CONSTITUTION:When an installing plate 5 is applied to fix an indoor unit 1 to an interior wall, at first an installing plate 5 is abutted against the interior wall, screws are inserted into through-holes 7 of the installing plate 5 and then the plate is fixed. When a coolant pipe extending from an indoor unit 1 is to be arranged at a right part, a piping hole 9 is made at a wall around a crossing point 18 on an extended line 17 of a mark 10. In turn, when the coolant pipe is to be arranged at a left part, an auxiliary plate 11 is bent, a pencil etc. is inserted into a hole 16 of a round shaped part 15 to mark a wall. Then, the auxiliary plate 11 is returned back to its original state and then a piping hole 12 is made around the previous mark. An engagement piece 4 of the unit 1 is fitted to the engagement part 6 of the installing plate 5, the coolant pipe of the indoor unit 1 is inserted into the piping holes 9 and 12 to cause its extremity end to the projected out of a room. |
