Note: When calculating refrigerant charge, the first step is
to determine the unit charge, and if the unit charge
includes the first 25 foot of pipe. This information
may be located in the catalog and IOM. If the unit
charge does include 25 foot of pipe, the field
installed refrigerant line calculations should be
reduced accordingly. The discharge line need not be
calculated unless it is a remote evaporator
application. The unit charge, suction charge, liquid
charge, and discharge line (if required) may then be
summed for a refrigerant charge estimate.
