Main quality control project list:
1. Check all parts before assembling.
2. Charge nitrogen to test leakage and pressure maintaining after welding system.
3. Vacuumize, the vacuum pressure ≤30Pa
4. Leakage detection by halogen after charge refrigerant.
5. Safety testing: High-voltage insulation test and ground resistance.
6. Operation testing, record refrigerant pressure, temp. etc.
7. Inspect inside unit’s cleanliness and appearance.
