■ The minimum clearance requirement when pressing connections near
an existing brazed connection is two tube diameters.
■ To ensure proper sealing of both the soldered and press connections,
a minimum distance when pressing connections near an existing
soldered 󶈵tting must be maintained.
Refer to the table below.
4.4 Soldering or Brazing
4.4.1 Using ProPress Near Existing Fittings
Check the 󶈵tting to make sure there is no residual solder
or other foreign debris on the tube that will be inserted into
the Viega ProPress 󶈵tting.
To prevent damage to the sealing element and ensure proper sealing
of the soldered/brazed joint and the press connection, maintain proper
soldering/brazing distances from the 󶈵tting:
■ When soldering near a ProPress connection: three tube diameters.
■ When brazing near a ProPress connection: nine tube diameters.
Refer to the following table.
