In this case, before connecting each pipe 4 to the indoor unit 1 and the outdoor unit 3, the pipe 4 is covered from the outside of the heat insulating material 5. Before use, the cover 6 is folded in a bellows-like manner as shown in FIG. 4, and in this state, the cover 6 is unrolled and expanded into a tubular shape so that the end of the pipe 4 in the longitudinal direction is extended. It is something to cover from the part. In this case, a coating 6 used to cover the heat insulating material 5 outside the two pipes 4 and 4 arranged in parallel in the vertical direction along the wall surface of the building together with an electric wire from the outside. As is apparent from the above description, the coverings 6 used to cover the heat insulating material 5 on the outside of each bifurcated pipe 4 have different inner diameters from each other, and are arranged vertically along the wall surface of the building. The work of covering the heat insulating material 5 on the outside of the two pipes 4 and 4 arranged in parallel with each other from the outside together with the electric wire and the work of covering the heat insulating material 5 on the outer side of each pipe 4 which is bifurcated are separate. To be done.

Incidentally, the covering body 6 folded in the bellows shape.
Is set and attached to the outside of the short tubular guide member 7 as also shown in FIG. 4, so that the guide member 7 can be attached to the heat insulating material 5 outside the pipe 4 shown in FIGS. 5 and 6. The guide member 7 is attached to the other end side of the heat insulating material 5 in a state where it is fitted onto one end of the heat insulating material 5 and one end of the covering body 6 set on the guide member 7 is brought into close contact with one end of the heat insulating material 5. By sliding, the cover 6 is sequentially fed out from the guide member 7, and the heat insulating material 5 can be covered in the length direction. More specifically, the cover 6 is a guide member 7
It is set so as to be able to be extended around the cylindrical portion so that the overlapping direction is parallel to the axis of the cylindrical portion.
