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。
　　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.

　　如果需要更换阳极棒，请先关闭热水器电源。确保供应到热水器的冷水已经关闭。打开热水水龙头，降低热水器内胆的压力。从热水器底部的排污阀排出大约5加仑的水。拆卸阳极棒。参照第15页的有关阳极棒的“更换配件图解”进行操作。
　　For replacing the anode, shut-off the power to the water heater. Be sure the cold water supply to the heater is turned off. Open the hot water faucet to depressurize the water tank. Drain out 5 gallons of water from the drain valve at the bottom of the heater. Remove the anode rod. See the "Repair Parts Illustration" for anode rod location on page 15.

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:

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.

爆炸危险 Explosion Hazard　　如果降温减压安全阀出现滴水或泄漏现象，需要请有资格认证的管道工来维修。 　　不要塞住阀门。 　　不要拆卸掉阀门。 　　 不遵守这些说明可能会导致死亡或爆炸。 　　If the temperature and pressure relief valve is dripping or leaking, have a licensed plumber repair it. 　　Do not plug valve. 　　Do not remove valve. 　　Failure to follow these instructions can result in death or explosion.

　　每年至少人工操作一次降温减压安全阀，以确保保持正常的工作状态。为了防止水的破坏，降温减压安全阀必须正确连接排泄管，并通过排泄管引导到适当的排污口。站立位置离出水口要有适当的距离（排泄物可能是热的），缓慢提升并释放降温减压安全阀上的杠杆手柄，使得阀门工作自如，然后重新回到关闭位置。如果阀门无法完全重置并继续释放出水来，请立即关闭电源和冷水进水阀，致电拥有资格认证的维修技术人员来维修。
　　Manually operate the temperature and pressure relief valve at least once a year to make sure it is working properly. To prevent water damage, the valve must be properly connected to a discharge line which terminates at an adequate drain. Standing clear of the outlet (discharged water may be hot), slowly lift and release the lever handle on the temperature and pressure relief valve to allow the valve to operate freely and return to its closed position. If the valve fails to completely reset and continues to release water, immediately shut off the electrical power and the cold water inlet valve and call a qualified service technician.
