SCT1 Series
Water Softener & Carbon Filter Combo

Pre-installation Instructions

Description of the water treatment system
This combo filter / softener system includes a brine (salt) tank, a carbon filter media tank and a softener resin tank with a backwashing control valve. Incoming water flows into the control valve and is directed down through the carbon and then the ion exchange softening resin. The carbon adsorbs chlorine to remove taste and odor and to protect the softener resin. The softener resin exchanges the hardness ions for softer ions. The softened water then returns to the control valve where it is directed into the service lines. The SCT1 Series carbon filter / water softener is designed to be installed on chlorinated water supplies.
Periodically the control valve will go through a regeneration cycle. The frequency of this regeneration process will depend on the size of water softener, incoming water quality and amount of water used. This cycle is factory preset to begin at 2:00 A.M. At this time the control valve will draw the brine solution out of the salt tank and flush both the accumulated hardness and excess salt to the drain. The control valve will then put fresh water back into the salt tank to make brine for the next regeneration cycle.
Water Quality
The water should be tested to determine the concentration, or levels of the items listed below:
Hardness – Hardness in drinking water is defined as those minerals that dissolve in water having a positive electrical charge (cat ions). The primary components of hardness are calcium (Ca++) and magnesium (Mg++) ions. But dissolved iron (Fe++) and manganese (Mn++) also contribute to total “adjusted” hardness. Hardness produces scale, soap scum and white mineral deposits which shorten the life of water using appliances, plumbing and fixtures. Water that has less than 1 grain of hardness is considered to be “soft” water.
pH – A measurement of the acidity of the water. pH is reported on a scale from 0 to 14. Neutral water has a pH of 7.0, lower values indicate acidic water. If your pH is below 6.8 you may consider installing an acid neutralizer before the water softener to elevate the pH.
Iron – A naturally occurring metallic element. Iron levels in excess of 0.3 milligrams/liter (mg/l) combine with oxygen causing orange or red (rust) stains on plumbing fixtures. Iron exists in some water sources in clear water (ferrous) state, red water (ferric) state or bacterial form. Iron levels that exceed 2.0 mg/l require special ion exchange resin for reduction, or if bacterial or ferric (red water) iron is present or iron level exceeds 4.0 mg/l, an iron filter should be installed ahead of this water softener.
Manganese – A naturally occurring metallic element. Manganese levels as low as 0.05 milligrams/liter (mg/l) can combine with oxygen to cause dark brown or black staining on fixtures. Additionally, manganese can cause an odor in the water similar to a “rotten egg” smell. This water softener may reduce manganese as well as iron; however, an iron filter may be required in some cases.
Tannin – A naturally occurring humic acid. Tannin is caused by water passing through decaying vegetation.
Coffee and Tea are prime examples of tannin in water. Tannin levels as low as 0.5 milligrams per liter can cause a yellow discoloration in water. Consult your dealer for a system designed to remove both tannin and hardness.
Hydrogen Sulfide – A naturally occurring gas. Hydrogen sulfide, more commonly referred to as sulfur gas, causes a distinct odor similar to “rotten eggs.” Due to its gaseous nature, hydrogen sulfide must be tested at the well site within 1 minute of drawing the sample. If sulfur is present additional equipment will be required. Air injection iron filters can typically treat up to 2 milligrams per liter of sulfur gas if regenerated daily. Specialty units can reduce higher amounts. Although carbon can reduce some sulfur, that is not the intended use for SCT1 units.
Location Considerations
The proper location to install the water softener system will ensure optimum performance and satisfactory water quality. The following factors should be considered in selecting the location of the equipment.

1. The water softener and filter system should be installed after the water meter on municipal water.
   Operating pressure of the softener must be limited to within 30 – 100 psi range.

2. The water softener and filter system should be installed as close as possible (preferably within 15’) to an adequate floor or laundry drain capable of handling the backwash cycle volume and flow rate (refer to unit specifications).

3. All water conditioning equipment should be installed prior to the water heater.
   Water temperatures exceeding 100°F can damage the internal components of the control valve and filter tank. Install with at least 10’ of pipe before the water heater to prevent thermal damage to the equipment.
   Otherwise, an expansion tank may need to be installed in the line to the water heater in order to allow for thermal expansion and comply with local plumbing codes.

4. The water softener should not be subject to freezing temperatures.

5. Ensure that any cartridge or in-line type filter installed prior to the water softener does not restrict the water flow and pressure available for backwash and interfere with normal operation.

6. Appliances requiring extended periods of continuous or high flow water use (i.e. geothermal heat pumps, swimming pools, lawn irrigation, outside hose bibs, etc.) should bypass the water softener.

7. Consider installing a vacuum breaker to prevent damage to the mineral tanks in the event of a water main break or check valve failure in a well system.

General Installation

GENERAL INSTALLATION & SERVICE WARNINGS
The water conditioner is not designed to support the weight of plumbing.
Do not use Vaseline, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may be used on black “O” Rings. This will allow ease of installation and decrease chance of rolling from the bypass and tank connections. Avoid any type of lubricants, including silicone, on red or clear lip seals.
Do not use pipe dope or other sealants on threads. Teflon® tape may be used as required. Teflon® tape is not used on any connection where “O” Ring seals are used
The nuts and caps are designed to be unscrewed or tightened by hand or with the special plastic Service Wrench, (CV3193, not included). If necessary, pliers can be used to unscrew the nut or cap. Do not use a pipe wrench to tighten nuts or caps. Do not place screwdriver in slots on caps and/or tap with a hammer.
NOTE: If the plumbing system is used as the ground leg of the electric supply, continuity should be maintained by installing ground straps around any non-conductive plastic piping or bypass used in the installation.
Make sure the filter is not installed backwards. The filter will not function properly if installed backwards and filter media may be forced into the service lines. Arrows molded into the valve body and red handles of the bypass indicate the direction of flow.
All local plumbing codes must be followed.

Bypass Valve

The bypass valve is used to isolate the control valve from the plumbing system’s water pressure in order to perform control valve repairs or maintenance. The 1″ full flow bypass valve incorporates four positions including a diagnostic position that allows a service technician to have pressure to test a system while providing untreated bypass water to the building. Be sure to install bypass valve onto main control valve, before beginning plumbing or make provisions in the plumbing system for a bypass. The bypass body and rotors are glass filled Noryl® and the nuts and caps are glass filled polypropylene. All seals are self-lubricating EPDM to help prevent valve seizing after long periods of non-use. Internal “O” Rings can easily be replaced if service is required. The bypass consists of two interchangeable plug valves that are operated independently by red arrow shaped handles. The handles identify the direction of flow. The plug valves enable the bypass valve to operate in four positions.

1. Normal Operation Position: The inlet and outlet handles point in the direction of flow indicated by the engraved arrows on the control valve. Water flows through the control valve for normal operation of a water softener or filter. During the regeneration cycle this position provides regeneration water to the unit, while also providing untreated water to the distribution system (Fig. 2).

2. Bypass Position: The inlet and outlet handles point to the center of the bypass. The system is isolated from the water pressure in the plumbing system. Untreated water is supplied to the building (Fig. 3).

3. Diagnostic Position: The inlet handle points toward the control valve and the outlet handle points to the center of bypass valve. Untreated supply water is allowed to flow to the system and to the building, while not allowing water to exit from the system to the building (Fig. 4) . This allows the service technician to draw brine and perform other tests without the test water going to the building.
   NOTE: The system must be run through a rinse cycle before returning the bypass valve to the normal position.

4. Shut Off Position: The inlet handle points to the center of the bypass valve and the outlet handle points away from the control valve. The water is shut off to the building. The water treatment system will depressurize upon opening a tap in the building. A negative pressure in the building combined with the softener being in regeneration could cause a siphoning of brine into the building. If water is available on the outlet side of the softener it is an indication of water bypassing the system (Fig. 5)

Installation Instructions

STEP 1: Unpack SCT1 unit, making sure to remove entire contents of the shipping container prior to disposal.
STEP 2: Place the tanks in the upright position. Use the provided wrench to remove the fill port caps from the filter and softener tanks (See Figure 6a, page 7) by turning it counter-clockwise.
STEP 3: If media is not already loaded, use the provided funnel to pour carbon into the filter tank (left) and pour softener resin into the softener tank (right). At least 14” of space MUST be left empty at the top of the tank to allow for media bed expansion during backwash and to prevent media from being discharged to the drain or to the other tank.
STEP 4: Use a garden hose or bucket to fill the media tanks with water.
IMPORTANT: Carbon must be soaked for at least 2 hours prior to submitting it to full backwash flow rate to prevent loss of media to drain.
STEP 5: Clean fill port threads to remove any media. Lubricate the fill port cap o-ring with silicone grease.
Replace the fill port caps using the provided wrench.
STEP 6: Shut off all water at main supply. On private well system, turn off power to pump and drain pressure tank. Make certain pressure is relieved from complete system by opening nearest faucet to drain system. SHUT OFF FUEL / ELECTRICAL SUPPLY TO WATER HEATER.
STEP 7: Plumb the water supply line to the unit’s bypass valve inlet, located at the right rear as you face the unit. There are a variety of installation fittings available. They are listed under Installation Fitting Assemblies, pages 21-23. 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 solder flux, primer, and solvent cement on any part of the “O” Rings, split rings, bypass valve, or control valve. If the building’s electrical system is grounded to the plumbing, install a copper grounding strap from the inlet to the outlet pipe. Plumbing must be done in accordance with all applicable local codes. MAKE CERTAIN WATER ENTERS THROUGH INLET AND DISCHARGES THROUGH OUTLET.
STEP 8: Apply thread tape to DLFC Assembly. Remove drain line flow control (DLFC) retainer clip (Figure 6b, Page 7) and remove the DLFC assembly from the valve body, (Figure 6b, Page 7). Apply thread tape to threads. Slide drain fitting compression nut onto provided drain tubing and place the tube insert inside the end of the tubing. Insert tubing end with insert into drain elbow and tighten the compression nut onto the thread taped elbow. Reinsert DLFC assembly into the valve body, making certain it is FULLY inserted before replacing the retaining clip.
STEP 9: Install drain line. Use the provided ½” I.D. polyethylene tubing (DO NOT USE FLEXIBLE VINYL TUBING!) to run drain line from control valve DLFC fitting (Figure 6b, Page 7) to floor drain or sump pit capable of handling the backwash rate of the filter (refer to specifications and flow rate on page 17) or discard the compression fitting and use the ¾” NPT fitting to connect a rigid pipe drain line . If backwash flow rate is greater than 7.5 gpm, use existing NPT connector with rigid drain line. There must be an air gap at the end of the drain line to prevent siphoning of wastewater. Length of drain line should be 15’ or less. AVOID OVERHEAD DRAINS. STEP 10: With the bypass valve handles in the bypass position (Figure 3, Page 5), turn on water supply. Turn the inlet bypass valve handle to the diagnostic position (Figure 4, Page 5) and allow the unit to pressurize.
NOTE: the INLET and OUTLET knobs turn clockwise to close the port to the filter and counter-clockwise to open the port to the filter. Check for leaks and correct as needed. Return the inlet bypass valve handle to the bypass position.
STEP 11: Connect one end of the 3/8” brine line to the control valve quick connect brine refill elbow (Figure 6b, Page 7). Insert the other end of the brine line through the hole in the brine tank and into the quick connect fitting on the top of the safety brine valve (Figure 7). Remove the quick connect collet retainer clip (if included) before inserting the brine line into each fitting, press the tube in very firmly and replace the retainer clip behind the collet.
NOTE: THE BRINE TUBING SHOULD BE INSERTED 5/8” INTO THE FITTING. DO NOT PUT SALT INTO THE BRINE TANK AT THIS TIME. STEP 12: If desired, install overflow tubing (not provided) from overflow elbow on brine tank (Figure 7) to floor drain. Tubing must be lower than the overflow elbow at all times.
DO NOT CONNECT DRAIN LINE FROM SOFTENER CONTROL VALVE TO BRINE TANK OVERFLOW. DO NOT CONNECT BRINE TANK DRAIN LINE TO THE SOFTENER DRAIN LINE.
STEP 13: Plug the transformer into an un-switched electrical outlet. Ensure the control valve is in “Service” mode (time of day is displayed on the screen {refer to page 10 for General Operation}).
STEP 14: Place the bypass valve in the “Service” position (refer to Figure 2, Page 5; Figure 6a, Page 7) and open main supply valve or turn on power to pump on private well systems. Allow the unit to fill with water and pressurize, then place the bypass valve in the “Bypass” position (refer to Figure 3, Page 5).
STEP 15: Add water in the brine tank to slightly above the top level of the salt grid (approx. 6 gallons).
DO NOT ADD SALT TO THE BRINE TANK AT THIS TIME.
STEP 16: With the bypass valve in the “Bypass” position (refer to Figure 3, Page 5), press and hold the REGEN button until the motor starts. Then use the REGEN button to advance the control valve to the BACKWASH cycle (refer to page 12 for details) to release pressure and purge air from the mineral tank.
STEP 17: Refer to Page 5 for bypass valve operation. Rotate the INLET knob of the bypass valve slowly to the “Service” position. If any air spurts or any media is expelled to the drain, stop turning the knob until only water flows to the drain, then continue turning the knob fully to the “Service” position.
STEP 18: When all air has been purged from the system and only water is running to the drain, turn the OUTLET knob of the bypass valve to the “Service” position also. Allow the system to backwash for a several minutes or until the drain water runs clear.
STEP 19: Using the REGEN button, advance the control valve to the BRINE DN (downflow brine draw) cycle. Verify that the water level in the brine tank is slowly dropping (less than ½ gpm). Allow water level to drop below the top of the salt grid before continuing. If the water level does not drop, refer to page 15 for Troubleshooting. After verifying water level is dropping advance the control valve past the BACKWASH 2, RINSE AND 5 second FILL cycle to the time of day, using the REGEN button.
ADD SALT TO BRINE TANK NOW. Any type of water softener salt may be used.
STEP 20: Check for leaks and correct as necessary.
STEP 21: Turn power or fuel supply back on to water heater.
STEP 22: Press and hold the NEXT and UP buttons together until the screen changes to input the adjusted hardness level water (refer to Installer Settings, Page 11, for details), then press NEXT repeatedly until the time of day is displayed.
STEP 23: Press the CLOCK button to set the current time of day. (Page 10, note AM and PM).
STEP 24: Verify the meter is registers flow by opening a treated faucet and seeing that the word SOFTENING flashes on the display screen while water is flowing.

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 gallons remaining. This is the number of gallons that can be treated before the system needs to go through a regeneration cycle.
The user can scroll between the displays as desired. 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 flowing through the system) the word “SOFTENING” flashes on the display. 

Set Time of Day
Step 1 – Press CLOCK.
Step 2 – Current Time (hour): Set the hour of the day using ▲ or ▼ buttons.
AM/ PM toggles after 12. Press NEXT to go to step 3.
Step 3 – Current Time (minutes): Set the minutes of day using ▲ or ▼ buttons.
Press NEXT to exit Clock. Press REGEN to return to previous step.
Power Loss – Lithium battery on circuit board provides up to 8 hours of time clock backup during power outages.
After 8 hours, only the time of day needs to be reset, all other values are stored in non-volatile memory. If a power loss last less than 8 hours and time of day is flashing, replace coin type 2032 battery.
Do not forget to reset for daylight savings time

Installer Settings

Step 1 – Press NEXT and ▲ simultaneously for 3 seconds.
Step 2 – Hardness: Set the amount of adjusted hardness in grains per gallon (hardness gpg + (iron ppm x 3) + (manganese ppm x 5)) using ▲ or ▼ buttons. The default is 20 with value ranges from 1 to 150 in 1 grain increments. If this display shows “nA –“, then system is either set-up in “time clock” or “filter” modes. Press NEXT to go to Step 3. Press REGEN to exit Installer Settings.
Step 3 – Day Override: This sets the maximum number of days between regenerations. If value set to “oFF” regeneration is initiated automatically solely on gallons used.
If value is set as a number (allowable range from 1 to 28) a regeneration will be initiated automatically on that day even if metered gallon usage does not trigger a regeneration. Press NEXT to go to step 4. Press REGEN to return to previous step.
Step 4 – Regeneration Time (hour): Set the hour of day for regeneration using ▲ or ▼ buttons. AM/PM toggles after 12.
The default time is 2:00 a.m. This display will show “REGEN” on 0 GAL if system is set for immediate regeneration. Press NEXT to go to step 5. Press REGEN to return to previous step.
Step 5 – Regeneration Time (minutes): Set the minutes for the regeneration time using ▲ or ▼ buttons. This display will not be shown if system is set for immediate regeneration.
Press NEXT to exit Installer Displays/Settings. Press REGEN to return to previous step.

Regeneration Display
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 the household is asleep. If there is a demand for water when the system is regenerating, untreated water will be supplied. 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 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.
To initiate a manual regeneration at the preset delayed regeneration time, press and release REGEN. The words “REGEN TODAY” will flash on the display to indicate that the system will regenerate at the preset delayed regeneration time. 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 three seconds. The system will begin to regenerate immediately. The request cannot be cancelled. You must cycle all the way through the cycles to make it stop.
PLEASE NOTE: This will reset the meter. If back-to-back regenerations are desired, press and release REGEN button. “REGEN TODAY” will appear on screen. Push and hold REGEN button to initiate immediate regeneration. The softener will regenerate again at specified time. Back-to-back regenerations are recommended when salt is allowed to run out in brine tank. Make sure the brine tank contains salt before initiating a manual regeneration.

Maintenance

You will need to replace the carbon and gravel underbed at least every three years. Replacement may be required sooner if the taste and odor being removed begins to reappear in the treated water or you experience increasing pressure drop that is not resolved by increasing the frequency of backwashing.
TO REPLENISH OR REBED MEDIA:

1. Pressure must be relieved on the system by placing the Bypass Valve in the “Bypass” position (Figure 3, Page 5) and initiating a manual regeneration (section 3, page 12) and using the REGEN button to advance the control valve into a BACKWASH cycle.
2. Unplug the Control Valve from the electrical outlet to prevent it from advancing automatically.
3. Disconnect the filter tank fill port head at the union nuts.
4. Unscrew the filter tank head from the mineral tank and remove the distributor tube.
5. Siphon water from Mineral Tank. Remove existing media and gravel.
6. Rinse Mineral Tank and replace distributor, making certain that the distributor basket sits in the center of the tank bottom.
7. Cover the top of the distributor tube. Use a funnel to pour gravel and carbon into the mineral tank. Begin loading the tank with the gravel underbed. Filling the Mineral Tank 1/3 with water before loading gravel will cushion the fall and ensure even distribution of the gravel and media. At least 14” of space MUST be left empty at the top of the mineral tank to allow for media bed expansion during backwash and to prevent filter media from being discharged through the drain line.
8. Use a garden hose or bucket to fill the media tank with water.
9. Clean tank threads to remove any filter media. Uncover distributor tube and reinstall fill port head by threading it securely onto the mineral tank. Be careful not to cross-thread the tank. O-ring seal; HAND TIGHTEN ONLY!
10. Reattach fill port head at the union nuts.
11. IMPORTANT! Carbon must be soaked for at least 2 hours prior to submitting it to full backwash flow rate to prevent loss of media to drain.
12. Initiate Manual Regeneration (Backwash Cycle): With the bypass valve in the bypass position, press and hold the “REGEN” button until the drive motor starts. The drive motor will run briefly, and a count-down timer will appear in the lower right the display. Then press “REGEN” briefly at the countdown for both “FILL” and “SOFTENING” until the word “BACKWASH” appears in the upper left of the display and another countdown has begun.
13. Unplug the transformer from the electrical outlet to keep the SCT1 in backwash for an extended time to purge any air and remove media “fines” (very small particles of media).
14. Slowly turn the INLET knob of the bypass, counterclockwise, to a point approximately 1/3 of the way between “Bypass” and “Service” positions (Figure 2, Page 5) to release the remaining air from the tanks. Water should soon begin to flow (slowly) to the drain.
15. Once the air is purged, gradually turn the INLET knob of the bypass valve counterclockwise until it is fully in “Service” position (Figure 2, Page 5). Then turn the OUTLET knob of the bypass valve counterclockwise until it is fully in the “Service” position (Figure 2, Page 5). and leave the control valve in “Backwash” position for several minutes or until water flowing from the drain line runs clear.
16. Plug the transformer into the electrical outlet. Use the “REGEN” button to advance the control valve back to the service position where the time of day is displayed.
17. Full Manual Regeneration: Either press and hold the “REGEN” button to immediately initiate a full regeneration or briefly press the “REGEN” button to schedule a regeneration at the normal regeneration time. After this the filter will return to service mode automatically.
