PURPOSE:To contrive reduction of the number of parts and simplification of working property by a method wherein not only the installation of the air-conditioning machine but also the removal of the same are effected by one action from the downward of the installation device and the air conditioning machine is installed by the motions of up-and-down direction. CONSTITUTION:The fixing fitment 3 is provided with a retaining piece 6, a notch groove 7, a long hole 8 orthogonal to the lengthwise direction of the fixing fitment 3 and a hole 9 while the retaining piece 6 is engaged with the notch hole 12 on the side surface of the ceiling suspension type air-conditioning machine 1. A nut 5 can be adjusted from the side surface of the fitment through the notch groove 7 while a support rod 4 penetrates through the long hole 8. According to this method, the fixing fitment 3 is permitted to be moved and the retaining piece 6 can be engaged with the notch hole 12 on the side surface of the ceiling suspension type air-conditioning machine 1 easily. A bolt 10 is penetrated through the hole 9 to fix it to the fixing hole 13 of the air-conditioning machine 1 to support the machine 1 being put thereon. |
