NOTES:
1. Boldface indicates field-supplied drive required (see Note 3).
2.
indicates field-supplied motor and drive required.
3. Factory-shipped drive range is 930 to 1205 rpm. Other rpms may require
a field-supplied drive.
4. Values include losses for filters, unit casing, and wet coils.
5. Extensive motor and electrical testing on these units ensures that the full
range of the motor can be utilized with confidence. Using your fan motors
up to the wattage ratings shown will not result in nuisance tripping or
premature motor failure. Unit warranty will not be affected. See

6. Use of a field-supplied motor may affect wire sizing. Contact your Carrier
representative to verify.
7. To convert Watts to Bhp:
Watts x Motor Efficiency
Bhp =
Motor Efficiency: .81
8. Interpolation is permissible. Do not extrapolate.
9. Static pressure losses (i.e., economizer, electric heater) must be added to
external static pressure before entering Fan Performance table.
