Table 15 — Fan Performance, 50TFF008 Standard Motor and Drive and Alternate Drive —
Horizontal Discharge Units
LEGEND
*Motor drive range: 590 to 840 rpm. Alternate 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 high-static 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 confi-
dence. 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 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 for details.
6. Interpolation is permissible. Do not extrapolate.
