This chart shows approximate water-side pressure drop for a unit in good repair. The values shown are meant as a guide only. Refer to Prod-
uct Data for the complete performace table. Heating data at entering fluid temperatures below 50°F assumes the use of antifreeze. As a result
of continuing research and development, specifications are subject to change without notice.
