Calculation : Xg=20g/mx(Refrigerant piping length(m)-40)
Refrigerant pipe diameter is different according to indoor unit to be connected. When using extension pipes,refer to the
tables below.
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 17-1.
