2. Pipe “b” diameter (between manifold pipes)
Note: Adjust the diameter on job site (changing pipe is needed)
When the latter indoor total capacity is less than 14.0kw, pipe b will use the specication as the pipe a.
3. Pipe “c” diameter (main pipe, between outdoor branch pipe and the rst manifold pipe)
Note: When the distance from outdoor to the farthest indoor is over 80m, the enlarged diameter should be chosen
for the main pipe.
