Attention
1、To ensure safety, please connect ground when you use.
2、Do not use no oil inside the container.
3、When not in use, switch off the power supply to avoid accidents.
4、Use must be refueled in the pot, plug in the power, digital temperature table shows the actual measured temperature, knob switch, while observing the readings to the desired temperature setting, When the oil temperature exceeds the set temperature, the heat indicator light, that heater has begun to work, When the oil temperature to reach your desired temperature, the temperature indicator light, heat light goes out. Should be noted that the oil pan heating pipe can not be exposed oil surface, it would burn heating pipes, causing leakage phenomenon.
