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 in the chamber to prevent the dried material from being sucked in and damaging the vacuum pump (or solenoid valve).

 

2. Vacuum dryers cannot operate the vacuum pump for extended periods. Once the vacuum level meets the requirements for drying the items, first close the vacuum valve, then turn off the vacuum pump power. When the vacuum level falls below the required level, reopen the vacuum valve and power pump to continue vacuuming. This will extend the lifespan of the vacuum pump.

3. After repeated use, vacuum dryers may experience a loss of 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. To resolve this, replace the door seal or adjust the door latch extension interval. When the vacuum chamber drying temperature exceeds 200℃, slow leakage may occur. In this case, remove the back cover of the chamber and loosen the heater base with an Allen wrench, then replace the sealing ring or tighten the heater base. 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 regularly. Never wipe the glass door with reactive chemical solutions; use a soft cotton cloth. If the vacuum dryer is not used for a long time, clean the exposed electroplated parts, apply neutral grease to prevent corrosion, cover with a plastic film dust cover, and store in a dry indoor environment to prevent electrical components from getting damp and affecting operation.
