Core System Features
- Dual Valve Core Design: Equipped with two distinct valve cores. One core manages the water inlet and brine draw, while the other isolates the water outlet and controls drainage, ensuring zero untreated hard water leakage during service.
- Hermetic Ceramic Seals: Utilizes highly durable, scratch-resistant ceramic moving discs. This structural choice minimizes friction, prevents scaling within the valve body, and dramatically extends service life.
- Multi-Function Operation: Automatically routes fluid pathways to handle service, backwash, brine draw, slow rinse, brine refill, and fast rinse cycles.
- Filter Valve Conversion: By blocking the brine line connector and removing the drain connector, the F111A3 can be modified via its programming to act as a standard backwashing filter valve. ]
- Smart Interface & Safety: Features a clear LED digital screen with an automatic keypad lock to prevent accidental setting modifications. It retains program memory and parameters automatically following a power failure.
