• For the pipe length after the header branch (a~f), it is recommended to install the unit so that the difference of the pipe dis-
tance connected to the indoor unit is minimized.
• The large difference in pipe distance can cause performance difference between indoor units.
• After the header branch, you cannot use the Y branch and header branch.
• When the pipe distance corresponding to the farthest indoor unit from the outside unit is 90m or above, you must change the
main pipe diameter according to the outside unit capacity in accordance with the following table.
(This applies to both the liquid and gas pipes.)
