<p>PROBLEM TO BE SOLVED: To eliminate the forgotten removal of a filter upon installation work and prevent the reduction of capacity or the trouble of a duct type air conditioner due to the forgotten removal. SOLUTION: When a duct is connected to a suction port upon the installation at site and a duct joint 7 is removed once from a casing body, divided bodies 9, 9 are separated into a plurality of pieces whereby the filter 11 is released out of the duct joint 7 inevitably. Thereafter, the divided bodies 9, 9 are attached in a direction reverse to the last direction in a condition that the duct joint 7 is projected from the casing body. When the work is controlled in such a manner, the filter 11 is released inevitably when the duct joint 7 is removed from the casing body 1 whereby the filter 11 will not be attached as it is to the casing body as far as the same is attached intentionally when the duct joint 7 is re-attached. Accordingly, the installation of the air conditioner without removing the filter 11 due to a human error can be prevented.</p> |
