16 Refrigerant Charging Chart Legend for Heating Mode of Operation:
Shaded boxes indicate flooded conditions.
Rated design values. The suction pressure will vary from design value if outdoor air flow, entering dry bulb, or entering wet bulb temperatures vary.
1.All pressures are listed psig and all temperatures in °F
2.Discharge temperatures greater than charted values indicate an undercharged system.
