Key Considerations for the Swap:
* Physical Fit: Both valves use the standard 2.5-inch tank opening, allowing for direct replacement.
* AIO Components: The 5600 SXT AIO valve requires an inlet check valve (air injector) to operate correctly.
* Media Change Required: A standard filter valve typically operates as a simple backwasher (e.g., carbon, sediment), while an AIO valve is designed for specialized oxidizing media to remove iron and sulfur.
* Programming Changes:
The valve must be reprogrammed for air injection, including setting the backwash (BW) time to 15 minutes, adding a rapid rinse (RR) of 1–5 minutes, and turning the brine fill (BF) off.
*
Steps for Replacement:
1. Bypass the system and unplug the control valve.
2. Remove the old valve and securely attach the new 5600 SXT AIO valve, ensuring the riser tube is properly sealed.
3. Install the air check coupler on the inlet side.
4. Program the controller (see specific steps for AIO model ).
5. Initiate a manual backwash to check for leaks and ensure proper air draw.
The Fleck 5600SXT AIO (Air Injection Oxidizer) system is designed for backwashing oxidizing media to remove iron/sulfur.
It is NOT compatible with, or restricts the use of, media requiring consistent, heavy,
or specialized filtration methods like
high-density Filox, standard water softener resin (as a filter), or excessive, dense mixed-media beds.
What it IS Compatible With:
* Catalytic Carbon (Centaur/Filtrasorb)
* Birm (If pH is >6.8 and oxygen is present)
* Filter-Ox
* Katalox Light
* Multimedia blends (Birm, Calcite, Carbon, Filter AG)
Key Compatibility Notes:
* Backwash Requirement: The media must be backwashable.
* System Limitation: The AIO 5600 SXT usually handles a maximum of 1 cu ft of filter media effectively.
* Capacity Constraint: If your application requires more than 1 cu ft of media, the system may be too small.
FREQUENTLY ASKED QUESTIONS
Q: Does a system with the Fleck AIO Valve get installed before or after the softener?
A: The system with the Fleck AIO Valve should be installed before the softener. This ensures the softener and other filter systems are protected by filtering contaminants before the water goes into the softener to be softened.
Q: What control meters are compatible with the Fleck AIO Valve?
A: The Fleck AIO Valve is available with the Fleck SXT controller only.
Q: How do systems with the Fleck AIO Valve treat iron, manganese, and sulfide?
A: The valve utilizes an air injection system to remove iron (ferrous or clear water), manganese, and sulfur from the water via both oxidation and filtration.
Q: What is oxidization?
A: Oxidation is the loss of electrons during a reaction by a molecule, atom, or ion. In this process a substance is changed because of the addition of oxygen. When an iron object is oxidized, it goes from a strong metal to a red powder.
Q: Are chemicals necessary to reduce contaminants when the Fleck AIO Valve is used?
A: No, because it is using the oxidation process to remove contaminants (oxidation).
