美国加州提议65警告
CALIFORNIA PROPOSITION 65 WARNING

  警告:美国加州已知这种产品包含可能导致癌症和生育障碍或其它有害生育的化学物质。(美国加州法律要求在美国加州境内将此类产品提供给用户时要提出警告。)
  WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. (California law requires this warning to be given to customers in the State of California.)

 
  重要:咨询主管部门,了解当地安装要求。
  IMPORTANT: Inquire with governing authorities for local installation requirements.

  注意:适用于澳大利亚和新西兰:管路过滤器应该安装在上游关闭阀和防回流阀进口之间。
  NOTE: For Australia and New Zealand: Pipeline strainers should be installed between the upstream shutoff valve and the inlet of the backflow preventer.
  重要的是,这个总成应该按照当地有关规定进行定期检测,至少每年检测一次以上,以确保使用条件得到保障。如果安装在防火喷淋系统上,所有机械式止回阀,如警告止回阀和防回流阀,都应该根据美国国家消防协会NFPA 13和NFPA 25标准进行流量测试和内部检查。
  Its important that this assembly be tested periodically in compliance with local codes, but at least once per year or more as service conditions warrant. If installed on a fire sprinkler system, all mechanical checks, such as alarm checks and backflow preventers, should be flow tested and inspected internally in accordance with NFPA 13 and NFPA 25.

In the event of such defects within the warranty period, the Company will, at its option, replace or recondition the product without charge.

  美国一些州不允许限制暗示保证的持续时间,一些州不允许排除或限制所伴随的损害。因此上述保证可能不适用于这些州。这个有限保证授予用户特别的法律权利,用户也可以拥有各州不同的其他权利。用户应该咨询所在州的法律,了解自身的权利。
  Some States do not allow limitations on how long an implied warranty lasts, and some States do not allow the exclusion or limitation of incidental or consequential damages. Therefore the above limitations may not apply to you. This Limited Warranty gives you specific legal rights, and you may have other rights that vary from State to State. You should consult applicable state laws to determine your rights.
