<p>PURPOSE:To reduce man-hours for pipeline connecting work and quicken posi-. tioning work by a method wherein an arm is supported vertically by an installation frame for an air-conditioning machine, embedded into a wall, so as to be swingable inwardly and outwardly With respect to the installation frame. CONSTITUTION:A wall 1 is provided with a rectangular hole 1a while a rectangular installation frame 2 is buried into the hole 1a. The installation frame 2 is provided with an U-shape arm 4 and the arm 4 is swung outwardly to fit the other side of the air-conditioning machine 3 and fit one side of the air- conditioning machine 3 into the arm 4 whereby one side of the air-conditioning machine 3 is received and supported by the arm 4 under a condition that the side is extracted out of the installation frame 2 forwardly. Accordingly, a worker for receiving and supporting the air-conditioning machine 3 becomes unnecessary. According to this method, man-hours for pipeline connecting work can be reduced and the positioning work in the installation work of the air- conditioning machine 3 can be quickened.</p> |
