Notes:
1. Shaded areas indicate non-standard BHP or RPM selections. Contact your local Trane representive for more information.
2. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static must be added to appropriate component
static pressure drops, (evaporator coil, filters, optional economizer, optional heating system, optional roof curb).
3. Maximum static pressure leaving the rooftop is 4.0’’ H20 positive. The static pressure drops from the supply fan to the space cannot exceed 4.0’’ H20.
4. Minimum motor horsepower is 30 hp.
5. See RT-EB-104 for further details.
