Precautions for use
1. Conduct an annual inspection of the electric heating cable before use in winter. Test insulation and waterproof inspection. Insulation test of electric heating and regional pipelines with ohmmeter 550V, 1000V gear, insulation resistance should be greater than 20M.
2. It is forbidden to expose the electric heating cable to the outside of the insulation layer, otherwise it will increase energy consumption and reduce the service life.
3, the first end of the electric heating cable is connected to the power cord, the first and the last end of the head should be waterproof AWG Silicone Rubber Cable.
4. When the ambient temperature is close to zero, the electric heating cable control switch is turned on to make the production temperature prevent the inlet and outlet pipes from freezing.
5, electric heating should be installed leakage protection switch, should work in the dry state.
