FAN PERFORMANCE — VERTICAL DISCHARGE UNITS (cont)
LEGEND
NOTES:
1.
Boldface
indicates field-supplied drive required. (See Note 3.)
2. indicates field-supplied motor and drive required.
3. Motor drive range is 840 to 1185 rpm for standard motor; 1075 to 1455 rpm
for high-static motor. All other rpms require a field-supplied drive.
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 1.2 for standard motor, 2.4 for high-static motor.
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 premature 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.
