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 ow and 80º d.b./67º
w.b. entering air temperature in cooling, 70º d.b. entering air temperature in heating. Heating data at entering uid
temperatures below 50º assumes the use of antifreeze. As a result of continuing research and development,
specications are subject to change without notice.
