Standard low-medium static drive range for the 024 sizeis 1002 to 1225 rpm. Alternate high-static drive range for the 020 sizeis 1069 to 1287. Alternate high-static drive range for the 024 size is1193 to 1458 rpm. Other rpms require a field-supplied drive.NOTES:1. Maximum continuous bhp for the 020 size is 5.90. Maximum con-tinuous bhp for the 024 size is 8.7 (208/230, 575 v) or 9.5 (380,460 v). The maximum continuous watts for the 020 size is 5180.The maximum continuous watts for the 024 size is 7915 (208/230,575 v) or 8640 (380, 460 v). Do not adjust motor rpm such thatmotor maximum bhp and/or watts is exceeded at the maximumoperating cfm.2. Static pressure losses (i.e., economizer) must be added to exter-nal static pressure before entering Fan Performance table.3. Interpolation is permissible. Do not extrapolate.4. Fan performance is based on wet coils, clean filters, andcasing losses. See Table 9 for accessory/FIOP static pressureinformation.5. Extensive motor and drive testing on these units ensures that thefull horsepower and watts range of the motor can be utilized withconfidence. Using your fan motors up to the watts or bhp ratingshown will not result in nuisance tripping or premature motor fail-ure. Unit warranty will not be affected.6. Use of a field-supplied motor may affect wiring size. Contact yourCarrier representative for details.17
