Bhp — Brake Horsepower Input to Fan
FIOP — Factory-Installed Option
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 al-
ternate motor. Maximum continuous bhp is 4.20 with standard motor and 5.25
with alternate motor. Extensive motor and electrical testing on these units en-
sures 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 premature motor failure. Unit warranty will not be affected. For ad-
ditional information on motor performance, refer to Evaporator-Fan Motor
Performance table on page 62.
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.
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.
