　　注意：打开您的热水器的电源开关后，开关指示灯就会亮起来，表示加热棒处于加热状态。当水温达到设定的温度时，温控器将自动关闭加热棒电源，因此开关灯也随之关闭。
　　NOTE: After the power switch to your water heater is turned "on", an indicator light in the "on/off" switch will glow to signal that the element is heating. The thermostat will automatically shut off the heating element when the selected operating temperature is reached, thus the light will turn off as well.

　　热水器正常运行期间，可能听到声音或噪音。这种噪音是正常的，可能是由于以下原因造成：
　　During the normal operation of the water heater, sounds or noises may be heard. These noises are common and may result from the following:

1. 在加热或冷却期间，金属配件的正常膨胀和收缩。
   Normal expansion and contraction of metal parts during periods of heat-up and cool-down.
2. 内胆底部累积的沉淀物会产生变化不定的噪音，并可能造成内胆过早老化。按照“排水和冲洗”地说明排泄并冲刷内胆。
   Sediment buildup in the tank bottom will create varying amounts of noise and may cause premature tank failure. Drain and flush the tank as directed under “Draining and Flushing”.

　　每台热水器都配置至少一根阳极棒，在保护玻璃内衬的内胆免受腐蚀，并延长热水器的寿命过程中，阳极棒也在缓慢的消耗。在某些水环境下，阳极棒和水会发生反应。一旦阳极棒消耗完，热水器将开始被腐蚀，并最终发展成泄漏。
　　Each water heater contains at least one anode rod, which will slowly deplete while protecting the glass-lined tank from corrosion and prolonging the life of the water heater. Certain water conditions will cause a reaction between this rod and the water. Once the anode is depleted, the tank will start to corrode, eventually developing a leak.

　　最常见的抱怨与阳极棒有关，因为如果水内存在溶解的氢化硫气体，将于阳极棒发生反应产生“臭鸡蛋”般的异味。这种供水系统需要安装从水质改善公司获得特制的过滤设备，才能成功消除所有的水异味问题。不要把阳极棒拆下并长期不用，否则将造成任何明示或默示的质量保证条款实效。
　　The most common complaint associated with the anode rod is one of a “rotten egg smell” produced from the presence of hydrogen sulfide gas dissolved in the water. The water supply system may require special filtration equipment from a water conditioning company to successfully eliminate all water odor problems.Do not remove this rod permanently as it will void any warranties, stated or implied.

　　由于人工软化水采用钠离子取代镁离子和钙离子，因此具有极强的腐蚀作用。使用软化水可能缩短热水器内胆的使用寿命。
　　Artificially softened water is exceedingly corrosive because the process substitutes sodium ions for magnesium and calcium ions. The use of a water softener may decrease the life of the water heater tank.

　　每隔3年时间，就要把阳极棒从热水器内胆上拆卸下来进行检查。如果阳极棒消耗超过50%，就应该更换阳极棒。
　　The anode rod should be removed from the water heater tank every 3 years for inspection. If the rod is more than 50% depleted, the anode rod should be replaced.
