Before You Begin

Basic plumbing skills are required for installation. If you are unsure of your abilities to install the system using these instructions please hire a qualified plumber.

Read through your parts list and verify all components are accounted for and in good condition BEFORE scheduling a plumber.

Please read through the entire instruction manual carefully. If hiring a plumber ensure they have a copy before they start.

Most common questions are answered in the instructions or FAQ section. If you have read both of those and still have questions you may contact us for further help.

Plumbing related questions need to be directed to a locally qualified plumber. We are not plumbers and any plumbing questions we receive will not be answered.

System Requirements

Your chosen installation location and water supply must meet ALL of the following requirements:

  1. Verify System Inventory

Use the following table to help verify the parts that are included with your system and verify that they are all accounted for. Inspect all parts for damage and report any damage immediately. Damage claims must be made within 30 days of delivery to be eligible for replacement.

Resin/Media Tank
Polyglass Tank
A tall slender tank 44–65 inches in height with an opening on the top. Larger tanks may have a gray threaded adapter to reduce tank opening to match control head.
Note for loaded systems: Tanks that are shipped loaded may arrive on their side or even upside down. The tanks are closed and the resin will return to the bottom once place in the correct position. Any mixing of tank contents will correct itself after being placed in service.
Distributor Tube
Riser/Distributor Tube
A tall pipe that runs from the bottom of the tank to the control valve. If your tank is loaded (empty tanks only weigh 20-30 pounds) DO NOT pull the riser tube out of the tank. One end has a basket (basket design varies) and it usually ships inside the tank.
Fleck 5600 and 5600SXT
Control Head
Screws on top of the tank and controls the water flow and regeneration cycles. Digital SXT has LCD panel. The mechanical has control knobs.

Please note: Some SXT systems may have labels referring to the older SE model number. This is an internal designation and does NOT indicate that you received an SE controller. This image will show the differences for easy reference.
Brine Tanks with Float
Brine Tank
A large plastic tank (round OR square/rectangular) similar to a trash can. Inside the tank is the brine well—a small cylinder about 4 inches (10.1 cm) in diameter—which contains the saftey float. The brine tank holds the salt (not included) used for regeneration. There will also be an overflow fitting and tubing. Some systems may have a salt grid—a plastic grid on the bottom of the tank—but most do not as they are not needed when using salt pellets as recommended. This tank holds the salt, DO NOT load the resin in brine tank.
Connection Options
Bypass Valve
Depending on your order your system will have either a single piece stainless steel bypass or a two part plastic bypass with yoke connection. This is what connects to your control head and provides standard fitting connections to hook up to your plumbing.
Fleck meter assemblies
Meter Assembly
The flow meter connects the control head and the bypass valve and it measures the water flow to initiate regeneration on demand. Includes O-rings (already attached) to seal the connection and screws and clips to secure the connection. Typically connected to the control head when received.
Brine Fittings
Brine Connection Parts
Tubing and fittings used to connect the control head to the brine tank. Tubing is usually inside the brine tank, the fittings are usually in a small bag, either with the tubing, with the instructions, or with the control head. Fittings include the brass brine nut, ferrule, insert, and screen.
Drain Fittings
Drain Fitting
Fitting(s) that connect the control head to the drain line. Please Note: Drain line is not included. Depending on the system ordered there are multiple options, and the pictures shown are common examples but actual fitting may vary.
Unloaded systems only
Most systems will ship loaded. Some larger systems may ship partially loaded (with some media in the tank and some separate) or completely unloaded for easier placement.
Garnet and Gravel
Small rocks or pebbles to promote water distribution. Most systems use standard gravel, but very large systems will use the denser garnet gravel. Gravel goes in first, at the bottom of polyglass tank.
Softening Resin
Bag(s) of material placed in the polyglass tank that does the actual treatment of the water. Color of resin may vary
Please Note: Depending on system size you may receive more than one package of resin packaged differently. This is normal. The system is designed to use all the resin shipped with it, however, sometimes a resin bag can be overfilled. To avoid problems, do not fill the tank more than 3/4 full. The system needs the space at the top of the tank for proper regeneration, and overfilling the tank may lead to improper system operation.
The funnel is a complementary item that MAY be included with some unloaded systems to help fill the polyglass tank with the resin. If your system does not include one, a blender pitcher with the blade assembly removed will screw onto the tank and work well.

Depending on system size you can see what tank size and resin amounts you will receive:

Tank Size and Resin Qty
Standard Capacity 16k 24k 32k 40k 48k 64k 80k 96k 110k
Tank (in inches) 8 x 44 8 x 44 9 x 48 10 x 44 10 x 54 12 x 48 13 x 54 14 x 65 14 x 65
Resin 0.5 ft³ 0.75 ft³ 1.25 ft³ 1 ft³ 1.5 ft³ 2 ft³ 2.5 ft³ 3 ft³ 3.5 ft³

Before you start plumbing

  1. Pre-installation preparation

Money-saving tip: If hiring a plumber to do the installation you can save some money by preparing the tank ahead of time. This cuts down on the time the plumber has to spend and doing so is simple enough that most people can accomplish it in less than an hour.

  1. Verify riser tube position
Tank & Riser
Tank & Riser

NOTE REGARDING LOADED TANKS: Systems that arrive loaded will have the riser tube in place and attempting to remove it will require the tank to be emptied and refilled. DO NOT try to remove the riser tube from a loaded tank.

The riser tube sits in an indentation centered in the bottom of the tank. With the riser tube properly positioned, ensure that it is within 1/3 inch (8 mm) above or below the lip of the tank. If it is not contact us for help correcting the problem.

If your system came loaded - Skip down to the section titled "Finish filling the tank with water".

If your system was not loaded or partially loaded - Continue to the next step.

  1. Fill tank partially with water Optional

This optional step will help buffer the resin as it is poured in and will also help minimize air bubbles upon initial startup. Simply pour water into the tank until it is 1/4 - 1/3 filled with water.

  1. Load resin and gravel—gravel goes in first

The resin goes in the polyglass tank, DO NOT load the resin in brine tank

Tank with funnel
Tank with Funnel

Make sure to cover the opening of the riser tube. Simply put something over the end of the tube such as a piece of tape, to prevent anything from falling into the riser tube.

If you have gravel with your system it will go in first! Make sure to empty all boxes to verify it is not in the bottom of the tank box or in a box with the resin.

When filling the tank, do so slowly and ensure the riser tube stays correctly positioned and centered in the tank. If you have more than one bag of resin, after gravel the order does not matter and all of it should be used. Once all the resin is loaded the tank will not be completely full, this is normal.

  1. Finish filling tank with water Optional

Once the resin is loaded you may finish filling the tank with water. This can help reduce air bubbles and ease initial startup.

  1. Attach the Control Head
  1. Lubricate the O-rings DO NOT use Vaseline
Tank O-ring
Tank O-ring
Pilot O-ring
Pilot O-ring

The tank O-ring——seals the control valve to the tank, and the pilot O-ring——seals around the riser tube. Verify they are present and free from nicks or kinks. Use a silicone lubricant or vegetable oil to both O-rings. DO NOT use petroleum based lubricants! Please note that the pilot O-ring is up inside the control head and you will usually have to reach up inside to feel it. It is very secure inside the head and almost impossible for it to come out. It is also a good idea to verify that the riser tube fits snugly into the pilot hole and that the O-ring seals around it.

  1. Inspect and install top distributor basket if applicable
Top Distributor Basket
Top Distributor Basket
Top Distributor Basket Attached Top Distributor Basket

Depending on system configuration your system may include a top distributor basket—. If your system includes one it is recommended that you use it. If you do not have one then it is not needed. If you do have one the larger end will fit inside the bottom of your control valve, with the smaller end sliding over the riser tube pointing down into the tank—. Please note that locking tabs hold it in place so a fair amount of force is needed to install or remove it.

  1. Screw on control head hand tight only

DO NOT apply anything (pipe dope, plumbers paste, Teflon tape, etc.) to the threads on the control head or the resin tank!

Ensure the riser tube slips inside the pilot opening in the bottom of the head. Screw the head down onto the resin tank until solid contact is made between the tank and O-ring, then tighten about another 1/4–1/3 of a turn and STOP. Do not over tighten the control head as this can cause damage. Once properly tightened down check to ensure the tank and control head meet evenly all the way around.

  1. Prepare and Connect Brine Tank
  1. Assemble the brine tank
Unassembled Brine Tank
Unassembled Brine Tank
Assembled Brine Tank
Assembled Brine Tank

The brine tank will come with the brine well loose, either inside the brine tank or in the box with the brine tank—. You will use the overflow fitting to attach it in the side of the brine tank, placing the overflow fitting through the lower hole on the brine tank and securing it through the brine well with the nut—. If you are having a hard time fitting your hand between the float and the brine well to secure the overflow nut you can remove the float by removing the nut that holds the float in place. Make sure to put it back when you are finished. Please Note: Some systems may use a compression style float fitting that will look different than the style shown, but will function the same way.

  1. Use 3/8 inch line to connect brine tank to control head
5600 Brine Fitting
Brine Fitting
Brine Line Fittings
Brine Line Fittings

The brine line will connect from the brine fitting on the control head——to the fitting on the float inside the brine tank. To attach it to the float put the tubing through the hole in the brine tank and push the tubing into the fitting until in stops, then push a little harder to get it to lock in place. To remove the tubing, hold the collet ring that sits around the tubing while pulling the tubing out. The other end of the tubing will connect to the control head. Place the fittings on the tubing as shown——and connect it to the control head. Please Note: If your brine tank uses the compression style fitting it will connect to the brine tank in a manner similar to how it connects to the control head.

  1. Connect overflow to floor drain Optional

If you have a floor drain available you can connect the overflow fitting to it using a flexible line. Do not connect the overflow to the drain line from the control head or run the line above the level of the overflow outlet.

  1. Add salt to the brine tank, water is not necessary

Add salt to the brine tank. We recommend high quality salt pellets designed for water softeners for the best results. You will need to add at least one bag of salt and can fill it up to the top of the brine well. Ensure there is salt in the brine tank at all times. You do NOT need to add water to the brine tank. The resin is precharged and able to treat the water out of the box and the initial regeneration ran after installing the system will place the initial volume of water in the brine tank.

  1. Setup Control Head
  1. Plug control head in

Plug the control head into a qualifing outlet as stated in the requirements section. Please Note: The control head can be plugged in and operated without water, this will not damage the control head. Once plugged in, verify the system is receiving power and ensure the outlet is not on a switch that might get turned off. On digital valves the display should light up and start flashing a time, on mechanical valves you may hear a quiet hum of the motor or you may have to wait to see if the time dial keeps track of time. Please note: The service icon (the icon that looks like a faucet) indicates that the system is IN SERVICE, that is the system is running and working. It DOES NOT indicate the system needs serviced.

  1. DIGITAL CONTROLLER - Inital valve setup

If you have the mechanical valve skip the digital controller sections and proceed with the mechanical setup

SXT Display
SXT Controls

For initial programming enter master programming by setting the clock to 12:01 pm. To set the time of day press and hold the up OR down arrow until the service icon is replaced with the programming icon. Use the up and down arrows to set the time of day (PM is indicated in the upper right corner of the screen). Hold the arrow button to advance quickly through the time. Once the time is set, press the extra cycle button to save the setting. Once the parameter display is gone, press and hold the up AND down arrow buttons together for 5-10 seconds until the programming icon appears and [DF] is shown in the parameter code. Once each setting has been entered, use the extra cycle button to advance to the next setting. Please Note: Most of these settings will be left alone.

Depending on your system some settings may not be shown, and some settings may be different than shown here. Do not change any settings unless specifically instructed to do so by these instructions or one of our techs.

VariableThis setting will vary depending on the system and application. Use these instructions to set appropriately.
PLEASE NOTE:Any setting on your system that is not specifically highlighted below will be left at default. This is a list of all possible options, and many will NOT be shown on your system and are included for informational purposes only.
Code Parameter Options Description
DF Display Format GAL Volume is displayed in gallons and time in a 12-hour AM/PM format - These instructions are based on the GAL setting
Ltr Volume is displayed in liters and time in 24-hour format
VT Valve Type dF1b Downflow single backwash - used on softeners that require the brine draw.
Fltr Filter - used for basic backwashing systems that do not need the brine draw
dF2b Downflow double backwash - similar to the dF1b but with 2 backwashes. Not commonly used.
UFbd Upflow brine first - not commonly used.
UFtr Uplow filter - not commonly used.
Othr Other - not commonly used
CT Control Type FI Metered (Flow) Immediate - counts down from the programmed gallon capacity and begins a regeneration immediately after reaching 0. Only used on dual tank water softeners.
Fd Metered (Flow) Delayed - counts down from the programmed gallon capacity and when 0 is reached queues a regeneration cycle for the set regeneration time. Only used on water softeners.
Tc Time Clock - will begin a regeneration cycle at the set regeneration time after the set number of days has passed. Common setting on all backwashing systems except water softeners to ensure consistent cleaning of the media.
dAY Day of the Week - will begin a regeneration cycle on the set day(s) at the set regeneration time. More consistent Time Clock setting is recommended in most situations.
NT Number of Tanks 1 For systems with only 1 media tank (all systems except dual tank softeners).
2 For systems with 2 media tanks (dual tank softeners only).
UT Indicates current tank in service U1 Tank 1 is in service
U2 Tank 2 is in service (dual tank softeners only).
C Capacity 1-999.9
System capacity, in grains. Metered softeners only. This will be set to match your system size, so a 48k or 48,000 grain system will be set to 48. Reference the tank size chart above for help in matching up your tank size with capacity.
H Hardness 1-199 Hardness of the water, in grains. Metered softeners only. Hardness, this is the hardness of the water as measured in grains per gallon (GPG). If your test shows hardness as parts per million (ppm) or milligrams per liter (mg/l) simply divide by 17.1 to get grains per gallon.
RS Reserve Selection SF Percentage saftey factor - this uses a percentage of the capacity for a reserve. Softener systems only. A fixed reserve is recommened over this setting.
rc Fixed reserve capacity - uses a set volume for a reserve. Softener systems only. This is the recommended setting for softeners.
SF Saftey Factor 0-50% Only applies to softeners with RS set to SF
RC Reserve Capacity 1-(half of calculated capacity) Fixed reserve capacity, softeners only. This is the number of gallons the system reserves as a saftey factor to ensure the system will treat the water until the next regeneration. It is commonly set to the average number of gallons used in a day. If you are unsure of your actual usage, a good rule of thumb is to set it to the number of people in the house times 75. Example, if there are 4 people in the house, you would set it to 300 gallons (4x75).
DO Day Override 14 This setting will start the regeneration cycle after the set number of days regardless of water usage. Typically set to 14 or less to ensure the resin gets lifted and cleaned off regularly. This ensures effective filtration and long resin life.
RT Regen Time 2:00 This sets the time that the regeneration cycle will start. This process can take up to 2 hours depending on system size and configuration, so schedule it when water will not be used. It is common to set to run when everyone is asleep or out of the house, and ensure it does not conflict with any other systems you may have.
BW Backwash 10 This sets the length of the backwash portion of the cycle. During this cycle water flows through the system in reverse to lift the resin and rinse off accumulated contaminants, with a strong flow of water going out the drain line. Reducing this cycle can lead to reduced resin life and premature system failure. For very dirty water longer times may be needed.
BD Brine Draw 60 This sets the length of the brine draw portion of the cycle. During this cycle the water from the brine tank is rinsed slowly through the resin tank to regenerate the resin. A slow flow of water will go down the drain during this cycle, and the brine tank will be emptied. Please note: The brine tank will typically empty fairly quickly, with significant time remaining in the cycle, this is normal as the remaining portion of the cycle is used to saturate the resin with the solution to ensure effective regeneration.
RR Rapid Rinse 10 The rapid rinse cycle runs water through the tank in the normal direction to rinse off any excess salt and settle the resin for normal operation. During this cycle there will be a steady flow of water down the drain.
BF Brine Fill 12 This sets the length of the brine fill portion of the cycle. During this cycle the system will put water into the brine tank. Please note: The brine tank will have water in it after this cycle completes and it will remain in the tank until the next regeneration, this is normal. Exact amount will vary, and water level in the brine tank may be above OR below the salt level depending on system, brine tank, and amount of salt in the tank.
D1-D7 Day of the Week Setting OFF Set to On or OFF for each dayof the week. Only applies to systems with Control Type dAY, not typically used.
CD Current Day 1-7 Used to set the current day. Only applies to systems with Control Type dAY, not typically used.
FM Flow Meter Type P0.7 3/4" Paddle Wheel Meter For the larger domed meter used on most softeners.
Gen Generic or Other Meter
P2.0 2" Paddle Wheel Meter
t1.5 1.5" Turbine Meter
P1.5 1.5" Paddle Wheel Meter
t1.2 1.2" Turbine Meter
t1.0 1" Turbine Meter
P1.0 1" Paddle Wheel Meter
t0.7 3/4" Turbine Meter For the smaller meter used on some softeners. Not as common as the paddle wheel meter.
K Meter Pulse Setting 0.1-999.9 Pulses per gallon. Only applies to systems with FM set to Gen, not typically used.
Pressing the extra cycle button after the final setting will save your changes. If no buttons are pressed for 60 seconds while in programming mode the changes will be cancelled.
If you accidentally change a setting that does not have a recommended or variable value: Please do a hard reset as outlined in the resets section to return all values to default. You can then go back through the programming to set it up according the the chart above.

Once you have finished programming use the arrows to set the current time of day. Once the time is set the display should then show the service icon, with the data display flashing between the current time of day and remaining system capacity. As water flows through the system the flow indicator will flash and the system capacity will count down. Once it reaches 0 the system will queue a regeneration for the set time. A flashing service icon indicates that a regeneration is queued. A manual regeneration can be queued by pressing the extra cycle button. An immediate regeneration can be initiated by holding the extra cycle button for about 5 seconds. The service icon indicates that the system is "In Service" and functioning correctly, it does NOT mean that the system needs service.

After intial setup the master programming should not need to be used again unless a system reset is performed. Even in the event of a power outage all settings are retained. If your water use or water quality changes you can use the user programming to make common changes to the programming as lined out below.

  1. DIGITAL Controller - Resets

If your controller is showing odd behavior such as erratic display, no display, or showing an error code, the first step is to try and reset it. Start with the soft reset, and if that does not solve the problem move on to the master reset. If the problem persists contact one of our technicians.

SXT Controller Resets
Reset Directions Effect
Soft Reset Hold Extra Cycle and Down buttons for 25 seconds This will reset all parameters to the system default values, but leaves the volume remaining intact. This is a good place to start if you feel you may have changed a default setting. After resetting proceed through the master programming section.
Hard Reset Hold Extra Cycle button while plugging the unit in This will reset all parameters in the system. This is typically reserved for erratic behavior that a soft reset does not resolve. After resetting proceed through the master programming section.

You will need to calculate the gallon capacity of your system (how many gallons the system can go through before it needs to regenerate). To calculate this number you will need to know the system capacity, (for example, a 48k system has a 48,000 grain capacity) and the hardness of the water in grains per gallon (GPG). If your test shows hardness as parts per million (ppm) or milligrams per liter (mg/l) simply divide by 17.1 to get grains per gallon. Take the capacity of the system and divide by this number, this is your total capacity. Multiply the number of people in the house by 75, this is your reserve capacity. Subtract the reserve capacity from the total capacity and this is how many gallons you will set your system to. The gallon capacity of the system is denoted by a gear with the numbers 1-21, these numbers represent the number of gallons x 100 that you system is set to regenerate at. To set your system, pull out the capacity knob and rotate the knob until the correct number is lined up with the white dot. As an example, if the water hardness is 24 GPG and you have a 48k system with 3 people, your gallon capacity would be (48,000/24)-(75x3)=1775 gallons. You would line the white dot up between the numbers 17 & 18. You can use the chart below to help. If unsure of the size of your system you may contact us for assistance. Be sure to include the name the system was ordered under when contacting us. If your water is extremely hard or if you have high water use a larger reserve capacity may be needed.

To set the time, locate the 24 hour time gear (the large gear located behind the manual cycle knob) and note the current time arrow. Push the red time set button in and rotate the 24 hour time gear until the current time arrow lines up with the current time of day. A white arrow will point at the current gallon capacity remaining. Once the countdown reaches zero the system will run a regeneration cycle that night at midnight or 2 AM (depending on the system, the time is usually indicated on a label located on the back of the valve). During regeneration there should be no water being used, and the default time is usually fine for most homes. To have it run at a different time (for example if you work late and are up and using water at the default time) you will need to adjust the current time of day to trick the system into doing so at the desired time. For example: if the system is set to run at 2 AM and you want it to run at 8 AM, set the current time of day 6 hours behind, that way the system will think it is 2 AM when it is actually 8 AM.

Plumbing the system in

  1. Plumbing Guidelines

Before you continue Many homeowners install their own water systems with basic plumbing skills; if you are not comfortable with projects like this, please hire a professional plumber. Make sure to check local plumbing codes and follow any codes that apply. These intructions offer basic plumbing tips and can not cover every situation. They are intendend as a supplement and should not replace local plumbing codes or actual plumbing experience.

  1. Drain Line Connection

Please note: Drain water comes out under line pressure, so it can be run vertically to connect to an overhead drain pipe.

Drain Fitting

Example Drain w/ Air Gap

Never make a direct connection into a waste water drain. A physical air gap of at least 3 inches (76 mm) between the end of the drain line and the wastewater level in the drain pipe should be used to avoid contamination of the line. An additional gap of 3/4 inch (19 mm) between the drain pipe and drain line is recommended to prevent any problems in the case of a pipe overflow. Using a simple P-trap as shown——is ideal as well, but a stand pipe with a diameter of at least 1.5 inches (38 mm) is adequate. As the water coming out is under pressure, make sure to secure the drain line so that it does not move and create a mess.

Do not tie multiple systems into a single drain line.
If hooking up multiple systems, each system needs a separate, independent drain line to ensure proper operation and prevent damage. Systems can all be run to the same standpipe/sump/outside drain, but the drain line from each system needs to be separate.
Do not use additional fittings on the drain line.
Avoid installing any additional fittings (check valves, ball/gate valves, etc.) as this can prevent proper backwash and cause premature system failure.

  1. Inlet/Outlet Connections
Connection Options
Connection Fitting

Do not overtighten the screws. The bypass valve will have some up and down movement, this is normal. The clips simply hold the connection fittings together and the screws only need tightened enough to keep the clips in place. Further tightening will not stop leaks and tightening too much can damage the system, which will not be covered under warranty. The meter assembly is expensive to replace, so extra care is recommended on these systems.

Verify flow direction. Untreated water will enter the system on the side marked with an arrow pointing toward the front of the control head (on both the bypass valve and the control head itself). Treated water will exit the system on the side marked with an arrow pointing away from the front of the control head (on both the bypass valve and the control head itself).

Correct inlet/outlet connections are vital. Improper flow direction will prevent proper operation and can damage your system and your plumbing. The direction of flow can not be changed. Turning the bypass upside down will not change the direction of the water flow.

Bypass position
Bypass Position

It is recommended to keep the bypass in the service position when making plumbing connections and turn it to bypass when first turning the water back on. shows the bypass position. In bypass position the handles will be turned 90-degrees and be perpendicular to the inlet and outlet fittings.

When soldering do not solder directly to the included connection or close to the control control head. First solder a short (min 3-inch [7.6-cm]) piece of copper pipe onto the adapters, away from the valve, before connecting the adapter to the bypass or yoke fitting.

For threaded connections, do NOT tighten the adapters into fittings while they are connected to the control head. Disconnect the bypass or yoke fitting, and connect the adapter using a high quality thread sealant (pipe joint compound or Teflon/PTFE tape), and replace.

When installed the bypass valve can move up and down, this is normal.

  1. Place System in Service

Once all plumbing is done and plumbing connections have been checked for leaks you can place the system in service.

  1. Open bypass valve slowly

If you have more than one system, enure the other systems are bypassed to prevent any possible problems. Open a faucet that is near the system, a laundry sink or outside faucet (if it will be treated by the system) is ideal, this will allow the air to bleed out of the system. Slowly open up the bypass valve just to the point of allowing water to enter the system at a trickle, and leave it like that until the tank is full of water. If you prefilled the system it should only take a minute or two. Once the tank is full, slowly open the bypass valve the rest of the way. Allow water to run out of the faucet for 15-20 minutes to ensure all the air is worked out of the tank and off of the , then close the faucet.

  1. Check for leaks

Check the system for any leaks, paying attention to the seal between the tank and control head as well as the connections between the bypass valve and control head. Open a nearby faucet and check to ensure there is no leaks that show up when water is running.

  1. Flush the system

Open a nearby faucet. The water may be discolored at first, this is normal. Let water run out of the faucet for at least 10 minutes, or until any discoloration clears up. Depending on the system this may be almost immediate, or it may take a couple of hours. Once the water is cleared up a manual regeneration should be run.

  1. Initiate manual regeneration

It is a good idea to allow the system to run through a manual cycle. On mechanical valves, turn the main knob until it clicks into the first position. On digital systems, hold the extra cycle button for 5-10 second until the backwash starts.

  1. Verify proper operation

Watch the system as it steps through each cycle, make sure it moves to each position, that water is not leaking from any other fittings, and that water is flowing down the drain line. The brine line will have water flowing through it during the appropriate cycles as well. Please Note: Digital systems only With the brine tank empty the system will not draw water out of the brine tank during the brine draw cycle. This cycle can be skipped during the initial startup by pressing the extra cycle button after the [BD] cycle has started counting down. The resin is precharged and the brine water is not needed for the first cycle, the initial cycle is run to ensure the brine tank has the correct amount of water for the first automatic cycle.

Be sure to return any other systems to the service position.

Frequently Asked Questions

Inventory and Setup

What is the proper order to arrange multiple systems?

If you are installing more than one tank system the typical order for installation is:
sediment filter > pH filter > iron filter > carbon filter > water softener > arsenic filter
Whole house cartridge systems are typically installed after any tank systems, the Scale Sentry system after the cartridge system(s), and any UV systems will be last.

Do I need a prefilter?

In most cases a prefilter is not necessary. Since the system cleans itself most particulate in the water will be trapped and rinsed off by the regeneration cycle, eliminating the need for a sediment prefilter. If you have a lot of sand in the water a spin down filter (part #SDF-100) is recommended to protect the control head - For water supplies with high levels of chlorine a carbon prefilter is recommended to extend resin life.

My polyglass tank arrived and sits crooked, what do I do?

The black boot on the bottom of the tank may get knocked out of alignment during shipment. If your tank is a bit tilted, simply pick the tank up 2–3 inches (5–8 cm) off the floor and drop it gently but firmly down, favoring the side that needs to be adjusted to make the tank stand straight.

I have read or seen that I shouldn't install the top distributor basket, is that true?

The top distributor basket is used to help prevent resin from getting up into the control head and into your pipes, it also keeps the resin from going down the drain during water or air surges. While systems that are installed correctly and fuctioning properly will not have issues, the top basket is included as a saftey measure to prevent problems and it is recommended to use it if present. Those who recommend leaving it off usually do so to prevent buildup on that basket that can lead to flow restrictions (more common in high iron waters), but it is usually easier to clean or replace a top basket periodically than cleaning out clogged fixtures if something does go wrong.

After installing the bypass it still moves up and down, is that normal?

Yes. The bypass seals with O-ring and even when tightened down some movement will occur, without leaking. The system requires this movement to allow for pressure changes in the system. Do not overtighten the bypass valve. As long as the screws are snug enough to keep the bypass from coming apart further tightening will just cause damage.

Drain Line

Can I run my drain line to a sewer/septic?

Yes. These systems can be ran to your sewer or septic line and is typically the recommended place to run the drain. Most concerns are related to the amount of water going down the drain, and a properly designed septic/sewer system will not have a problem handling it. Studies have also shown that concerns over salt in the wastewater affecting septic systems are unfounded and not a problem.

Can my drain line be ran vertically?

Yes. Water from the drain comes out under pressure and can be ran vertically if needed.

Digital Display

Why does my display flashing between the time of day and a number?

This is normal, with the number displayed indicating the number of gallons until the next regeneration.

What does the faucet icon mean?

That is the service icon, meaning the system is in service. It does NOT mean the system needs service. If it is flashing then a regeneration is queued for the next set time.

What does the water drop icon mean?

That is the flow icon. Only used on metered softners, it indicates water is flowing through the system.

What does the circled exclaimation icon mean?

That indicates an error. Match the number on your display with the number on the error chart below for troubleshooting tips.

SXT Error Codes
Error Code Error Type Cause Solution
0 Cam Sense Error Piston took more than 6 minutes to advance Unplug the system, disconnect the piston from the motor/gear, and verify that the piston moves freely inside the valve; if it does not replacement of the seal and spacers and possibly the piston is required. After reconnecting the piston, inspect the control head for any broken, worn, or disconnected parts, and replace or reconnect any that are found. Perform a hard reset. After verifying programming run the system through a regeneration and watch the motor to ensure that it is moving the piston, if it is not the motor needs to be replaced. If error still occurs contact us for support.
1 Cycle Step Error Unexpected cycle input Unplug the system and check to ensure all electrical connections and cam switches are secure. Plug the unit back in and check the master programming and ensure valve type and system type are correct for your system. Initiate a manual regeneration and verify it progresses through the steps correctly. If error reoccurs, contact us for support.
2 Regen Failure More than 99 days since last regeneration (7 on day of the week setups) Perform a manual regeneration to reset the error. Check your settings to ensure the system is setup to regeneration automatically. Check the meter to ensure it is not stuck and that the gallons remaining is counting down.
3 Memory Error Circuit board memory failure Perform a hard reset and go through the master programming to update the settings. If error occurs again contact us for support
UD Upper Drive Sync Piston is syncing Common when changing programming or if system looses power. System will automatically recover from this state.

Brine Tank

Is there supposed to be water in the brine tank?
How much water is supposed to be in the brine tank?

During normal operation the system will have water in the brine tank so that it can dissolve the salt needed for the next regeneration. The amount of water in the brine tank will vary depending on brine tank size, system size, control head configuration, system settins, and how much salt is in the brine tank. Depending on those factors the water level in your brine tank may be only a few inches high or it may be close to the overflow.

How much salt should I put in the brine tank?

You can fill the brine tank with as much salt as it will hold up to the top of the brine well. At a minimum there should be enough salt for the next regeneration, the amount needed will vary depending on system size and settings, but 1-2 bags of salt (40-80 pounds) will cover most systems.

How often do I need to add salt to the brine tank?

The rate at which you use salt will vary depending on system size, settings, water quality, and water use. It is your choice to add salt freqently to keep the brine tank full or only add salt when it starts to get low. Average homes will use 1-2 bags (40-80 pounds) of salt per month. Homes with high hardness or high water usage can expect higher salt usage.
