4-5. CORRECTING CAPACITY FOR CHANGES IN THE LENGTH OF REFRIGERANT PIPING
(1) During cooling, obtain the ratio (and the equivalent piping length) of the outdoor units rated capacity and the total in-use
indoor capacity, and find the capacity ratio corresponding to the standard piping length from Figure 6 to 8. Then multiply
by the cooling capacity from Figure 4 and 5 in "4-2. CORRECTION BY TEMPERATURE" to obtain the actual capacity.
