8.3 Change in Capacity (Reference)
8.3.1 RY35F, 50G(A), 60G(A), 71KU
„ Capacity correction factor by the length of refrigerant piping (Reference)
The cooling and the heating capacity of the unit has to be corrected in accordance with the length of
refrigerant piping. (The distance between the indoor unit and the outdoor unit)
Notes: 1. line: Correction factor for heating capacity
line: Correction factor for cooling capacity
2. The correction factor remains the same whether the outdoor unit is to be installed above or below the
indoor unit.
3. You cannot extend the refrigerant piping exceeding the limit shown in the above table. However, if the
unit has a limited length of refrigerant piping less than 50m, refer to the correction factor within the
range of its limitation.
