4.5 Adjusting Flush Volume

The flush volume can be adjusted between 6 and 9 liters. Refer to the internal mechanism for specific adjustment points, typically a lever or screw on the flush valve. Adjust according to your preference for water conservation.

4.6 Final Checks

1. Slowly turn on the main water supply and allow the cistern to fill.
2. Check all connections for any signs of leakage.
3. Perform several test flushes to ensure proper operation and water flow.

5. Operation

5.1 Flushing with Start-Stop Function

The Geberit AP 110 cistern is equipped with a start-stop flush function. Press the flush button once to initiate the flush. To stop the water flow prematurely and save water, press the flush button a second time. This allows for flexible water usage based on need.

6. Maintenance

6.1 Cleaning

Clean the exterior of the cistern regularly with a soft cloth and mild, non-abrasive cleaning agents. Avoid harsh chemicals that could damage the plastic surface. The cistern is UV-resistant, helping to maintain its white finish over time.

6.2 Internal Components

The cistern is sweat-water insulated, which prevents condensation from forming on the exterior. Periodic inspection of internal components for wear or mineral buildup is recommended, especially in areas with hard water. If any internal parts require replacement, use genuine Geberit spare parts.

7. Troubleshooting

• Cistern not filling: Check if the water supply valve is fully open. Ensure the flexible hose connection is not kinked or blocked.
• Continuous water flow into the toilet bowl: This usually indicates an issue with the flush valve or the fill valve. Inspect for debris or wear.
• Leaks: Check all connections for tightness. If leaks persist, turn off the water supply and inspect seals and gaskets.
• Excessive noise during filling: While the AP 110 is designed to be low-noise, unusual sounds may indicate a problem with the fill valve. Ensure water pressure is within recommended limits.

For persistent issues, it is advisable to contact a qualified plumber or Geberit customer support.
