6. After the vacuum is pumped, close the vacuum valve first. If the vacuum valve is not closed tightly, please replace it, and then close or remove the power supply of the vacuum pump. (Prevent backsuction)
7. The drying cycle of the materials in the company shall be handled by observing the changes in the calendar, temperature meter and box body at regular intervals. If the pressure gauge index drops, there may be leakage and the pumping operation may be resumed.
8. After drying, open the air release valve to release the gas inside, then open the drying door to take out the material.
What are the safety precautions for vacuum oven?
1. The equipment belongs to high-power and high-temperature equipment, so safety should be paid attention to when it is used to prevent fire, electric shock and scald and other accidents.
2. The equipment should be placed in a dry and horizontal place in the room to prevent vibration. The power cord should not be placed next to metal objects or placed in a humid environment to avoid leakage caused by rubber aging.
3. It is strictly prohibited to stop or store inflammable, explosive and other low-fuel point, acidic corrosive and other volatile articles (such as organic solvent, compressed gas, oil basin, oil barrel, cotton yarn, cloth scraps, adhesive tape, plastic, paper and other inflammable articles) around the equipment.
4. Inflammable, explosive, acidic, volatile, corrosive and other articles are strictly prohibited from entering the container.
5. In the case that the user is not sure about the properties of baking materials, he/she must be confirmed by the R&D personnel before baking. Otherwise, it is strictly prohibited to bake by himself/herself. Paper, labels, plastic bottles, plastic cups and other common inflammables are not allowed to enter the box.
