1, the element allows work under the following conditions:
A. air relative humidity is not more than 95%, explosive and corrosive gas. (except explosion-proof heater)
B. working voltage should be not greater than 1.1 times that of rating shell should be effectively grounded.
C. insulation resistance 1 m or more Ω dielectric strength: 2 kv / 1 min.
2, electric heat pipe should be fixed positioning, effective heating area must be completely immersed in liquid or solid metal, it is forbidden to empty fire. Found a scale or carbon tube body surface, should be timely clean again, lest absence made the cooling and shorten service life.
3, heating fusible metal or solid nitrate, alkali, asphalt and paraffin etc, should be used to reduce voltage, after being medium melt, can rise to the rated voltage.
4, uniform heating air element should cross arranged, make the element has good heat dissipation conditions, make the air flow can be fully heated.
5, heating security measures should be considered when nitrate, preventing explosion accidents.
Part 6, connection should be on the outside of the insulation layer, avoid contact with corrosive, explosive medium, water; Lead connection should be able to long-term bear part of the temperature and heating load, the connection screw fastening should avoid too hard.
