Note 1: “(6), (8), (10), (12)” in the combination table indicate the horsepower of the main units (DC inverter type). “8, 10, 12”
indicate the horsepower of sub units (constant speed type).
2: If future extension of the system is expected, select tubing diameters that are based on total horsepower after extension.
However, extension that requires increasing the tubing size by 2 steps is not possible.
3: The balance tubing (outdoor unit tubing) size is
φ9.52.
■ Size of tubing (LO1, LO2) between outdoor units
Select the size of tubing between outdoor units based on the main tubing size (LA) as given in the table above.
Table 1-11b Main Tubing Size After Distribution (LB, LC...)
Note: 1. In case the total capacity of connected indoor units exceeds the total capacity of the outdoor units, select the main
tubing size for the total capacity of the outdoor units. (Especially the main tubing segments of LA, LB and LF.)
