Key points to note when installing a vacuum dryer

Key points to note during Vacuum Dryer installation:

 

1. The vacuum chamber casing of the vacuum dryer must be effectively grounded to ensure safe operation.

 

2. The vacuum chamber of the vacuum dryer should be used in an environment with a relative humidity ≤85%RH, free from corrosive gases, strong vibration sources, and strong electromagnetic fields.

 

Key points to note during vacuum dryer use:

 

1. The vacuum chamber working chamber of the vacuum dryer must not be placed in an environment without explosion-proof or corrosion-proof treatment. Flammable, explosive, or corrosive substances must not be placed there for drying. If the items to be dried are moist, a filter should be placed between the vacuum chamber and the vacuum pump to prevent moist gas from entering the vacuum pump and causing malfunction. If the dried items are lightweight and small in size (small particles), a barrier screen should be added to the vacuum port in the working 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 operate for extended periods. Therefore, once the vacuum level meets the requirements for drying the items, first close the vacuum valve, then turn off the power to the vacuum pump. When the vacuum level falls below the requirements for drying the items, reopen the vacuum valve and the power to the vacuum pump to continue vacuuming. This will 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 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 to resolve the issue. 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 instead. If the vacuum dryer is not used for a long time, clean the exposed electroplated parts, apply neutral grease to prevent corrosion, cover it with a plastic film dust cover, and place it in a dry indoor environment to prevent electrical components from getting damp and damaged, which would affect its use.
