What should be done if the laboratory is shut down for a long time during holidays?

It is recommended to follow the following steps for shutdown during holidays: 1. Close the inlet valve and cut off the power supply; 2. Drain the stored water in the RO membrane and pipeline (to prevent bacterial growth); If the shutdown exceeds 7 days, it is recommended to remove the RO membrane and soak it in a 1% sodium bisulfite protective solution; Before restarting, rinse the system for 30 minutes and drain the initial water production. For specific operations, please refer to the "Holiday Shutdown and Startup Operation Guide" (available for download from the official website).
