2. Package Contents
The CORNAT AP3200 YIN Cover Plate package typically includes:
- 1 x CORNAT AP3200 YIN Cover Plate (White, Plastic)
- Mounting hardware (screws, rods, or clips, depending on the specific cistern model)
- Installation instructions (this manual)
Note: This cover plate is designed to be compatible with CORNAT concealed cisterns, specifically matching elements VWC352 and WEK2. Ensure your cistern is compatible before installation.
3. Installation Instructions
Installation of the CORNAT AP3200 YIN Cover Plate requires access to the concealed cistern frame. It is recommended to have basic plumbing knowledge or consult a professional for installation.
- Preparation: Ensure the cistern is correctly installed within the wall and the flush mechanism is accessible. Identify the mounting points for the cover plate on the cistern frame.
- Attach Actuator Rods/Pins: Depending on your cistern model, attach the provided actuator rods or pins to the flush mechanism. These rods will connect the cover plate buttons to the flush valve. Adjust their length according to the cistern manufacturer's instructions to ensure proper flush activation.
- Position the Cover Plate: Carefully align the CORNAT AP3200 cover plate with the mounting frame of the cistern. Ensure the actuator rods pass through the designated holes on the back of the cover plate.
- Secure the Cover Plate: Once aligned, secure the cover plate to the cistern frame using the provided screws or clips. Tighten them gently to avoid overtightening, which could damage the plastic. The plate should sit flush against the wall.
- Test Functionality: Press both the small (reduced flush) and large (full flush) buttons on the cover plate to ensure they activate the flush mechanism correctly and return to their original position smoothly. Adjust actuator rod lengths if necessary.
For detailed cistern-specific installation, refer to the instruction manual provided with your CORNAT concealed cistern (e.g., VWC352 or WEK2).
4. Operating Instructions
The CORNAT AP3200 YIN Cover Plate features a dual-flush system designed for water efficiency.
- Reduced Flush: To activate a reduced flush (e.g., for liquid waste), press the smaller section of the circular button, indicated by a single wave icon.
- Full Flush: To activate a full flush (e.g., for solid waste), press the larger section of the circular button, indicated by a double wave icon.
Ensure the button is pressed firmly and released to allow the flush mechanism to complete its cycle.
5. Care and Maintenance
To maintain the appearance and functionality of your CORNAT AP3200 YIN Cover Plate, follow these care instructions:
- Cleaning: Clean the surface regularly with a soft, damp cloth and mild soap. Avoid abrasive cleaners, scouring pads, or harsh chemicals (e.g., ammonia-based cleaners, bleach) as these can damage the plastic finish.
- Avoid Scratches: Do not use sharp objects or tools on the cover plate surface.
- Inspection: Periodically check that the cover plate is securely mounted and that the flush buttons operate smoothly.
6. Troubleshooting
If you encounter issues with your CORNAT AP3200 YIN Cover Plate, consider the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Flush button does not activate flush. | Actuator rods are too short or misaligned. | Remove the cover plate and adjust the length of the actuator rods according to your cistern's instructions. Ensure they are correctly seated in the flush mechanism. |
| Flush button sticks or does not return. | Actuator rods are too long, causing binding, or debris is obstructing the button. | Remove the cover plate and shorten the actuator rods slightly. Clean any debris around the button mechanism. |
| Cover plate is loose on the wall. | Mounting screws/clips are loose. | Gently tighten the mounting screws or re-secure the clips. Do not overtighten. |
If the problem persists after attempting these solutions, it may indicate an issue with the cistern's internal mechanism. In such cases, it is advisable to consult a qualified plumber or the cistern manufacturer's support.
