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.
• When the height difference between the indoor units is over 15m: Up to 105% of the capacity code.

• When using the conventional
fl
are tool, to connect R410A pipes with
fl
aring, make a margin approx. 0.5mm
longer than that of an R22 pipe so that the
fl
are size matches the one speci
fi
ed. It is convenient to use a copper
pipe gauge for size adjustment of the extruding margin.
• The
fl
ared supplied attachment pipe (Ø19.1) must be used to connect with discharge-side gas pipe valve
(Ø19.1). (MAP120 to MAP200) Do not use half hard or hard materials instead of the supplied attachment pipe.
The half hard or hard materials may be cracked and may cause leakage of refrigerant when it is
fl
ared.
• Use the
fl
are nut provided with the product.
• After
fl
aring the connection, be sure the
fl
ared part is not damaged, deformed, uneven, or
fl
attened, and that
there are no cutting chips on it.
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
suction side gas line.
