Table 17 — Fan Performance, 548F072 Standard Motor — Vertical Discharge Units

LEGEND

*Motor drive range: 1070 to 1460 rpm. All other rpms require field-

supplied drive.

NOTES:

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 confi-

dence. Using your fan motors up to the wattage ratings shown will

not result in nuisance tripping or premature motor failure. Unit war-

ranty will not be affected. For additional information on motor per-

formance, refer to Indoor-Fan Motor Performance, Table 6.

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

Bryant representative for details.

6. Interpolation is permissible. Do not extrapolate.
