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 80
° d.b./67° w.b. entering air temperature in cooling, 70° d.b entering air temperature in
heating. Heating data at entering fluid temperatures below 50° assumes the use of antifreeze.
As a result of continuing research and development, specifications are subject to change without notice.
