The installer should take precautions to keep the Viega ProPress Stainless
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.
Installers should follow the precautions listed above to keep the Viega
ProPress Stainless connection cool.
