Safety Information

This water conditioner’s control valve conforms to UL/CE Standards. Generic valves were tested and certiﬁed for compliance as veriﬁed by the agency listing.

• Please review the entire Installation and Operation Manual before installing the water conditioning system.

• As with all plumbing projects, it is recommended that a trained professional water treatment dealer install the water conditioning system. Please follow all local plumbing codes for installing this water conditioning system.

• This system will not make microbiologically unsafe water safe. Water that is unsafe must be treated separately from this conditioner.

• This water conditioning system is to be used only for potable water.

• Inspect the water conditioning system for carrier shortage or shipping damage before beginning installation.

• Use only lead-free solder and ﬂux, as required by federal and state codes, when installing soldered copper plumbing.

• Use caution when installing soldered metal piping near the water conditioning system. Heat can adversely affect the plastic control valve and bypass valve.

• All plastic connections should be hand tightened. Teﬂon® tape may be used on connections that do not use an O-ring seal. Do not use pipe dope type sealants on the valve body. Do not

use pliers or pipe wrenches.

• Do not use petroleum-based lubricants such as Vaseline, oils or hydrocarbon-based lubricants. Use only 100% silicone lubricants.

• Use only the power transformer supplied with this water conditioning system.

• All electrical connections must be completed according to local codes.

• The power outlet must be grounded.

• Install an appropriate grounding strap across the inlet and

outlet piping of the water conditioning system to ensure that a proper ground is maintained.

• To disconnect power, unplug the AC adapter from its power source.

• Observe drain line requirements.

• Do not support the weight of the system on the control valve

ﬁttings, plumbing, or the bypass.

• Do not allow this water conditioning system to freeze. Damage from freezing will void this water conditioning system’s warranty.

• Operating ambient temperature: 34° to 120°F (1° to 49°C).

• Operating water temperature: 34° to 100°F (1° to 38°C).

• Operating water pressure range : 25 to 120 psi (1.38 to 8.27

bar).

• Observe all warnings that appear in this manual.

• Keep the media tank in the upright position. Do not turn upside

down or drop. Turning the tank upside down or laying the tank on its side can cause media to enter the valve.

• Use only regenerants designed for water conditioning. Do not use ice melting salt, block salt or rock salt. During cold weather it is recommended that the installer warm the valve to room temperature before operating. Teﬂon® is a trademark of E.I. duPont de Nemours.

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® Silicone Compound (available from 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.

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 ﬁlter media/ softening resin 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 125psi (8.6 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 buy all local, city, and state codes. Use a 3/4" drain line for backwash ﬂow rates that exceed 7 gpm or length that exceeds 20' (6 m).

8. For softening systems, 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 and follow 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 air can be purged from the tank.

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. Check for leaks and repair as needed.

16. 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.

7 W110 LXT Downﬂow Softeners and SXT Filters

Timer Operation LXT

A. Meter Delayed Control

A Meter Delayed Control measures water usage. The system regenerates at the programmed regeneration time after the calculated system capacity is depleted. The control calculates the system capacity by dividing the unit capacity by the feedwater hardness and subtracting the reserve. The reserve should be set to insure that the system delivers treated water between the time the system capacity is depleted and the actual regeneration time. A Meter Delayed control will also start a regeneration cycle at the programmed regeneration time if a number of days equal to the regeneration day override pass before water usage depletes the calculated system capacity.

B. Control Operation During Regeneration

During regeneration, the control displays a special regeneration display. In this display, the control shows the current regeneration step number the valve is advancing to, or has reached, and the time remaining in that step. The step number that displays ﬂashes until the valve completes driving to this regeneration step position. Once all regeneration steps are complete the valve returns to service and resumes normal operation.

The meter and time clock controls will use and display cycles:

1. Backwash

2. Brine/Slow Rinse

3. Rapid Rinse

4. Brine Tank Reﬁll The ﬁlter controls will use and display cycles:

1. Backwash

2. Rapid Rinse Pressing the Extra Cycle button during a regeneration cycle

immediately advances the valve to the next cycle step position and resumes normal step timing.

E. Control Operation During A Power Failure

The LXT includes integral power backup. In the event of power failure, the control shifts into a power-saving mode. The control stops monitoring water usage. The display and motor shut down, but it continues to keep track of the time and day for a minimum of 12 hours.

The system conﬁguration settings are stored in a non-volatile memory and are stored indeﬁnitely with or without line power.

If power fails while the unit is in regeneration, the control will save the current valve position before it shuts down. When power is restored, the control will resume the regeneration cycle from the point where power failed.

CAUTION

If power fails during a regeneration cycle, the valve will remain in it’s current position until power is restored. The valve system should include all required safety components to prevent overﬂows resulting from a power failure during regeneration.

The control will not start a new regeneration cycle without line power. If the valve misses a scheduled regeneration due to a power failure, it will queue a regeneration. Once power is restored, the control will initiate a regeneration cycle the next time that the Time of Day equals the programmed regeneration time. Typically, this means that the valve will regenerate one day after it was originally scheduled. If the treated water output is important and power interruptions are expected, the system should be setup with a sufﬁcient reserve capacity to compensate for regeneration delays.

C. Control Operation During Programming

The control only enters the Program Mode with the valve in service. While in the Program Mode, the control continues to operate normally monitoring water usage and keeping all displays up to date. Control programming is stored in memory permanently, and does not rely on battery backup power.

D. Manually Initiating a Regeneration

1. When timer is in service, press the Extra Cycle button for 5 seconds on the main screen.

2. The timer advances to Regeneration Cycle Step #1 (backwash), and begins programmed time count down.

3. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #2 (brine draw & slow rinse).

4. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #3 (rapid rinse).

5. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #4 (brine reﬁll).

6. Press the Extra Cycle button once more to advance the valve back to in service.

NOTE: If the unit is a ﬁlter or upﬂow, the cycle step order

Timer Operation SXT

A. Meter Immediate Control

(Not used on SXT ﬁlter systems.) A Meter Immediate control measures water usage and regenerates

the system as soon as the calculated system capacity is depleted. The control calculates the system capacity by dividing the unit capacity (typically expressed in grains/unit volume) by the feedwater hardness and subtracting the reserve. Meter Immediate systems generally do not use a reserve volume. The control will also start a regeneration cycle at the programmed regeneration time if a number of days equal to the regeneratio day override pass before water usage depletes the calculated system capacity.

B. Meter Delayed Control

(Not used on SXT ﬁlter systems.) A Meter Delayed Control measures water usage. The system

regenerates at the programmed regeneration time after the calculated system capacity is depleted. As with Meter Immediate systems, the control calculates the system capacity by dividing the unit capacity by the feedwater hardness and subtracting the reserve. The reserve should be set to insure that the system delivers treated water between the time the system capacity is depleted and the actual regeneration time. A Meter Delayed control will also start a regeneration cycle at the programmed regeneration time if a number of days equal to the regeneration day override pass before water usage depletes the calculated system capacity.

C. Time Clock Delayed Control

A Time Clock Delayed Control regenerates the system on a timed interval. The control will initiate a regeneration cycle at the programmed regeneration time when the number of days since the last regeneration equals the regeneration day override value.

D. Day of the Week Control

This control regenerates the system on a weekly schedule. The schedule is deﬁned in Master programming by setting each day to either "off" or "on". The control will initiate a regeneration cycle on days that have been set to "on" at the speciﬁed regeneration time.

E. Control Operation During Regeneration

Pressing the Extra Cycle button during a regeneration cycle immediately advances the valve to the next cycle step position and resumes normal step timing.

F. Control Operation During Programming

G. Manually Initiating a Regeneration

1. When timer is in service, press the Extra Cycle button for 5 seconds on the main screen.

2. The timer advances to Regeneration Cycle Step #1 (backwash), and begins programmed time count down.

3. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #2 (brine draw & slow rinse). Not used on SXT ﬁlter systems).

4. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #3 (rapid rinse).

5. Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #4 (brine reﬁll). Not used on SXT ﬁlter systems.

6. Press the Extra Cycle button once more to advance the valve back to in service.

NOTE: If the unit is a ﬁlter or upﬂow, the cycle step order

may change.

NOTICE

H. Control Operation During a Power Failure

The SXT includes integral power backup. In the event of power failure, the control shifts into a power-saving mode. The control stops monitoring water usage. The display and motor shut down, but it continues to keep track of the time and day for a minimum of 12 hours.

The system conﬁguration settings are stored in a non-volatile memory and are stored indeﬁnitely with or without power. The Time of Day ﬂashes when there has been a power failure. Press any button to stop the Time of Day from ﬂashing.

CAUTION

The control will not start a new regeneration cycle without power. If the valve misses a scheduled regeneration due to a power failure, it will queue a regeneration. Once power is restored, the control will initiate a regeneration cycle the next time that the Time of Day equals the programmed regeneration time. Typically, this means that the valve will regenerate one day after it was originally scheduled. If the treated water output is important and power interruptions are expected, the system should be setup with a sufﬁcient reserve capacity to compensate for regeneration delays.
