NOTES:
1. Type I -liquid refrigerant
Type II -refrigerant gas
2. Style 1 - without manual opening stem
Style 2 - with manual opening stem
3. Capacity rating:
Size 1 - 3.0 tons of refrigerant (TR) (10548 watts (W)) minimum capacity
Size 2 - 7.5 TR (26370 W) minimum capacity
Size 3 - 2.5 cubic feet per minute (CFM) (.0127 meter per second (M3/s)) minimum capacity
