1. The power supply wiring must meet the rated voltage and power requirements of the electric furnace, and the grounding protection must be good.
2. Before use, carefully check whether there are foreign objects inside the electric furnace, whether the power connection is normal, whether the operation panel is locked, etc., to ensure that there is no abnormality before starting.
3. Before use, you should pay attention to the preheating time and preheating temperature, under normal circumstances, you need to preheat for more than 30 minutes, and then operate after reaching the preset temperature.
4. During use, it should be operated in strict accordance with the operation guidelines and safety warnings, such as not being able to put your hand into the tube electric furnace for operation, not using metal tools to move at will, and not being able to conduct pressure tests at high temperatures.
5. Clean the inside of the electric furnace regularly to clean up the accumulated dust and stains to ensure that the inside of the electric furnace is clean and hygienic, and at the same time, it can also prolong the life of the electric furnace.
6. After use, turn off the power supply in time to avoid the electric furnace from being in a high temperature state for a long time.
7. The tube electric furnace should not use the power supply that exceeds the rated power and rated voltage to avoid overload.
8. Pay attention to the safety of the electric furnace, regularly check the voltage resistance of the electric furnace, such as cable insulation, insulating strips, plugs and sockets, whether there is any fragmentation and fracture, whether there are sparks splashing, heating, discoloration and other phenomena, and replace or repair them in time if necessary.
9. Maintain the electric furnace regularly, and pay attention to the inspection and maintenance of machinery, electrical appliances and other components to ensure its normal operation.
