This chart shows approximate temperatures and pressures for a unit in good normal operation. The values shown are meant as
a guide only and should not be used to estimate system charge. This chart assumes rated air flow and 80º D.B/67º W.B. Entering
air temperature in cooling, 70º D.B entering air temperature in heating. Heating data at entering fluid temperatures below 50º
assumes the use of antifreeze. As a result of continuing research and development, specifications are subject to change without
notice.
