3. Maximum continuous bhp is 2.4 and the 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 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. See Indoor-Fan Motor Performance table
on page 52 for additional information.
4. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
5. Interpolation is permissible. Do not extrapolate.
