The drying oven has three temperature ranges: RT+ 10 ~ 250℃, RT+ 10 ~ 300℃, 100 ~ 400℃ (high temperature drying oven). When the working temperature is lower than 150℃, the oven with the temperature range of RT+ 10 ~ 250℃ can be selected; When the frequently used temperature is between 150 ~ 290℃, it is suggested to choose an oven with the temperature range of RT+ 10 ~ 300℃.
When the frequently used temperature is between 260-290℃, it is suggested to equip the motor with overheating protection device and geothermal protection of the motor. When the working temperature is higher than 300℃, please choose a high-temperature oven with the temperature range of 100 ~ 400℃.
Application mode
1. Insert the thermometer into the base (in the middle of the ventilation regulator at the top of the box).
2. Insert the power plug into the power socket.
3. At the beginning of grouping, turn the heating wire to the position of 1 or 2 (depending on the required temperature), and then turn on the blower to promote hot air convection. At the beginning of grouping, when the heating wire is turned on, the red indicator lights up.
4. Pay attention to 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 ten minutes later. If the temperature displayed on the thermometer is too high and the red indicator light is still on, turn the automatic temperature control knob slightly counterclockwise.
Directly adjust the temperature to the required temperature, and the indicator light will display red and green in turn. The thermostat knob is on the top left in front of the box. Its scale plate can not be used as a standard indication of temperature, but only as a mark of adjustment.
5. In the process of constant temperature, if you don't need three groups of heating wires to heat at the same time, you can only turn on one group of heating wires. The more open groups there are, the faster the temperature rises.
6. After the working hours, you can open the deflation regulating valve at the top to discharge moisture, or you can turn on the blower.
7. After use, turn off all the electric heating wire grouping switches and turn the automatic thermostat knob counterclockwise to zero.
8. Unplug the power plug.
