NOTES:
1. Boldface indicates field-supplied drive required. (See Note 2.)
2. Motor drive range is 1047 to 1251 rpm. Other rpms require a field-supplied
drive.
3. Static pressure losses (i.e., economizer) must be added to external static pressure
before entering Fan Performance table. See table on page 49 for accessory/
FIOP static pressure information.
4. Interpolation is permissible. Do not extrapolate.
5. Maximum continuous bhp is 5.9 and the maximum continuous watts are 5180.
Extensive motor and drive testing on these units ensures that the full horsepower
range of the motor can be utilized with confidence. Using your fan
motors up to the watts rating shown will not result in nuisance tripping or premature
motor failure. Unit warranty will not be affected. See Evaporator-Fan
Motor Performance table on page 52 for additional information.
6. Fan performance is based on wet coils, clean filters, and casing losses.
7. Use of a field-supplied motor may affect wire sizing. Contact your Carrier representative
for details.
