4.2 Installation Steps
- Prepare the Installation Area: Turn off the main water supply. Remove any existing shower components if replacing.
- Position the Riser Pipe: Hold the riser pipe assembly against the wall at the desired height. Use a spirit level to ensure it is perfectly vertical. Mark the positions for the wall brackets.
- Mount Wall Brackets: Drill holes at the marked positions. Insert wall plugs. Secure the wall brackets to the wall using the provided screws. The variable design allows adjustment to align with existing drill holes within a certain range.
- Attach Riser Pipe: Secure the riser pipe assembly to the mounted wall brackets. Ensure it is firmly held.

- Install Overhead Shower Head (if applicable): If you are attaching an overhead shower head, connect it to the top arm of the riser pipe. Ensure a proper seal with a washer.
- Install Hand Shower (if applicable): Attach your hand shower hose to the diverter/switch mechanism. Place the hand shower into the adjustable holder.
- Test for Leaks: Slowly turn on the main water supply and check all connections for leaks. Tighten any leaking connections carefully.

5. Operation
5.1 Height Adjustment
The Cornat TECBW3411 Vario Riser Pipe features an adjustable length, allowing you to set the overall height of your shower system between 80 cm and 130 cm. This adjustment is typically made by loosening a locking mechanism on the main vertical pipe, sliding the upper section to the desired height, and then re-tightening the mechanism. Refer to Figure 2 for the adjustable range.
5.2 Hand Shower Holder
The hand shower holder is equipped with a push-button slider. Press the button to release the holder, slide it up or down the riser pipe to your preferred height, and then release the button to lock it in place. The holder can also be angled for optimal spray direction.
5.3 Diverter/Switch
A practical switch (diverter) is integrated into the system, allowing you to easily switch the water flow between the overhead shower and the hand shower. Rotate or push the switch to select your desired water outlet.
6. Maintenance
To ensure the longevity and appearance of your Cornat TECBW3411 Vario Riser Pipe, follow these maintenance guidelines:
- Cleaning: Clean the chrome-plated surfaces regularly with a soft cloth and mild soap or a non-abrasive bathroom cleaner. Rinse thoroughly with water and dry with a soft cloth to prevent water spots.
- Avoid Harsh Chemicals: Do not use abrasive sponges, scouring pads, or cleaners containing ammonia, bleach, or acids, as these can damage the chrome finish.
- Check Connections: Periodically check all connections for any signs of leaks or corrosion. Tighten if necessary.
7. Troubleshooting
