Zurn PEX Tubing Installation Precautions
When working with Zurn PEX tubing we recommend following the
practices listed below to maximize the life of the system.
Note:
The Zurn PEX recommendation is intended to provide customers
with knowledge for the safe handling, storage, and installation of Zurn
PEX tubing. While this list is not comprehensive, an understanding of the
strengths and limitations of Zurn PEX tubing will help to ensure that it
maintains optimum performance char ac teristics throughout the life of the
system.
• Zurn PEX tubing should not be exposed to or stored in direct ultraviolet
light. When possible, protect the tubing with an opaque covering.
• Zurn PEX should not be exposed to direct flame. If it is necessary to
braze, solder, or weld, do so prior to connecting Zurn PEX to metal
pipe.
• Zurn PEX should never be used for electrical grounding. Consult the
NEC for recommended grounding methods when PEX is used.
• Zurn PEX should not be installed in conditions near extreme heat.
• Painting Zurn PEX is unnecessary. Water-based latex or acrylic paints
will not affect Zurn PEX tubing; however, oil-based paints or lacquers
should never be applied to Zurn PEX tubing.
• Zurn PEX should only be used in operating conditions that are
consistent with pressure ratings that appear on the tubing and
applicable standards.
• Zurn PEX tubing should not be subjected to prolonged exposure to free
chlorine concentrations greater than 4 ppm.
• Zurn PEX tubing that has been crushed or scratched should be
removed from the system and replaced.
• Zurn PEX should never come into contact with any chemicals, pipe
thread compounds, putty, mineral or linseed oil products.
• 5 degree F minimum installation temp
* Zurn PEX tube 2” and smaller meets the 25/50 flame spread index/smoke density index requirements specified in building codes for use in plenums when
encased with an appropriately listed ½” thick fiberglass insulation. Un-insulated installations using special accessories may also comply, please consult with the
factory for details.
** Only components and systems sold by Zurn PEX are covered by the Zurn PEX warranty.
***Only on coils.
NOTE: Please refer to page 31 adn 32 for ASTM standard descriptions.
