Capacities rated using 10°F (5.6°C) TD & 100°F (38°C) liquid temperature.
Capacities at other TD within a range of 8 to 15 °F (4.4 to 8.3°C) are directly proportional to TD, or use formula: Capacity = Rated capacity ÷ 10 x TD.
For capacities at TD outside of range 8 to 15 °F (4.4 to 8.3°C), or liquid temperature lower than 75°F (24°), consult factory.
Capacities for R448A, R407A and R407C are based on mean temperature. Mean temperature is the average temperature between the saturated suction
temperature and the temperature feeding the evaporator. For dew point ratings, consult factory.
For R449A, use R448A data.
