1. If the vacuum dryer is not used for a long time, wipe the exposed electroplated parts and apply 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. Affect.
2. If the dry items are wet, it is better to add a filter between the vacuum box and the vacuum pump to prevent the wet gas from entering the vacuum pump and causing the vacuum pump to malfunction.
3. The vacuum dryer should be kept clean frequently. Do not wipe the glass of the door with a reactive chemical solution, and should be wiped with a soft cotton cloth.
4. The outer shell of the vacuum box must be grounded effectively to ensure safe use.
5. Except for maintenance, the left side box cover cannot be removed to avoid damage to the electrical control system.
6. If the rubber stopper of the air release valve is difficult to rotate, it can be lubricated with a proper amount of grease inside.
7. If the dry items are changed into light weight and small size (small particles) after drying, the vacuum port in the working chamber should be added with a barrier net to prevent the dry matter from sucking and damaging the vacuum pump (or solenoid valve).
8. The vacuum dryer is used in an environment where the relative humidity is less than or equal to 85 percent RH, and there is no corrosive gas, no strong vibration source and strong electromagnetic field.
9. There is no explosion-proof, anti-corrosion and other treatments in the vacuum dryer working room, and no items that are flammable, explosive, or prone to corrosive gas are allowed to be dried.
10. After the vacuum dryer has been used for many times, it will not be able to draw a vacuum. At this time, the door seal should be replaced or the door buckle on the box body should be adjusted to solve the problem. Carefully, when the drying temperature of the empty box is higher than 200℃, slow air leakage will occur. At this time, remove the back cover of the box and use an Allen wrench to loosen the heater base, change the sealing ring or tighten the heater base to solve the problem.
11. The vacuum pump cannot work for a long period of time. Therefore, when the emptiness meets the requirements of dry objects, the vacuum valve should be closed first, and then the power supply of the vacuum pump. This can extend the service life of the vacuum pump.
