Installation
1. Viega's copper manifolds are copper (male) on the inlet and outlet of the header, which can be connected to
the primary loop (boiler loop) with ProPress or soldered connections. The length of the header is in accordance with
ProPress insertion depths and ProPress minimum clearance to existing solder connection. Copper manifolds should
be installed using isolation (ball valves) valves on the supply and return headers. End caps should also be used on at
least the return manifold for ease of pressurizing and purging.
2. Soldering Viega's copper manifolds should be done prior to the connection of ViegaPEX Barrier or FostaPEX.
Excessive heat can cause the PEX Press connections and outlet connections to leak.
3. When using ProPress the PEX Press connections can be made at any time during installation.
4. For more information on Viega's ProPress or PEX Press systems see the appropriate product instructions or contact
your Viega sales person.
Solder Installation
1. Cut copper tubing cleanly with tube cutter.
2. Ream and debur cut copper tubing.
3. Clean the inside of the copper end cap and copper tubing (tting brush / emery cloth). The copper should shine.
4. Brush an even layer of ux over the copper tubing and copper end cap.
5. Push the joint together until the copper tube seats full depth. Wipe off excess ux.
6. Heat the joint with a torch, moving the ame back and forth to heat evenly. Hold the solder against the joint on
the side opposite the ame until it melts and ows into the joint. Touch the solder 360° around the tubing. The
joint should appear full on all sides. The solder hardens as it cools.
7. Avoid overfeeding the joint with solder. The amount of solder required is equivalent to the diameter of copper
tubing being soldered.
