PROBLEM TO BE SOLVED: To shorten the time required before performing refrigerant recovery work by avoiding removal work of a machine chamber cover. SOLUTION: A cover 30 has a core 34 formed as a lid part formed thinner than the other part and surrounded by an annular thin-walled part 33, corresponding to a process pipe 25 and a refrigerant pipe 23. A pull tab 35 is mounted to the upper part of the core 34 through a rivet, and the thin-walled part 33 is ruptured by pulling the pull tab 35. Further, the rupture reaches the lower end by pulling the pull tab 35 downward to the outside, and the core 34 is taken off the cover 30 to form an opening. COPYRIGHT: (C)2003,JPO
