1. The instrument should have a good grounding.

2. When used again, white smoke and odor will be emitted from the sleeve, and the color will change from white to brown and then back to white, which is a normal phenomenon. Due to the presence of oil and other compounds in the production process of fiberglass, it should be placed in a ventilated place and can be used normally after a few minutes of disappearance.

When using an electric heating sleeve with a capacity of over 3.3000ml, there may be a creaking sound due to differences in the furnace wire structure and related to the controllable silicon voltage pulse signal. You can use it with confidence.

When liquid overflows into the sleeve, please quickly turn off the power, place the electric heating sleeve in a ventilated place, and wait for it to dry before use to avoid the danger of electric leakage or electrical short circuit.

When not in use, please store the electric heating sleeve in a dry and non corrosive gas place.

6. Please do not use empty heating or dry burning.

When the environmental humidity is relatively high, there may be induced electricity transmitted through the insulation layer to the shell. Please ground the wire and pay attention to ventilation.
