*Based on Nominal 400 CFM per ton per circuit ariflow and 70°F EAT heating and 80/67°F cooling.

** Cooling air and water numbers can vary greatly with changes in humidity.

*** Water temperature difference based upon 1.5 - 3 GPM per ton of active circuit water flow.

**** Using liquid line pressure.
