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, as shown in the tables above. 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, Bryant recommended the lower horsepower option. 5. For information on the electrical properties of Bryant motors, please see the Electrical information section of this book. 6. For more information on the performance limits of Bryant 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. Motors 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 Bryant 580J04- --14 units are exempt from these requirements. 48 FAN PERFORMANCE Table 33 – 580J*04 1 PHASE 3 TON HORIZONTAL SUPPLY CFM RPM BHP FieldSuppliedDrive1 900 553 0.14 975 575 0.16 1050 597 0.18 1125 620 0.21 1200 643 0.23 1275 667 0.27 1350 69...
