1 boiler and electric heating tube interface connection does not feed length must be in the electric heating tube is not the heating end length.
2 of the best and the boiler installation is the electric heating tube is vertically upwards towards the ground installation,interface. Horizontal installation can also be. Must not beinstalled vertically downward by, because it is possible tooverflow heat insulated terminal corrosion electric heatingtube.
3.注意区 分三角形连接和星形连接，我司提供电热管均有两种电压规格，一般而言，按标注 小的电压用三角形连接，大的电压用星形连接。
3 pay attention to the distinction between triangle connectionand star connection, our company provide electric heating tube has two kinds of voltage specification, in general,according to mark a small voltage with delta connection, highvoltage with star connection.
4 electric heating pipe shall be connected grounding system
5.使用正 确型号的接线片（适当的 直径和适合于电源线的规格），使用合 适的夹紧工具夹紧电线上的接线片。 6.电热管工作一定时间后（如一个采暖周期），建议在 重新使用之前拿出来做机械性的擦拭，用较软 的布拭去表面上之结垢，严禁用 化学性的清洗液清洗。
5 lugs on the right type of (diameter specifications andsuitable for power line properly), using the patch clampingtool clamping wire suitable. 6 electric heating tube after working for a certain time (such as a heating cycle), suggestto use before out to do cleaning machinery, use cloth wipethe surface fouling soft, prohibit the use of cleaning fluid cleaning chemical.
