Required Conditions Example Drawin
1.
It is necessary to increase the pipe size between the first branch
kit and the final branch kit. (Reducers must be procured on site)
However, the pipes that are same pipe size with main pipe must
not be increased.
2.
For calculation of Total extension length, the actual
length of above pipes must be doubled. (except
main pipe and the pipes that are not increased)
3.
Indoor unit to the nearest branch kit ≤ 40 m
