3. Installation
Installation of the Fleck 5600SXT valve requires basic plumbing knowledge. It is recommended to consult a qualified plumber if you are unsure about any steps. Ensure the main water supply is turned off before beginning installation.
- Prepare the Tank: Ensure your water softener tank is properly prepared and free of debris. The valve is designed for tanks up to 13 inches in diameter.
- Attach the Yoke: Connect the included 3/4" MPT Yoke to your existing plumbing. Ensure all connections are secure and leak-free.
- Mount the Valve: Carefully mount the Fleck 5600SXT control valve onto the water softener tank. Hand-tighten first, then use a wrench to secure, being careful not to overtighten.
- Connect Drain Line: Attach the drain line to the appropriate port on the valve. Ensure the drain line has an air gap and is routed to an approved drain.
- Connect Brine Line: Connect the brine line from the salt tank to the valve.
- Electrical Connection: Plug the power adapter into a standard electrical outlet.
- Check for Leaks: Slowly turn on the main water supply and check all connections for leaks.
- DLFC Configuration: The valve comes pre-programmed for a 9-inch tank. If you have a larger tank, you may need to switch out the Drain Line Flow Control (DLFC) and reprogram the unit. Refer to the detailed programming instructions for your specific tank size.

4. Operating Instructions
The Fleck 5600SXT valve operates automatically once properly installed and programmed. The digital display provides key information about your water softener's status.
- LCD Display: The LCD screen on the control head will alternate between displaying the current time of day and the volume of soft water remaining (or days remaining) until the next regeneration cycle.
- On-Demand Regeneration: The paddlewheel meter continuously monitors your water usage. When the pre-set capacity is reached, the valve will initiate a regeneration cycle automatically. This ensures that regeneration only occurs when needed, conserving water and salt.
- Manual Regeneration: In some cases, you may need to initiate a manual regeneration. Refer to the detailed programming guide for instructions on how to perform a manual regeneration.
- Setting Time: If power is lost, the time of day may need to be reset. Follow the instructions in the programming guide to adjust the clock.
5. Maintenance
Regular maintenance helps ensure the efficient and long-lasting performance of your Fleck 5600SXT valve.
- Salt Level: Regularly check the salt level in your brine tank and replenish as needed. Ensure the salt remains above the water level.
- Clean Brine Tank: Periodically clean the brine tank to prevent salt bridging and sludge buildup, which can affect regeneration efficiency.
- Inspect Connections: Annually inspect all plumbing connections for any signs of leaks or corrosion.
- Valve Head Inspection: While the Fleck 5600SXT is designed for durability, if you notice any unusual noises, leaks from the valve head itself, or inconsistent soft water, it may indicate an internal issue. Contact support for assistance.
