Selection of instructions:

The 1 element allows for work under the following conditions

Air relative humidity is no more than 95%, no explosive and corrosive gas.

Working voltage should be greater than the rated value to 1.1 times, the shell should be effectively grounded.

2 when heating liquid, the effective heating zone must be all the intrusion of the liquid, the air burning is strictly prohibited. Found the tube surface scaling or carbon, should be cleaned and then, so as not to affect the heat and life.

3. Heating the fusible metal or solid Xiaoyan. Alkali. Asphalt. Paraffin should be to reduce the use of voltage. Medium melting, can rise to the rated voltage.

4 heating nitrate should be considered when safety measures to prevent explosion accidents.

5 when the air element should be evenly arranged, so that the components have good cooling conditions, so that the flow of air full heating.

6. Part of the wiring should be placed in the insulating layer outside, avoid and corrosive, explosive medium. Water contact; wiring should be able to bear long-term connection portion of the temperature and heating load, the wiring screws fastening should avoid overexertion.

7 components should be placed in the dry place, if the insulation resistance is less than 1M, when the insulation can be 200 degrees Celsius oven drying, or reducing the voltage by electric heating, until the insulation resistance.

8 all kinds of tubular electric heating element of the highest temperature use: see table below:
