*1, *2 If the maximum extension equivalent length is over 90 m or the main pipe maximum equivalent length is
over 60 m, the diameter of the pipe between the outdoor unit and the
fi rst branch must be ranked up in
accordance with the below table.
*3 The maximum length of the
indoor unit connection pipe
depends on the indoor unit
capacity.
(Please refer to the table below.)

Caution
1. The pipe size between branches should not exceed the diameter of the pipe between outdoor unit and fi rst
branch.
2. After the header branch, don’t implement another header branch.
3. After the header branch, don’t implement another line branch.
