*Standard low-medium static drive range for the 020 size is 910 to 1095 rpm. Standard low-medium static drive range for the 024 size is 1002 to 1225 rpm. Alternate high-static drive range for the 020 size is 1069 to 1287. Alternate high-static drive range for the 024 size is 1193 to 1458 rpm. Other rpms require a field-supplied drive.

NOTES:

1.Maximum continuous bhp for the 020 size is 5.90. Maximum continuous 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 that motor maximum bhp and/or watts is exceeded at the maximum operating cfm.

2.Static pressure losses (i.e., EconoMi$er) must be added to external static pressure before entering Fan Performance table.

3.Interpolation is permissible. Do not extrapolate.

4.Fan performance is based on wet coils, clean filters, and casing losses. See Table 12 for accessory/FIOP static pressure information.

5.Extensive motor and drive testing on these units ensures that the full horsepower and watts range of the motor can be utilized with confidence. Using your fan motors up to the watts or bhp rating shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected.

6.Use of a field-supplied motor may affect wiring size. Contact your Carrier representative for details.
