Shaded boxes indicate flooded conditions.
Rated design values. The suction pressure will vary from design value if indoor air flow, entering dry bulb,
or entering wet bulb temperatures are lower than design.
1. All pressures are listed in psig and all temperatures in ° F
2. Discharge temperatures greater than charted values indicate an undercharged system.
3. In Cooling Mode suction pressure will be lower than design value if indoor air flow, entering dry bulb, or entering
wet bulb temperatures are lower than design.
4. In Heating Mode, charge should be weighed in. It is strongly recommended to verify charge in Cooling Mode
at ambient above 70°F.
