美国人家用电热水器 安装说明书和使用及维护指南(13)
关闭排水阀。打开最近的热水水龙头,让内胆完全注满水。为了清除管道内任何剩余的空气和沉淀物,请在稳定出水后,让热水水龙头持续出水3分钟。
Close the drain valve. Open the nearest hot water faucet and allow the tank to fill completely with water. To purge the lines of any excess air and sediment, keep the hot water faucet open for 3 minutes after a constant flow of water is obtained.
检查加热元件周围是否有泄漏。
Check for leaks around the element(s).
连接加热元件上的电线。确保所有连接的电线牢固可靠。重新安装温控器塑料盖,确保固定点稳固连接在温控器上。
Connect the electric wires to the heater element. Make sure all wires are secure.Replace the plastic thermostat cover making sure the attachment points are engaged on the thermostat.
重新安装绝缘保温层和观察门。
Replace the insulation and access door(s).
确保热水器已经注满水。如果加热元件没有浸在水中就通上电流,将会造成加热元件的损坏。
Make certain the tank is filled with water. Applying electric current to heater elements not submerged in water will destroy them.
重新接通热水器的电源。
Restore the electric power supply to the water heater.
