Watts — Input Watts to Motor
NOTES:
1. Boldface indicates a field-supplied or alternate (as appropriate) drive is re-
quired. (See Note 9.)
2. indicates alternate motor and drive are required.
3. indicates field-supplied motor and drive are required.
4.
indicates maximum usable bhp/watts of standard motor.
5. indicates maximum usable bhp/watts of alternate motor.
6. Maximum usable watts input is 3775 with standard motor and 4400 with
alternate motor. Maximum continuous bhp is 4.20 with standard motor and
5.25 with alternate motor. 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 nui-
sance tripping or premature motor failure. Unit warranty will not be affected.
7. Values include losses for filters, unit casing, and wet coils. See page 47 for
accessory/FIOP static pressure information.
8. Use of a field-supplied motor may affect wire sizing. Contact your local rep-
resentative for details. For additional information on motor performance, refer
to Evaporator-Fan Motor Performance table on page 62.
9. Standard motor drive range: 860 to 1080 rpm. Alternate motor drive range:
900 to 1260 rpm. All other rpms require field-supplied drive.
10. Interpolation is permissible. Do not extrapolate.
11. Minimum allowable cfm is 300 cfm/ton.
