5.4 Diameters of outdoor unit connecting pipe
The horizontal straight pipe distance that connets to indoor unit
behind the manifold should be at least 0.5m
Use the maximum indoor and outdoor connecting pipe diameter.
CAUTION
The horizontal straight pipe distance between angle branch and
its adjacent manifold should be at least 0.5m
The horizontal straight pipe distance between 2 adjacent 2
