This chart shows approximate temperatures and pressures for a unit in good repair. 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.
