Operating Instructions

The Geberit Samba Dual Flush Actuator provides two flush options for water efficiency.

• Full Flush: Press the larger of the two circular buttons for a full flush, typically used for solid waste.
• Half Flush: Press the smaller of the two circular buttons for a reduced flush, suitable for liquid waste, conserving water.

Ensure the buttons are pressed firmly and released to allow the flush mechanism to reset completely.

Maintenance

Regular cleaning and inspection will help maintain the appearance and functionality of your Geberit Samba Dual Flush Actuator.

Cleaning:

• Use a soft, damp cloth and a mild, non-abrasive cleaner.
• Avoid using harsh chemicals, abrasive pads, or cleaners containing ammonia, bleach, or alcohol, as these can damage the chrome finish.
• Wipe the surface gently to remove fingerprints, water spots, and dust.
• Dry the surface immediately with a clean, soft cloth to prevent water spots.

Inspection:

• Periodically check the flush buttons for smooth operation and ensure they return to their original position after being pressed.
• Inspect the plate for any signs of damage or loose connections.

Troubleshooting

If you encounter issues with your Geberit Samba Dual Flush Actuator, consider the following common solutions:

• Buttons Sticking or Not Actuating:
  • Ensure the actuator plate is correctly seated and not obstructed.
  • Check if the actuation rods are properly connected and not bent or damaged.
  • Clean around the buttons to remove any debris that might be causing sticking.
• Poor Flush Performance:
  • This is often related to the cistern mechanism, not the actuator plate itself. Refer to your Geberit cistern manual for troubleshooting flush issues.
  • Ensure the actuation rods are correctly adjusted to fully engage the flush valve.
• Actuator Plate Feels Loose:
  • Verify that the mounting frame is securely attached to the cistern.
  • Ensure the actuator plate is properly clipped into the mounting frame.
• Scratches or Damage to Chrome Finish:
  • Avoid using abrasive cleaners or tools. Minor scratches may be polished with specialized chrome polish, but deep scratches may require replacement.

If problems persist after attempting these troubleshooting steps, contact Geberit customer support or a qualified plumber.
