PURPOSE:To enable providing service inspection of a lower heat exchanger unit while a plurality of heat exchanger units are held one upon another in a mounted state by setting apart at a larger distance main struts connecting an upper supporting frame and a lower supporting frame than the measurement of the panel of the heat exchanger unit mounted on the lower supporting frame and by providing also subsidiary struts. CONSTITUTION:When service inspection is provided to the lower unit 1 of two heat-exchanger units 1, 2 mounted one upon the other, subsidiary struts 10 are removed in the first place. After removal of the subsidiary struts 10, main struts 9 keep holding the two heat-exchanger units 1, 2 one upon the other. The main struts 9 are set apart at a distance C which is larger than the width B of the front panel 24 of the lower heat-exchanger unit 1 so that, by unscrewing the side plates 25 of the lower unit 1, the front panel 24 of the lower unit 1 can be removed while the two units 1, 2 are held one upon the other. In this way the lower unit 1 can be made ready to received service inspection. |
