The installer should take precautions to keep the Viega ProPress
connection cool:
Wrap the connection with a cold wet rag.
Protect the connection with a weld blanket.
Prefabricate solder connections/welded 󶈵ttings prior to installing the
press 󶈵tting. (Ensure tube has cooled before installing the 󶈵tting).
Apply heat sink gel or spray or spot freezing
4.5 Welding
To prevent damage to the sealing element, maintain proper welding
distances from the 󶈵tting. If welding adjacent to the connection, weld a
minimum of four inches away.
