This chart shows approximate temperatures and pressures for a unit in good repair . The values shown are meant as a guide only and should n ot be used to estimate system charge. Thischart assumes rated air flow and 80º D.B/67º W.B. Entering air temperature
in cooling, 70_F D.B entering air temperature in heating. Heating data at entering fluid temperatures below 50_F assumes the use of antifreeze. Asa result of continuing research and development, specifications are subject to change without
notice.
