U Shape Tubular Heating Element for Commercial Food Steamer

1. Components are allowed to work under the following conditions:

(1) The relative humidity of the air is not more than 95%;
(2) The working voltage is not more than 1.1 times the rated value, and the housing should be effectively grounded.

2. when the heating medium is liquid, the effective length of the component (H1 or H2) must be fully immersed in the liquid. The heating part of the component should have a certain distance from the container wall, generally more than 50-60mm.

3. Components that heat liquids shall not be used to heat gases or solids.

4. heating liquid components, such as scale or carbon on the surface of the pipe, should be removed after use, so as not to affect the service life of the components and reduce thermal efficiency.

5. melting light metal or salt, alkali, asphalt, paraffin, etc. for solid heating, should be reduced voltage start, until the solid heating medium all melted to rise to the rated voltage.

6. Safety measures should be considered when heating nitrate to prevent explosion accidents.

7. the component wiring part should be placed in the insulation layer, heating outside, and avoid contact with corrosive and explosive gases. Keep the outlet end dry and clean to avoid flashover or short circuit. Do not exert too much force when wiring.

8. the end of the component may overflow a small amount of paste, this is the sealing material, does not affect the use, after the power off, the overflow can be wiped clean.

9. the components should be stored in the air circulation, relative humidity is not greater than 85%, no corrosive gas room.

10. after the component is used for a period of time and is not used for a long time and is damp, when the cold insulation resistance is less than 1 trillion ohm, the component can be placed in a drying oven at a temperature of about 200 degrees, or reduce the voltage and direct electric heating, remove the moisture, until it returns to normal.
