Method 1:
1. Install the new filter element into the filter housing and fill it with pure water.
2. Seal the system and pressurize to 0.5-0.55 MPa, maintaining pressure for 5-10 minutes.
3. Invert the filter and maintain pressure for 5-10 minutes.
4. Release the pressure and perform an integrity test.
Method 2:
1. Rinse the inner and outer shells of the filter element with pure water for 1-3 minutes.
2. Immerse the filter element in a container filled with pure water, ensuring it is submerged for 5-10 minutes. Every 2-3 minutes, shake the filter element up and down (invert it, ensuring the central rod is filled with water) to remove air bubbles.
3. Install the filter element in the filter housing, fill it with water, seal the system, pressurize to 0.5-0.55 MPa, and maintain pressure for 5-10 minutes. Release the pressure.
4. Place the filter element in the filter housing (bottom up), fill it with water, seal the system, pressurize to 0.5-0.55 MPa, and maintain pressure for 5-10 minutes. Release the pressure.
5. Perform an integrity test.
Note: After step 3, you can consider testing the integrity. If it passes, step 4 can be omitted.
