Selection of pipe materials and size
• Selection of pipe material
Material: Phosphorus deoxidation seam-less pipe
• Capacity code of indoor and outdoor units
• For the indoor unit, the capacity code is decided at each capacity rank. (Table 1)
• The capacity codes of the outdoor units are decided at each capacity rank. The maximum No. of connectable
indoor unit and the total value of capacity codes of the indoor units are also decided. (Table 2)
Compared with the capacity code of the outdoor unit, the total value of capacity codes of the connectable indoor
units differs based on the height difference between the indoor units.
• When height difference between the indoor units is below 15m: Up to 135% of capacity code (Equivalent to HP)
of the outdoor unit. (in case of MMY-MAP1202FT: 120% or less)
• When height difference between the indoor units is over 15m: Up to 105% of capacity code (Equivalent to HP) of
the outdoor unit.
