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.
