3. 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 perfor-
mance, refer to Indoor-Fan Motor Performance table on page 52.
4. Values include losses for filters, unit casing, and wet coils. See
page 49 for accessory/FIOP static pressure information.
5. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
6. Interpolation is permissible. Do not extrapolate.
