CONSTITUTION:A tightening tool 9 of a cylindrical folded-back part 9 of a cleaning cover 1 is closely tightened around a package 13 into water tightness, and cylindrical members 5, 5, 5 provided parallely to a work hole 3 are disposed inwardly of the cleaning cover 1. A hose insertion inlet is opened at a proper location of the cleaning cover 1, and a lower side part of the cleaning cover 1 is bound with a cord 17 as a cleaning water outflow passage 19 which is then coupled with a drainage passage 23. A worker inserts his both hands from the work holes 3, 3 into the cylindrical members 5, 5 and further inserts both hands into hand bag parts 5a, 5a mounted on the tip end to grip a cleaning base and blow off cleaning water to a heat exchanger fin 14 and the surroundings of the former for washing off dust, etc. |
