PROBLEM TO BE SOLVED: To provide a technology for appropriately connecting and fixing a tank unit with a heat source machine unit regardless of the environment where both units are disposed.SOLUTION: When a tank unit and a heat source machine unit are juxtaposed to each other and a first fitting 40 and a second fitting 70 are assembled, a screw can be screwed from the outside of a second side plate 74 into a second through-hole 82 and a first screw hole communicating to each other, and also a screw can be screwed from the inside of a first side plate into a first through-hole and a second screw hole 80 communicating to each other. Thereby, by working from the outside of the second side plate 74 at one side (also from the inside of the first side plate at the other side), the second side plate 74 at one side and the first side plate at one side can be connected by screw-cramping, and the first side plate at the other side and the second side plate at the other side can be connected by screw-clamping. |
