Table 27 — Fan Performance, 548F060 High-Static Motor — Horizontal Discharge Units

LEGEND

*Motor drive range: 1300 to 1685 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. Values include losses for filters, unit casing, and wet coils. See

Table 7 for accessory/FIOP static pressure information.

4. Maximum continuous bhp is 2.9 and the maximum continuous watts

are 2562. 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. See Indoor-Fan Motor Performance,

Table 6 for additional 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.
