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

LEGEND

*Motor drive range: 900 to 1300 rpm. All other rpms require field-

supplied drive.

NOTES:

1. 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
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.
