*1 Use the ø12.7 (ø1/2) pipe if the piping length from the outdoor unit to the farthest indoor unit is 90 m (295 ft) or longer.
*2 Use the ø12.7 (ø1/2) pipe if the piping length from the outdoor unit to the farthest indoor unit is 40 m (131 ft) or longer.
*3 If the combination units 1, 2, and 3 are in a different order as listed in the table, make sure to use the pipes of appropriate size for the situation.
*4 If the pipe length after the first branching point exceeds 40 m (131 ft) (≤ 90 m (295 ft)), use the one size larger liquid pipe for all pipes from indoor
units to the first branch.
*5 When the vertical separation between the indoor units is 15 m (49 ft) (≤ 30 m (98 ft)), use the one size larger liquid pipe for all pipes from the
lower indoor units to the first branch.
