Table 11 — Fan Performance, 50TFF009 Standard Motor — Vertical Discharge Units

LEGEND

*Motor drive range: 685 to 935 rpm. All other rpms require field-

supplied drive.

NOTES:

1. Boldface indicates field-supplied drive is required.

2.

indicates field-supplied motor and drive are required.

3. Maximum usable watts input is 2120 and maximum continuous

bhp is 2.40. 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 rat-
ings shown will not result in nuisance tripping or premature
motor failure. Unit warranty will not be affected. For additional
information on motor performance refer to Table 8.

4. Values include losses for filters, unit casing, and wet coils. See

Table 7 for accessory/FIOP static pressure information.

5. Use of a field-supplied motor may affect wire sizing. Contact

your Carrier representative to verify.

6. Interpolation is permissible. Do not extrapolate.
