Charge (A)
(A) to (C) parameters are shown in below table.
The following table shows refrigerant amount for every 5 feet of line. Choose connected indoor coil type, Liquid/Suction pipe
diameter and line set length. Calculate charge amount by linear approximation in between line set length mentioned below
table.
* Factory Charge (B) may differ from the value specified on the unit name plate.
In that case, calculate the Additional Charge (C) as to keep the Total Refrigerant Charge (A) indicated in the table.
