legend
Shaded boxes indicate flooded conditions.
Rated design values. The suction pressure will be lower than design value if outdoor air flow, entering
dry bulb, or entering wet bulb temperatures are lower than design.
noteS:
1. All pressures are listed psig and all temperatures in °F
2. Discharge temperatures GREATER than charted values indicate an UNDERCHARGED system.
3. Discharge temperatures LESS than charted values indicate an OVERCHARGED system.
