*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.
Refer to this page for general Fan Performance Data notes.
NOTE: Maximum continuous bhp is 10.20 (208/230, 575 v) or 11.80 (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. See Table 25 for more
information.

GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES
1. Static pressure losses (i.e., economizer) must be added to external
static pressure before entering Fan Performance table.
2. Interpolation is permissible. Do not extrapolate.
3. Fan performance is based on wet coils, clean filters, and casing losses.
See Table 23 for accessory/FIOP static pressure information.
4. 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 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.
5. Use of a field-supplied motor may affect wire size. Contact your Carrier
representative for details.
