Table 29 — Fan Performance, 548F072 High-Static Motor — Horizontal Discharge Units)
LEGEND
*Motor drive range: 1300 to 1685 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. Values include losses for filters, unit casing, and wet coils. See
page 47 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.
