General Warnings

• The control valve, ﬁttings and/or bypass are designed to accommodate minor plumbing misalignments but are not designed to support the weight of a system or the plumbing.

• HYDROCARBONS SUCH AS KEROSENE, BENZENE, GASOLINE, ETC., MAY DAMAGE PRODUCTS THAT CONTAIN O-RINGS OR PLASTIC COMPONENTS. EXPOSURE TO SUCH HYDROCARBONS MAY CAUSE THE PRODUCTS TO LEAK. DO NOT USE THE PRODUCT(S) CONTAINED IN THIS DOCUMENT ON WATER SUPPLIES THAT CONTAIN HYDROCARBONS SUCH AS KEROSENE, BENZENE, GASOLINE, ETC.

• THIS WATER METER SHOULD NOT BE USED AS THE PRIMARY MONITORING DEVICE FOR CRITICAL OR HEALTH EFFECT APPLICATIONS.

• Do not use Vaseline, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may be used on black o-rings but is not necessary.

• The nuts and caps are designed to be unscrewed or tightened by hand or with the special plastic wrench. 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 a screwdriver in the slots on caps and/or tap with a hammer.

• Do not use pipe dope or other sealants on threads. Use Teﬂon tape on the threaded inlet, outlet and drain ﬁttings. Teﬂon tape is not necessary on the nut connection or caps because of o-ring seals.

• After completing any valve maintenance involving the drive assembly or the drive cap assembly and pistons unplug power source jack from the printed circuit board (black wire) and plug back in or press and hold NEXT and REGEN buttons for 3 seconds. This resets the electronics and establishes the service piston position. The display should ﬂash all wording, then ﬂash the software version and then reset the valve to the service position.

• All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain line should be a minimum of ½”. Backwash ﬂow rates in excess of 7 gpm (26.5 lpm) or length in excess of 20’ (6.1m) require ¾” drain line.

• Solder joints near the drain must be done prior to connecting the drain line ﬂow control ﬁtting. Leave at least 6” between the drain line control ﬁtting and solder joints when soldering pipes that are connected on the drain line control ﬁtting. Failure to do this could cause interior damage to the drain line ﬂow control ﬁtting.

• When assembling the installation ﬁtting package (inlet and outlet), connect the ﬁtting to the plumbing system ﬁrst and then attach the nut, split ring and o-ring. Heat from soldering or solvent cements may damage the nut, split ring or o-ring. Solder joints should be cool and solvent cements should be set before installing the nut, split ring and o-ring. Avoid getting primer and solvent cement on any part of the o-rings, split rings, bypass valve or control valve.

• Plug into an electrical outlet.

NOTICE

All electrical connections must be connected according to local codes. (Be certain the outlet is uninterrupted.)

W100T Twin Alternating Series Softeners 3

• Install grounding strap on metal pipes.

General Warnings (continued)

• This glass ﬁlled Noryl1 (or equivalent) fully automatic control valve is designed as the primary control center to direct and regulate all cycles of a water softener or ﬁlter.

• The control valve is compatible with a variety of regenerants and resin cleaners. The control valve is capable of routing the ﬂow of water in the necessary paths to regenerate or backwash water treatment systems. The injector regulates the ﬂow of brine or other regenerants. The control valve regulates the ﬂow rates for backwashing, rinsing, and the replenishing of treated water into a regenerant tank, when applicable.

• Control valve installation is made easy because the distributor tube can be cut ½” above to ½” below the top of tank thread. The distributor tube is held in place by an o-ring seal and the control valve also has a bayonet lock feature for upper distributor baskets.

• The power adapter comes with a 15 foot power cord and is designed for use with the control valve. The power adapter is for dry location use only. The control valve remembers all settings until the battery power is depleted if the power goes out.

• After the battery power is depleted, the only item that needs to be reset is the time of day; other values are permanently stored in the nonvolatile memory. The control valve battery is not rechargeable but is replaceable.

• No user serviceable parts are on the PC board, the motor or the power adapter. The means of disconnection from the main power supply is by unplugging the power adapter from the wall.

How To Use This Manual

This installation manual is designed to guide the installer through the process of installing and starting up water conditioning systems featuring the ProSense controller. This manual is a reference and will not include every system installation situation. The person installing this equipment should have:

• Training on the control valve.

• Knowledge of water conditioning and how to determine proper

control settings.

• Adequate plumbing skills.

Pre-Installation Considerations

A. Water Pressure

A minimum of 25 pounds of water pressure is required for regeneration valve to operate effectively.

B. Electrical Facilities

A continuous 115 volt, 60 Hertz current supply is required. Make certain the current supply is always hot and cannot be turned off with another switch.

C. Existing Plumbing

Condition of existing plumbing should be free from lime and iron buildup. Piping that is built up heavily with lime and/or iron should be replaced. If piping is clogged with iron, a separate iron ﬁlter unit should be installed ahead of the water softener.

D. Location Of Softener And Drain

The softener should be located close to a drain.

E. Bypass Valves

Always provide for the installation of a bypass valve.

F. Valve to Tank Installation Instructions

1. Spin the valve onto the tank, ensuring the threads are not crossthreaded.

NOTICE

The main control valve and tank adaptor have right-hand threads, or clockwise, to install

2. Rotate the valve freely without using force until it comes to a stop (this position is considered zero).

3. Rotate the valve clockwise from zero, between ¼ turn and ½ turn to fully tighten. No tools are needed. Hand tight is enough. Overtightening may cause valve or tank damage.

NOTICE

If lubricant is required, a silicone compound is strongly recommended. Dow Corning Watts), is recommended for best possible results. Dow Corning Release Compound is used in the manufacture of this control valve. The use of other types of lubricants may attack the control’s plastic or rubber components. Petroleum-based lubricants can cause swelling in rubber parts, including O-rings and seals.

Pre-Installation Considerations (continued)

G. Pre Installation and Loading of Media

Systems that are 13” in diameter and larger are not loaded with media. These systems must be loaded with media before placing into service. To load a system follow the below steps.

1. Cap the top open end of the distributor tube with tape and plastic sheeting to keep foreign debris from entering the distributor tube. This cap must be secure and not come off during media loading.

2. Place the distributor tube, screen end down, into the mineral tank and center it in the bottom. The top of the distributor tube should be ﬂush with the top of the tank. If 4” x 2.5” tank bushings are used, the distributor tube should be ﬂush with the top of the tank bushing.

3. Make sure the plastic and tape cap is secure to the top of the distributor tube, place a funnel on the top of the tank and load ﬁrst the gravel (if different sizes of gravel are used load the largest gravel ﬁrst, then the smaller gravel) then the resin media into the tank. The cap must not come off of the distributor tube during the loading of the media.

4. Remove the plastic cap from the distributor tube. DO NOT PULL UP ON THE DISTRIBUTOR TUBE when removing the cap. The distributor tube top must remain ﬂush with the top of the tank.

5. Clean any media from the threads and top of the mineral tank.

6. Lubricate the O-rings on the bottom of the control valve (distributor pilot O-ring and top of tank O-ring). Use nonpetroleum based silicone lubricant only.

7. Place the control valve on top of the tank. When doing this step, seat the top of the distributor tube inside the centered O-ring sealed port on the bottom of the valve ﬁrst then press the valve down until the tank threads come in contact with the valve threads. This ensures that the distributor tube is properly seated into the bottom of the control valve. Thread the valve on to the tank clockwise. Be careful not to cross thread the valve or over tighten it. A hand tight snug ﬁt is appropriate for the control valve torque. A wrench is not necessary. Do not use thread sealant or PTFE tape on the valve base threads.

8. The system is now ready for installation. Follow the Installation Section in the Installation, Operation and Maintenance Manual.

WARNING

Do not exceed water pressure of 120 psi (8.2 bar). Do not exceed 110°F (43.3°C). Do not subject unit to freezing conditions.

General Installation Instructions

1. Turn off water heater(s).

2. Turn off the main water supply to the home and open an inside faucet (cold and hot) to relieve any pressure within the plumbing system.

3. Place the system in the desired installation location. Make sure that the location is level and sturdy enough to support the weight of the system once it is in operation.

4. Place the bypass valve in the bypass position.

5. Connect the cold water supply to the inlet of the water conditioning system. While constructing the supply line, install a master supply valve (user supplied) in the supply line and close it.

6. Connect the feed water line to the home to the outlet of the system.

7. Plumb the drain line to an appropriate drain abiding by all local, city, and state codes. Use a 3/4” drain line for backwash ﬂow rates of 7 gpm or for drain lines of 7 gpm and less that exceed 20’ in length. Use a 1” drain line for backwash ﬂow rates of 10 gpm and 12 gpm.

8. Connect the brine tank to the water softener control valve brine inlet port using the factory supplied ﬁttings and tubing. Add enough water to the brine tank so that water covers the top of the air check. DO NOT ADD SALT AT THIS TIME.

9. Open the user supplied feed water valve. Check for leaks and repair as needed.

10. Allow the inside hot and cold faucet to remain open until all air has been purged from the plumbing system. Then close the faucet.

11. Locate Manual Regeneration Options in this manual to see the steps to initiate an Immediate Manual Regeneration. Once you have read that section place the system in backwash and unplug the system from its electrical outlet once it has cycled into the backwash position. This will stall the unit in backwash so all air can be purged from one of the tanks.

12. Adjust the user supplied feed water valve to 1/4 open and place the bypass valve into the service position.

13. Air will come out of the drain line until the backwashing tank is completely purged of air. Then water will ﬂow to drain. Allow water to ﬂow to drain for 15 minutes or until the water to drain is clear of resin color throw.

14. Plug the system back into the electrical outlet and manually cycle it through the remaining regeneration steps until it arrives in the service position.

15. Repeat installation steps 11, 12, 13, and 14 of the General Installation Instructions to purge the air from the second tank.

16. Check for leaks and repair as needed.

17. Installation is now complete and the system is ready for programming and one cycle of brine tank reﬁll so that the correct amount of water is in the brine tank for the ﬁrst regeneration cycle. The brine tank reﬁll must be done after programming the system.

Select OFF when none of these features are used.

B. Conﬁguring the Control Valve for Separate Source Operation:

Select SEPS for control operation. For separate source operation the three wire connector is not used. Selection requires that a connection to a Motorized Alternator Valve (MAV) is made to the two pin

connector labeled ALTERNATOR DRIVE located on the printed circuit board. The C port of the MAV must be connected to the valve inlet and the A port connected to the separate source used during regeneration. The B port must be connected to the feed water supply.

When set to SEPS the MAV will be driven closed before the ﬁrst regeneration cycle, and be driven open after the last regeneration cycle.

NOTE: If the control valve enters into an error state during regeneration mode, the MAV will

remain in its current state until the error is corrected and reset.

C. Selecting the Control Valve to act as an alternator:

519.0 and higher = Use 3-wire Interconnect Cables for all communication between units.

518.3 and lower = Use 2-wire Interconnect Cables for twin alternators with independent ﬂow meters.

Prior to starting the programming steps, connect the interconnect cable to each control valve board’s three pin connector labeled “INTERCONNECT”. Also connect the meter cord to either control valve to the three pin connector labeled “METER”.

NOTICE

Watts W100T Twin alternators can be set up to operate with a day over-ride setting in conjunction with the main volume based regeneration setting. If a system is programmed for twin alternating with a delayed regeneration, a W100T twin alternator can perform an immediate transfer of the MAV to place a fully regenerated tank on-line and have a delayed regeneration time for the exhausted unit. W100T Twin alternators will only count days on the unit that is on-line which will allow the twin alternating system to regenerate based on only a day over-ride setting when programmed to regenerate based on days.

For Watts Twin Alternating systems using W100T, CWS150, and CWS200 valves there will be an option to delay the last two cycles of regeneration (only “Rinse” and “Fill”). This feature splits the regeneration into two portions. The ﬁrst portion of the regeneration will start immediately and all programmed cycles before the “Rinse” and “Fill” cycles will be performed. After all programmed cycles before “Rinse” and “Fill” are completed the control valve will drive to the service position (displaying “Delayed Rinse + Fill Pending”). When the volume of the on-line unit is depleted to 10% of its programmed capacity, the control valve will be triggered to ﬁnish the second portion of the regeneration and complete the “Rinse” and “Fill” cycles and return to Service and be placed into Standby mode, and wait to come on-line for service.

Step 7CS

Selecting the use of an outside signal to initiate a regeneration: Selection only matters if a connection is made to the two pin connector labeled DP SWITCH located on the printed circuit board. Following is an explanation of the options:

oFF - Feature not used. NOTE: In a twin alternating system each control must

have a separate dP signal or dP switch. One dP signal or one dP switch cannot be used for both controls.

on0 – If the dP switch is closed for an accumulative time of

2 minutes a regeneration will be signaled to the unit. In a twin alternating system the MAV will transition ﬁrst to switch units so that the signaled unit can start regeneration. After the MAV has fully transitioned, the regeneration begins immediately.

NOTE: For W100T-CWS200 control valves

programmed for twin alternating: if the dP function “on0” is set, the Delayed Rinse and Fill feature is not available.

dELy – If the dP switch is closed for an accumulative time of

2 minutes a regeneration will occur at the scheduled delayed regeneration time. In a twin alternating system once the dP switch is triggered the PC Board will display “REGEN TODAY” and when the delayed regen time comes the control will switch tanks and the triggered unit will then go into regeneration.

NOTE: For W100T-CWS200 control valves

programmed for twin alternating: if the dP function “dEL” is set, the Delayed Rinse and Fill feature is not available.

HoLd – If the dP switch is closed a regeneration will be

prevented from occurring while there is switch closure. In a twin alternating system the regeneration of a unit can be prevented upon switch closure. If the unit depletes the capacity down to zero, it will not be allowed to switch tanks to regenerate until the switch is open.

NOTE: For W100T-CWS200 control valves

programmed for twin alternating the Delayed Rinse and Fill feature can be set in conjunction with the “HoLd” if desired.

W100T Control Valve System Description

The W100T control valves consist of the following components:

1. Drive Assembly

2. Drive Cap Assembly, Main Piston and Regenerant Piston

3. Spacer Stack Assembly

4. Injector Cap, Screen, Injector Plug and Injector

Drive Assembly

The drive assembly consists of the following parts:

• Drive Bracket

• Printed Circuit (PC) Board

• Motor

• Drive Gears

• Drive Gear Cover

The drive bracket holds the PC board, the motor, the drive gears and the drive gear cover in place.

The PC board receives and retains information, displays the information, determines when to regenerate and initiates regeneration. The display shows different types of information in the initial system set up (for softeners or ﬁlters), installer display settings, diagnostics, valve history or user display settings.

The PC board powers the motor. The PC board’s two-prong jack connects wires to the direct current (DC) motor. The motor is held in place on the drive bracket by a spring-loaded clip and a small bulge in the plastic, which ﬁts in one of the slots on the motor housing. The motor turns drive gears that drive the piston to cycle positions for backwashing, regeneration, rinsing, reﬁll or service. The motor is fully reversible (turns both ways) and changes direction of rotation to change the direction of piston motion. The motor is easily replaced if necessary.

5. Reﬁll Flow Control Assembly or Reﬁll Port Plug

6. Drain Line Flow Control and Fitting Assembly

7. Water Meter

8. Twin Transfer Valve

There are three drive gears held in place by the drive gear cover. All three drive gears are the same size. A reﬂective coating is applied to the gears. As the center drive gear turns a light shines on the coating and a light sensing diode determines if a light pulse was returned. The PC board counts the pulses and determines when to stop driving the motor.

Drive Cap Assembly, Main Piston and Regenerant Piston

The drive gears turn the main gear of the drive cap assembly, which moves the piston. The screw-driven, horizontally moving piston stops at speciﬁc positions to direct the ﬂow of water to backwash, regenerate, rinse or reﬁll. The PC board determines the position of the piston by counting pulses produced when the piston is moved. An optical sensor looking at one of the reduction drive gears generates these pulses. Each cycle position is deﬁned by a number of pulses. The counter is zeroed each time the valve goes to the service position. The PC board ﬁnds the service position by noting the increase in current delivered to the motor when the mechanical stop at the service position is reached. This method of controlling piston position allows for greater ﬂexibility and requires no switches or cams (U.S. Patent 6444127).

One of two main pistons is always used:

1. A 1.25" diameter downﬂow piston is used when the W100T control valve is used as a downﬂow softener, regenerating ﬁlter or nonregenerating ﬁlter.

2. A 1.25" diameter upﬂow piston is used when the W100T control valve is used as an upﬂow softener. Upﬂow option not applicable for EA, EE or EI control valves.

If the control valve is used as a softener or a regenerating ﬁlter, a regenerant piston must be attached to the main piston. If the control valve is to be used on a system that does not require a regenerant to be added, the regenerant piston must be removed.

Spacer Stack Assembly

The spacer stack assembly provides the necessary ﬂow passage for water during the different cycles. The all-plastic spacer stack assembly (U.S. Patent 6402944) is a one-piece design which allows the stack to be removed using your ﬁngers.

The exterior of the stack is sealed against the body bore with self lubricating EPDM o-rings, while the interior surface is sealed against the piston using slippery self cleaning directional (one-way) silicone lip seals. The lip seals are clear in color and have a special slippery coating so

that the piston does not need to be lubricated.

Injector Cap, Screen, Injector Plug and Injector

The screen, injector and/or injector plug(s) are installed under the injector cap in an easy to access location on top of the valve. The injector cap contains four slots so no water accumulates in the cap. The injector cap is designed to be hand tightened.

Under the injector cap there is an easy to clean removable screen to prevent fouling of the injector. There are two holes under the injector cap labeled “DN” and “UP”. The holes will be ﬁlled with a plug or an injector.

The plug (Order # V3010-1Z) prevents water from traveling a certain pathway. The injector lets water pass through the pathway. The selfpriming injector increases the velocity of the water, creating a zone of negative pressure that draws in the concentrated liquid regenerant, such as sodium chloride (brine), potassium permanganate, etc. The regenerant blends with the stream of water, which passes through the media to regenerate the bed.

The injector provides a consistent regenerant/water mixture ratio over the entire operating pressure range of the control valve. The injector provides good performance in a variety of applications, which may involve elevated drain lines and long regenerant draw lengths. Injectors are chosen by knowing the type, amount, and regenerant ﬂow rate for a particular type of media. Guidelines can be found in the media manufacturer’s literature. The color coded injectors give different regenerant draw, slow rinse and total ﬂow rates over the pressure range. See injector graphs (pages 25-28) for total, slow rinse and draw ﬂow rates.

The control valve has been manufactured to be one of the following:

• regeneration downﬂow W100T (for softeners or regenerating ﬁlters install injector in DN location, plug in UP location)

• regeneration upﬂow W100T (upﬂow option is for softeners only, which are not EA, EE or EI control valves. Install injector in UP location,

plug in other hole location)

• no regenerant W100T (both the DN and UP holes have injector plugs installed) and plug installed for the reﬁll elbow

NOTICE

It is okay to ﬁeld convert valves from upﬂow to downﬂow and vice versa with the W100T valve as long as software supports upﬂow brine.

Reﬁll Flow Control Assembly or Reﬁll Port Plug

The reﬁll ﬂow control assembly consists of a reﬁll ﬂow elbow, reﬁll ﬂow control retainer assembly, reﬁll ﬂow control, polytube insert and nut assembly. The reﬁll ﬂow control retainer ﬁts in the reﬁll elbow. The reﬁll ﬂow control retainer houses the reﬁll ﬂow control which controls the ﬂow rate when the regenerant tank is being reﬁlled. The reﬁll ﬂow control is a ﬂexible washer-like part with a small oriﬁce and a precision molded contour that delivers a steady 0.5 gpm regenerant tank reﬁll rate at varying inlet pressures. Reﬁll is accomplished with treated water.

The reﬁll ﬂow control assembly is installed in an easy to access reﬁll elbow located on top of the control valve. The reﬁll ﬂow control assembly is attached to the control valve with a locking clip. The locking clip allows the elbow to rotate 270 degrees so the outlet can be orientated towards the regenerant tank.

The control valve has a standard reﬁll elbow to which a 3/8” ﬂexible tube can be connected. An optional elbow can be ordered which accommodates a ½” ﬂexible tube for a high regenerant draw rate situation. Both elbows use the same reﬁll ﬂow control and retainer.

If the control valve is to be used as a non-regenerant ﬁlter control valve, the reﬁll elbow is removed and replaced with a reﬁll port plug P/N V3195-01.

Drain Line Flow Control and Fitting Assembly

The drain line ﬂow control assembly includes a drain line ﬂow control and a ﬁtting. The drain line ﬂow control allows proper media bed expansion by regulating the ﬂow rate to the drain. The drain line ﬂow control is a ﬂexible washer-like part with an oriﬁce and a precision molded contour. The ﬂow rates are within ± 10% over the pressure range of 20 psi to 125 psi (1.4 bar to 8.6 bar). See table for ﬂow rate information.

The drain line ﬂow control and ﬁtting are located on top of the control valve and replaceable without the use of special tools.

The drain line ﬂow control can be installed in the standard ¾” drain line elbow, which accommodates 5/8” polytube or ¾” NPT drain line connections. The optional nut and polytube insert for the ¾” drain line elbow is designed for use with ﬂexible polytube only. The ¾” drain line elbow can be rotated 180 degrees so the outlet can be orientated to the nearest drain. The same retainer is used for all drain line ﬂow controls for the ¾” ﬁtting. Drain line ﬂow controls designed for the 3/4” ﬁtting are available for ﬂow rates ranging from 0.7 to 10 gpm (2.6 to 37.9 lpm).

An optional 1” straight drain line ﬁtting is available to accommodate drain line ﬂow rates ranging from 9 to 25 gpm (34.1 to 94.6 lpm). This ﬁtting is straight but still connects to the control valve using the same locking clip. The drain line ﬂow control is located between two ﬁtted parts (i.e. the ﬁtting acts as the retainer). The nut is unscrewed to access the drain line ﬂow control.

Service Instructions

Drive Assembly

Remove the valve cover to access the drive assembly.

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 (gray 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 ﬁt into the holes on the lower edge 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 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 drive 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 deﬂecting 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 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 instructions above 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 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 reﬂective coating because dirt or oils may interfere with pulse counting.

The drive gear cover only ﬁts 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 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 ¼ 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 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 plug.

Replace the valve cover. After completing any valve maintenance involving the drive assembly or the drive cap assembly and pistons unplug power source jack from the printed circuit board (black wire) and plug back in or press and hold NEXT and REGEN buttons for 3 seconds.This resets the electronics and establishes the service piston position. The display should ﬂash all wording, then ﬂash the software version and then reset the valve to the service position.

W100T Twin Alternating Series Softeners 37

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 to 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” ﬂat 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 the top 2” of the piston cavity. The notches are visible through the holes. Lever the screwdriver so the drive cap assembly turns counter clockwise. 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 ﬁeld. The only replaceable part on the drive cap assembly is the o-ring. Attached to the drive cap assembly is the main piston (downﬂow or upﬂow) and if a regenerant is used, a regenerant piston. Upﬂow is not applicable to EA, EE or EI control valves.

The regenerant piston (the small diameter one behind the main piston) is removed from the main piston by pressing sideways and unsnapping it from its latch. Chemically clean in dilute sodium bisulﬁte or vinegar, or replace the regenerant piston if needed. 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 bisulﬁte or vinegar, or replace the main piston.

Reattach the main piston to the drive cap assembly. Reattach the regenerant piston (if needed) to the main piston. 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 of the piston 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 involving the drive assembly or the drive cap assembly and pistons unplug power source jack from the printed circuit board (black wire) and plug back in or press and hold NEXT and REGEN buttons for 3 seconds. This resets the electronics and establishes the service piston position. The display should ﬂash all wording, then ﬂash the software version 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 foreﬁnger. Inspect the black o-rings and clear lip seals for wear or damage. Replace the entire stack if necessary. Do not disassemble the stack.

The spacer stack assembly may be chemically cleaned (dilute sodium bisulﬁte or vinegar) or wiped with a soft cloth.

The spacer stack assembly can be pushed in to 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 when at least four threads are 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.

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

After completing any valve maintenance involving the drive assembly or the drive cap assembly and pistons unplug power source jack from the printed circuit board (black wire) and plug back in or press and hold NEXT and REGEN buttons for 3 seconds. This resets the electronics and establishes the service piston position. The display should ﬂash all wording, then ﬂash the software version 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 bisulﬁte. The holes can be blown out with air. Both pieces have small diameter holes that control the ﬂow rates of water to insure 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.

NOTICE

Two holes are labeled DN and UP. Check for compliance. Refer to Valve Body Compliance Table at the begining of this manual.

Push the plug(s) and/or injectors ﬁrmly in place, replace the screen and hand tighten the injector cap.

Reﬁll Flow Control Assembly or Reﬁll Port Plug

To clean or replace the reﬁll ﬂow 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 ﬂow control retainer. The ﬂow control can be removed by prying upward through the side slots of the retainer with a small ﬂat blade screwdriver.

Chemically clean the ﬂow control or the white ﬂow control retainer using dilute sodium bisulﬁte or vinegar. Do not use a wire brush. If necessary, replace the ﬂow control, o-ring on the ﬂow control retainer, or the o-ring on the elbow.

Reseat the ﬂow control so the rounded end is visible in the ﬂow control. Reseat the white ﬂow 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 Vaseline, 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

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 it 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 ﬂat 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 bisulﬁte or vinegar. The turbine can be immersed in the chemical. Do not immerse electronics. If the turbine is scored or damaged or the bearings on the turbine are worn, replace the turbine.

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

Reinsert the water meter into the side slot. Hand tighten the nut. Do not use a pipe wrench to tighten nut.

Servicing Transfer Cap Assemblies

Release locking tabs from each side to remove back plate.

The control valves backplate must be removed ﬁrst to allow access to removing the transfer cap assembly.

Hold slight downward pressure on the top left corner of the backplate while using a thin ﬂat screwdriver or knife blade to push in on the locking tabs, this will release the backplate and it will twist to the left off of the valve body. For removal of the drive motor side you will need to remove the drive cover assembly to access the motorized drive. The drive motor can be removed by pressing the spring clip loop to the right then rotate the motor a ¼ turn and pull outward to remove the motor from the reducing gear cover assembly. Remove the three Phillips head stainless steel screws that retain the reducing gear cover to the drive cap. Once the cover is removed you have access to the reducing drive gears simply slide them off of the gear axles with your ﬁngers to inspect / check them there are 3 small black gears with foil decals and 1 larger

black reducing gear. Remove the large white drive gear from the stainless steel drive shaft. To remove the large white transfer drive gear ﬁrmly grab the outside edge of the gear with your ﬁngers and pull it outward away from the control valve assembly. Now you can use a 5/32” or 4mm allen wrench to remove the ¼-20 screws that retain the transfer drive cap assemblies on both sides of the valve.

Once the screws are removed from retaining the inlet side transfer valve cap and the outlet drive motor transfer cap from the control valve the cap will spring out away from the valve body. At this point the transfer discs may be removed by pulling the discs outward off of the shaft away from the valve body with your hand. With the disc out you can inspect the ﬂat surface area to be sure it’s clean and smooth free of any debris or scratches. Note that the disc is keyed to the drive shaft so that it will only assemble in one orientation. The transfer discs may be chemically cleaned with a dilute sodium bisulfate solution, vinegar or just wiped with a soft clean cloth.

Seal "Lip" feature

To remove seals gently pull out on the outer lip of the seal to lift the seal out from its cavity being careful not to damage the face surface of the seal. To reassemble re-seat seals into the seal cavity of the control valve body being sure that the lip of the seal is facing outward. With seals in place put a thin ﬁlm of Dow #7 on the tops of the seals and the ﬂat surface of the discs. Prior to reinstalling the discs the drive shaft should be removed and the O-rings cleaned, inspected and lubricated with Dow #7. The shaft can then be installed into the disc prior to installation. With the outlet disc assembled to the shaft the orientation of the shaft to inlet disc can be assured by installing the set with the through hole on the outlet disc at the 6 o’clock position.

The easiest thing would be to remove both disc drives and assemble the outlet side ﬁrst. Then each disc could be ﬁtted on the shaft individually. At this point the transfer valve cap assemblies can be reinstalled.

stainless steel spring and the plastic spring support is in place attached to the inside of the cap assembly. Next you can wipe the outside edge of the O-ring on the cap and the inside mating area of the valve with a clean cloth & re-apply a thin layer of silicone lubricant like Dow #7.

CAUTION

NOTICE

Be careful and make sure the meter cable doesn’t get under the drive cap while tightening as it will result in damaging the cable.

Position the large white drive gear with the “A” pointing toward the 1 o’clock position and then press it onto the stainless steel drive shaft, make sure it snaps & locks into position.

NOTICE

The white drive gear is splined to the drive shaft and will only assemble in one orientation. Because of this it is not necessary that the discs and gear be exactly positioned, the positioning needs to be approximate but they have to ﬁt on the shaft.

Next install the larger black reducing gear onto the stainless steel shaft, then install the remaining smaller reducing gears from left to right. Re-install
