Table 25 — Fan Performance, 548F060 Standard Motor — Horizontal Discharge Units

LEGEND

NOTES:

1. Values include losses for filters, unit casing, and wet coils. See

Table 7 for accessory/FIOP static pressure information.

2. 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. For additional information on motor performance, refer

to Indoor-Fan Motor Performance, Table 6.

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

Bryant representative for details.

Table 26 — Fan Performance, 548F060 Alternate Motor — Horizontal Discharge Units

*Motor drive range: 900 to 1300 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 1.30 for single-phase units and 2.40 for 3-phase units. 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. For additional information on motor performance, refer to
