阳极棒/水的异味
Anode Rod/Water Odor
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。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 a “rotten egg smell” produced from the presence of hydrogen
sulfide gas dissolved in the water. Do not remove this rod permanently
as it will void any warranties, stated or implied.
如果水产生异味或变色，可以从配件清单中选择订购特制的阳极棒。这种阳极棒可能减轻但不能消除水异味问题。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。
The parts list includes a special anode that can
be ordered if water odor or discoloration occurs. This rod may reduce
but not eliminate water odor problems. The water supply system may
require special filtration equipment from a water conditioning company
to successfully eliminate all water odor problems.
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。（请参阅维护章节中的“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. (See “Replacing
the Anode Rod” in the maintenance section.) |

热水器声音
Water Heater Sounds
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:
- 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.
- 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“排水和冲刷”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”.
层积
Stacking
当从热水器内取出一系列少量热水（3加仑以下）时，会发生层积现象。这将增加加热元件的周期性工作频率，并可能导致热水出水口处水温升高。建议在热水供应管道上安装防烫装置，减少被烫伤的危险。
Stacking occurs when a series of short draws of
hot water (3 gallons or less) are taken from the water heater tank. This
causes increased cycling of the heater elements and can result in increased
water temperatures at the hot water outlet. An anti-scald device is recommended
in the hot water supply line to reduce the risk of scald injury.
