When the maximum length of the equivalent refrigerant pipe from the
piping connection kit 1 to the indoor unit is over 100m, the pipe size of gas
and liquid lines from the piping connection kit 1 to first branch should be
increased by one size with reducers (field-supplied).

• In the case that the piping length from the Multi-Kit at the first branch
to the terminal indoor unit is over 40m, the size of the main piping
should be increased by one size with reducers (field-supplied). Refer
to “Piping Branch Restriction” for details.
• Even if the equivalent refrigerant piping length is more than 100m, no
need to increase the pipe size after first branch. If the Multi-Kit size is
larger than the first branch, adjust the Multi-Kit size to the first branch.
In case that the selected pipe size after the first branch is larger than
the pipe size before the first branch, use the same pipe size as before
the branch.

• (*): When the liquid piping length is longer than 15m, use ø9.52 pipe
and reducer (field-supplied).
• The pipe diameter should be the same as the indoor unit piping
connection size.
• Check the corresponding Indoor unit connection sizes.
