For SI:
1 British thermal unit per hour = 0.2931 W, °C = [(°F) - 32]/1.8.
 
"Cap" = The rated cooling capacity of the product in Btu/h. If the unit's capacity is less than 7000 Btu/h, use 7000 Btu/h in the calculation. If the unit's capacity is greater than 15,000 Btu/h, use 15,000 Btu/h in the calculations.
a
Chapter 12 of the referenced standard contains a complete specification of the referenced test procedure, including the referenced year version of the test procedure.
b
Replacement unit shall be factory labeled as follows: "manufactured for nonstandard size applications only; not to be installed in new standard projects" or "manufactured for replacement applications only: not to be installed in new construction projects." Replacement efficiencies apply only to units with existing sleeves less than 16 inches (406 mm) in height and less than 42 inches (1067 mm) in width.
