Watts — Input Watts to Motor
*Motor drive range is 1070 to 1460 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 and maximum continuous watts are
2120. 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. 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.
