*Note: All pressures are listed in psig. and all temperatures in deg. F.

— Shaded Boxes indicate flooded conditions

— Rated Design Values. Suction Pressure will be lower than design value if indoor air flow, entering dry bulb, or entering wet bulb temperatures are lower than design.

—Discharge temperatures greater than charted values indicates a refrigerant undercharge.
