Key points to note when using a vacuum dryer

1. Vacuum dryers without explosion-proof or corrosion-proof chambers must not be used to dry flammable, explosive, or corrosive substances. If the items being dried are moist, a filter should be placed between the vacuum chamber and the vacuum pump to prevent moisture from entering the pump and causing malfunction. If the dried items are lightweight and small (small particles), a screen should be placed at the vacuum port inside the chamber to prevent the dried material from being sucked in and damaging the vacuum pump (or solenoid valve).

 

2. The vacuum pump of the Vacuum Dryer cannot work for a long time. Therefore, when the vacuum degree meets the requirements of the dried items, the vacuum valve should be closed first, and then the power supply of the vacuum pump should be turned off. When the vacuum degree is lower than the requirements of the dried items, the vacuum valve and the power supply of the vacuum pump should be turned on again to continue evacuating the vacuum. This can extend the service life of the vacuum pump.

3. After repeated use, the vacuum dryer may experience a failure to create a vacuum. In this case, except for maintenance, do not disassemble the left side cover of the vacuum dryer to avoid damaging the electrical control system. Replace the door seal or adjust the door latch extension interval to resolve the issue. When the vacuum chamber drying temperature exceeds 200℃, slow air leakage may occur. In this case, remove the back cover of the chamber and loosen the heater base with an Allen wrench. Replace the sealing ring or tighten the heater base to resolve the problem. If the rubber stopper of the vent valve is difficult to rotate, apply a suitable amount of grease for lubrication.

 

4. The vacuum dryer should be kept clean at all times. Never wipe the glass door with reactive chemical solutions; use a soft cotton cloth instead. If the vacuum dryer is not used for an extended period, clean any exposed electroplated parts, apply a neutral grease to prevent corrosion, cover it with a plastic dust cover, and store it in a dry indoor environment to prevent moisture damage to electrical components and ensure proper operation.
