■ Limits of pipe length and difference in height
 Standard Model (ARUN****SS0)
 Compact Model (ARUN****SL0)
Note
• * : Assume equivalent piping length of Y branch to be 0.5m, that of header to be 1m, calculation purpose.
• ** : To apply Conditional Application
WARNING
When the below condition is satisfied, the diameter of main pipe (A) must be increased accordingto below
table.
• The equivalent length between outdoor unit and the farthest indoor unit is 90m or more
(Liquid and Gas pipes are increased)
* Compact models are not applied.
