### **Installation and Operation Instructions**
1. **Pressure Setting**: After powering on, press the "pressure setting" button. Use the “+†and “-†keys to adjust the desired pressure value. Press “Enter†to save. Adjust the lower limit and exit after saving.
2. **Water Injection**: Open the water injection cover and fill the tank with pure water until full. Start the pressurization process and open the pressure regulator to allow water into the high-pressure chamber.
3. **Testing Process**: Secure the sample using a torque of 320 N·m. Start the pump and apply pressure up to the specified level. Perform a total of 6 pressurizations, with no additional pressure if the pressure drops between cycles.
4. **Test Duration**: After 6 hours of pressurization over a 24-hour period, maintain the required pressure for 30 minutes. Observe the flange area for any signs of leakage and record the results.

### **Post-Test Procedures**
After completing the test:
- Open the high-pressure chamber and release the pressure through the relief valve.
- Clean the instrument and dry the sample slot. Apply anti-rust grease to the bottom plate.
- If the equipment will not be used for an extended period, drain all water from the system to prevent damage from freezing.
