1.The heating mantle should have a good grounding.
2.The first time you when you use it comprising a white smoke and smell smoke ,
color from white to brown and then white is a normal phenomenon ,
because oil and other compounds containing glass fibers in the production process, should be placed on ventilation place, can be used normally after a few minutes .
3. There are squeak when the capacity is more than 3000ml electric sets used- squeak sound is different furnace wire structure and thyristor surge pulse signal
related to ease of use.
4. When the liquid spilled into the jacket , please turn off the power immediately
and place the heating mantle in ventilated place , to be dried before use ,
to avoid the risk of leakage or electrical short circuit occurs .
5. when unused for long time please place the heating mantle in a dry place to save
corrosive gases .
6. Do not set heating or air dry .
7. When the humidity is too large relatively, the induction may be transmitted through the insulation layer be sure to connect the ground wire and pay attention to ventilation.
