LEGEND AND NOTES FOR TABLES 18 AND 19
LEGEND
NOTES:
1. Boldface indicates field-supplied drive required. (See Note 3.)
2. Motor drive range is 760 to 1090 rpm for standard motors; 1075 to
1455 rpm for high-static motors. All other rpms require a field-supplied
drive.
3. Values include losses for filters, unit casing, and wet coils. See page 28
for accessory/FIOP static pressure information.
4. Maximum continuous bhp is 1.20 for standard motors; 2.40 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 pre-
mature motor failure. Unit warranty will not be affected. See Evaporator-
Fan Motor Data tables on page 20 for additional 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.
