InsituMain UVA[7] [8] [9] [G] >= 6" CLD 23 MLTPL

[5] Evaluted for Immediate Return to Service. Method #1 Using potable water as the source
    for cure water, the temperature of the cure water is raised from ambient temperature
    until the water reaches 180°F (82°C) and is held for 5 hours. The water is then allowed
    to cool down to below 100°F over a period of at least 1 hour. An additional ambient cure
    of 2 days is required prior to placing into service.
    Method #2 Using potable water as the source for steam, steam at a minimum temperature of
    200°F is used to cure and is held for 2 hours. The tube/liner is then allowed to cool
    down to below 110°F over a period of at least 30 minutes. An additional ambient cure of
    2 days is required prior to placing into service.
[6] Also Certified for the equivalent metric sizes, >= 150 mm.
[7] Evaluated for Immediate Return to Service.
[8] Certified for equivialent metric sizes.
[9] Product is cured when internal temperature reaches 160°F.
[G] Product is Certified to NSF/ANSI 372 and conforms with the lead content requirements for
    “lead free” plumbing as defined by California, Vermont, Maryland, and Louisiana state
    laws and the U.S. Safe Drinking Water Act.
