Page 8: Aquasafe Exposed Listing
Uponor AquaPEX piping carries a standard grade rating recommended by the Plastics Pipe Institute (PPI). Uponor AquaPEX piping is listed to NSF International Standard 14, which defines requirements for ingredients, materials, products, quality assurance, and marking. Uponor AquaPEX piping and Uponor sprinkler adapters are listed to NSF International Standard 61, which defines requirements for health effects. -

• Uponor AquaPEX piping shall not be installed in locations with direct exposure to sunlight. • Piping shall be supported every 24" with metal pipe hangers designed for use with non-metallic pipe/piping. Follow minimum bend radius limitations as detailed on page 26 of this installation guide. -
Page 10: Handling And Storing Uponor Aquapex Piping And Components
• Do not store sprinkler assemblies or cover plates in areas that may exceed 100°F (37.8°C). • Uponor PEX piping is listed for fire protection systems that do not exceed 130 psi (8.9 bar) 120°F (48.9°C). • Do not use PEX piping where temperatures and pressures exceed ratings. -
Page 11: Uponor Aquasafe Multipurpose Fire Sprinkler System Overview
(as applicable). Uponor AquaSAFE multipurpose fire sprinkler system overview The AquaSAFE system is a cost-effective way to provide reliable and safe home fire protection. This progressive technology combines the plumbing and fire sprinkler systems into an efficient, cost-effective, multipurpose system featuring dependable Uponor AquaPEX piping. -
Page 12: Features And Benefits
In a multipurpose system, individually heat-activated fire sprinklers attach to Uponor sprinkler adapter fittings. Flexible Uponor AquaPEX piping supplies water to each sprinkler, as well as cold-water plumbing fixtures. Because the plumbing and the fire sprinkler systems are merged into one system, water availability to the sprinklers is verified each time a plumbing fixture is used. -
Page 13: Standalone Sprinkler System Overview
Standalone sprinkler system overview Uponor AquaSAFE products may also be installed as a standalone sprinkler system as allowed by NFPA 13D. Standalone fire sprinkler systems utilize the same individually heat- activated fire sprinklers as in multipurpose systems, but they are supplied by completely separate piping serving only the fire sprinklers. -
