Table 13 — Fan Performance, 50TFF012 — Vertical Discharge Units

LEGEND

*Standard motor drive range: 685 to 935 rpm. Alternate motor drive

range: 835 to 1085 rpm. High-static motor drive range is 830 to
1130 rpm. All other rpms require field-supplied drive.

NOTES:

1. Boldface indicates high-static motor and drive are required.
2. Maximum usable watts input is 2120 with standard motor,

2615 with alternate motor, and 4400 for the high-static motor.
Maximum continuous bhp is 2.40 with standard motor, 2.90

with alternate motor, and 5.25 for the high-static motor. Exten-
sive 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. For additional information on motor perfor-
mance, refer to Table 8.

3. Values include losses for filters, unit casings, and wet coils.

See Table 7 for accessory/FIOP static pressure information.

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

your Carrier representative for details.

5. Interpolation is permissible. Do not extrapolate.
