GENERAL FAN PERFORMANCE NOTES
1. Interpolation is permissible. Do not extrapolate.
2. External static pressure is the static pressure difference between the return duct and the supply duct plus the static
pressure caused by any FIOPs or accessories.
3. Tabular data accounts for pressure loss due to clean filters, unit casing, and wet coils. Factory options and accessories
may add static pressure losses. Selection software is available, through your salesperson, to help you select the best
motor/drive combination for your application.
4. The Fan Performance tables offer motor/drive recommendations. In cases when two motor/drive combinations would
work, Carrier recommended the lower horsepower option.
5. For information on the electrical properties of Carrier motors, please see the Electrical information section of this
book.
6. For more information on the performance limits of Carrier motors, see the application data section of this book.
7. The EPACT (Energy Policy Act of 1992) regulates energy requirements for specific types of indoor fan motors. Mo-
tors regulated by EPACT include any general purpose, T--frame (three--digit, 143 and larger), single--speed, foot
mounted, polyphase, squirrel cage induction motors of NEMA (National Electrical Manufacturers Association) design
A and B, manufactured for use in the United States. Ranging from 1 to 200 Hp, these continuous--duty motors operate
on 230 and 460 volt, 60 Hz power. If a motor does not fit into these specifications, the motor does not have to be
replaced by an EPACT compliant energy efficient motor. Variable speed motors are exempt from EPACT compliance
requirements. Therefore, the indoor fan motors for Carrier 48TC**04--16 units are exempt from these requirements.
