Bhp — Brake Horsepower Input to Fan
FIOP — Factory-Installed Option
Watts — Input Watts to Motor
*Standard motor drive range is 685 to 935 rpm. Alternate motor drive
range is 835 to 1085 rpm. All other rpms require a field-supplied drive.
NOTES:
1. Boldface indicates field-supplied motor and drive are required.
2. Values include losses for filters, unit casing, and wet coils. See
page 52 for accessory/FIOP static pressure information.
3. Maximum continuous bhp is 2.4 for the standard motor and 2.9 for
the alternate motor. Maximum continuous watts are 2120 for the
standard motor and 2615 for the 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. See
Evaporator-Fan Motor Performance table on page 55 for additional
information.
4. Use of a field-supplied motor may affect wire sizing. Contact your
local representative for details.
5. Interpolation is permissible. Do not extrapolate.
