4. Values include losses for filters, unit casing, and wet coils. See page 49 for
accessory/FIOP static pressure information.
5. Maximum continuous bhp is 2.90 for standard motors, 4.20 for high-static
motors. 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 ratings shown will not result in nuisance tripping or prema-
ture motor failure. Unit warranty will not be affected. See Evaporator-Fan
Motor Data tables on pages 47 and 48 for additional information.
6. Use of a field-supplied motor may affect wire sizing. Contact your Carrier
representative to verify.
7. Interpolation is permissible. Do not extrapolate.
