lThe amount of refrigerant put into the outdoor unit at the factory is equivalent to that which fills up 20m length of refrigerant pipe.
lIf the length of refrigerant pipe is 20m or less, addition of refrigerant at the installation site is unnecessary. If the length of the pipe

exceeds 20m, add the refrigerant R-22.
lOvercharge or undercharge of refrigerant in the outdoor unit will cause malfunction of the compressor. The prescribed amount of
the replenishment of the refrigerant is shown in the table above.
