4. Pay attention to the width of the thermometer. When the temperature of the thermometer is about to reach the required temperature, adjust the automatic temperature control knob to make the green indicator light just shine, and then observe the thermometer and indicator light after ten minutes, if the temperature indicated on the thermometer is too needed, and the red indicator light is still on, the automatic temperature control knob will be slightly rotated in the counterclockwise direction.

Adjust until the temperature is constant at the required temperature and the indicator light turns red and green. The autothermostat knob is located on the top left of the front of the cabinet. Its scale plate cannot be used as a standard indication of temperature, only as a marker for adjustment.

5. In the process of constant temperature, if there is no need for three sets of heating wires to heat up at the same time, only one set of heating wires can be turned on. The higher the number of open groups, the faster the temperature rises.

6. After working hours, the air release regulator at the top can be turned on to discharge the moisture, and the blower can also be turned on.

7. After use, turn off all the heating wire group switches, and turn the knob of the automatic thermostat to the zero position in the counterclockwise direction.

8. Unplug the power plug.
