PIPE CONNECTIONS BETWEEN INDOOR AND OUTDOOR UNIT
33
ENGLISH
Header Method
Example : 6 Indoor Units connected
Ⓐ
: Outdoor Unit
Ⓑ
: 1st branch
Ⓒ
: Indoor Units
Ⓓ
: Sealed piping
L 150m
H 50m
40m
• * : Assume equivalent piping length of Y branch to be 0.5m, that of header to be 1m, calcu-
lation purpose
• Indoor Unit should be installed at lower position than the header.
WARNING
Pipe length after header branching (a~f)
It is recommended that difference in length of the pipes connected to the Indoor Units is
minimized. Performance difference between Indoor Units may occur.
