* When using the conventional flare tool, to connect R410A pipes with flaring, make a margin approx. 0.5mm
longer than that of an R22 pipe so that the flare size matches the one specified. It is convenient to use a copper
pipe gauge for size adjustment of the extruding margin.
CAUTION
Wrap the ball valve in a wet cloth to keep it cool and prevent the heat from the
torch from damaging it when connecting the pipe to the ball valve on the gas line.

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
Cloth
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.
Torch
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
