Table 8. Factory Charge
The outdoor condensing units are factory charged with the system charge required for the outdoor condensing unit, ten (10) feet of tested
connecting line, and the smallest rated indoor evaporative coil match. Always verify proper system charge via subcooling (TXV/EEV) or
superheat (fixed orifice) per the unit nameplate.
Table 9. Required Refrigerant Line Length
Determine required line length and lift. You will need this to
determine the subcooling charging corrections later in the
installation process.
Total Line Length = ___________________________Ft.
Total Vertical Change (lift) = ____________________Ft.
