重要提示：您的热水器只能采用崭新的降温减压安全阀。不要采用旧的或原有的阀门，否则可能会损坏或不符合新热水器的工作压力。不要在安全阀和热水器之间安装任何阀门。
　　Important: Only a new temperature and pressure relief valve should be used with your water heater. Do not use an old or existing valve as it may be damaged or not adequate for the working pressure of the new water heater. Do not place any valve between the relief valve and the tank.

• 必须与适当的排泄管道连接。
  Must be connected to an adequate discharge line.
• 不能接触任何电气部件。
  Must not be in contact with any electrical part.
• 额定压力不能高于热水器参数板上显示的工作压力。
  Must not be rated higher than the working pressure shown on the data plate of the water heater.

• 其终端离地面排水口或建筑物外部高度不能超过6英寸。
  Must terminate a maximum of 6 inches above a floor drain or external to the building.
• 必须能够承受121°C的高温而功能仍然正常。
  Must be capable of withstanding 250°F (121°C) without distortion.
• 必须安装到具有完全排泄能力的阀门和排泄管上。
  Must be installed to allow complete drainage of both the valve and discharge line.
• 不能小于安全阀的管道口径，也不能在排泄管上安装任何缩径管接头。
  Must not be smaller than the pipe size of the relief valve or have any reducing coupling installed in the discharge line.
• 在安全阀和排泄管之间不要加盖、闭塞、堵塞或包含任何阀门。
  Must not be capped, blocked, plugged, or contain any valve between the relief valve and the end of the discharge line.

　　如果本热水器被用作为太阳能贮存热水器，或作为太阳能系统的备用热水器，那么输入热水器的水温可能会超过49^oC。因此要在供水管道上安装调节阀（混水阀）或其他温度限制阀门，使得供水温度不会超过49^oC。
　　If this water heater is used as a solar storage heater or as a backup for the solar system, the water supply temperatures to the water heater tank may be in excess of 120°F. A tempering valve or other temperature limiting valve must be installed in the water supply line to limit the supply temperature to 120°F.

　　注：太阳能水加热系统产生的热水温度经常会超过82^oC，这将导致热水器发生故障。
　　Note: Solar water heating systems can often supply water with temperatures exceeding 180°F and may result in water heater malfunction.

	触电危险 维修之前要切断电源。 操作之前安装好全部部件和控制板。 否则可能导致伤亡或触电。 Electric Shock Hazard Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electric shock.

	火灾危险 要采用10级实心铜线。 要采用通过美国UL认证的应变消除装置。 将地线连接到绿色的底线螺丝上。 否则可能导致伤亡、火灾或触电。 Fire Hazard Use 10 gauge solid copper wire. Use a UL approved strain relief. Connect ground wire to green ground screw. Failure to do so can result in death, fire, or electrical shock.

　　如果您不具备正确安装本热水器电气线路的基本技能，请停止安装，而是请有资格认证的电工来从事安装工作。
　　If you lack the necessary skills required to properly install the electrical wiring to this water heater, do not proceed, but have a qualified electrician perform the installation.

　　在进行电气连接时，要确保
　　When making the electrical connections, always make sure:

• 电源供应具备适当的过载保险丝或断路器保护。
  The electrical supply has the proper overload fuse or circuit breaker protection.
• 电线大小和连接符合所有相关规定。
  Wire sizes and connections comply with all applicable codes.
• 电线包裹在经过认可的导管内（如果当地有关规定要求的话）。
  Wiring is enclosed in approved conduit (if required by local codes).
• 热水器和电源供应都有适当的接地。
  The water heater and electrical supply are properly grounded.

　　在下一页可以看到图6和接线图。为了正确进行电气连接，请随时注意参考接线图。在接线盒盖内也可以看到接线图。
　　Figure 6 and the wiring diagram can be found on the next page. Always reference the wiring diagram for the correct electrical connection. The wiring diagram can also be found on the inside of the junction box cover.

1. 切断通往热水器的电源。
   Shut off the power to the unit.
2. 在进行任何电气连接之前，确保热水器已经完全注满水。
   Be sure tank is completely filled with water before making any electrical connections.
3. 通过旋下3个螺丝来拆卸接线盒。把盖子放在旁边并察看内面的接线图。
   Remove junction box cover that is secured by 3 screws. Place the cover aside and view the wiring diagram on the inside.
4. 按照当地供电公司和有关规定的要求将电源连接到热水器上。在接线盒上有一个标准1/2英寸的开口，用于导管连接。只能采用经过认证的导管及铜线或Rpmex.
   Connect the electrical supply to the water heater in accordance with the local utility requirements and codes. A standard 1/2 inch opening has been made in the junction box for the conduit connections. Use approved conduit with copper wires only or Romex.
