Bhp — Brake Horsepower Input to Fan
FIOP — Factory-Installed Option
Watts — Input Watts to Motor
NOTES:
1. Boldface indicates a field-supplied drive is required. (See Note 9.)
2. indicates alternate drive is required.
3. indicates field-supplied motor and drive are required.
4. indicates maximum usable bhp/watts of standard drive.
5. indicates maximum usable bhp/watts of alternate drive.
6. Maximum usable watts input is 2120 and maximum continuous bhp
is 2.40. Extensive motor and electrical testing on these units
ensures that the full range of the motor can be utilized with confi-
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. For additional information on motor per-
formance, 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 drive range: 590 to 840 rpm. Alternate drive range: 685 to
935 rpm. All other rpms require field-supplied drive.
10. Interpolation is permissible. Do not extrapolate.
11. Minimum allowable cfm is 300 cfm/ton.
