3. Einrichtung und Installation
Follow these steps for proper installation of your FluidMaster 747 Fill Valve:
- Wasserzufuhr abstellen: Locate the water shut-off valve for your toilet, usually near the base, and turn it clockwise until the water flow stops.
- Leerer Zisternenraum: Flush the toilet to drain the water from the cistern. Hold the flush handle down to ensure as much water as possible is removed.
- Altes Ventil entfernen (falls zutreffend): Disconnect the water supply line from the old fill valve. Unscrew the locknut from underneath the cistern that secures the old valve, then remove the old valve.
- Insert New Valve: Place the FluidMaster 747 fill valve into the hole at the bottom of the cistern. Ensure the shank is properly seated.
- Sicheres Ventil: From underneath the cistern, thread the provided locknut onto the valve shank and tighten it by hand. Do not overtighten, as this can damage the cistern or valve.
- Wasserversorgung anschließen: Attach the water supply line to the brass connector (G 3/8" x 35 mm) at the base of the new fill valve. Tighten securely by hand, then use a wrench for a final quarter-turn, being careful not to overtighten.
- Höhe anpassen: The valve's height can be adjusted by twisting the upper section or using the water level adjusting screw (refer to product diagrams). Adjust the valve so that the critical level mark is above the overflow pipe.
- Wasserversorgung wiederherstellen: Slowly turn the water shut-off valve counter-clockwise to restore water flow to the cistern. Check for any leaks around the connections.
- Wasserstand anpassen: Allow the cistern to fill. If the water level is too high or too low, fine-tune the float mechanism using the water level adjusting screw until the desired water level is achieved (typically about 1 inch below the top of the overflow pipe).

4. Bedienungsanleitung
The FluidMaster 747 Floating Fill Valve operates automatically. Once installed and the water supply is turned on, the valve will sense the water level in the cistern. After each flush, as the water level drops, the float mechanism will activate the valve, allowing water to refill the cistern to the pre-set level. The valve will then shut off, maintaining the desired water volume for the next flush.
Ensure the water level is adjusted correctly during installation for optimal flushing performance and water conservation.
5. Wartung
The FluidMaster 747 valve features a self-cleaning mechanism designed to minimize the need for frequent maintenance. However, periodic checks can help ensure its longevity and efficient operation:
- Regelmäßige Inspektion: Periodically inspect the valve for any signs of wear, debris, or mineral buildup, especially in areas with hard water.
- Reinigung: If you notice slow filling or reduced performance, turn off the water supply and gently clean any visible debris from the valve's inlet screen or float mechanism.
- Vermeiden Sie scharfe Reinigungsmittel: WARNUNG: Do not use in-tank, drop-in toilet bowl cleaners containing bleach or chlorine. Use of such products can result in damage to tank components and property, and may void the Fluidmaster warranty. Always use quality Fluidmaster parts when installing or repairing.
