Starting from a state where a supply valve 53 at the air supply facility 50 and a discharge valve 70 at the discharge facility 3 are closed, the supply valve 53 is opened to conduct a leak test with the piping 10, 11 and 12 supplied with air from the air supply facility 50. Then, the discharge valve 70 is opened to eliminate a foreign matter inside the piping 10, 11 and 12 with an air flow generated therein when the air used in the leak test is discharged and additional air is supplied from the air supply facility 50. |
