Notes:

1.Supply fan performance table includes internal resistance of air handler. For total static pressure determination, system external static pressure must be added to appropriate component sp drops (chilled water coil, filters, optional economizer, optional heating system).

2.Maximum SP leaving the air handler is 5.5" H20 positive.

(i)Outlined area indicates nonstandard BHP or RPM selections. Contact a local Trane representative for more information.
