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 7,000 Btu/h, use 7,000 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 6 contains a complete
				specification of the referenced standards, which include test procedures,
				including the referenced year version of the test procedure.
b Nonstandard size units must be
				factory labeled as follows: "MANUFACTURED FOR NONSTANDARD SIZE APPLICATIONS
				ONLY: NOT TO BE INSTALLED IN NEW STANDARD PROJECTS." Nonstandard size
				efficiencies apply only to units being installed in existing sleeves having an
				external wall opening of less than 16 inches (406 mm) high or less than 42
				inches (1067 mm) wide and having a cross-sectional area less than 670 square
				inches (0.43 m2).
c The cooling-mode wet bulb temperature
				requirement only applies for units that reject condensate to the condenser
				coil.
d "Cap" in EER and COPH equations for
				PTACs and PTHPs means cooling capacity in Btu/h at 95°F outdoor dry-bulb
				temperature.
