APPENDIX 4 - ADDITIONAL REFRIGERANT CHARGE FOR CONVENTIONAL
FAN COILS
When matching the FMA4 and FMC/FMU indoor units, the 12K units require 12.4oz. (350g) more refrigerant due to the indoor coil’s size.
No refrigerant addition is necessary for the FV4 (any size).
All the outdoor units are shipped from the factory pre-charged for 25ft. of piping length. See the outdoor unit’s installation instructions for
additional charge requirements on longer piping lengths.
