Double door oven precautions

A double-door oven is constructed of angle steel, stainless steel plates, and cold-rolled steel plates. The insulation layer is filled with high-density aluminum silicate wool, which ensures the oven's heat retention and user safety.

Precautions for using a double-door oven:

1. The oven should be placed in a dry, level area indoors to prevent vibration and corrosion.

2. Pay attention to electrical safety. Install a power switch of sufficient capacity based on the oven's power consumption. Select sufficient power cables and ensure a good grounding connection.

3. For ovens equipped with an electric contact mercury thermometer thermostat, connect the two leads of the electric contact thermometer to the two terminal blocks on the oven top. Also, insert a standard mercury thermometer into the exhaust valve (the thermometer in the exhaust valve is used to calibrate the electric contact mercury thermometer and observe the actual temperature inside the oven). Open the exhaust valve hole. Adjust the electric contact mercury thermometer to the desired temperature and tighten the screws on the steel cap to achieve a constant temperature. However, be careful not to rotate the indicator iron beyond the scale when adjusting.

4. Only place the sample in the oven after all preparations are complete. Then connect and turn on the power. The red indicator light will illuminate, indicating that the oven is heating. When the controlled temperature is reached, the red light will turn off and the green light will illuminate, indicating that the constant temperature has been established. This operation must be monitored to prevent temperature control failure.

5. When placing the sample, be careful not to place it too close together. Do not place the sample on the heat sink to prevent it from blocking the upward flow of hot air. Do not bake flammable, explosive, volatile, or corrosive items.

6. When observing the sample in the workroom, you may open the outer door and observe through the glass door. However, it is best to open the door as little as possible to avoid affecting the constant temperature. Especially when operating above 200°C, opening the door may cause the glass door to cool suddenly and crack.

7. For ovens with a blower fan, the blower must be on during the heating and constant temperature processes. Otherwise, the temperature uniformity in the workroom may be affected and the heating elements may be damaged.

8. After work is completed, promptly disconnect the power supply to ensure safety.

9. Keep the inside and outside of the oven clean.

10. During operation, do not exceed the oven's maximum operating temperature.

11. To prevent burns, use specialized tools when removing and placing test samples.
