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.
图３，4和5仅仅为120/240伏、2线型号提供参考接线图。为了正确进行电气连接，请随时注意参考位于热水器上的接线图。
Figures 3, 4, and 5 are provided as reference
drawings for the 120/240v 2-wire models only. Always reference the wiring
diagram located on the water heater for the correct electrical connections.
在将电线安装到热水器上时：
When installing the
electrical wiring to the water heater:
- 在进行任何电气连接之前，请确保热水器已经住满水。（参阅图2）
Be sure tank is completely filled with water before
making any electrical connections. (See Figure 2)
- 切断通往热水器的电源。
Shut off the power to the unit.
- 卸下热水器顶部接线盒盖上的固定螺丝。把盖子放在旁边。
Loosen the screw holding the junction box cover
to the top of the water heater. Set the cover aside.
- 遵守当地供电部门的要求和相关的规定将电源线连接到热水器上。作为标准配置，在接线盒上有一个1/2英寸的开口，用于导管连接。
Connect the electrical supply to the water heater
in accordance with local utility requirements and codes. A standard
1/2 inch opening has been made in the junction box for conduit connections.
- 通过将电气部件上的接地端子连接到热水器接线盒里绿色接地螺丝上，实现热水器的接地。
Ground the water heater by connecting a grounding
wire from the electrical service ground terminal to
the green grounding screw in the junction box of
the water heater.

注：将电源通到没有淹没在水里的加热元件上，将导致加热元件的损坏。对于这种原因导致的加热元件的损坏，制造商对此将不承担质量保证的责任。
Notice: Applying electrical power to elements
that are not submerged in water will destroy them. The manufacturer
will not warranty any elements damaged in this manner. |
