重要：温控器的拆卸和更换涉及到电路连接的断开。下列步骤只能由通过认证的技术人员进行。如果没有按照这些步骤进行操作，可能导致触电造成人身伤亡事故。
IMPORTANT: Removal and replacement of the thermostat
involves the disconnection of electrical connections. The following
procedures must only be performed by a qualified service technician.
Failure to follow these instructions could result in electrical shock
causing death or injury.
按照下列说明更换温控器：
Follow the instructions
below to replace the thermostat:
- 拔掉热水器的头，关断水供应，拆卸前盖。
Unplug the heater, shut off the water supply and
remove the front cover.
- 断开电气连接端子（参阅图7，#2和5）。在两（2）个十字帽螺丝上断开电气连接端子（参阅图7，#3和4）。
Disconnect the electrical terminals (See Figure
7, # 2 & 5). Disconnect the electrical terminals from the two (2)
phillips head screws (See Figure 7, # 3 & 4).
- 拆卸两个安装螺丝（参阅图7，#8和9），然后拆卸温控器。
Remove the two mounting screws (See Figure 7,
# 8 & 9), then remove the thermostat.
- 用新的温控器进行更换，用两个安装螺丝加以紧固。确保新的温控器牢固地安装在容器表面。重新连接电气端子。
Replace with the new thermostat and secure with
the two mounting screws. Be sure the new thermostat is securely in place
against the tank surface. Reconnect the electrical terminals.
- 打开热水器的水供应，将容器注满水。
Turn on the water supply and fill the tank completely
with water.
- 重新安装前盖板。等到容器注满水后，将热水器插头插上。将开关拨到"ON"的位置打开电源，将温度刻度设置在所需要的温度。
