The first side panel 53a and the second side panel 53b each have a wall body fixed to the frame in each side of the heat exchanger. An auxiliary casing 35 is movably attached to the wall body. The auxiliary casing 35 is displaced forward relative to the heat exchanger to form space 109 from a wall face in installation. |
