G Refrigerant pipe diameter is different according to indoor unit to be connected. When using extension pipes,refer to the
tables below.
G When diameter of refrigerant pipe is different from that of outdoor unit union, use optional Different-diameter pipe.
For further information on Different-diameter pipe,see 15-1.
