For SI: 1 square foot = 0.0929 m2, 1
				cubic foot = 0.02832 m3, °C = (°F -
				32)/1.8.
a The meaning of the letters in this
				column is indicated in the columns to the left.
b Ice cream freezer is defined in
				DOE  10 C.F.R. Part 431.62  as a commercial freezer that is designed to operate
				at or below -5°F and that the manufacturer designs, markets or intends for
				the storing, displaying, or dispensing of ice cream.
c Equipment class designations
				consist of a combination [(in sequential order separated by periods
				(AAA).(BB).(C))] of:
(AAA) An
			 equipment family code where:
VOP = Vertical open
SVO = Semi-vertical open
HZO = Horizontal open
VCT = Vertical transparent doors
VCS = Vertical solid doors
HCT = Horizontal transparent doors
HCS = Horizontal solid doors
SOC = Service over counter
(BB) An operating mode code:
RC = Remote condensing
SC = Self-contained
(C) A rating temperature code:
M = Medium temperature (38°F)
L = Low temperature (0°F)
I = Ice cream temperature (15°F)
For example, "VOP.RC.M" refers to the "vertical-open,
				remote-condensing, medium-temperature" equipment class.
d V is the volume of the case
				(ft3) as measured in AHRI 1200, Appendix C.
e TDA is the total display area of
				the case (ft2) as measured in AHRI 1200, Appendix
				D.
