NOTES:
1. Boldface indicates field-supplied drive required. (See Note 6.)
2. indicates alternate drive required.
3. indicates field-supplied motor and drive required.
4. indicates maximum usable bhp/watts of standard drive.
5. indicates maximum usable bhp/watts of alternate drive.
6. Standard drive range is 590 to 840 rpm. Alternate drive range is 685 to
935 rpm. All other rpms require a field-supplied drive.
7. Values include losses for filters, unit casing, and wet coils.
8. 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 confidence. Using your fan motors
up to the wattage ratings shown will not result in nuisance tripping or prema-
ture motor failure. Unit warranty will not be affected. See Evaporator-Fan
Motor Performance table on page 60 for additional information.
9. Use of a field-supplied motor may affect wire sizing. Contact your local
representative to verify.
10. Interpolation is permissible. Do not extrapolate.
11. Minimum allowable cfm is 300 cfm/ton.
