under the bypass valve caps. Before working on the rotors, make sure the system is depressurized. Turn the red arrow shaped handles towards the center of the bypass valve and back several times to ensure rotor is turning freely.

The nuts and caps are designed to be unscrewed or tightened by hand. If necessary a pliers can be used to unscrew the nut or cap. Do not use a pipe wrench to tighten or loosen nuts or caps. Do not place screwdriver in slots on caps and/or tap with a hammer. To access the rotor, unscrew the cap and lift the cap, rotor and handle out as one unit. Twisting the unit as you pull it out will help to remove it more easily. There are three o-rings: one under the rotor cap, one on the rotor stem and the rotor seal. Replace worn o-rings. Clean rotor. Reinstall rotor.

When reinstalling the red arrow handles be sure that:

1. The handle pointers are lined up with the control valve body arrows, and the rotor seal o-ring and the retainer on both rotors face to the right when being viewed from the front of the control valve; or

2. Arrows point toward each other in the bypass position.

Since the handles can be pulled off, they could be accidentally reinstalled 180° from their correct orientation. To install the red arrow handles correctly, keep the handles pointed in the same direction as the arrows engraved on the control valve body while tightening the bypass valve caps. After completing and valve maintenance, press and hold NEXT and REGEN buttons for 3 seconds or unplug power source jack (black wire) and plug back in. The resets the electronics and establishes the service piston position. The display should fl ash all wording, then fl ash the software version (e.g.

181) and then reset the valve to the service position.

These softeners conform to NSF/ANSI 44 for the specifi c performance claims as verifi ed and substantiated by test data. These models are effi ciency rated. The effi ciency rating is valid only at the stated salt dose and maximum service fl ow rate. They have a demand initiated regeneration (D.I.R.) feature that complies with specifi c performance specifi cations intended to minimize the amount of regenerant brine and water used in their operation. These softeners have a rated softener effi ciency of not less than 3350 grains of total hardness exchange per pound of salt (based on sodium chloride) and shall not deliver more salt than their listed ratings. The rated salt effi ciency is measured by laboratory tests described in NSF/ANSI Standard 44. These tests represent the maximum possible effi ciency that the systems can achieve. Operational effi ciency is the actual effi ciency after the system has been installed. It is typically less than the effi ciency due to individual application factors including water hardness, water usage, and other contaminants that reduce the softener’s capacity. These systems are not intended for use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. For best results, use coarse solar salt. Refer to this Installation/operation manual and the limited warranty for further details on installation, parts and service, maintenance and further restrictions or limitations to the use of the product.
