Coupling size of brazed pipe
(Unit: mm)
Selection of pipe size
◆Capacity code of indoor and outdoor units
Selection of pipe material
• 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 number of connectable
indoor units and the total value of capacity codes of the indoor units are also decided. (Table 2)
NOTE
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 the height difference between the indoor units is 15m or less: Up to 135% of the capacity code (Equivalent
to HP) of the outdoor unit (Equivalent to HP) of the outdoor unit
• When the height difference between the indoor units is over 15m: Up to 105% of the capacity code
