Appendix C - Fan Performance - Carrier WeatherMaster 50HCQ04-12 Service And Maintenance Instructions

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
can add static pressure losses.
4. The Fan Performance tables offer motor/drive recommen-
dations. In cases when two motor/drive combinations
would work, Carrier recommended the lower horsepower
option.
5. For information on the electrical properties of Carrier's
motors, please see the Electrical information section of
this book.
