Step-by-Step Guide to Using a Manual ProPress Tool
Using a manual ProPress tool involves preparing the pipe and fittings, marking insertion depth, and performing the pressing operation by securely crimping the fitting onto the pipe with the tool’s jaws until fully engaged, ensuring a leak-proof connection.
Preparing the Pipe and Fittings
Proper preparation is crucial for a successful and leak-free ProPress connection. Begin by cutting the copper pipe squarely using a displacement-type cutter. Ensure the cut is at least 4 inches away from where the vise will contact the pipe to prevent any potential damage. After cutting, meticulously remove any burrs from both the inside and outside of the pipe using a deburring tool or fine-grit sandpaper. This step is vital as burrs can interfere with the sealing element and the proper seating of the fitting.
Next, verify the sealing element, typically EPDM, is correctly fitted within the ProPress fitting. If a different sealing element is required for a specific application, carefully remove the factory-installed one and replace it accordingly. Consult the Viega ProPress Insertion Depth Chart to accurately mark the correct insertion depth on the pipe. This depth marking ensures the pipe is fully inserted into the fitting, creating a proper seal. The mark should remain visible after the assembly is complete for easy verification.
Before assembly, confirm that the copper tube is free of any surface imperfections, including metal stamped print lines, as these can compromise the seal. Finally, slide the fitting onto the prepared pipe, twisting slightly until it reaches the marked depth, ensuring the end of the tube makes contact with the stop inside the fitting. This meticulous preparation guarantees a reliable and secure ProPress connection.
Performing the Pressing Operation
Once the pipe and fitting are properly prepared, the pressing operation can commence. Begin by inserting the appropriate Viega ProPress jaw into the manual press tool, ensuring it is securely locked in place. Open the jaw and position it at a right angle onto the fitting, carefully aligning it with the fitting bead. Before initiating the press, visually re-check the insertion depth mark on the tubing to confirm that the fitting is fully seated.
With the jaw correctly positioned, firmly close the handles of the manual ProPress tool, applying consistent pressure until the pressing jaws fully engage the fitting. Maintain a firm grip throughout the pressing process, ensuring the tool doesn’t slip or move. Once the press is complete, the jaws will automatically release, indicating a successful crimp.
After pressing, open the jaw and carefully remove the press tool from the completed connection. Visually inspect the pressed connection to ensure the fitting has been uniformly crimped around the pipe. The presence of a consistent, even crimp signifies a secure and reliable joint. For larger diameter ProPress connections (2 to 4 inches), ensure that compatible rings are used with the appropriate actuators, avoiding any mixing of components from different manufacturers to prevent improper connections.
