Installation Guide

Preparation

1. Turn off the water supply to the toilet at the shut-off valve located near the base of the toilet.
2. Flush the toilet to empty the tank. Hold the handle down to drain as much water as possible.
3. Use a sponge or towel to remove any remaining water from the tank.
4. Disconnect the water supply line from the bottom of the fill valve.
5. Unscrew the nuts securing the toilet tank to the bowl and carefully lift the tank off. Place it on a protected surface.

Flush Valve Installation

6. Remove the old flush valve from the toilet tank. Clean the flush hole area thoroughly.
7. Place the new rubber grommet onto the base of the NuFlush canister flush valve. Ensure it is seated correctly.
8. Insert the flush valve into the 3-inch flush hole at the bottom of the toilet tank. Ensure the overflow tube is positioned correctly.
9. From the underside of the tank, secure the flush valve with the large plastic nut provided. Hand-tighten firmly, but do not overtighten.

12. Secure the fill valve from the underside of the tank with the plastic nut. Hand-tighten.
13. Adjust the height of the fill valve by twisting the upper section. The fill valve is adjustable from 7 to 14 inches to fit various tank heights. Ensure the critical level mark is above the overflow tube.

Tank Reassembly and Final Steps

14. Carefully place the toilet tank back onto the toilet bowl, aligning the bolt holes.
15. Insert the nylon bolts through the tank and bowl holes. Secure with washers and nuts from underneath the bowl. Tighten evenly until the tank is stable, but do not overtighten to avoid cracking the porcelain.
16. Reconnect the water supply line to the bottom of the fill valve. Hand-tighten, then use a wrench for a quarter turn to ensure a leak-free connection.
17. Slowly turn on the water supply. Allow the tank to fill. Check for any leaks around the connections and the base of the tank.
18. Test the flush mechanism.

Operating Instructions

The NuFlush Glacier Bay Replacement Flush Valve features a dual-flush mechanism, allowing for water conservation. The top button typically has two sections for different flush volumes:

• Partial Flush: Press the smaller button or the smaller section of the dual button for liquid waste. This uses less water.
• Full Flush: Press the larger button or the larger section of the dual button for solid waste. This uses the full tank volume.

Ensure the button is fully depressed and released for proper operation. The fill valve will automatically refill the tank to the set water level after each flush.

Maintenance

Regular maintenance helps prolong the life of your toilet components. The NuFlush flush valve is designed for easy seal replacement without needing to replace the entire valve.

• Cleaning: Periodically inspect the flush valve and fill valve for mineral buildup or debris. Clean with a non-abrasive cleaner and a soft brush if necessary.
• Seal Replacement: If you notice a slow leak or constant running water from the flush valve, the seal may need replacement. The canister design allows for easy removal and replacement of the bottom seal. Refer to the manufacturer's guidelines for specific seal replacement procedures.
• Fill Valve Adjustment: If the water level in the tank is too high or too low, adjust the fill valve height as described in the installation section.
