3. Installation Instructions

Proper installation is critical for the performance of the Viega ProPress system. Always refer to the comprehensive Viega ProPress installation guide for detailed instructions and safety precautions. The following steps provide a general overview:

1. Pipe Preparation: Ensure the copper pipe ends are clean, free of burrs, and cut squarely. Deburr the inside and outside edges of the pipe.
2. Marking Insertion Depth: Use a Viega depth gauge to mark the correct insertion depth on the pipe. This ensures the pipe is fully seated within the fitting.
3. Insert Pipe: Fully insert the prepared copper pipe into the ProPress fitting until it reaches the marked depth.
4. Position Press Tool: Place the jaws of the Viega ProPress tool squarely over the fitting. Ensure the jaws are properly aligned with the fitting's bead.
5. Activate Press Tool: Activate the press tool to complete the connection. The tool will cycle automatically, creating a permanent, watertight seal.
6. Verify Connection: After pressing, visually inspect the connection to ensure the fitting has been properly pressed. The Smart Connect feature will assist in identifying any unpressed connections during system testing.

Important Safety Note: Always use appropriate personal protective equipment (PPE) and follow all local plumbing codes and safety regulations during installation. Only use Viega-approved pressing tools and jaws.

4. Operating Principles

The Viega 20633 ProPress 90-Degree Elbow is a passive component within a plumbing system. Once correctly installed, it functions to redirect the flow of fluid at a 90-degree angle. There are no user-operable parts or controls on the elbow itself. Its operation is integral to the overall plumbing system's design and function.

5. Maintenance

Once installed, the Viega ProPress fitting is designed to be maintenance-free. The robust copper construction and secure press connection ensure long-term reliability. Regular maintenance should focus on the overall plumbing system, including periodic checks for leaks or signs of wear on other components. No specific maintenance is required for the elbow itself.

6. Troubleshooting

The Viega ProPress system is highly reliable when installed correctly. Most issues arise from improper installation.

• Leakage During System Test: If a leak occurs during system pressure testing, the Viega Smart Connect feature is designed to identify unpressed connections. The presence of a leak at a ProPress joint indicates that the connection was not properly pressed.
• Resolution: If an unpressed connection is identified, re-press the fitting using the appropriate Viega ProPress tool and jaws. Ensure the pipe is fully inserted and the tool is correctly positioned. If the leak persists after re-pressing, the fitting may need to be replaced and re-installed.

For any persistent issues or concerns, contact Viega technical support.
