NOTE:
When maximum length of the equivalent refrigerant pipe (L1) from the outdoor unit/manifold pipe1 to the indoor unit is over
328 ft. (100m), the pipe size of high/low pressure gas and liquid line from basic unit/manifold pipe1 to rst branch should be
increased one size with the reducer (eld-supplied).

NOTE:
Even if the equivalent refrigerant piping length (L1) is more than 328 ft. (100m), no need to increase the pipe size after rst
branch. If the branch pipe size is larger than the rst branch, adjust the branch pipe size to the rst branch. In case that the
selected pipe size after the rst branch is larger than the pipe size before the rst branch, use the same pipe size as the one
before the branch.

NOTE:
(1) When the liquid piping length is longer than 49.2ft.(15m), use Φ3/8(9.53) pipe and reducer (eld-supplied) instead of
Φ1/4 (6.35) pipe.
(2) The pipe diameter should be the same as the indoor unit piping connection size.
