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 confidence. Using your fan motors up to the wattage rat-
ings shown will not result in nuisance tripping or premature
motor failure. Unit warranty will not be affected. For additional
information on motor performance refer to Table 8.
4. Values include losses for filters, unit casing, and wet coils. See
Table 7 for accessory/FIOP static pressure information.
5. Use of a field-supplied motor may affect wire sizing. Contact
your Carrier representative to verify.
6. Interpolation is permissible. Do not extrapolate.
