*Standard drive range is 590 to 840 rpm. Alternate drive range is 685 to 935 rpm. All other rpms require a ®eld-supplied drive.

NOTES:

1.Boldface indicates ®eld-supplied motor and drive are required.

2.Values include losses for ®lters, unit casing, and wet coils. See page 52 for accessory/FIOP static pressure information.

3.Maximum continuous bhp is 2.40 and the maximum continuous watts are 2120. Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with con®- 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 Evaporator-Fan Motor Performance table on page 55 for additional information.

4.Use of a ®eld-supplied motor may affect wire sizing. Contact your local representative for details.

5.Interpolation is permissible. Do not extrapolate.
