Fleck 7000SXT Installation Guide

This is only a general instruction reference, be sure to read your owners manual for any special instructions on your particular softener.   

Notice: consumer is responsible for following any state and/or local regulations and plumbing codes pertinent to the purchase, installation and operation of our products.

Aplus Water LLCalways recommends that you have a licensed plumber install your water softener.

Step 1:
Location of your softener is important. It should be in a protected dry, level and non-freezing area
(34-120 degrees F). The 2 tanks should be set close to each other. The square tank is your salt (brine) tank (for softener salt or potassium chloride) and it is the tank that you will have to refill sometimes, so make it the more accessible of the 2 tanks. Do not put salt in this tank until you have put the softener into service and have tested the cycles.

Step 2:
You will need a standard outlet that is not controlled by a switch.

The distributor tube is on the left and should be placed in the middle bottom of the resin tank with the white end down.  BEFORE ADDING THE RESIN!


Step 3:
Place the resin tank shown above where you want to connect it to your water line, because it will be hard to move after the resin is added.  Place the  distributor tube into the bottom middle of the resin tank (the taller of the two tanks and shown in the picture above). 

Place a peace of tape on the open end of the distributor tube to keep any resin from falling into the distributor while pouring the resin into the mineral tank (unless a plug is already in place).

Place the funnel (provided) into the mineral tank, and begin to pour or scoop the resin into the mineral tank. NOTE: if you recieved gravel add the gravel first then the resin.  (most applications do not require gravel).

Be careful to keep the distributor tube centered as best you can, while filling.  An easy (but slower) way to fill the mineral tank is to take a small scoop and pour the media into the funnel. The media beads tend to stick to the funnel so by filling slowly the media will go into the tank easier.

note: if you have been shipped more then one bag of resin.  The resin is the same in each bag so you can pour it, in any order.

Once the filling of the mineral tank is completed, carefully remove the tape or plug from the distributor tube. Do not pull upwards on the distributor tube.

Step 4:

Remove white cap and plug from riser tube on tank.

The control valve (head) now must be screwed onto the mineral tank. Be sure the large O-ring is in place, and lubricated (you can use standard cooking oil to lubricate if necessary).  As you start to screw the control valve onto the tank, make sure the hole in the center of the control valve fits over the distributor tube.

DO NOT USE pipe dope or tape on the threads! The control valve should be hand tightened, snugly, clockwise. (DO NOT OVER TIGHTEN VALVE!!!!)

Step 5.

 You are now ready to install the bypass valve to the control valve. 

Step 6:
Turn off main water valve.  Water connections to and from softener should now be connected.  

NOTE: Attach the inlet to the bypass with the arrow pointing in and the outlet to the arrow pointing out!

Step 7:
You will need a drain for the backwashing cycles. This should be no longer than 20 feet from the softener.  You will need to purchase this flexible 1/2 i.d. plastic pipe (can be vinyl, polyethylene polybutylene, etc. and same size will be used in step 8) and a small clamp to hold the tubing over the fitting. This backwashing drain line will be under pressure when the backwash cycle is working. Make sure the drain line is secured. The drain line will need to drain into a drain, which should be a minimum of 1 1/2” size, and ideally be below the top of the head of your softener. Local codes should be adhered to.  Also, do not put the drain line directly into any drain, you should have an air gap. (be sure to use teflon tape on this step).

This is where you will connect the drain line.

Note: Never connect the drain line directly into a drain. Allow an air-gap between the drain line and waste line to prevent possibility of back- siphon.

Step 8:
a.Between the valve and the salt tank you will need to connect the furnished 3/8” O.D. tubing to the controller with compression nut and safety float with the push fitting. 

b. Take the cap off the white tube inside the salt tank pictured below. 

note: if overflow is not installed already now is the time to do it because it holds the brine well to the salt tank.


Connect the 3/8 inch tubing by pushing it into the quick connect elbow in the brine tank.

or the compression fitting depending on the type you received.


You will be attaching the other end of the tubing and nut to the smaller of the two threaded drains on the controller. Pictured below.

Step 8:
Salt tank Overflow (this is the elbow on the side of your salt tank).  Attach 1/2" i.d. plastic tubing to the fitting from the salt tank and run to a drain. This drain line will not be under pressure. DO NOT tie into the backwash drain line! This line should be higher than your drain line. Overflow drain line must be a separate line from fitting to the floor-drain, sewer, tub, etc.


1.Add water to the salt tank. With a bucket or hose, add approximately 1 to 2 gallons of water to the salt tank.

2.Set your bypass in bypass mode and slowly turn on the main water valve to your home until all pipes are pressurized. Now open the bypass on the inlet side SLOWLY by placing a screw driver between the two holes on the knob, you will hear the water softener filling up with water. You do not want to be surprised by leaks. Let the resin tank fill completely, then SLOWLY open the bypass on the outlet side.  Turn on a nearby faucet until the water runs clears and then turn it off.  This is to remove trapped air from the softener.

WARNING: If opened too rapidly or too far, media may be lost out of the tank into the valve or the plumbing. In the 1/4 open position, you should hear air slowly escaping from the valve drain line.

3. Plug the power supply transformer into a socket that is not controlled by a switch or timer.

4.Program your water softener.  Follow the insert in your owners manual or click on the link below.

Programming Insert

Note: only tap the regeneration button to toggle between steps in programming, if you hold it down for too long it will go into a regeneration.

Set Time of Day Display to 12:01 P.M. by pushing the down or up arrow.

Push and hold the Set Up and Set Down buttons for 5 seconds.

Press the Extra Cycle Button once per display until all displays are viewed and normal operation is resumed.

Option setting display may be changed as required by pushing either the Set Up or Set Down button.
Depending on current valve programming,
certain displays may not be viewed or set.

The default for step 4 is c-24 which stands for 24,000 grains you will need to change that to your system capacity.  Check examples below.  So if you bought a 48,000 grain system you need to change that number to 48.

** FOR 24,000 GRAIN CAPACITY, c-24

STEP 7 - REGENERATION DAY OVERRIDE -We recommend 10 days. A--10.


5.Once your softener is programmed advance your controller to manual regeneration. The regeneration process is a 1 to 2 hour process.

6.Check for any leaks during this initial regeneration.  Also make sure that there is water in the salt tank after the regeneration is complete.

7.Your softener is now in operation and you can add salt.

 Note: Be sure to always have at least one bag of salt in the brine tank at all times.  You may fill the salt tank all the way up if you like.   Standard water softener salt works well.
