PROBLEM TO BE SOLVED: To increase strength of an operating valve fixture by supporting one side of the operating valve fixture with a hand grip part provided at a position lower than that of the one side of the operating valve fixture. SOLUTION: While a hand grip part 13 is located at a position slightly lower than that of an upper end of a heat exchanger 3, a supporting plate 9a comprising a suspending part suspending along an outline of the heat exchanger 3 and a contact part coming in contact with an interior wall upper surface of the hand grip part 13 by a front edge of the suspending part being bended outward is provided on one side of an operating valve fixture 9. Thereby the one side of the operating valve fixture 9 used to be not firmly fixed has a structure firmly supported by bringing the supporting plate 9a into contact with the interior wall upper surface of the hand grip part 13. A structure is realized, wherein, when connecting piping is connected with an operating valve 9' with a tool, the operating valve fixture 9 is not wobbled and has no possibility of damage, and connection work is not disturbed by the hand grip part 13. |
