Table 19 — Fan Performance, 50TFF012 — Horizontal Discharge Units

LEGEND

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

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

NOTES:

1. Boldface indicates field-supplied drive is required.
2.

 indicates high-static motor and drive are required.

3. 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
a alternate motor, and 5.25 for the high-static motor. 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.

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 for details. For additional information
on motor performance, refer to Table 8.

6. Interpolation is permissible. Do not extrapolate.
