れる。(*) The unit body is installed in the ceiling space by pushing the action unit body into the ceiling space through the ceiling hole and screwing the nut onto the hanging fixture that has been fixed in advance to the ceiling space. After that, the installation work of the air conditioning unit is completed by attaching the decorative panel to the unit body and drilling the ceiling hole. However, as mentioned above, when installing the unit body in the ceiling space, the installation height of the unit body is a guideline. Because of this, there is a risk that a gap may be created between the decorative panel and the lower surface of the ceiling. If such a gap is created, open the cover of the decorative panel, insert the accessory operating tool straight through the service opening, fit the fitting part formed at the tip of the operating tool into the nut, and then insert the operating tool below the service opening. By surrounding the operating tool while observing the gap between the decorative panel and the lower surface of the ceiling, the unit body is installed and fixed at a predetermined height position where the decorative panel comes into contact with the lower surface of the ceiling.
