It is required to size up the liquid piping between the first branch kit and the last. In contrast to multi BS units, BS1Q units are not considered branch kits. If the increased pipe size is larger than the pipe size of the main pipe, also increase the size of the main pipe. 1.4 When the piping size is increased, the piping length has to be counted as double. he total piping length has to be within limitations. 1.5 he piping length difference between the nearest indoor unit to the outdoor unit and the farthest indoor unit te the outdoor unit is m. 2.
