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
airflow 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.
