NOTES:

1.Boldface indicates field-supplied drive required. (See Note 3.)

2. indicates field-supplied motor and drive required.

3.Motor drive range is 1120 to 1585 rpm for standard motors; 1300 to 1685 rpm for high-static motors. All other rpms require a field-supplied drive.

4.Values include losses for filters, unit casing, and wet coils. See page 40 for accessory/FIOP static pressure information.

5.Maximum continuous bhp is 2.4 for standard motors; 2.9 for high-static motors. 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 ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected. See Evaporator-Fan Motor Data tables on pages 41 and 42 for additional information.

6.Use of a field-supplied motor may affect wire sizing. Contact your Bryant rep- resentative to verify.

7.Interpolation is permissible. Do not extrapolate.
