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 required. (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 2120 with standard motor and 2615
with alternate motor. Maximum continuous bhp is 2.40 with
standard motor and 2.90 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 nuisance tripping or pre-
mature motor failure. Unit warranty will not be affected. For addi-
tional 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 representative for details.
9. Standard motor drive range: 685 to 935 rpm. Alternate motor drive
range: 835 to 1085 rpm. All other rpms require field-supplied drive.
10. Interpolation is permissible. Do not extrapolate.
11. Minimum allowable cfm is 300 cfm/ton.
