Notes:
• Shaded areas represent selectable area.
Contact your local Trane® representative for
more information.
• 60 ton units with gas heat use the 30" DDP fans.
See
• Supply fan performance curve 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 relief fan, optional heating
system, optional cooling only extended casing,
optional roof curb).
• Maximum Cfm (for cULus approval) as follows:
60 ton - 27,000 Cfm.
• Minimum motor horsepower is 10 hp (2 x 5 hp
motors). Maximum motor horsepower is 40 hp
(2 x 20 hp motors). Maximum fan RPM is 2,200.
