Installing Viega PureFlow Fittings

IM-PF 724596 1021 PureFlow Water System (EN)
Half-inch, snap-in bend supports are also available with a metal mounting
bracket (sold separately) for quick and easy stub outs with ½" Viega
PureFlow PEX tubing.
Seven stub out locations and numerous nail holes make this a versatile
option for stubbing out any number of lines or supporting tubing near
manifolds.
13.2 Copper Connections
Fittings are available to adapt Viega PureFlow PEX tubing to both copper
tubing and copper ttings. Copper tubing adapters slip over copper
tubing to provide a sweat connection. Always make the sweat connection
to the tting before connecting PEX to avoid heat damage to the tubing.
Copper tting adapters t into copper ttings to mate PEX to standard
sweat or ProPress ttings. As with copper tubing adapters, always make
sweat connections prior to PEX connection to avoid tubing damage.
CAUTION!
PureFlow Crimp tting adapters are not for use with the
Viega ProPress connection.

13.2.1.1 Prepping and Cleaning
Zero lead alloys are harder than standard alloys. Cleaning and prepping
the zero lead solder joint area with an abrasive product like emery cloth,
sandpaper or wire brush is an important step in the solder process.
Do not rely on ux alone. This surface preparation removes the natural
oxidative barrier that tends to form on zero lead alloys. Once this is done,
uxing and soldering should be done immediately to ensure the oxide lm
does not reform on the freshly cleaned surface.
13.2.1 Soldering Zero Lead Alloy PureFlow Fittings
Viega’s zero lead PureFlow ttings are manufactured from alloys known for
their low lead content and corrosion-resistant properties. These alloys have
lower thermal conductivity compared to standard (leaded) alloys, which
tends to make them more sensitive to soldering conditions. It is important
to follow the steps below to ensure consistent leak-free solder connections.
