Setup and Installation
Follow these steps for proper installation of your Geberit AP110 cistern:
- Preparation: Turn off the main water supply to the toilet. Drain any remaining water from the existing toilet tank. Remove the old cistern if applicable.
- Mounting the Cistern: Position the new Geberit AP110 cistern on the wall. Use the provided fixing kit to securely mount the cistern. The mounting points offer some flexibility to align with existing drill holes if replacing an old unit.
- Install Stopcock: Attach the stopcock to the water inlet on the cistern. Ensure it is tightened securely to prevent leaks.
- Connect Water Supply: Connect your external tap and connection hose (not supplied) to the stopcock. Hand-tighten first, then use a wrench for a final snug fit, being careful not to overtighten.
- Install Rinse Curve: Attach the rinse curve to the cistern outlet and connect it to the toilet bowl inlet. Ensure all seals are correctly seated to prevent leaks between the cistern and the toilet bowl.
- Final Checks: Slowly turn on the main water supply. Allow the cistern to fill. Check all connections for any signs of leakage.
- Test Flush: Perform several test flushes to ensure the cistern fills and flushes correctly without issues.

Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your cistern:
- Cleaning: Clean the exterior of the cistern with a soft cloth and mild, non-abrasive cleaning agents. Avoid harsh chemicals or abrasive scrubbers that could damage the surface.
- Internal Components: Periodically inspect the internal components for mineral buildup or wear. If necessary, turn off the water supply, drain the cistern, and clean or replace worn parts.
- Leak Checks: Regularly check for any signs of leaks around the cistern, connections, and the toilet bowl. Address any leaks promptly to prevent water damage.

Troubleshooting
Here are solutions to common issues you might encounter:
- Cistern not filling: Check if the main water supply is turned on. Ensure the stopcock is fully open. Inspect the fill valve for obstructions or damage.
- Cistern continuously running: This usually indicates a faulty fill valve or flush valve seal. Turn off the water supply, drain the cistern, and inspect or replace the affected components.
- Weak flush: Ensure the water level in the cistern reaches the correct mark. Check for any obstructions in the rinse curve or toilet bowl.
- Leaks: Tighten all connections. Inspect seals (e.g., between cistern and toilet bowl, or around the stopcock) for wear or improper seating and replace if necessary.
