Protection: 		反虹吸倒流
Against back-siphonage backflow

安装要求
Installation Requirements:

  1. 如果配置有工厂安装的台面，则安装至少要高于地面25毫米，如果在管道设施现场安装，则高度至少要150毫米。
    Install a minimum of 1" above flood level of fixture if factory deck mounted or not less than 6" if general plumbing field application.
  2. 安装时要使阀盖侧面朝上，要便于测试和维修。不要安装在隐蔽的位置或区域，在这些地方，由于阀内件正常磨损产生的水泄漏可能导致阀门损坏。
    Install bonnet side up and allow for accessibility for testing/service. Do not install in concealed locations or areas where water leakage due to normal wear of the internal parts can cause damage.
  3. 根据需要确定供水管道和阀门通径。供水管道通径不要太小，阀门通径不要太大。
    Do not undersize supply or oversize the valve in relation to demand.
  4. 不要安装在可能产生反压力的地方。
    Do not install where back-pressure can occur.
  5. 防止冻结。
    注：左侧出口要增加"L"后缀。
    Protect from freezing.
    Note: Use "L" suffix for left-hand outlet.
  6. 建议在防回流阀前安装一个过滤器，防止止回阀受到污染和阀门在再增压期间出现泄漏或溢出。
    The installation of a strainer ahead of the backflow preventer is recommended to prevent fouling of the check assembly and resultant spillage from the valve during repressurizing.

　　按照当地主管机关的要求进行定期检测。每个五年更换阀内件。
