NOTES:
1. 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.
2. 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 (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 (460 v). Do not
adjust motor rpm such that motor maximum bhp and/or watts is
exceeded at the maximum operating cfm.
3. Static pressure losses (i.e., economizer) must be added to external static
pressure before entering Fan Performance table.
4. Interpolation is permissible. Do not extrapolate.
5. Fan performance is based on wet coils, clean filters, and casing losses.
See Tables 21-23 for accessory/FlOP static pressure information.
6. Extensive motor and drive testing on these units ensures that the full
horsepower and watts range of the motor can be utilized with confi-
dence. Using 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.
7. Use of a field-supplied motor may affect wiring size. Contact your Carrier
representative for details.

NOTES:
1. Standard low-medium static drive range is 1066 to 1283 rpm. Alternate
high-static drive range is 1332 to 1550. Other rpms require a field-
supplied drive.
2. Maximum continuous bhp is 10.2 (208/230, 575 v) or 11.8 (460 v) and
the maximum continuous watts are 9510 (208/230, 575 v) or 11,000
(460 v). Do not adjust motor rpm such that motor maximum bhp and/or
watts is exceeded at the maximum operating cfm.
