Notes
˖
a. The refrigerant charge mentioned in the technical data
does
not includ
additional charge required for the indoor
unit and the refrigerant pipe.
b. The amount of the additional refrigerant charge depends on the diameter and length of the liquid
refrigerant pipe
installed
.
c. Record the additional refrigerant charge for future maintenance.
1). Calculation of the Additional Refrigerant Charge
If the total refrigerant pipe length (liquid pipe) is smaller than that listed in the table below, no additional
refrigerant will be charged.
