Setup and Installation
The Geberit Delta50 actuator plate is designed for front actuation and tool-free, fast adjustment. Follow these steps for proper installation:
- Prepare the Cistern: Ensure the concealed cistern is correctly installed and the water supply is off.
- Attach Mounting Frame: Secure the provided mounting frame to the cistern according to the cistern's specific instructions. Ensure it is level and flush with the finished wall surface.
- Insert Distance Bolts: Insert the distance bolts into the designated holes on the mounting frame. These bolts help position the actuator plate correctly.
- Connect Actuator Rods: Attach the actuator rods to the flush mechanism of the cistern. These rods transmit the force from the buttons to the flush valve. The rods are designed for tool-free adjustment.
- Mount Actuator Plate: Carefully align the Delta50 actuator plate with the mounting frame and the actuator rods. Press the plate firmly into place until it clicks securely. Ensure the buttons align with the actuator rods.
- Test Functionality: Turn on the water supply and test both flush buttons to ensure smooth operation and proper water flow. Adjust the actuator rods if necessary to achieve optimal flush performance.

Operating Instructions
The Geberit Delta50 Actuator Plate features a dual-flush mechanism, allowing for two different flush volumes to conserve water.
- Full Flush: Press the larger button for a full flush, typically used for solid waste.
- Reduced Flush: Press the smaller button for a reduced flush, suitable for liquid waste.
The actuation force required is less than 20 N, ensuring a gentle push is sufficient to operate the desired flush volume.
Maintenance
To maintain the appearance and functionality of your Geberit Delta50 Actuator Plate, follow these cleaning guidelines:
- Regular Cleaning: Clean the surface regularly with a soft, damp cloth and a mild, non-abrasive cleaning agent.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, or strong chemical detergents, as these can damage the chrome finish.
- Fingerprints: The matt chrome finish may show fingerprints. Wipe with a soft cloth to restore its appearance.
- Inspection: Periodically check the actuator rods and mounting frame for any signs of wear or looseness.
