High-temperature ovens are widely used in biochemical, chemical and pharmaceutical, medical and health, agricultural scientific research, environmental protection and other research and application fields, as powder drying, baking and disinfection and sterilization of various glass containers. It is especially suitable for quick and efficient drying of dry heat-sensitive, easily decomposed, easily oxidized substances and complex components.

Pay attention to the following points when using:

1. The vacuum box casing must be effectively grounded to ensure safe use.

2. The vacuum box should be used in an environment where the relative humidity is less than or equal to 85% RH, and there are no corrosive gases, strong vibration sources, and strong electromagnetic fields.

3. There is no explosion-proof, anti-corrosion and other treatments in the vacuum chamber studio, and it is not allowed to dry items that are easy, explosive and prone to corrosive gases.

4. The vacuum pump cannot work for a long period of time, so when the vacuum degree reaches the requirements of dry goods, the vacuum valve should be closed first, and then the power of the vacuum pump should be turned off. This can extend the service life of the vacuum pump.

5. If the dry items are wet, it is better to add a filter between the vacuum box and the vacuum pump to prevent moisture from entering the vacuum pump and causing the vacuum pump to malfunction.

6. If the dried items are changed to light weight and small volume (small particles) after drying, they should be added with a barrier mesh in the vacuum port of the working room to prevent the dry matter from being sucked and damaging the vacuum pump (or solenoid valve).

7. After repeated use of the vacuum box, the phenomenon that it cannot be evacuated will occur. At this time, the door seal should be replaced or the extension distance of the door buckle on the box should be adjusted to solve. When the drying temperature of the vacuum box is higher than 200 ℃, slow air leakage will occur (except 6050, 6050B, 6051, 6053). At this time, the cover of the back of the box is disassembled and the base of the heater is loosened with an Allen wrench to replace the seal Loop or tighten the heater base to solve.

8. If the rubber plug of the bleed valve is difficult to rotate, it can be lubricated with an appropriate amount of grease. (Such as vaseline)

9. Except for maintenance, the left side box cover (except 6090 and 6210) cannot be disassembled to avoid damage to the electrical control system.

10. The vacuum box should always be kept clean. Do not wipe the door glass with a reactive chemical solution, use a soft cotton cloth.

11. If the vacuum box is not used for a long time, wipe the exposed electroplated parts with neutral grease to prevent corrosion, and put on a plastic film dust cover and place it in a dry room to prevent electrical components from being damaged by moisture. use.

12. Abnormal imagination occurs during use, please cut off the power and contact our company in time!
