The power supply voltage must match and be stable with the voltage required by the product


This instrument must be effectively grounded


During the first heating process, it is normal for there to be smoke and odor inside the electric heating plate, which is caused by the insulation material inside the electric heating plate at high temperatures. It will disappear after a few uses


It is normal for the surface of stainless steel material to have yellowing marks, which are caused by high-temperature debugging during factory production
