1, when heating liquids, efficient heaters need to be fully immersed in liquid, do not dry. When he found the scale or soot on the surface of the pipe should be cleared in a timely manner, so as not to affect the heat and shorten the service life.

2, heating solid nitrate, alkalinity, asphalt, paraffin, and so on, should reduce the use of voltage, medium melts, rising to its rated voltage.

3, the heat should consider safety measures for nitrate, explosion prevention.

4, the original heated air should be crossed even rehearsals, makes the symbol of good thermal conditions, make the flow of the air can be fully heated.

5 part, wiring insulation layer should be placed on the outside, avoid contact with corrosive or explosive media, water; lead wire should be part of the temperature under wiring and the heating load for a long time, Terminal screw fastening should be avoided when overexert.

6, heating elements should be stored in a dry place, if placing the insulation resistance drops below 1MQ, drying in the oven at about 200 degrees Celsius, or reduce the voltage by heating, until the resumption of insulation resistance.
