- The vacuum pump should be kept on during system operation.
- When the oxygen concentration in the chamber exceeds 200PPM, the equipment maintenance personnel should be notified to perform system operation, otherwise the H2O and O2 purification system will be damaged.
- Do a check before starting the cycle to see if it is in a chamber condition or regeneration. As the operation mentioned above is in progress, it is absolutely forbidden to perform the circle.
- Two purification columns cannot be regenerated at the same time.
- Before regeneration, make sure that the glove box has been cleaned by inert gas (H2O <200ppm) to ensure sufficient regeneration gas supply. The regeneration gas pressure is 0.06-0.08 mpa.
- Before starting regeneration, please make sure that the corresponding purification column cycle is closed.
- The regeneration process takes 24 hours. Once it can’t be disconnected, the regeneration gas should be used 3-6 hours after the regeneration starts. Pay attention to the amount of regeneration gas, adjust the pressure of the regeneration gas appropriately, and ensure the sufficient supply of regeneration gas in these 3 hours. The origin of regeneration can be turned off after 6 hours.
- The vacuum pump cannot be turned off during regeneration. Do not touch the top of the purification column to prevent burns.
- Once the regeneration is terminated unexpectedly, please ensure that the regeneration and circulation of the purification column cannot be restarted within 12 hours, otherwise the equipment will be damaged.
- Protect the working gloves from damage during operation.
