1. The vacuum drying box must be ineffective grounded to ensure the use of insurance. 2. The vacuum box should be used in conditions with absolute humidity ≤ 85% RH, no erosive gas around, no violent sources of shock and strong electromagnetic fields. 3. The vacuum box task room is not solved by explosion-proof, anti-erosion, etc., and there is no need to put objects that are easy, flammable, and prone to aggressive gases to dry. 4. The vacuum pump does not have the task of long-term era. Therefore, when it is believed that the vacuum reaches the request of the dry object, the vacuum valve should be opened first, and then the vacuum pump power supply should be opened. When the vacuum is less than the request of the dry object, the vacuum valve and the vacuum pump power supply are turned over, and the vacuum pump is connected. Vacuum, which extends the life of the vacuum pump. 5. If the dry object is wet, it is better to exit the filter between the vacuum box and the vacuum pump to prevent the humid gas from entering the vacuum pump and forming a vacuum pump failure. 6. If the dry object is changed to light weight after drying, the volume is small and small granular. The vacuum chamber should be added in the task chamber to block the mesh to prevent the dry matter from inhaling and protect the vacuum pump or solenoid valve. 7. After repeated use of the vacuum box, there will be no scene that can be vacuumed. At this time, the door cover should be changed or the door buckle on the inside of the box should be extended. The letter believes that when the drying temperature of the vacuum box is higher than 200 °C, a slow-breathing phenomenon will occur. At this time, the front cover of the door is opened and the base of the heater is loosened with a hexagonal handle, and the washer is exchanged or the base of the heater is tightened. 8. If the paper is stuck in the cylinder, it can be coated with excessive grease and smooth. 9. Except for training, there is no way to disassemble the left inner cover to protect the electric material control system. 10. The vacuum box should be kept clean from time to time. Do not wipe the door glass with a reverberant chemical filtrate and wipe it with a solid cotton cloth. 11. If the vacuum drying oven is not necessary temporarily, wipe the silver-plated parts inside and wipe them with neutral grease to prevent erosion, and put on the plastic film dust cover and rest in the dry room to avoid the electric parts. Protected by frost and used in reaction. 12. In the application of the idea, please cut off the source and get in touch with our company in time!
