PROBLEM TO BE SOLVED: To install the subject unit without interfering with other equipment in relationship to the installation position of the unit by positioning the tips of connecting pipes of a circulating pump connected to an outward pipe and a return pipe in the short sidewall of the storing unit and forming openings. SOLUTION: In a unit case 15, one end of a suction connecting pipe 17 as a connecting pipe is connected to a suction port 16 of a circulating pump P, and one end of a projecting connecting pipe 19 as a connecting pipe is connected to a projecting port 18 of the circulating pump P. The other end of the suction connecting pipe 17 is taken as a connecting end 17a to the circulating pump, and the projecting connecting pipe 19 is forked in the midway to form projecting branch pipes 19a, 19b. These other ends are taken as the connecting ends 19c, 19d to the circulating pipe, and three connecting ends 17a, 19c, 19d are projected out from the end wall 43 which is the short sidewall of the unit case to be open, and arranged on the vertical center line in substantially the same plane in the vertical direction. |
