The nominal capacity is based on the following conditions:
Refrigerant Evaporating Temperature Condensing Temperature Subcooling
R-22, R-134a, R-404A, R-507 +40°F +100°F 2°F
R-407C +40°F bubble point +100°F dew point 2°F
Remarks: Note 1: Bi-ow versions are not released for hot gas bypass applications.
Note 2: EX4, EX5, EX6, EX7 and EX8 must be installed with motor downward in hot gas line applications.
This insures the valve life expectancy.
