NOTE(S):
a. These operating temperatures and pressure charts show approximate temperatures and pressures for a unit on good repair. The values shown are
meant as a guide only and should not be used to estimate system charge.
b. This chart assumes rated air flow and 80°F db/67°F wb entering air temperature in cooling, 70°F db entering air temperature in heating.
c. Heating data at entering fluid temperatures below 50°F assumes the use of antifreeze. As a result of continuing research and development, specifi-
cation are subject to change without notice.
